(3) An illegal board (impersonated board) is provided between the main control board and the peripheral board, and the ROM of (2) above is replaced.

  In order to prevent such illegal acts, there are the following conventional gaming machines. That is, this gaming machine is connected to the main control unit (main control unit) that determines whether or not the privilege can be granted and stores the third identification information, and stores the first identification information. A first sub-control unit (first peripheral unit), and a second sub-control unit (second peripheral unit) connected to the main control unit and storing second identification information. In this gaming machine, information can be output only from the main control unit toward the first peripheral part, and the main control part and the second peripheral part can mutually input and output information. The second peripheral part has means for outputting the second identification information to the main control part. On the other hand, the main control unit has means for outputting the second identification information and the third identification information to the first peripheral portion. The first peripheral portion includes a computing unit that performs a predetermined computation using the first identification information, the second identification information, and the third identification information, and whether or not the gaming machine has been illegally modified based on a computation result of the computing unit. Means for determining whether or not (see, for example, Patent Document 1). Hereinafter, this technique is referred to as a first conventional example.

  In addition, the conventional gaming machine includes a symbol display device that displays a jackpot symbol, a main control device (main control unit) that transmits data to the symbol control unit according to the game situation, and a main control unit that responds to the game situation. Some include a symbol control unit (peripheral unit) that controls the symbol display device based on received control data. In this pachinko gaming machine, the main control unit performs encryption corresponding to the first key data on the first storage means for storing the first key data and the control data for controlling the operation of the symbol control unit.

In this pachinko gaming machine, when the control command to be transmitted to the peripheral unit is a predetermined control command, the main control unit adds authentication data for authenticating the main control unit to the predetermined control command and transmits it to the peripheral unit. To do. When the peripheral unit receives a predetermined control command, the peripheral unit authenticates the main control unit based on the authentication data transmitted in addition to the predetermined control command (see, for example, Patent Document 3). Hereinafter, this technique is referred to as a third conventional example.

  In the first conventional example, the CPU mounted on the first peripheral part that controls the lamp, the speaker, etc. performs a predetermined calculation using the first identification information, the second identification information, and the third identification information to control the display. The CPU mounted on the second peripheral portion determines whether or not the gaming machine has been illegally modified based on the calculation result.

  As described above, in order to cause the CPU to execute the authentication process in addition to the existing process (for example, the effect process), it is necessary to add processes such as an authentication function and an authentication timing to the existing process. For this reason, a great deal of time and effort is spent on the design of the authentication timing for adding the authentication function, the realization of the authentication function, the simulation of the operation, and the verification (verification) to confirm whether the desired function can be obtained. Therefore, there is a problem that it takes a lot of time and effort to develop a gaming machine. Such a problem particularly appears when changing the model of a gaming machine. Furthermore, with the recent diversification of the effects of gaming machines, the code size of programs to be executed by the CPU tends to become enormous, so the above problem is further increased by adding an authentication function.

  In addition, when the CPU performs authentication processing in addition to the existing processing, the processing load of the CPU increases, so the processing speed decreases, display for production is not performed smoothly, or in the worst case There was a problem that the authentication process itself could not be added. In particular, in recent years, in order to improve the interest of the game, there is a tendency that the effects of appealing to the visual and auditory senses of the player at the time of reach, jackpot, etc. are diversified, and the possibility that the above problem will occur increases.

  In the first conventional example, one CPU constituting the peripheral part performs only one authentication process (ID addition process). Further, by causing the CPU configuring the peripheral portion to execute the authentication process in addition to the existing processing, the processing load of the CPU configuring the peripheral portion increases. Therefore, it is difficult to cause the CPU configuring the peripheral portion to execute authentication processing by a more complicated calculation and authentication processing multiple times than ever in order to further enhance security.

  On the other hand, in the second conventional example, in the main control unit, the encryption unit performs encryption corresponding to the first key data on the control data for controlling the operation of the symbol control unit, and the first key change unit The first key data is changed at a predetermined timing. In the peripheral unit, the authenticating unit performs processing corresponding to the second key data on the encrypted data received from the main control unit, thereby determining the validity of the received encrypted data. Authentication is performed, and the second key data is changed to correspond to the first key data at a predetermined timing so that the second key changing means matches the change timing of the first key data. That is, the main control unit and the peripheral unit perform sophisticated and complicated encryption processing and authentication processing. Therefore, in the second conventional example, since the processing load of both the CPU constituting the main control unit and the CPU constituting the peripheral part increases, the processing speed decreases, and the basic process and the effect process accompanying the progress of the game content. The original process may not be performed smoothly.

  Further, in the third conventional example, as in the first conventional example, when the peripheral CPU executes an authentication process in addition to the existing game process, authentication data is added to a predetermined control command and the peripheral process is performed. Even if it is transmitted to the part, the processing load on the CPU in the peripheral part increases, so the processing speed decreases, the display for presentation is not performed smoothly, or it is difficult to add the authentication process itself It is conceivable that there will be restrictions. In recent years, in particular, in order to improve the interest of the game, there is a tendency for various effects to appeal to the visual and auditory sense of the player regarding the control of the variation of the pattern. Therefore, it is desirable to construct a gaming machine provided with an authentication unit that reduces the load of performing an authentication process on a peripheral part (image control part) that performs various effects control.

  Further, by causing the CPU constituting the peripheral portion to execute the authentication process in addition to the existing processing, the processing load and program capacity of the CPU constituting the peripheral portion are increased. Therefore, it is difficult to cause the CPU configuring the peripheral portion to execute authentication processing by a more complicated calculation and authentication processing multiple times than ever in order to further enhance security.

  By the way, a gaming machine may malfunction when external electrical noise or mechanical vibration is applied. For example, when a control command is transmitted from the main control unit to the peripheral part, if noise such as electromagnetic waves or static electricity is added from the outside of the gaming machine, a bit error occurs in the control command data due to the influence of the noise, and control is performed. A malfunction occurs that the command is changed. In this case, if a bit error occurs and the control command is changed to a jackpot command even though the control command that should be transmitted to the peripheral part is a control command other than the jackpot command, an illegal action is performed. Even if this is not the case, an unreasonable amount of game media is paid out to the player, and the game store suffers a great deal of damage. However, in the first to third conventional examples, no countermeasures are taken for the problem caused by such a malfunction, so that the problem that the game shop suffers a great deal of damage cannot be solved.

  The present invention has been made in view of the above circumstances, and can detect fraudulent acts and malfunctions of gaming machines due to replacement of a regular main control board and an unauthorized main control board of a gaming machine.

<< Embodiment 1 >>
Hereinafter, Embodiment 1 which is a form for implementing this invention with reference to drawings is demonstrated.
FIG. 1 is a block diagram showing a functional configuration of a pachinko gaming machine 1 that is one of gaming machines according to Embodiment 1 of the present invention. The pachinko gaming machine 1 includes a main control unit 10, a rear stage unit 20, and a peripheral unit 30. The main control unit 10 includes data storage means 11, determination means 12, individual test value generation means 13, and action test value generation means 14. Data such as a program used in the main control unit 10 is stored in the data storage unit 11. The determination unit 12 determines the number of divisions that is the number of predetermined data among the data stored in the data storage unit 11. Here, the predetermined data is all or a part of the data stored in the data storage unit 11.

  The individual test value generation unit 13 generates an individual test value used for authenticating the identity (identity) of the main control unit 10 as an individual (hereinafter referred to as individual authentication). Specifically, the individual test value generation unit 13 divides predetermined data stored in the data storage unit 11 by the number of divisions determined by the determination unit 12, and satisfies the combination rule for each divided data. Binary operation (for example, addition, multiplication, exclusive OR) is performed to generate individual test values for the number of divisions (the same number as the number of divisions).

  The motion inspection value generation means 14 outputs various data signals (for example, control commands output by the main control unit 10 to cause the peripheral unit 30 to perform a certain effect process) for each processing operation of the main control unit 10. Authentication (whether the operation signal of the pachinko gaming machine 1 has continuity) is authenticated (hereinafter, operation authentication). The operation inspection value used for the above is generated.

  Specifically, the operation inspection value generation means 14 uses a plurality of synchronizations as packet inspection information generated with the processing operation of the main control unit 10 (for example, output of a control command) as one of the operation inspection values. Generate code. This packet information is generated so that two pieces of continuously generated packet information have a predetermined correlation set in advance, so that the difference between the received packet information always has a predetermined correlation. If it does, it will be understood that the processing operation of the main control unit 10 is executed in the normal operation order. Packet information is classified into a plurality of types according to the difference in correlation. In addition, the motion test value generation unit 14 selects the next time out of a plurality of types of packet information based on the number of individual test values generated by the individual test value generation unit 13 (the number of divisions determined by the determination unit 12). Select the type of packet information used to generate the synchronization code.

  The main control unit 10 includes a plurality of pieces of individual authentication data for the number of divisions obtained by performing encryption processing on the individual test values for the generated number of divisions and a plurality of generated synchronization codes. Each of the plurality of operation authentication data obtained by performing the encryption process on the operation inspection value is added to the control command to be output and transmitted to the subsequent stage unit 20 or the peripheral unit 30.

  On the other hand, the rear stage unit 20 includes an expected value storage unit 21 and an intermediate authentication unit 22. The expected value storage unit 21 is information that uniquely represents a predetermined correlation preset in advance for each type of packet information included in the synchronization code generated by the operation test value generation unit 14 that constitutes the main control unit 10. It is stored in advance as an expected value (hereinafter referred to as an intermediate operation authentication expected value). The intermediate authentication unit 22 performs intermediate operation authentication using the operation authentication data transmitted from the main control unit 10 via the peripheral unit 30.

  Specifically, the intermediate authentication unit 22 first performs intermediate operation authentication as operation authentication for the processing operation of the main control unit 10 using the operation authentication data transmitted from the main control unit 10 via the peripheral unit 30. . In the intermediate operation authentication, the synchronization code is extracted from the operation authentication data transmitted from the main control unit 10, and in order to confirm whether the packet information included in the extracted synchronization code has a predetermined correlation set in advance, The difference (not limited to subtraction) between the two pieces of packet information generated in this way is obtained.

  In addition to the basic operation control related to the game of the pachinko gaming machine 1 as outlined above, the main control unit 10 is a process related to authentication of the main control unit 10 for preventing fraud, which is a feature of the first embodiment. Means for executing. The means for executing the processing relating to the authentication is realized by the CPU 10a executing a program (program code) stored in advance in the ROM 10b. The processing related to this authentication is as follows [1] to [7], but the encryption processing shown in [3] and the like is executed as necessary.

[1] Determination of the number of divisions The main control unit 10 determines the number of divisions, which is a number for dividing predetermined data stored in advance in the ROM 10b, for example, predetermined program codes (instruction codes and fixed data). Hereinafter, as an example of the predetermined data, description will be given using a predetermined program code. The main control unit 10 uses, for example, a value generated by a random number generation circuit (not shown) or a random number generation program constituting the program code as a division number, or a value generated in other processing of the main control unit 10. The value can be referred to at a predetermined timing and the value can be used as the division number. In this case, the upper limit of the number of divisions may be set in advance. The means for executing the process for determining the number of divisions can correspond to, for example, the determination means 12 shown in FIG. In the first embodiment, the main control unit 10 determines the number of divisions using random numbers, but this is an example for determining the number of divisions, and determines the number of divisions without using random numbers. You may make it do. For example, the main control unit 10 holds a table for determining the number of divisions in advance, and the main control unit 10 obtains the number of divisions from the table according to a predetermined rule at the timing of determining the number of divisions. You may do it.

[2] Generation of Individual Examination Value Next, the main control unit 10 divides the storage area in which a predetermined program code in the ROM 10b is stored in advance by the number of divisions determined in the process [1]. Then, the main control unit 10 performs a binary operation on the program code stored in each divided storage area of the ROM 10b, and the individual test values for the number of divisions for individual authentication of the main control unit 10 Is generated. Note that the same method is used in advance between the main control unit 10 and the effect control unit 203 for the individual test value generation method (for example, the type of binary operation that satisfies the combination rule used for generating the individual test value). Just set it up.

“Binary operation satisfying the join rule” means that among the binary operations that perform operations between two terms, if the operator is § and any number is a, b, c, formula (1) holds Binary operation.
(A§b) §c = a§ (b§c) = a§b§c (1)
In other words, “binary operation satisfying the combination rule” is a case where the operation objects a, b, and c are divided as operation objects to be subjected to binary operation at a time and are operated by the operator §. Is also a binary operation in which the obtained calculation results have the same value. However, an operator ♪ in which the operation result of a ♪ b is always 0 for any number a and b is excluded from the operator §. Since a defined set of binary operations that satisfy the above-mentioned combination rule is generally called a semigroup, such a binary operation is hereinafter referred to as a semigroup operation. Examples of the semi-group operation include addition, multiplication, and exclusive OR.

Hereafter, two simple specific examples of the semigroup operation will be given.
First, each data constituting each data block obtained by dividing a predetermined program code is defined as D0, D1, D2,..., DN (N is the final address of each data block).
(A) If addition (operator +) is selected as the semi-group operation, equation (2) is calculated.
D0 + D1 + D2 + ... + DN (2)
(B) When an exclusive OR (operator XOR) is selected as the semi-group operation, Equation (3) is calculated.
D0 XOR D1 XOR D2 XOR ... DN (3)

A method for generating each individual test value will be described with reference to FIG.
FIG. 4 is an explanatory diagram schematically showing a method for generating an individual test value in the main control unit 10. The individual test value is generated by the main control unit 10 using predetermined data stored in advance in the ROM 10b. More specifically, the main control unit 10 divides a predetermined storage area of the ROM 10b by an arbitrary number of divisions, and then performs a binary operation that satisfies the combining law for each program code stored in the divided storage area ( An individual test value is calculated by performing a semi-group operation. Examples of the semi-group operation include addition, multiplication and exclusive OR operation as described above.

(Example of individual test value generation calculation)
An example of calculation of individual test value generation is shown below.
In the program code storage area 400 shown in FIG. 4, 12 program codes (“0x01” to “0x09”, “0x0A” to “0x0C”) are stored. When the division number is 3, the program code storage area 400 is, for example, a first block 400a including four program codes, a second block 400b including three program codes, and a third block including five program codes. It can be divided into blocks 400c. The main control unit 10 performs a semi-group operation on the program code stored in each of these blocks to calculate an individual test value. The number of program codes in the block is an example. The number of program codes in the divided block may be a fixed value or may be determined randomly.

  For example, if the method using the addition of Expression (2) as the semi-group operation is Method A, the four program codes “0x01”, “0x02”, “0x03”, “0x04” stored in the first block 400a are used. The first individual test value “0x0A” is obtained by addition. Similarly, three program codes “0x05”, “0x06”, “0x07” stored in the second block 400b are added, and the second individual test value “0x12” is stored in the third block 400c. The third individual test value “0x32” is obtained by adding the program codes “0x08”, “0x09”, “0x0A”, “0x0B”, “0x0C”.

  Further, for example, if the method using the exclusive OR operation of Expression (3) as the semi-group operation is method B, the four program codes “0x01”, “0x02”, “0x03” stored in the first block 400a are used. ”And“ 0x04 ”to perform an exclusive OR operation to obtain a first individual test value“ 0x04 ”. Similarly, exclusive OR operation is performed on the three program codes “0x05”, “0x06”, and “0x07” stored in the second block 400b, and the second individual test value “0x04” is stored in the third block 400c. A third individual test value “0x0C” is obtained by performing an exclusive OR operation on the five stored program codes “0x08”, “0x09”, “0x0A”, “0x0B”, and “0x0C”.

In the first embodiment, as will be described later, the main control unit 10 generates data for authenticating the normality of the pachinko gaming machine 1, and adds the generated data to the control command to add the subsequent stage unit 20 or the production. It transmits to the control part 203. Here, data for authenticating the authenticity of the main control unit 10 added to the control command is collectively referred to as “individual authentication data”. The individual authentication data is data obtained by performing encryption processing on each individual test value or these individual test values. Further, data for authenticating the continuity of the operation of the pachinko gaming machine 1 added to the control command will be collectively referred to as “operation authentication data”. The operation authentication data is data obtained by performing encryption processing on each operation inspection value or these operation inspection values. Hereinafter, in the first embodiment, the individual authentication data or the operation authentication data will be described as data obtained by performing encryption processing on the individual inspection value or the operation inspection value, but the present invention is not limited to this, Processing related to authentication may be performed using the individual test value or the operation test value itself as the individual authentication data or the operation authentication data. In this case, it is not necessary to perform encryption processing on the individual test value or the operation test value in the main control unit 10, and when the individual test value or the operation test value is extracted in the subsequent stage unit 20 or the production control unit 203, the individual authentication data or Since it is not necessary to decrypt the operation authentication data, it is possible to simplify the process related to authentication and suppress an increase in processing load.
The means for executing the process for generating the individual test value can correspond to, for example, the individual test value generation means 13 shown in FIG.

[3] Generation of Individual Authentication Data The main control unit 10 performs an encryption process on each individual test value generated in the process [2] and adds an individual to the control command (control command data and accompanying data). Generate authentication data. Here, as an encryption method, for example, a relatively simple method such as Caesar encryption, single substitution encryption, or enigma can be employed. The same applies to the encryption method used below. Caesar encryption is an encryption method in which characters constituting a message (plain text) are encrypted by shifting by a certain number of characters. Single substitution cryptography is an encryption scheme that encrypts characters by converting the characters constituting the plaintext into other characters. Enigma is set with Enigma using key encryption key, Encrypt communication key with Enigma, Enigma Enigma with communication key, plaintext encryption, encrypted communication key and encrypted This is an encryption method through a process of generating a communication text by combining plaintext.

  In the main control unit 10, when each individual authentication data obtained by performing encryption processing on each individual test value is transmitted to the effect control unit 203, each individual test value that has not been subjected to any processing is obtained. Compared with the case of transmitting to the effect control unit 203 as it is, it is possible to reduce the possibility that each individual test value is analyzed by an unauthorized person. The main control unit 10 may perform different encryption processing for each individual test value.

  A predetermined processing process may be further added to the encryption process. As the predetermined processing, for example, a process of obtaining arithmetic data having a predetermined data length by performing four arithmetic operations or logical operations using the individual test values subjected to encryption processing, these four arithmetic operations or logical Extracting a plurality of bits constituting each individual test value subjected to processing for rearranging the bit arrangement of operation data obtained by operation, processing for shifting or rotating the bits of operation data, and encryption processing For example, a process of generating one piece of data arranged in accordance with a predetermined rule can be considered.

(Calculation example for generating individual authentication data)
An example of calculation for generating individual authentication data is shown below.
An example of generating individual authentication data from the first individual test value “0x0A” shown in FIG. 4 will be described. As the encryption process, a process of adding control command data to the individual test value and then subtracting “0x03” from the obtained data is employed. The main control unit 10 performs the above-described encryption processing on the first individual test value to generate individual authentication data.

The values of the control command data and the accompanying data to which the individual authentication data is added are assumed to be “0xEE” and “0x01”. In the encryption process, since the value “0xEE” of the control command data is added to the first individual inspection value “0x0A”, “0xF8” is obtained. Next, by subtracting “0x03” from this “0xF8”, the value “0xF5” of the individual authentication data is obtained.
Similarly, when individual authentication data is generated from the second individual test value “0x12” recorded in the program code storage area 400 shown in FIG. Is generated, the value becomes “0x1D”.

  Note that the individual authentication data may be generated by performing an encryption process on the data including the individual test value and the control command data transmitted along with the individual authentication data or at least one of the accompanying data. The individual authentication data may include control command data transmitted along with the individual authentication data and data related to the accompanying data. Data related to control command data and accompanying data is the above processing, control using a hash function, parity check, cyclic redundancy check (CRC), checksum, etc. for control command data and accompanying data. It is the value obtained by going.

  By generating the individual authentication data using the control command data and accompanying data transmitted together with the individual authentication data, even if the individual authentication data is reused by an unauthorized control unit, the individual authentication data and the control command Mismatch is not possible and fraud can be detected. Further, even if the control command data is changed due to a malfunction, authentication is not successful, so that execution of the control command corresponding to the control command data changed due to the noise or the like can be prevented.

  When the individual authentication data includes data related to control command data and accompanying data, the main control unit 10 performs encryption processing by combining the data related to the control command data and accompanying data and the individual test value, and the individual authentication data. You may perform the process which produces | generates.

  The timing at which the main control unit 10 generates each individual test value and the timing at which individual authentication data is generated using each individual test value are not particularly limited, and in the control program of the main control unit 10, What is necessary is just to incorporate the program which performs the process which produces | generates each individual test value, and the process which produces | generates individual authentication data using each individual test value.

[4] Generation of Operation Inspection Value The main control unit 10 adds the control command data and accompanying data to effect control in order to authenticate the continuity of the operation of the pachinko gaming machine 1 in the rear stage unit 20 and the effect control unit 203. A synchronization code is generated as an operation inspection value to be transmitted to the subsequent stage unit 20 via the unit 203, and stored in an operation inspection value memory which is a predetermined storage area of the RAM 10c. Hereinafter, generation of the synchronization code will be described in detail.

{1} Generation of synchronization code The main control unit 10 is generated along with the processing operation having the continuity of the main control unit 10 in order to authenticate the continuity of the operation of the pachinko gaming machine 1 as one of the operation inspection values. Packet information is generated, and the generated packet information is acquired to generate a synchronization code. The packet information is information that can authenticate that the main control unit 10 is operating continuously. When packet information at successive generation timings is compared, the packet information is generated between each other (a predetermined interval). A predetermined correlation caused by a time interval, a predetermined clock number interval, or an instruction execution number interval). In the first embodiment, it is assumed that packet information is generated with the output of the control command of the main control unit 10, and the difference between the packet information generated at the generation timing according to the output timing of the continuous control command is It is generated so as to have a predetermined correlation set. The side receiving the packet information generated in this way, if the difference between the packet information always has a predetermined correlation, the control commands of the main control unit 10 are output in the normal operation order. It can be judged.

  The relationship between the timing at which the main control unit 10 generates packet information and the timing at which it is acquired is set so as to be acquired at each timing at which packet information is generated, or is different from the timing at which packet information is generated. Although it can be set to be acquired at the timing, in the first embodiment, it is acquired at every timing when the packet information is generated.

  The packet information generated with the operation of the main control unit 10 can be classified into the following two types, for example, according to the generation interval. Specifically, the main control unit 10 continuously generates packet information (continuous packet information) with the output of the control command, and packet information generated at specific intervals with the output of the control command ( Intermittent packet information).

  The continuous packet information is packet information generated by at least two (two times) continuous timings generated by the main control unit 10. Here, the generation timing according to the processing speed of the main control unit 10 will be described as an example of the generation timing of the continuous packet information. If packet information can be generated for each clock timing, the continuous packet information is generated for each clock timing. If packet information can be generated every 4 clock timings, every 4 clock timings become the generation timing of continuous packet information. At this time, the main control unit 10 generates packet information at every clock timing, acquires the packet information at every clock timing, and sets it as continuous packet information.

The intermittent packet information is packet information generated by at least two (twice) timings (timing at specific intervals) of the packet information generated by the main control unit 10. Here, the timing for each specific interval means, for example, that continuous generation timings are intermittent with a specific interval. The reference of this interval may be based on clock timing such as every 1 clock timing or every 4 clock timings, or may be based on a time such as 1 second or 0.5 seconds.
Specifically, the intermittent packet information is a part of the predetermined generation timing at which the continuous packet information is generated by the main control unit 10, and at least intermittently generated at specific intervals. Two (two times) packet information. For example, when the main control unit 10 can output the packet information at every clock timing, the generation timing of the intermittent packet information can be set as the generation timing of the intermittent packet information every two clock timings. At this time, the main control unit 10 generates packet information every two clock timings, acquires packet information every two clock timings, and sets it as intermittent packet information.

  Thus, when generating a synchronization code using packet information, each packet information is set to a predetermined generation interval, for example, a predetermined time interval, a predetermined clock number interval, or an instruction execution number interval. Generated at the generation timing. At this time, pieces of packet information at successive generation timings are generated as information having a predetermined correlation. That is, the correlation between continuously generated packet information differs between continuous packet information generated continuously and intermittent packet information generated intermittently with a specific interval, Each of the continuous packet information and the intermittent packet information has a predetermined correlation. Therefore, on the side receiving these packet information, a difference (not limited to subtraction) between a plurality of pieces of packet information at successive generation timings is obtained, and the information indicated by the obtained difference value is a predetermined correlation set in advance. If the relationship is indicated, the type of packet information used in the main control unit 10 can be specified, and the processing operation of the main control unit 10 can be continuously performed in a normal operation order by checking at any time. You can verify that it is running.

  In addition, when generating a synchronization code using packet information, one synchronization code may be generated using one packet information, or one or more synchronization codes may be generated using a plurality of packet information. Also good. However, when generating one synchronization code using one packet information so that the correlation between transmitted packet information can be confirmed in the intermediate operation authentication in the later stage unit 20 described later, a plurality of synchronization codes are used. , And the transmission is performed one or more times to the subsequent stage unit 20 via the effect control unit 203. As the synchronization code, values generated as packet information may be used as they are, or values obtained by performing a predetermined operation on these values may be used.

  The main control unit 10 generates the synchronization code using intermittent packet information or generates the synchronization code using continuous packet information, that is, the type of packet information used for generating the synchronization code is based on the number of divisions. Selection can be made according to a predetermined convention. The predetermined agreement is shared by the main control unit 10, the rear stage unit 20, and the effect control unit 203, and includes the following. For example, when the current division number is an odd number, the main control unit 10 selects a packet information type used for generating the next synchronization code that is different from the type used this time, and the current division number is an even number. Selects the same type of packet information used for generation of the next synchronization code as the type used this time. Note that the first packet information type is set in advance to use the same method among the main control unit 10, the subsequent stage unit 20, and the effect control unit 203.

  Other predetermined arrangements include, for example, a method of determining packet information to be selected for each division number, such as intermittent packets in the case of division number 2, continuous packets in the case of division number 3 and so on. A method of assigning the type of packet information to the remainder when dividing the determined number of division by a predetermined specific value X, the absolute value when the previously determined number of divisions is subtracted from the number of divisions determined this time There is a method of assigning packet information types to values.

  The main control unit 10 selects the type of packet information used for generation of the synchronization code based on the value of the number of divisions known only by the main control unit 10, thereby allowing the fraudulent person to select which type of packet information for generating the synchronization code. Can be prevented from being known. Thereby, it is possible to prevent the synchronization code from being illegally generated. Hereinafter, in the first embodiment, as a predetermined agreement, when the number of divisions is an odd number, the type of packet information used for generating the synchronization code is changed, and when the number of divisions is an even number, the type of packet information currently used is changed. In the following description, it is assumed that the first packet information type is a continuous packet. The means for executing the process for generating the synchronization code can correspond to, for example, the operation inspection value generation means 14 shown in FIG.

  Further, in the first embodiment, along with the output of the control command of the main control unit 10, the continuous packet information for generating the packet information at every output and the output of the control command of the main control unit 10 are accompanied. The synchronization code is generated using two types of intermittent packet information that generates packet information at specific intervals instead of every output, but the generation timing of the synchronization code is not limited to this in the present invention. The synchronization code may be generated at a timing before the output process of the control command. Specifically, the synchronization code is a synchronization code corresponding to the timing set by the user of the main control unit 10 (not a player, for example, an administrator or a trader who installs the main control unit 10 in a gaming machine). Can be generated. With such a configuration, the synchronization code can be made information that is more difficult for a third party to analyze.

[5] Generation of Operation Authentication Data The main control unit 10 may perform an encryption process on each synchronization code generated by the process {1} in [4] above. Here, as the encryption method, the same method as that used when generating the individual authentication data can be considered. The encryption process performed when generating the individual authentication data and the encryption process performed when generating the operation authentication data may be the same encryption process or different encryption processes. Also, different encryption processing may be performed for each synchronization code.

  When each synchronization code subjected to the encryption processing in the main control unit 10 is transmitted to the subsequent stage unit 20 via the effect control unit 203, the effect control unit 203 is used as it is for each synchronization code that has not been subjected to any processing. Compared with the case where it transmits to the back | latter stage part 20 via this, possibility that each synchronous code will be analyzed by the fraudulent person can be reduced. Note that a predetermined processing process may be further added to the encryption process as in the case of generating the individual authentication data.

  In addition, encryption processing may be performed on data in which at least one of control command data or accompanying data transmitted together with the synchronization code and the synchronization code are combined. The synchronization code may include control command data and accompanying data transmitted together with the synchronization code.

  Note that methods such as encryption processing and decryption processing may be determined in advance between the main control unit 10, the subsequent stage unit 20, and the effect control unit 203. For example, when the main control unit 10 performs the encryption process on the operation inspection value using the first encryption method and generates the operation authentication data, the subsequent unit 20 uses the decryption method corresponding to the first encryption method. The decryption process is performed, the operation check value is extracted, and the process related to authentication is performed. Thereafter, the post-stage unit 20 performs an encryption process on the obtained result using the second encryption method, and generates intermediate authentication information to be described later. The effect control unit 203 performs a decryption process using a decryption method corresponding to the second encryption method, extracts a result obtained by the subsequent stage unit 20, and performs a process related to authentication. This is not limited to the generation of operation authentication data and the extraction of operation inspection values, and the same applies to the generation of individual authentication data and the extraction of individual inspection values.

In addition, the main control unit 10 prepares a plurality of methods such as encryption processing used for generating individual authentication data or operation authentication data in advance, and determines the number of current divisions (data block of the data block) determined in the process [1]. Based on the number, one encryption process used for generating the next operation authentication data may be selected from a plurality of encryption processes. Specifically, for example, when the current number of divisions is an odd number, the main control unit 10 selects the next encryption process different from the encryption process used this time, and when the current number of divisions is an even number, The next encryption process is the same as the encryption process used this time. At this time, the selection method of the method such as the decryption process is the same as that of the method such as the encryption process, for example, the next time according to the selection information of the decryption method based on the current combination number and the current combination number described later. What is necessary is just to decide beforehand between the main control part 10, the back | latter stage part 20, and the production | generation control part 203 so that the decoding system corresponding to the encryption system used may be selected.
It should be noted that these encryption processes in general also apply to authentication-related data and information signal generation processing in the post-stage unit 20 and the effect control unit 203, such as generation of intermediate authentication information in the post-stage unit 20 described later. .

[6] Adding data to the control signal The main control unit 10 adds the individual authentication data and the operation authentication data to the control command data and accompanying data transmitted to the effect control unit 203 to generate a control signal with authentication data. . Hereinafter, the individual authentication data and the operation authentication data are also referred to as authentication data.

[7] Transmission of control signal The main control unit 10 transmits a control signal with authentication data to the rear stage unit 20 via the effect control unit 203 and the effect control unit 203.

  Here, an example of a data format of a control signal transmitted from the main control unit 10 to the effect control unit 203 will be described with reference to a schematic diagram shown in FIG. FIG. 5A shows a normal control signal 310 including control command data 301 and accompanying data 302. The control command data 301 is data unique to the control command. The accompanying data 302 is data accompanying the control command data 301, and is control data necessary for executing processing corresponding to the control command data 301 such as data indicating the current gaming state, for example.

  On the other hand, when transmitting the authentication data to the effect control unit 203, the main control unit 10 adds the individual authentication data 303 and the operation authentication data 304 in addition to the control command data 301 and the accompanying data 302 as shown in FIG. Is generated and output. The individual authentication data 303 includes an individual test value, and the operation authentication data 304 includes a synchronization code 304a.

  Although not shown in FIG. 5, the normal control signal 310 and the control signal with authentication data 320 include a BCC (Block Check Character) and the like, as with a control signal transmitted in general data communication. Sometimes it is. The BCC is an error detection code added to each transmission block in order to check data errors that occur in the data transmission process.

  The control signal with authentication data 320 is a control signal with authentication data 320 arranged in the order of control command data 301, accompanying data 302, individual authentication data 303, and operation authentication data 304 as shown in FIG. Not limited to these, they may be arranged in any order. For example, the individual authentication data 303 or the operation authentication data 304 may be provided at the head of the control signal, or the individual authentication data 303 or the operation authentication data 304 may be inserted between the control command data 301 and the accompanying data 302.

In this way, by including the individual authentication data 303 and the operation authentication data 304 in the control signal, compared with the case where the individual authentication data 303 or the operation authentication data 304 is transmitted alone, the main control unit 10 and the subsequent stage unit 20 and An increase in communication load with the effect control unit 203 can be suppressed, and the risk that the individual authentication data 303 or the operation authentication data 304 is extracted from the data being communicated and analyzed is reduced. it can.
In addition, as for the transmission format of various data and information signals such as the data format of these control signals, the post-stage unit 20 and the effect control such as a control signal with operation authentication data transmitted from the effect control unit 203 described later to the post-stage unit 20 are used. The same applies to the transmission form of data and information signals related to authentication in the unit 203.

<Rear part>
The rear stage unit 20 includes a CPU 20a, a ROM 20b, a RAM 20c, and the like. The CPU 20a performs processing based on a program (program code) stored in advance in the ROM 20b. The ROM 20b uniquely indicates a predetermined correlation set in advance for each type of packet information generated in response to the output of the control command of the main control unit 10 and the program code for the CPU 20a to execute processing. An intermediate operation authentication expected value is stored in advance. Of the storage area of the ROM 20b, the storage area in which the intermediate operation authentication expected value is stored in advance can correspond to, for example, the expected value storage means 21 shown in FIG. The RAM 20c functions as a work area for calculations performed when the CPU 20a executes processing.

In the first embodiment, the processing relating to the authentication of the latter-stage unit 20 is as follows [1] to [4].
[1] Reception of Control Signal The effect control unit 203 adds control command data and accompanying data to operation authentication data that is not used for authentication by the effect control unit 203 among the control signals with authentication data transmitted from the main control unit 10. The control signal with operation authentication data is transmitted to the rear stage unit 20. When receiving the control signal with operation authentication data, the rear stage unit 20 performs the following processes [2] to [4]. When receiving a normal control signal consisting only of control command data and accompanying data, the subsequent stage unit 20 discards the received control command data and accompanying data without performing processing related to authentication.

[2] Extraction of synchronization code The post-stage unit 20 extracts operation authentication data from the control signal with operation authentication data. Next, the post-stage unit 20 extracts the synchronization code from the extracted operation authentication data, and can determine the operation sequence of the main control unit 10 such as the output order of the control commands in the operation test value memory which is a predetermined storage area of the RAM 20c. The synchronization code is stored in association with each other. When the main control unit 10 performs encryption processing on the synchronization code, the subsequent stage unit 20 performs decryption processing corresponding to the applied encryption processing on the extracted synchronization code.

  Here, in the first embodiment, for example, the operation test value memory of the RAM 10c used when generating the operation test value of the main control unit 10 and the RAM 20c used when extracting the operation test value of the rear stage unit 20 are described. The affiliation source of the memory, such as the operation test value memory, can be identified without confusion even if it is not specified. Therefore, unless otherwise specified, the same name is used regardless of the memory origin (in this example, “operation test value memory” is used). This also applies to the individual test value memory.

[3] Intermediate Operation Authentication The post-stage unit 20 performs intermediate operation authentication on the control command output of the main control unit 10 in the following order using a plurality of synchronization codes stored in the operation test value memory.
{1} Intermediate operation authentication using synchronization code
{1-1} The post-stage unit 20 reads a plurality of pieces of packet information from the plurality of synchronization codes stored in the operation inspection value memory in association with the order in which the control commands of the main control unit 10 are output.
{1-2} The post-stage unit 20 calculates the difference between the packet information generated at a certain timing among the plurality of read packet information and the packet information generated at a timing when a predetermined generation interval has elapsed from this packet information. Ask for. This difference is not limited to subtraction, but various arithmetic operations and logical operations can be considered.
{1-3} The post-stage unit 20 is shared with the main control unit 10 and is set in advance for each type of packet information. The information represents the correlation between packet information generated at successive generation timings. The stored intermediate operation authentication expected value is read from a predetermined storage area. The expected intermediate operation authentication value to be read is one indicating a continuous packet or one indicating an intermittent packet. In the first embodiment, an intermediate operation authentication expected value indicating continuous packet information is read.

{1-4} The latter stage unit 20 determines whether or not the information indicated by the difference value obtained in the process {1-2} matches the intermediate operation authentication expected value read in the process {1-3}. to decide.
The subsequent stage unit 20 determines that the operation authentication is successful when the information indicated by the difference value matches the operation authentication expected value. Further, when the information indicated by the difference value and the expected operation authentication value do not match, the rear stage unit 20 determines that the operation authentication has not been successful.
{1-5} When the information indicated by the difference value and the intermediate operation authentication expected value are the same, the subsequent stage unit 20 generates an intermediate operation authentication result indicating that both are the same, and the information indicated by the difference value and the intermediate value When the operation authentication expected values are not the same, the rear stage unit 20 generates an intermediate operation authentication result indicating that the both are not the same. In the first embodiment, in the main control unit 10, the type of packet information used for generating the synchronization code for the first time is continuous packet information, and the intermediate operation authentication expected value read by the subsequent unit 20 is a continuous packet. Since the information indicates information, the first intermediate operation authentication result in the processing related to the authentication of the rear stage unit 20 is generated so that the information indicated by the difference value and the intermediate operation authentication expected value are identical.

(Calculation example of intermediate operation authentication using synchronization code)
Hereinafter, a calculation example of the intermediate operation authentication using the synchronization code in the rear stage unit 20 will be described. The subsequent stage unit 20 obtains a correlation between two pieces of packet information generated at successive generation timings. For example, the basic value of the first packet (hereinafter referred to as “packet 1”) = 0x03, the basic value of the second packet (hereinafter referred to as “packet 2”) = 0x05, and the correlation condition between packet 1 and packet 2 Becomes “+2”. The post-stage unit 20 stores the correlation condition as an intermediate operation authentication expected value in advance. The synchronization code corresponding to packet 1 transmitted from the main control unit 10 is 0x03 as the basic value, and the synchronization code corresponding to packet 2 is packet 1 + packet 2, that is, 0x03 + 0x05, and "0x08" is transmitted.

  Then, the packet 1 received by the rear stage unit 20 is 0x03 as the basic value, and the packet 2 is 0x08. Then, in order to calculate the basic value of the packet 2, the packet 1 is subtracted from the received packet 2 to obtain 0x08-0x03 = 0x05.

  When the basic values of both packet 1 and packet 2 are obtained, the correlation between the two packets is obtained. That is, packet 2 basic value−packet 1 basic value = 0x05−0x03, and the difference value is 0x02. Since this value coincides with the correlation condition (which is +2) between the basic value of packet 1 and the basic value of packet 2 and can be determined to be the same as the intermediate operation authentication expected value, An intermediate operation authentication result indicating that they are the same is generated. Thereafter, the rear stage unit 20 erases the synchronization code stored in the operation test value memory of the RAM 20c.

  In the calculation of packet 1 and packet 2, the number of digits may be adjusted so that the calculation result does not overflow, or the basic values of packet 1 and packet 2 may be selected within a numerical range that does not overflow. Further, it may be calculated as an unsigned operation. Further, the correlation condition may be changed for each authentication process in order to increase the authentication strength. For example, the first correlation condition may be “+2”, the second correlation condition may be “+5”, the third correlation condition may be “+1”, and the like. However, when applying the correlation change rule as described above, the main control unit 10, the subsequent stage unit 20, and the effect control unit 203 share each other in advance or prepare means and processes for notification. Keep it.

  In addition, simply transmitting continuous packet information may cause a third party to analyze packet information differences. Accordingly, the basic value may be preprocessed to prevent analysis. For example, various arithmetic processing such as exclusive OR operation may be performed on the basic value of the packet information. In addition, the pre-processing to the basic value may be performed only on one of the two pieces of packet information generated at a predetermined generation timing for each arbitrary interval such as packet 1 and packet 2. , May be applied to both.

(Calculation example of intermediate operation authentication result generation)
An example of the calculation for generating the intermediate operation authentication result is shown below.
The rear-stage unit 20 generates 1-byte long random numbers (range “0x00” to “0xFF”) using uniform random numbers having the same appearance probability of all values. For example, assume that a random number “0x4B” is generated by a uniform random number. When generating the intermediate operation authentication result indicating that they are the same, the latter stage unit 20 intermediates the data “0x4B” in which the value of the least significant bit of the random number “0x4B” generated by the uniform random number is “1”. Generated as an operation authentication result. On the other hand, when generating the intermediate operation authentication result indicating that they are not identical, the latter stage unit 20 generates data “0x4A” in which the value of the least significant bit of the random number “0x4B” generated by the uniform random number is “0”. As an intermediate operation authentication result.

[4] Generation / Transmission of Intermediate Authentication Information Signal The post-stage unit 20 performs the same encryption process as when the main control unit 10 generates authentication data for the intermediate operation authentication result obtained by the process of [3]. To generate intermediate authentication information. The post-stage unit 20 generates an intermediate authentication information signal according to the content of the intermediate authentication information and transmits it to the effect control unit 203. Specifically, when the latter stage unit 20 generates an intermediate operation authentication result indicating that the information indicated by the difference value of the received packet information and the intermediate operation authentication expected value are the same in the process [3]. When an intermediate authentication information signal indicating that is generated and an intermediate operation authentication result indicating that the information indicated by the difference value of the received packet information and the intermediate operation authentication expected value are not the same is generated, An intermediate authentication information signal indicating is generated. Then, the post-stage unit 20 transmits the generated intermediate authentication information signal to the effect control unit 203 and deletes each data stored in the operation inspection value memory. The details of the processing related to the authentication of the latter-stage unit 20 (the processing [1] to [4]) will be described later. Further, the means for previously storing the intermediate operation authentication expected value and the means for executing the intermediate operation authentication can correspond to, for example, the expected value storage means 21 and the intermediate authentication means 22 shown in FIG.

<Production control unit>
The effect control unit 203 includes a CPU 203a, a ROM 203b, a RAM 203c, a VRAM 203d, and the like. The CPU 203a mainly controls the effect during the game, and executes the effect lottery and effect processing based on the control command transmitted from the main control unit 10 based on the program (program code) stored in advance in the ROM 203b. . The ROM 203b stores in advance a program code for the CPU 203a to execute a lottery and a processing of effects and past effect patterns, and also stores in advance in the ROM 10b constituting the main control unit 10. A plurality of individual authentication expected values obtained by performing a plurality of half-group operations using the same data as the predetermined program code to be divided are stored in advance. Among the storage areas of the ROM 203b, the storage area in which the plurality of individual authentication expected values are stored in advance can correspond to, for example, the expected value storage means 31 shown in FIG. The RAM 203c functions as a work area for data and the like in arithmetic processing performed when the CPU 203a executes lottery and presentation processing of effects and arithmetic processing performed when processing related to authentication is executed. Image data to be displayed on the symbol display unit 104 is written in the VRAM 203d.

When the effect control unit 203 receives a control command related to the effect transmitted from the main control unit 10, the effect control unit 203 performs a lottery based on the control command and finalizes effects such as an effect background pattern, a reach effect pattern, and an appearance character. At the same time, the determined effect is controlled.
In addition, the symbol display unit 104 is connected to the output side of the effect control unit 203, and, for example, a symbol change effect display is developed on the symbol display unit 104 according to the content determined by the lottery.

Normally, the CPU 203a reads a program stored in the ROM 203b, executes various image processing such as background image display processing, symbol image display and variation processing, and character image display processing. Write. The background image, the design image, and the character image are superimposed and displayed on the design display unit 104 on the display screen.
That is, the design image and the character image are displayed so as to be seen in front of the background image. At this time, if the background image and the design image overlap at the same position, the design image is preferentially stored in the VRAM 203d by referring to the Z value of the Z buffer of each image data by a known hidden surface removal method such as the Z buffer method. .

  In addition to the processing related to the effects outlined above, the effect control unit 203 receives the control signal with authentication data, based on the program stored in advance in the ROM 203b, [1] to [5] The processing related to authentication shown in FIG. A final authentication judgment is performed from both sides of the individual authentication and the operation authentication by the authentication processing of the effect control unit 203.

[1] Reception of control signal The production control unit 203 is configured such that the control signal transmitted from the main control unit 10 is a normal control signal including only control command data and accompanying data, or in addition to control command data and accompanying data. It is determined whether it is a control signal with authentication data to which authentication data including individual authentication data and operation authentication data is added. When the received control signal is a normal control signal, the effect control unit 203 performs the process related to the effect based on the control command data and the accompanying data, and ends the process related to authentication. On the other hand, when the received control signal is a control signal with authentication data, the effect control unit 203 executes the following processes [2] to [5] on the assumption that the process related to authentication is continued.

[2] Extraction of individual test value and operation authentication data The effect control unit 203 extracts individual authentication data and operation authentication data from the control signal with authentication data. Next, the effect control unit 203 performs a decryption process corresponding to the encryption process used when generating the individual authentication data on the extracted individual authentication data to extract an individual test value, and an individual that is a predetermined storage area of the RAM 203c. In addition to storing in the inspection value memory, the extracted operation authentication data is stored in the operation inspection value memory, which is a predetermined storage area of the RAM 203c. Next, the control command data and accompanying data are added to the operation authentication data in the operation inspection value memory to generate a control signal with operation authentication data, and the control signal with operation authentication data is transmitted to the subsequent stage unit 20. The effect control unit 203 extracts only the individual authentication data from the control signal with authentication data transmitted from the main control unit 10, and immediately after that, transmits other than the individual authentication data as the control signal with operation authentication data to the subsequent stage unit 20. May be.

[3] Individual authentication The effect control unit 203 performs the semi-group operation in the order shown below on all the individual test values stored in the individual test value memory, so that the individual of the main control unit 10 Perform authentication processing.
{1} The effect control unit 203 performs a half-group operation (hereinafter referred to as a combination process) using all the individual test values stored in the individual test value memory.
{2} The effect control unit 203 reads the stored individual authentication expected value from a predetermined storage area of the ROM 203b.

{3} The effect control unit 203 determines whether or not the calculation result in the process {1} (hereinafter referred to as the combination result) matches the individual authentication expectation value read in the process {2}.
The effect control unit 203 determines that the individual authentication is successful when the combined result matches the expected individual authentication value.
Since the semi-group operation satisfies the above-mentioned combination rule, it is a result obtained by performing the semi-group operation on all of the same data as the predetermined program code stored in advance in the ROM 10b of the main control unit 10. The expected individual authentication value matches the combined result obtained by performing the semigroup operation on the individual test values for the number of divisions generated from the predetermined program code. At this time, that is, when the individual authentication for the main control unit 10 is successful, the number of individual test values (hereinafter referred to as the number of connections) subjected to the combination process and the number of divisions naturally match. Thereby, the production control unit 203 authenticates the validity of the main control unit 10.
On the other hand, the effect control unit 203 determines that the individual authentication has not been successful when the combined result and the expected individual authentication value do not match.

When the individual authentication is successful in the process {4} {3}, the effect control unit 203 generates an individual authentication result indicating that the individual authentication is successful.
If the individual authentication is not successful in the process of {5} {3}, the effect control unit 203 determines whether or not the number of individual authentication data received from the main control unit 10 is a predetermined number or more. The predetermined number is an arbitrary number within the range not less than the current number of connections (number of divisions) and not more than the number (maximum number of divisions) in which the program code stored in the program code storage area 400 (see FIG. 4) can be divided. is there.
{5-1} If the number of received individual authentication data is less than the predetermined number, the production control unit 203 determines that the individual authentication is not yet possible and can replace the individual authentication result with, for example, authentication halfway data. Any value (for example, all 0 or all 1) having the same data length as the data length of the individual authentication result is generated.
{5-2} If the number of received individual authentication data is greater than or equal to the predetermined number, the effect control unit 203 determines that the individual authentication has not been successful, and displays an individual authentication result indicating that the individual authentication has not been successful. Generate.

(Calculation example of expected generation of individual authentication)
A method for generating the expected individual authentication value will be described with reference to FIG.
The effect control unit 203 holds, as an individual authentication expected value, a value obtained by performing a semi-group operation on the same data as the predetermined program code to be divided stored in the program code storage area 400. For example, the expected individual authentication value in the case of method A is “0x4E” which is the sum of “0x01” to “0x0C”. Further, the individual authentication expected value in the case of method B is “0x0C” which is an exclusive OR of “0x01” to “0x0C”. The effect control unit 203 holds the same number of individual authentication expected values as the number of half-group operations that are the individual test value generation method by the main control unit 10.

  For example, the individual authentication expected value may be stored in advance in a predetermined storage area of the ROM 203b that configures the effect control unit 203 at the time of manufacture or the like, but is not limited thereto, and is transmitted from another component to the effect control unit 203. It is good to do. Examples of the other components include a prize ball control unit 204 and a dedicated processing unit for generating an individual authentication expected value (hereinafter referred to as an individual authentication expected value calculation unit). Note that the individual authentication expected value calculation unit may transmit the stored individual authentication expected value to the effect control unit 203. In addition, a coefficient necessary for calculating the individual authentication expected value may be transmitted from an external device to the effect control unit 203 and the individual authentication expected value calculation unit via an external connection interface (not shown). In this manner, if the individual authentication expected value is not stored in advance in the predetermined storage area of the ROM 203b that constitutes the effect control unit 203 and is acquired from another component, the individual test value is subsequently changed. It becomes possible to do. This also applies to the intermediate operation authentication expected value and the operation authentication expected value.

[4] Reception of Intermediate Authentication Information Signal, Extraction of Intermediate Operation Authentication Result The production control unit 203 performs intermediate authentication information in the subsequent stage unit 20 on the intermediate authentication information indicated by the intermediate authentication information signal transmitted from the subsequent stage unit 20. The decryption method corresponding to the encryption method used at the time of generating is performed, and the intermediate operation authentication result is extracted. Next, the effect control unit 203 stores the extracted intermediate motion authentication result in the motion inspection value memory, which is a predetermined storage area of the RAM 203c, and confirms the result of the intermediate motion authentication in the rear stage unit 20. In addition, the production control unit 203 suspends the following processing related to authentication until an intermediate authentication information signal is received.

[5] Action Authentication The effect control unit 203 determines the intermediate action authentication result stored in the action test value memory and the number of individual test values that are targets of the combination process when the individual authentication is successful (the number of connections). ) Is used to authenticate the operation of the pachinko gaming machine 1 in the order shown below. The effect control unit 203 specifies the number of connections prior to operation authentication.

{1} Operation authentication using the intermediate operation authentication result by synchronization code
{1-1} The effect control unit 203 reads the intermediate motion authentication result stored in the motion test value memory. In the first embodiment, in the first operation authentication, an intermediate operation authentication result indicating that the information indicated by the difference value of the packet information and the intermediate operation authentication expected value are the same is read.
{1-2} The effect control unit 203 reads the expected operation authentication value used for the current operation authentication from the predetermined storage area of the ROM 203b. The expected operation authentication value is the information indicated by the difference value between the packet information corresponding to the type of packet information recognized as being generated by the main control unit 10 in the process related to the authentication, and the expected intermediate operation authentication value. Are pre-stored in the effect control unit 203 as information indicating whether or not they are the same. In the first embodiment, the expected operation authentication value read for the first time is set in advance as information indicating the same.

{1-3} The production control unit 203 determines whether or not the intermediate operation authentication result read out in the process of {1-1} matches the operation authentication expected value read out in the process of {1-2}. to decide.
{1-4} The production control unit 203 determines that the operation authentication is successful when the intermediate operation authentication result and the operation authentication expected value match, and when the intermediate operation authentication result and the operation authentication expected value do not match, Judge that the operation authentication was not successful. In the first embodiment, the initial intermediate operation authentication result transmitted from the rear stage unit 20 indicates the same, and the initial operation authentication expected value read by the effect control unit 203 indicates the same. Since it is information, it is determined that the operation authentication is successful.

    When the operation authentication is successful in the processing of {1-5} {1-4}, the effect control unit 203 generates an operation authentication result indicating that the operation authentication is successful and is stored in the operation inspection value memory. Erase all existing data. Then, the effect control unit 203 determines whether or not to change the type of expected operation authentication value to be read next time in accordance with a predetermined agreement based on the number of connections found in the process [3]-{3}. The predetermined agreement is the same as that in which the main control unit 10 selects the type of packet information used for generating the synchronization code. In other words, the type of expected operation authentication value is changed when the number of connections is odd, and the type of expected operation authentication value currently used is continued when the number of connections is even. If the operation authentication is not successful in the process {1-4}, the effect control unit 203 generates an operation authentication result indicating that the operation authentication is not successful.

[6] Processing Based on Authentication Result The effect control unit 203 uses the individual authentication result obtained by the individual authentication that is the processing of [3] and the operation authentication result obtained by the operation authentication that is the processing of [5]. The authenticity of the pachinko gaming machine 1 is authenticated from both the individual authentication and the operation authentication, and a final authentication judgment is made. If both the individual authentication result obtained by the individual authentication that is the process of [3] and the operation authentication result obtained by the operation authentication that is the process of [5] are results indicating successful authentication, The control unit 203 determines that the normality of the pachinko gaming machine 1 has been successfully authenticated. Then, the effect control unit 203 executes processing based on the control command data and accompanying data included in the control signal with authentication data transmitted from the main control unit 10, and also includes an individual test value memory and an operation test value memory. Each data stored in is deleted, and the process related to authentication is terminated.
On the other hand, either the individual authentication result obtained by the individual authentication that is the process [3] or the operation authentication result obtained by the operation authentication that is the process [5] was a result indicating that authentication was unsuccessful. In this case, it is determined that the normality of the pachinko gaming machine 1 has not been successfully authenticated. Then, the effect control unit 203 interrupts the processing based on the control command data and the accompanying data, discards the data, performs processing such as notifying that an illegal act has been detected, and the individual test value memory and operation Each data stored in the inspection value memory is erased, and the process related to authentication is terminated.

A chance button detection unit 220 that detects that the chance button 117 is operated is connected to the input side of the effect control unit 203. In addition, a speaker 277 is connected to the output side of the effect control unit 203 so that sound is output as determined by the effect control unit 203.
A lamp control unit 205 is provided on the output side of the effect control unit 203.

<Other control units>
The lamp control unit 205 operates the program read from the ROM 205b based on the control command transmitted from the effect control unit 203 to execute the effect process, the ROM 205b that stores the program and various effect pattern data, and the CPU 205a. A RAM 205c and the like functioning as a data work area at the time of arithmetic processing are provided. The lamp control unit 205 controls the lamp 262, the effect lights 111a and 111b, and the effect agent actuating device 254. The stage effect actuating device 254 is configured by a motor, a solenoid, and the like that actuate a stage role such as the stage role 115.

The lamp control unit 205 performs lighting control and the like for various lamps 262 provided on the game board 101 and underframe, etc., and performs lighting control and the like for the plurality of lights 112 that respectively constitute the effect lights 111a and 111b. In order to change the irradiation direction of the light from each light 112, drive control for the motor is performed.
Further, the lamp control unit 205 is based on the control command transmitted from the effect control unit 203, and the effect agent actuating device 254 that operates the solenoid of the effect agent actuating device 254 that operates the effect agent 115 and the collar unit 116. Drive control for the motor is performed.

  The prize ball control unit 204 is connected to the main control unit 10 so as to be able to transmit and receive. The prize ball control unit 204 performs prize ball control based on a program stored in the ROM 204b. The prize ball control unit 204 includes a CPU 204a that executes a prize ball control process by operating a program stored in the ROM 204b, and a RAM 204c that functions as a data work area during the calculation process of the CPU 204a.

The winning ball control unit 204 makes each of the winning ports (first starting port 105, second starting port 120, normal winning port 107, first big winning port 109c, second big winning a prize) to the payout unit 291 connected thereto. Control is performed to pay out the number of prize balls corresponding to the game ball that has entered the mouth 129c). The award ball control unit 204 detects an operation of launching a game ball with respect to the launch unit 292 and controls the launch of the game ball. The launching unit 292 launches a game ball for gaming, and includes a sensor (not shown) that detects a game operation by the player, a solenoid that launches the game ball, and the like (not shown). When the award ball control unit 204 detects a game operation by the sensor of the launch unit 292, the prize ball control unit 204 intermittently fires a game ball by driving a solenoid or the like in response to the detected game operation, thereby playing the game area 103 of the game board 101. A game ball is sent out.
The payout unit 291 includes a motor for paying out a predetermined number from the game ball storage unit.

  The main control unit 10, the rear stage unit 20, the production control unit 203, the prize ball control unit 204, and the lamp control unit 205 having the above-described configuration are respectively different printed boards (for example, the main control unit 10 is a main control board, The rear stage unit 20 is mounted on an intermediate board, the effect control unit 203 is mounted on an effect control board, the prize ball control unit 204 is installed on a prize ball control board, and the lamp control unit 205 is installed on a lamp control board. Among these, “peripheral board” is used as a general term for the intermediate board, the effect control board, the prize ball control board, and the lamp control board. For example, the rear stage unit 20 can be mounted on the same printed circuit board as the effect control unit 203. The prize ball control unit 204 can also be mounted on the same printed circuit board as the main control unit 10.

  Next, the operation of the pachinko gaming machine 1 configured as described above will be described with reference to the drawings. In the following description, “transmit a control command” means “transmit a control signal including data indicating the control command (control command data)”. For example, the individual authentication shown in FIG. The presence of data, operation authentication data, and accompanying data is not considered.

Processing including control command transmission by the main control unit 10 to the effect control unit 203 and the prize ball control unit 204 will be described with reference to the flowcharts shown in FIGS.
First, the main control unit 10 executes an initial setting process associated with power-on of the pachinko gaming machine 1 (step S1), and then proceeds to step S2. When the pachinko gaming machine 1 is turned on, the peripheral board starts up and performs initialization of the RAM area in order to reliably capture the control command received from the main control board by the peripheral board. After that, the main control board is configured to stand up. For example, the main control unit 10 sets a predetermined value in the stack pointer as an initial setting process, and waits for the rear stage unit 20, the production control unit 203, and the prize ball control unit 204 to enter a standby state. And wait for a predetermined time (for example, about 1 second).

  In step S2, the main control unit 10 transmits a power-on command to the effect control unit 203 and the prize ball control unit 204, and then proceeds to step S3. When the power-on command is received, the effect control unit 203 controls the design display command at the time of power-on to each of the symbol display unit 104 and the lamp control unit 205, specifically, the customer in the non-game state of the gaming machine. A customer waiting demo command for displaying a waiting demo screen or a control command for lighting a lamp or the like is transmitted.

  The power-on command indicates a control command for executing processing associated with power-on after power-on. After each control board is started up, the main control unit 10 performs an effect control unit 203, a prize ball control unit 204, and Control commands transmitted to the rear stage unit 20 and the lamp control unit 205 via the effect control unit 203, and initial control information for controlling the game at the start-up after the power is turned on, for example, control mode, backup data, etc. Or a control command for controlling the initial effect display, for example, a control command for starting various demonstration displays such as a customer waiting demonstration. The power-on command also includes a control command for transmitting the control mode, backup data, etc., which is executed when the reset button of the gaming machine is pressed.

  In step S <b> 3, the main control unit 10 determines whether or not the number of undrawn winning prizes is 0 with reference to the data for undrawn winning prizes stored in the RAM 10 c. Here, the number of undrawn winning prizes is a lottery corresponding to the number of winning game balls based on the number of game balls (number of winning prizes) detected by the first start port detecting unit 221 or the second start port detecting unit 225. This is the number obtained by subtracting the number of times performed (number of already drawn lots). If the determination result in step S3 is “NO”, that is, if the number of undrawn winning prizes is not zero, the main control unit 10 proceeds to step S10 described later. On the other hand, when the determination result of step S3 is “YES”, that is, when the number of undrawn winning prizes is 0, the main control unit 10 proceeds to step S4.

  In step S4, the main control unit 10 measures the time that has elapsed since the start-up demonstration was started, and then proceeds to step S5. In step S <b> 5, the main control unit 10 determines whether or not a predetermined time has elapsed since the start-up demonstration was started. If the determination result in step S5 is “YES”, that is, if a predetermined time has elapsed since the demonstration at power-on was started, the main control unit 10 proceeds to step S6. Note that the control command for starting the demonstration when the power is turned on may be a customer waiting demonstration command.

  In step S6, the main control unit 10 transmits a customer waiting demonstration command to the effect control unit 203, and then proceeds to step S7. When receiving the customer waiting demonstration command, the effect control unit 203 transmits a control signal for the customer waiting demonstration to each of the symbol display unit 104 and the lamp control unit 205.

  On the other hand, if the determination result in step S5 is “NO”, that is, if a predetermined time has not elapsed since the start of the power-on demonstration (or the customer waiting demo), the main control unit 10 Proceed to S7. In step S <b> 7, the main control unit 10 detects whether or not the first start port detection unit 221 detects that a game ball has entered the first start port 105, or the second start port detection unit 225 detects that the second start port 120 has entered the second start port 120. It is determined whether or not a game ball is detected. If the determination result in step S7 is “YES”, that is, whether the first start port detection unit 221 detects that a game ball has entered the first start port 105 or the second start port detection unit 225 performs the second start. If a game ball has entered the mouth 120, the main control unit proceeds to step S8.

  On the other hand, if the determination result in step S7 is “NO”, that is, the first start port detector 221 does not detect the entry of a game ball into the first start port 105, and the second start port detector 225 In the case where the game ball has not entered the second start port 120, the main control unit returns to step S4 and repeats the processing after step S4.

  In step S8, the main control unit 10 clears the time that has been measured since the start of the customer waiting demo (or demo at power-on), and then proceeds to step S9. In step S9, the main control unit 10 adds 1 to the number of undrawn winning prizes. If the first start port detection unit 221 or the second start port detection unit 225 detects a plurality of game balls entering, the main control unit 10 enters the number of undrawn winnings in this step S9. Add the corresponding numbers. Then, the main control unit 10 proceeds to step S10. In step S10, the main control unit 10 randomly acquires one jackpot determination random number from a random number counter (for example, counts 0 to 250) prepared in advance, and then proceeds to step S11. In step S11, the main control unit 10 subtracts 1 from the number of undrawn winning prizes, and then proceeds to step S12.

  In step S12, for example, the main control unit 10 refers to the jackpot determination data table stored in advance in the ROM 10b, and the jackpot determination random number acquired in the process of step S10 is stored in the jackpot determination data table. It is determined whether or not the jackpot random value. In step S12, the main control unit 10 refers to the jackpot determination data table, for example, when the acquired big hit determination random number is an out-of-range random number, and further “reach with reach” or “without reach”. It is also judged whether it is “out of”. If the determination result in step S12 is “YES”, that is, if the jackpot determination random number acquired in step S10 is a predetermined jackpot random number, the main control unit 10 proceeds to step S13.

  In step S13, the main control unit 10 includes, for example, control data (accompanying data) such as a jackpot type code (whether it is a normal hit or per probability fluctuation), reach, symbol variation time, etc. in the effect control unit 203. After transmitting the jackpot reach command (design variation command), the process proceeds to step S14. In step S14, the main control unit 10 determines whether or not the symbol variation time has elapsed. If the determination result in step S14 is “NO”, that is, if the symbol variation time has not elapsed, the main control unit 10 repeats the same determination. When the symbol variation time has elapsed, the determination result in step S14 is “YES”, and the main control unit 10 proceeds to step S15.

  In step S15, the main control unit 10 transmits a symbol stop command to the effect control unit 203, and then proceeds to step S16. In step S16, the main control unit 10 transmits a jackpot start command to the effect control unit 203, and then proceeds to step S17. In step S17, the main control unit 10 sequentially transmits to the effect control unit 203 commands corresponding to each of the big hits (big hit command), and after completing the transmission of the big hit command for all the rounds, proceeds to step S18. . In step S18, the main control unit 10 transmits a jackpot end command to the effect control unit 203, and then proceeds to step S22.

  On the other hand, if the determination result in step S12 is “NO”, that is, if the jackpot determination random number obtained in the process of step S10 is not a predetermined jackpot random number, the main control unit 10 proceeds to step S19. In step S19, the main control unit 10 determines that the “reach with a reach” command is “out-of-reach reach command (design variation command)”, and the “out-of-reach command” indicates a “removal command (design variation command)”. Is transmitted to the effect control unit 203, and then the process proceeds to step S20.

  In step S20, the main control unit 10 determines whether or not the symbol variation time has elapsed. When the determination result of step S20 is “NO”, that is, when the symbol variation time has not elapsed, the main control unit 10 repeats the same determination. When the symbol variation time has elapsed, the determination result in step S20 is “YES”, and the main control unit 10 proceeds to step S21. In step S21, the main control unit 10 transmits a symbol stop command to the effect control unit 203, and then proceeds to step S22.

  In step S22, the main control unit 10 determines whether or not the power of the pachinko gaming machine 1 has been turned off. If the determination result in step S22 is “NO”, that is, if the power of the pachinko gaming machine 1 is not turned off, the main control unit 10 returns to step S3 shown in FIG. repeat.

  On the other hand, when the determination result of step S22 is “YES”, that is, when the power of the pachinko gaming machine 1 is turned off, the main control unit 10 proceeds to step S23. In step S <b> 23, the main control unit 10 transmits an end process command to the effect control unit 203 and then ends a series of processes.

  Here, FIG. 8 shows a timing chart as an example of the transmission timing of the jackpot related command (the jackpot reach command, jackpot start command, jackpot command, jackpot end command). The jackpot reach command shown in FIG. 8 (1) is transmitted at random. The jackpot start command shown in FIG. 8 (2) is transmitted only once when shifting to the jackpot state when a jackpot has actually occurred. Further, the jackpot command shown in FIG. 8 (3) is continuously transmitted for each round after shifting to the jackpot state. Also, the jackpot end command shown in FIG. 8 (4) is transmitted only once when all rounds of the jackpot state are completed and the state transitions to the normal state.

  Next, processing by the effect control unit 203 will be described. In the following, processing of the effect control unit 203 at the time of symbol variation (when a jackpot reach command (see step S13 shown in FIG. 7) or a loss reach command (see step S19 shown in FIG. 7) is received) and a jackpot reach command is received. explain.

First, the symbol variation process by the effect control unit 203 will be described with reference to the flowchart shown in FIG.
The effect control unit 203 has received from the main control unit 10 either a jackpot reach command (see step S13 shown in FIG. 7) or an outlier reach command (see step S19 shown in FIG. 7) which is a symbol variation command. (See step S31 in FIG. 9). When the determination result is “NO”, the effect control unit 203 repeats the determination. Then, when either the jackpot reach command or the miss reach command is received, the determination result in step S31 is “YES”, and the effect control unit 203 proceeds to step S32.

  In step S32, the effect control unit 203 randomly acquires one random effect selection random number from random numbers (for example, 0 to 250) prepared in advance, and then proceeds to step S33. In step S33, the effect control unit 203 selects a variation effect type based on the variable effect selection random number acquired in the process of step S32, and then proceeds to step S34.

  In step S34, the effect control unit 203 transmits an effect start command for each variable effect to the symbol display unit 104 and the lamp control unit 205, and then proceeds to step S35. In step S35, the effect control unit 203 determines whether or not the effect time of the variable effect has elapsed. If the determination result in step S35 is “NO”, that is, if the effect time of the changing effect has not elapsed, the effect control unit 203 proceeds to step S36.

  In step S36, the effect control unit 203 determines whether or not a symbol stop command (see steps S15 and S21 shown in FIG. 7) has been received from the main control unit 10. If the determination result in step S36 is “NO”, that is, if the symbol stop command has not been received, the effect control unit 203 returns to step S35 and repeats the processing after step S35.

  On the other hand, if the determination result in step S36 is “YES”, that is, if a symbol stop command is received, the effect control unit 203 proceeds to step S37. In addition, when the determination result in step S35 is “YES”, that is, when the effect time of the variable effect has elapsed, the effect control unit 203 proceeds to step S37. In step S37, the effect control unit 203 transmits an effect stop command to the symbol display unit 104 and the lamp control unit 205, and then ends the series of processes.

Next, the process at the time of the big hit by the production | presentation control part 203 is demonstrated with reference to the flowchart shown in FIG.
First, the effect control unit 203 determines whether or not a jackpot start command (see step S16 shown in FIG. 7) is received from the main control unit 10 (see step S41 in FIG. 10). When the determination result is “NO”, the effect control unit 203 repeats the determination. When the jackpot start command is received, the determination result in step S41 is “YES”, and the effect control unit 203 proceeds to step S42.

  In step S42, the effect control unit 203 transmits a jackpot start processing command to the symbol display unit 104 and the lamp control unit 205, and then proceeds to step S43. In step S43, the effect control unit 203 determines whether or not a round-by-round jackpot command (see step S17 shown in FIG. 7) has been received from the main control unit 10. When the determination result is “NO”, the effect control unit 203 repeats the determination. And if the jackpot command according to round is received, the judgment result of step S43 will be "YES", and the production | presentation control part 203 will progress to step S44.

  In step S44, the effect control unit 203 transmits to the symbol display unit 104 or the lamp control unit 205 a round-by-round processing command corresponding to the received round-by-round jackpot command, and then proceeds to step S45. In step S45, it is determined whether or not a jackpot end command (see step S18 shown in FIG. 7) has been received from the main control unit 10. When the determination result is “NO”, the effect control unit 203 repeats the determination. When the jackpot end command is received, the determination result in step S45 is “YES”, and the effect control unit 203 proceeds to step S46. In step S46, the effect control unit 203 transmits the received jackpot end command to the symbol display unit 104 and the lamp control unit 205, and then ends the series of processes.

Next, lamp control processing by the lamp control unit 205 will be described. Here, processing when a symbol variation command is received from the effect control unit 203 (during symbol variation) will be described with reference to the flowchart shown in FIG.
First, the lamp control unit 205 determines whether or not an effect start command (see step S34 shown in FIG. 9) has been received from the effect control unit 203 (see step S51 in FIG. 11). When the determination result is “NO”, the lamp control unit 205 repeats the determination. Then, when an effect start command is received, the determination result in step S51 is “YES”, and the lamp control unit 205 proceeds to step S52.

  In step S52, the lamp control unit 205 reads, for example, data stored in advance for each command from the ROM 205b, and then proceeds to step S53. In step S53, the lamp control unit 205 executes a selection routine for each command, and then proceeds to step S54. In step S54, the lamp control unit 205 sets the lamp data, and then proceeds to step S55.

  In step S55, the lamp control unit 205 outputs the lamp data to the lamp 262, and then proceeds to step S56. Accordingly, the lamp 262 is turned on or off based on the lamp data output from the lamp control unit 205. In step S56, the lamp control unit 205 determines whether or not an effect stop command (see step S37 shown in FIG. 9) is received from the effect control unit 203. When the determination result is “NO”, the lamp control unit 205 returns to Step S55 and repeats the processes after Step S55. On the other hand, if the determination result in step S56 is “YES”, that is, if an effect stop command is received from the effect control unit 203, the lamp control unit 205 proceeds to step S57. In step S57, the lamp control unit 205 ends the series of processes after stopping the output of the lamp data.

  As described above, the effect control unit 203 and the lamp control unit 205 perform various processes based on the control command transmitted from the main control unit 10. The same applies to the prize ball control unit 204. Hereinafter, “peripheral part” is used as a generic term for the effect control unit 203, the prize ball control unit 204, and the lamp control unit 205. Accordingly, the peripheral portion 30 of the pachinko gaming machine 1 according to the first embodiment shown in FIG. 1 includes an effect control means having the function of the effect control section 203, a prize ball control means having the function of the prize ball control section 204, and a lamp. Lamp control means having the function of the control unit 205 is provided.

By the way, as described above, gaming media are paid out regardless of the game due to fraudulent acts performed on the gaming machine or malfunction of the gaming machine due to noise or the like, and the gaming store suffers a great deal of damage. There is. Therefore, in order to prevent malfunctions of the gaming machine due to the above-mentioned fraudulent acts and noise, the pachinko gaming machine 1 according to the present embodiment 1 is provided with the rear stage unit 20 at the rear stage of the effect control unit 203.
In the first embodiment, the main control unit 10 generates individual authentication data for the number of divisions using a predetermined program code, and generates operation authentication data. These individual authentication data and operation authentication data Is added to the control command and transmitted to the post-stage unit 20 or the effect control unit 203.

  The post-stage unit 20 performs intermediate operation authentication using each operation inspection value (synchronization code) from the operation authentication data, and effects control is performed on the intermediate authentication information obtained by performing encryption processing on the obtained intermediate operation authentication result. To the unit 203. Then, the production control unit 203 performs the operation authentication using the intermediate operation authentication result obtained from the intermediate authentication information received from the subsequent stage unit 20 and performs the individual authentication using the individual authentication data to obtain the final authentication result. obtain. In this way, authentication processing is performed with the latter stage unit 20 and the production control unit 203 as the authenticator and the main control unit 10 as the person to be authenticated, and the normality of the pachinko gaming machine 1 is authenticated. By this authentication process, the fraudulent act can be detected and fraud to the pachinko gaming machine 1 can be prevented, and the pachinko gaming machine 1 caused by electrical noise or mechanical vibration applied from the outside can be prevented. Malfunctions can be reduced.

  Hereinafter, the process regarding the authentication performed between the main control part 10, the back | latter stage part 20, and the production | presentation control part 203 is demonstrated. Hereinafter, processing related to authentication between the main control unit 10 and the effect control unit 203 will be described with reference to the flowcharts shown in FIGS. 12 and 13, but between the main control unit 10 and the prize ball control unit 204. Processing related to authentication is performed in the same procedure.

  FIG. 12 is a flowchart illustrating an example of a processing procedure related to authentication by the main control unit 10. The main control unit 10 determines whether it is the transmission timing of the authentication data while transmitting a normal control signal (step S61) (step S62). If the determination result is NO, the main control unit 10 returns to step S61 and performs the determination in step S62 again. When the authentication data transmission timing comes, that is, when the output control command becomes a predetermined control command, the determination result in step S62 is “YES”, and the main control unit 10 proceeds to step S63 to determine the number of divisions. The method for determining the number of divisions is arbitrary. The number of divisions may be determined before the transmission timing of authentication data.

  Next, the main control unit 10 divides a predetermined program code by the determined number of divisions, performs a semi-group operation on each of the divided data, and calculates an individual test value (step S64). The value is subjected to encryption processing to generate individual authentication data (step S65). By this processing, individual test values and individual authentication data corresponding to the number of divisions are generated. The individual test value may be generated before the authentication data transmission timing comes.

  Next, the main control unit 10 selects the type of packet information used to generate the synchronization code, and generates a synchronization code based on the selected packet information (step S66). Specifically, it is packet information of either intermittent packet information or continuous packet information, and is determined at the time of the process related to the previous authentication. Note that the first time is determined in advance between the rear stage unit 20 and the effect control unit 203. Then, the main control unit 10 performs an encryption process on the generated synchronization code and generates operation authentication data (step S67).

  Subsequently, the main control unit 10 adds the individual test value (individual authentication data) and the synchronization code (operation authentication data) to the control command data, and transmits a control signal with authentication data to the effect control unit 203 (step S68). ). The control signal with authentication data may be transmitted continuously, or may be mixed with a normal control signal and transmitted. The main control unit 10 returns to step S68 and repeats transmission of the control signal with authentication data until all authentication data (individual authentication data and operation authentication data) is transmitted (step S69: NO). When there is untransmitted authentication data among the generated authentication data (step S69: NO), the main control unit 10 does not newly generate authentication data, and always returns to step S68 to transmit a control signal with authentication data. I do. Further, the control command for adding the authentication data is not particularly limited and may be an arbitrary control command. When all the authentication data is transmitted (step S69: YES), the process proceeds to step S70.

  Subsequently, the main control unit 10 determines whether or not the number of divisions determined in step S63 is a predetermined value (step S70). The predetermined value is an odd number in the first embodiment. When the number of divisions is a predetermined value (step S70: YES), the main control unit 10 changes the type of packet information used for generating the synchronization code during the next authentication process (step S71), The process ends. On the other hand, if the number of divisions is not a predetermined value (step S70: NO), the series of processing is terminated as it is without changing the type of packet information used for generation of the synchronization code in the next authentication processing.

  Next, processing related to authentication by the latter stage unit 20 will be described. FIG. 13 is a flowchart illustrating an example of a processing procedure related to authentication by the latter-stage unit 20. First, the rear stage unit 20 determines whether or not a control signal as shown in FIG. 5 transmitted from the main control unit 10 via the effect control unit 203 has been received (step S81). When the determination result is “NO”, the rear stage unit 20 repeats the same determination. And if the control signal transmitted via the production | generation control part 203 is received from the main control part 10 (step S81: YES), the back | latter stage part 20 will progress to step S82.

  In step S82, the post-stage unit 20 determines whether or not operation authentication data is included in the received control signal. If the operation control data is included in the received control signal (step S82: YES), the rear stage unit 20 proceeds to step S83. Here, the determination of whether or not the operation authentication data is included in the control signal is, for example, whether or not the data amount of the control signal is larger than that of the normal control signal, This is done by determining whether or not any bit constituting ID or identification data (not shown) provided separately indicates that each authentication data is included. In the process of step S82, the post-stage unit 20 does not determine whether or not the operation authentication data is included in the received control signal, but the control command data included in the control signal is a control of a predetermined control command. It may be determined whether it is command data.

  If the received control signal includes operation authentication data (step S82: YES), that is, if the received control signal is a control signal with operation authentication data, the rear stage unit 20 receives the received control signal with operation authentication data. The operation authentication data contained in is extracted and decrypted to extract the synchronization code (step S83). The rear stage unit 20 stores the extracted synchronization code in the operation inspection value memory, and proceeds to step S84.

  Subsequently, the post-stage unit 20 calculates the difference between the packet information included in the acquired synchronization code as the intermediate operation authentication using the synchronization code, and confirms the correlation of the packet information indicated by the obtained difference value (step). S84). Then, the post-stage unit 20 compares the correlation of the packet information indicated by the difference value confirmed in step S84 with the correlation condition (intermediate operation authentication expected value) held in advance as an expected value, and whether both are the same. Whether or not is checked (step S85). When both are the same (step S85: YES), the rear stage unit 20 generates an intermediate operation authentication result indicating the same (step S86), and proceeds to step S88. On the other hand, when both are not the same (step S85: NO), the latter stage part 20 produces | generates the intermediate | middle operation | movement authentication result which shows nonidentity (step S87), and progresses to step S88. Note that if the packet information included in the extracted synchronization code is one, the post-stage unit 20 returns to step S81 without performing the process of step S84, and repeats the subsequent processes until a plurality of pieces of packet information are acquired.

  Subsequently, the subsequent stage unit 20 performs encryption processing on the generated intermediate operation authentication result indicating either the same or non-identical, and generates intermediate authentication information indicating either the same or non-identical (step S88). Thereafter, the rear stage unit 20 generates an intermediate authentication information signal indicating the content of the generated intermediate authentication information, and transmits it to the effect control unit 203 (step S89). Then, the post-stage unit 20 deletes the data stored in the operation test value memory and discards the received control command data and accompanying data (step S90), and then ends the series of processes.

  Further, if the operation authentication data is not included in the received control signal in step S82, that is, if the received control signal is a normal control signal (step S82: NO), the rear stage unit 20 performs the authentication process. The received control command data and accompanying data are discarded (step S90), and the series of processes is terminated.

  Next, processing related to authentication by the effect control unit 203 will be described. FIG. 14 is a flowchart illustrating an example of a procedure of processing related to authentication by the effect control unit 203. First, the effect control unit 203 determines whether or not a control signal has been received from the main control unit 10 (step S101). When the determination result is “NO”, the effect control unit 203 repeats the determination. And if a control signal is received from the main control part 10, the judgment result of step S101 will be "YES", and the production | presentation control part 203 will progress to step S102.

  In step S102, the effect control unit 203 determines whether each authentication data is included in the received control signal. If the determination result in step S102 is “YES”, that is, if each authentication data is included in the received control signal, the effect control unit 203 proceeds to step S103. Here, the determination of whether or not each authentication data is included in the control signal is, for example, whether or not the data amount of the control signal is larger than that of the normal control signal, It is determined whether or not any bit constituting the ID or separately provided identification data (not shown) indicates that each authentication data is included, or a control command included in the control signal It may be determined whether the data is control command data of a predetermined control command set in advance for performing the authentication process.

  When each authentication data is included in the received control signal (step S102: YES), that is, when the received control signal is a control signal with authentication data, the effect control unit 203 adds the control signal with authentication data to the received control signal. The individual authentication data and the operation authentication data included are extracted, and the individual authentication data are further decrypted to extract the individual inspection value (step S103). The effect control unit 203 stores the extracted individual test value in the individual test value memory and the extracted operation authentication data in the operation test value memory, and proceeds to step S104. In step S102, if the received control signal does not include authentication data, that is, if the received control signal is a normal control signal (step S102: NO), the effect control unit 203 performs the authentication process. It progresses to step S115 without performing. Next, the production control unit 203 generates a control signal with motion authentication data by adding control command data and accompanying data to the motion authentication data stored in the motion inspection value memory, and outputs the control signal with motion authentication data to the subsequent stage. It transmits to the part 20 (step S104), and progresses to step S105.

  In step S105, the effect control unit 203 performs a semi-group operation (joining process) on all the individual test values in the individual test value memory as the individual authentication process (step S105). If there is one test value in the individual test value memory, the process directly proceeds to step S106 without performing the combining process. Then, the production control unit 203 collates the calculation result (combination result) of the combination process with the held individual authentication expected value, and determines whether or not the combined result and the individual authentication expected value match ( Step S106). If the combined result matches the expected individual authentication value (step S106: YES), the effect control unit 203 determines that the individual authentication of the main control unit 10 has succeeded (step S107).

  Next, the effect control unit 203 determines whether or not the intermediate authentication information signal transmitted from the subsequent unit 20 has been received (step S108), and repeats the same determination until it is received. When the intermediate authentication information signal transmitted from the rear stage unit 20 is received (step S108: YES), the effect control unit 203 extracts the intermediate operation authentication result in the rear stage unit 20 indicated by the intermediate authentication information signal, and for the motion test value Store in memory. Thereafter, the effect control unit 203 refers to the acquired intermediate operation authentication result stored in the operation inspection value memory as the operation authentication process, and transmits the intermediate operation authentication result in the rear stage unit 20 from the main control unit 10. Whether the correlation between the received packet information and the correlation condition (intermediate operation authentication expected value) previously stored as an expected value in the subsequent stage unit 20 indicates the same or non-identical (step S109) ).

  Subsequently, the effect control unit 203 reads the operation authentication expected value previously held as the expected value, and collates whether or not the intermediate operation authentication result matches the operation authentication expected value (step S110). When the intermediate operation authentication result matches the operation authentication expected value (step S110: YES), the effect control unit 203 has succeeded in the operation authentication of the main control unit 10 and the subsequent unit 20 (step S111), and in step S107. In addition to the individual authentication result, it is determined that the current authentication process of the pachinko gaming machine 1 was successful (step S112), and the process proceeds to step S113. On the other hand, if the intermediate operation authentication result and the operation authentication expected value do not match (step S110: NO), the production control unit 203 has not succeeded in the operation authentication of the main control unit 10 and the subsequent stage unit 20, and this pachinko game It is determined that the authentication process of the machine 1 was unsuccessful (step S117), and the process proceeds to step S118.

  Subsequently, the effect control unit 203 determines whether or not the number of connections determined in step S105 is a predetermined value (step S113). The predetermined value is an odd number like the main control unit 10. When the number of connections is a predetermined value (step S113: YES), the effect control unit 203 changes the type of expected operation authentication value used for the next operation authentication (step S114), and proceeds to step S115. On the other hand, if the number of connections is not a predetermined value (step S113: NO), the type of operation authentication expected value used at the time of the next operation authentication is not changed, and the process proceeds to step S115. In step S115, the data stored in the individual test value memory and the motion test value memory are erased and the process based on the control command data and the accompanying data is performed, and then the series of processes is terminated.

  On the other hand, when the combined result and the individual authentication expected value do not match in step S106 (step S106: NO), the effect control unit 203 receives the predetermined number or more of individual authentication data (step S116: NO), step S101. Returning to the above, the process of receiving the individual authentication data and combining the individual test values is repeated. When the individual authentication data of a predetermined number or more is received (step S116: YES), the production control unit 203 has not succeeded in the individual authentication of the main control unit 10, and the authentication processing of the current pachinko gaming machine 1 has not been successful. (Step S117), the process proceeds to step S118. In step S118, the effect control unit 203 interrupts the processing based on the control command data and the accompanying data, discards the data, and sends a notification signal for notifying the illegal act to the symbol display unit 104 and the lamp control unit 205. Or after transmitting to the center control apparatus etc. which manage the pachinko game machine 1, a series of processes are complete | finished. In the process of step S118, the effect control unit 203 may perform only one of data discarding and notification.

  Based on the received notification signal, the symbol display unit 104, the lamp control unit 205, and the like perform an effect of notifying the main control unit 10 that there is a risk of fraud. This effect is, for example, causing a character that does not normally appear in the symbol display unit 104 to appear, or causing a character that normally appears to appear in a manner different from the normal. Further, the brightness of the symbol display unit 104 may be changed, the color may be changed, or the lamp control unit 205 may be controlled to display a predetermined lamp. In any case, when the employee of the game shop passes in front of the pachinko gaming machine 1, it is only necessary to be aware of the state. This effect may be an effect that the customer does not notice the state or an effect that the customer can easily notice. If the production is easily noticed by the customer, fraud can be efficiently suppressed.

  Further, the notification signal may include information on the gaming state of the pachinko gaming machine 1 such as “Big hit” and “Probability changing”. Based on the information on the gaming state, it may be determined whether or not an illegal act is performed by a center control device that manages the pachinko gaming machine 1 or the like. For example, there may be a case where winnings are concentrated during jackpots or probability fluctuations even if the winnings are concentrated. Therefore, it is better to determine whether or not there is a risk of fraudulent behavior under conditions different from other states during jackpots or probability fluctuations. Moreover, you may make it output the information regarding a gaming state as another signal, without including in a notification signal. In this case, the employee determines whether there is a risk of fraud based on both the notification signal and the information regarding the gaming state.

  Next, of the processes shown in FIGS. 12, 13, and 14, the packet information used for generating the synchronization code in the main control unit 10 and the operation authentication expected value changing process in the effect control unit 203 are changed. A specific example will be described. FIG. 15 is a sequence diagram illustrating an example of the flow of data among the main control unit 10, the rear stage unit 20, and the effect control unit 203.

  First, the main control unit 10 proceeds to the process of step S121, determines the number of divisions used for the current individual authentication process by an arbitrary method, and then proceeds to step S122. For example, the main control unit 10 determines that the current number of divisions is three. In step S122, the main control unit 10 divides a predetermined program code stored in advance in the storage area of the ROM 10b into three blocks (storage areas), and uses the program code stored in each block 3 One individual test value is generated (step S122), and the individual test value is subjected to encryption processing to generate individual authentication data (step S123).

  Subsequently, the main control unit 10 selects the type of packet information used for generating the synchronization code, and generates a synchronization code based on the selected packet information (step S124). Specifically, it is packet information of either intermittent packet information or continuous packet information, and is determined at the time of the process related to the previous authentication. Note that the first time is determined in advance between the post-stage unit 20 and the effect control unit 203, and here, continuous packet information is used. Then, the main control unit 10 performs an encryption process on the generated synchronization code to generate operation authentication data (step S125), generates a control signal with authentication data together with the individual authentication data, and produces an effect control unit. It transmits to 203 (step S126). Thereafter, the main control unit 10 selects the type of packet information used for generating the synchronization code in the next authentication-related process based on the number of divisions determined in step S121 (step S127). Here, since the number of divisions = 3 and an odd number, the type of packet information to be used next time is changed from continuous packets to intermittent packet information.

  Next, processing in the effect control unit 203 will be described. When the production control unit 203 receives the control signal with authentication data transmitted from the main control unit 10 (step S128), the production control unit 203 extracts the individual authentication data and the operation authentication data from the control signal with authentication data, and the individual from the individual authentication data. An inspection value is extracted (step S129). Then, the effect control unit 203 adds the control command data and the accompanying data to the operation authentication data to generate a control signal with operation authentication data, and transmits the control signal with operation authentication data to the subsequent stage unit 20 (step S130). Thereafter, the effect control unit 203 performs a combination process on the extracted individual test value using the same half group operation as that of the main control unit 10 as the individual authentication process (step S131). Thereafter, the combined result is collated with the individual authentication expected value held in advance (step S132), and when it matches the individual authentication expected value, the effect control unit 203 determines that the individual authentication of the main control unit 10 is successful. (Step S132). Here, when combining processing is performed using three individual test values, it matches with the individual authentication expected value, and it is found that the current number of connections = 3. Thereafter, the effect control unit 203 suspends the processing related to authentication until the intermediate authentication information signal transmitted from the subsequent unit 20 is received.

  Next, processing in the rear stage unit 20 will be described. When receiving the control signal with operation authentication data transmitted from the effect control unit 203 (step S133), the rear stage unit 20 extracts the operation authentication data from the control signal with operation authentication data and extracts the synchronization code from the operation authentication data. (Step S134). Then, the post-stage unit 20 calculates the difference between the packet information included in the extracted synchronization code as the intermediate operation authentication process, and confirms the correlation between the packet information (step S135).

  Subsequently, the rear stage unit 20 collates the information indicated by the calculated difference value with the intermediate operation authentication expected value held in advance (step S136). Specifically, the expected intermediate operation authentication value is information indicating a correlation between packet information in either type of continuous or intermittent packet information. It is determined in advance between the main control unit 10 and the effect control unit 203 whether to read the intermediate operation authentication expected value of continuous or intermittent packets, and here, it is always continuous packet information. This time, since the packet information type and the intermediate operation authentication expected value transmitted from the main control unit 10 via the effect control unit 203 are continuous packet information, both are the same (step S136). Then, the post-stage unit 20 generates an intermediate operation authentication result indicating the same, performs an encryption process on the result, generates intermediate authentication information indicating the same (step S137), and performs intermediate authentication indicating the content of the intermediate authentication information. The information signal is transmitted to the effect control unit 203 (step S138).

  The processing in the effect control unit 203 will be described again. When the production control unit 203 receives the intermediate authentication information signal transmitted from the rear stage unit 20 (step S139), the effect control unit 203 extracts the intermediate operation authentication result in the rear stage unit 20 indicated by the intermediate authentication information signal. Then, the effect control unit 203 refers to the extracted intermediate motion authentication result as the motion authentication process, and collates it with the motion authentication expected value held in advance as an expected value (step S140). The expected operation authentication value is information indicating whether the intermediate operation authentication result is the same or not. Whether to read the same or non-identical operation authentication expected value is determined at the time of the process related to the previous authentication. Note that the first time is determined in advance between the main control unit 10 and the rear stage unit 20, and here, it is assumed that the information indicates the same. This time, since the intermediate operation authentication result and the operation authentication expectation value transmitted from the rear stage unit 20 are information indicating the same, both result in coincidence (step S140). When the intermediate operation authentication result matches the expected operation authentication value, the effect control unit 203 has succeeded in the operation authentication of the main control unit 10 and the subsequent stage unit 20 (step S140), and together with the individual authentication result in step S132. Then, it is determined that the authentication process of the pachinko gaming machine 1 this time was successful (step S141). After that, the effect control unit 203 selects the type of information to be read as the operation authentication expected value in the next authentication process based on the number of connections found in step S131. (Step S142). Here, since the number of connections = 3 and an odd number, the type of expected operation authentication value to be used next time is changed from the same to information indicating non-identity. This is the flow of a series of selection processes.

  Let us move on to the explanation of the second processing. First, the main control unit 10 proceeds to the process of step S143, determines the number of divisions used for the current individual authentication process by an arbitrary method, and then proceeds to step S144. For example, the main control unit 10 determines that the current number of divisions is four. In step S144, the main control unit 10 divides a predetermined program code stored in advance in the storage area of the ROM 10b into four blocks (storage areas), and uses the program code stored in each block to 4 One individual test value is generated (step S144), and the individual authentication value is subjected to encryption processing to generate individual authentication data (step S145).

  Subsequently, the main control unit 10 selects the type of packet information used for generating the synchronization code, and generates a synchronization code based on the selected packet information (step S146). Specifically, it is packet information of either intermittent packet information or continuous packet information, and is determined at the time of the process related to the previous authentication. Here, it is intermittent packet information. Then, the main control unit 10 performs encryption processing on the generated synchronization code to generate operation authentication data (step S147), generates a control signal with authentication data together with the individual authentication data, and produces an effect control unit. It transmits to 203 (step S148). Thereafter, the main control unit 10 selects the type of packet information used for generating the synchronization code in the next authentication-related process based on the number of divisions determined in step S143 (step S149). Here, since the number of divisions = 4 and an even number, the type of packet information to be used next time continues with intermittent packet information.

  Next, processing in the effect control unit 203 will be described. When the production control unit 203 receives the control signal with authentication data transmitted from the main control unit 10 (step S150), the production control unit 203 extracts the individual authentication data and the operation authentication data from the control signal with authentication data, and the individual from the individual authentication data. An inspection value is extracted (step S151). Then, the effect control unit 203 adds control command data and accompanying data to the operation authentication data to generate a control signal with operation authentication data, and transmits the control signal with operation authentication data to the subsequent stage unit 20 (step S152). Thereafter, the effect control unit 203 performs a combination process on the extracted individual test value using the same half-group operation as that of the main control unit 10 as the individual authentication process (step S153). Thereafter, the combined result is collated with the expected individual authentication value held in advance (step S154), and if it matches the expected individual authentication value, the effect control unit 203 determines that the individual authentication of the main control unit 10 was successful. (Step S154). Here, when the combination processing is performed using the four individual test values, it matches with the individual authentication expected value, and it is found that the current number of connections = 4. Thereafter, the effect control unit 203 suspends the processing related to authentication until the intermediate authentication information signal transmitted from the subsequent unit 20 is received.

  Next, processing in the rear stage unit 20 will be described. When receiving the control signal with operation authentication data transmitted from the effect control unit 203 (step S155), the rear stage unit 20 extracts the operation authentication data from the control signal with operation authentication data and extracts the synchronization code from the operation authentication data. (Step S156). Then, the post-stage unit 20 calculates the difference between the packet information included in the extracted synchronization code as the intermediate operation authentication process, and confirms the correlation between the packet information (step S157).

  Subsequently, the subsequent stage unit 20 collates the information indicated by the calculated difference value with the intermediate operation authentication expected value held in advance (step S158). More specifically, whether the intermediate operation authentication expected value of the continuous or intermittent packet is read is always continuous packet information here, as in the previous authentication process. In this case, since the type of packet information transmitted from the main control unit 10 via the effect control unit 203 is intermittent packet information and the type of intermediate operation authentication expectation value is continuous packet information, both result in non-identity ( Step S158). Then, the post-stage unit 20 generates an intermediate operation authentication result indicating non-identity, performs encryption processing on the result, generates intermediate authentication information indicating non-identity (step S159), and indicates the content of the intermediate authentication information The intermediate authentication information signal is transmitted to the effect control unit 203 (step S160).

  The processing in the effect control unit 203 will be described again. When the production control unit 203 receives the intermediate authentication information signal transmitted from the rear stage unit 20 (step S161), the effect control unit 203 extracts the intermediate operation authentication result in the rear stage unit 20 indicated by the intermediate authentication information signal. Then, the effect control unit 203 refers to the extracted intermediate motion authentication result as the motion authentication process, and collates with the motion authentication expected value held in advance as the expected value (step S162). Whether to read the same or non-identical operation authentication expected value is determined at the time of the process related to the previous authentication. Here, it is information indicating non-identity. In this case, since the intermediate operation authentication result and the operation authentication expected value transmitted from the rear stage unit 20 are information indicating non-identity, both result in coincidence (step S162). When the intermediate operation authentication result matches the expected operation authentication value, the performance control unit 203 has succeeded in the operation authentication of the main control unit 10 and the subsequent stage unit 20 (step S162), and together with the individual authentication result in step S154. Then, it is determined that the authentication process of this pachinko gaming machine 1 was successful (step S163). Thereafter, the effect control unit 203 selects the type of information to be read as the operation authentication expected value in the next authentication-related process, based on the number of connections found in step S153. (Step S164). Here, since the number of connections = 4 and an even number, the type of expected operation authentication value to be used next time continues with information indicating non-identity. This is the flow of a series of selection processes.

  Turning to the description of the third process. First, the main control unit 10 proceeds to the process of step S165, determines the number of divisions used for the current individual authentication process by an arbitrary method, and then proceeds to step S166. For example, the main control unit 10 determines that the current number of divisions is five. In step S166, the main control unit 10 divides a predetermined program code stored in advance in the storage area of the ROM 10b into five blocks (storage areas), and uses the program code stored in each block. One individual test value is generated (step S166), and the individual test value is subjected to encryption processing to generate individual authentication data (step S167).

  Subsequently, the main control unit 10 selects the type of packet information used for generating the synchronization code, and generates a synchronization code based on the selected packet information (step S168). Specifically, it is packet information of either intermittent packet information or continuous packet information, and is determined at the time of the process related to the previous authentication. Here, it is intermittent packet information. Then, the main control unit 10 encrypts the generated synchronization code to generate operation authentication data (step S169), generates a control signal with authentication data together with the individual authentication data, and produces an effect control unit. It transmits to 203 (step S170). Thereafter, the main control unit 10 selects the type of packet information used for generating the synchronization code in the next authentication-related process based on the number of divisions determined in step S165 (step S171). Here, since the number of divisions = 5 and an odd number, the type of packet information to be used next time is changed from intermittent packets to continuous packet information.

  Next, processing in the effect control unit 203 will be described. When the production control unit 203 receives the control signal with authentication data transmitted from the main control unit 10 (step S172), the production control unit 203 extracts the individual authentication data and the operation authentication data from the control signal with authentication data, and the individual from the individual authentication data. An inspection value is extracted (step S173). Then, the effect control unit 203 adds the control command data and the accompanying data to the operation authentication data to generate a control signal with operation authentication data, and transmits the control signal with operation authentication data to the subsequent stage unit 20 (step S174). Thereafter, the effect control unit 203 performs a combination process on the extracted individual test value using the same half group operation as that of the main control unit 10 as the individual authentication process (step S175). Thereafter, the combined result is collated with the individual authentication expected value held in advance (step S176), and when it matches the individual authentication expected value, the effect control unit 203 determines that the individual authentication of the main control unit 10 is successful. (Step S176). Here, when combining processing is performed using five individual test values, it matches with the individual authentication expected value, and it is found that the current number of connections = 5. Thereafter, the effect control unit 203 suspends the processing related to authentication until the intermediate authentication information signal transmitted from the subsequent unit 20 is received.

  Next, processing in the rear stage unit 20 will be described. Upon receiving the control signal with operation authentication data transmitted from the effect control unit 203 (step S177), the rear stage unit 20 extracts the operation authentication data from the control signal with operation authentication data and extracts the synchronization code from the operation authentication data. (Step S178). Then, the post-stage unit 20 calculates the difference between the packet information included in the extracted synchronization code as the intermediate operation authentication process, and confirms the correlation between the packet information (step S179).

  Subsequently, the rear stage unit 20 collates the information indicated by the calculated difference value with the intermediate operation authentication expected value held in advance (step S180). More specifically, whether the intermediate operation authentication expected value of the continuous or intermittent packet is read is always continuous packet information here, as in the previous authentication process. In this case, since the type of packet information transmitted from the main control unit 10 via the effect control unit 203 is intermittent packet information and the type of intermediate operation authentication expectation value is continuous packet information, both result in non-identity ( Step S180). Then, the post-stage unit 20 generates an intermediate operation authentication result indicating non-identity, performs encryption processing on the result, generates intermediate authentication information indicating non-identity (step S181), and indicates the content of the intermediate authentication information The intermediate authentication information signal is transmitted to the effect control unit 203 (step S182).

  The processing in the effect control unit 203 will be described again. When the production control unit 203 receives the intermediate authentication information signal transmitted from the rear stage unit 20 (step S183), the effect control unit 203 extracts the intermediate operation authentication result in the rear stage unit 20 indicated by the intermediate authentication information signal. Then, the effect control unit 203 refers to the extracted intermediate motion authentication result as the motion authentication process, and collates with the motion authentication expected value held in advance as an expected value (step S184). Whether to read the same or non-identical operation authentication expected value is determined at the time of the process related to the previous authentication. Here, it is information indicating non-identity. In this case, since the intermediate operation authentication result and the operation authentication expected value transmitted from the subsequent stage unit 20 are information indicating non-identity, both result in coincidence (step S184). When the intermediate operation authentication result matches the expected operation authentication value, the performance control unit 203 has succeeded in the operation authentication of the main control unit 10 and the subsequent stage unit 20 (step S184), and is combined with the individual authentication result in step S176. Then, it is determined that the authentication process of this pachinko gaming machine 1 was successful (step S185). Thereafter, the effect control unit 203 selects the type of information to be read as the operation authentication expected value in the next authentication process based on the number of connections found in step S175. (Step S186). Here, since the number of connections = 5 and an odd number, the type of expected operation authentication value to be used next time is changed from non-identical to information indicating the same. The above is the flow of a series of selection processes.

  The effect control unit 203 may perform the individual authentication process using the individual authentication data not when the individual authentication data is received but when the plurality of individual authentication data are received. In this case, for example, when the presentation control unit 203 receives the first individual authentication data together with the first control command data and the first associated data of the first control command, the control command is not performed and the control command is not performed. The processing based on the first control command data and the first associated data is performed. Then, when the presentation control unit 203 receives the second individual authentication data together with the second control command data of the second control command and the second accompanying data, the second control command data of the second control command Before performing the process based on the second associated data, the individual authentication process using the first individual authentication data is performed. At this time, the effect control unit 203 may perform the individual authentication process using both the first individual authentication data and the second individual authentication data.

  Further, the post-stage unit 20 does not delete all the data in each memory every time the processing related to authentication is completed, but is the operation stored last in each memory, that is, the operation generated last in the main control unit 10 The inspection value may be stored without being erased, and other data in the memory may be erased. Then, the operation authentication is performed using the operation inspection value generated at the end of the process related to the current authentication and the operation inspection value generated first in the process related to the next authentication. Thereby, since the continuity of the operation of the pachinko gaming machine 1 can be authenticated between the process related to the current authentication and the process related to the next authentication, the authentication strength in the operation authentication can be improved.

  As described above, in the first embodiment, the main control unit 10 divides predetermined data (predetermined program code) stored in advance to generate individual test values, and is divided as processing related to operation authentication. On the basis of the number of pieces of data (number of divisions), the type of packet information used for generating the synchronization code is selected. The post-stage unit 20 checks whether or not the correlation of the packet information generated by the main control unit 10 is the same as the expected correlation value (intermediate operation authentication expected value) stored in advance as a process related to the operation authentication. (Intermediate operation authentication process). The production control unit 203 performs individual authentication using the individual test value, and as a process related to the operation authentication, the verification result in the subsequent stage 20 (intermediate motion authentication result) is stored in advance as the verification result in the subsequent stage 20. It is determined whether or not the expected value (operation authentication expected value) matches (operation authentication processing). In addition, the effect control unit 203 changes the expected operation authentication value based on the number of individual test values (number of connections) that are targets of the half group calculation when the individual authentication is successful. The number of divisions is a value that only the main control unit 10 can know, and the number of connections is a value that the effect control unit 203 can know only after successful individual authentication. Therefore, the fraudster cannot know the switching timing of the packet information used for generating the synchronization code in the main control unit 10 and the expected value in the effect control unit 203. For this reason, it is possible to prevent an unauthorized person from generating the synchronization code illegally, and to improve the authentication strength for the processing among the main control unit 10, the subsequent stage unit 20, and the production control unit 203, and Actions and malfunctions of gaming machines can be detected, and execution of unauthorized control commands resulting from these can be prevented.

  Further, in the first embodiment, as the operation authentication process in the rear stage unit 20 and the effect control unit 203, the rear stage unit 20 has a correlation between the packet information generated by the main control unit 10 in the process related to the current authentication. It is checked whether or not the expected correlation value (intermediate operation authentication expected value) stored in advance is the same (intermediate operation authentication). Then, the effect control unit 203 predicts whether the collation result (intermediate operation authentication result) transmitted from the subsequent stage unit 20 in the process related to the current authentication is the same or non-identical collation result (operation authentication). (Expected value) is held, and it is determined whether or not the received collation result matches (operation authentication). Therefore, even if the operation authentication is successful, the information on the collation result transmitted from the subsequent stage unit 20 to the effect control unit 203 may include the same or non-identical types of information. Furthermore, whether the same or non-identical collation result information is transmitted depends on the number of divisions that only the main control unit 10 can know. For this reason, a fraudster who attempts to illegally steal a data signal transmitted / received between the rear stage unit 20 and the production control unit 203 has the same verification result that is the same or non-identical in the process related to the authentication. I can't know. Accordingly, the cheating person can be disturbed, and the authentication strength for the process between the rear stage unit 20 and the production control unit 203 can be improved.

  Further, in the first embodiment, as the authentication process of the pachinko gaming machine 1, individual authentication of the main control 10 is performed by the effect control unit 203, and operation authentication is performed by both the rear stage unit 20 and the effect control unit 203. Therefore, in addition to the malfunction of the pachinko gaming machine 1 caused by the above-mentioned fraudulent act on the main control unit 10 and noise, the fraudulent act and malfunction on the rear stage unit 20 can be detected. For example, even if an unauthorized control unit equipped with a signal switching circuit or the like is interposed between the rear stage unit 20 and the effect control unit 203, the unauthorized control unit is not limited to the effect control unit 203 based on the number of connections. Since it is not possible to know the switching timing of the operation authentication expected value at the production control unit 203, the fraudulent act can be detected by the effect control unit 203, and the security strength of the pachinko gaming machine 1 as a whole can be improved.

  In the first embodiment, as authentication processing of the pachinko gaming machine 1, individual authentication is performed by the effect control unit 203, and operation authentication is performed by the rear stage unit 20 and the effect control unit 203. That is, since the latter stage part 20 performs a part of authentication process, the increase in the processing load of CPU which comprises the effect control part 203 can be suppressed. For this reason, the processing speed of the production | presentation control part 203 falls, and generation | occurrence | production of problems, such as the display for production | generation not being performed smoothly, can be prevented.

  Furthermore, in this Embodiment 1, since the back | latter stage part 20 is provided in the back | latter stage of the production | presentation control part 203, the difference of the processing capability between CPU10a which comprises the main control part 10, and CPU203a which comprises the production | generation control part 203 In addition, a difference in storage capacity between the ROM 10b or RAM 10c constituting the main control unit 10 and the ROM 203b or RAM 203c constituting the effect control unit 203 can be absorbed by the rear stage unit 20. Thereby, despite the difference in processing capacity and storage capacity between the main control unit 10 and the effect control unit 203, the security level between the main control unit 10 and the effect control unit 203 can be maintained. it can.

  For example, the processing capacity of the CPU 10 a constituting the main control unit 10 and the storage capacity of the ROM 10 b and RAM 10 c constituting the main control unit 10 are the processing capacity of the CPU 203 a constituting the effect control unit 203 and the ROM 203 b constituting the effect control unit 203. When there is a margin in comparison with the storage capacity of the RAM 203c, the main control unit 10 uses the production control unit 203 to obtain authentication data obtained by performing complex or advanced encryption processing on each inspection value. The post-stage unit 20 performs processing related to authentication using the received authentication data, and generates intermediate authentication information by performing relatively simple or low-level encryption processing on the obtained result and the like And transmitted to the effect control unit 203. And the production | presentation control part 203 performs the process regarding authentication using intermediate | middle authentication information. With this configuration, the pachinko gaming machine 1 can maintain a high security level without adopting a complicated or advanced decoding method in the effect control unit 203.

  Further, the processing capacity of the CPU 203a constituting the effect control unit 203 and the storage capacity of the ROM 203b and RAM 203b constituting the effect control unit 203 are the processing ability of the CPU 10a constituting the main control unit 10 and the ROM 10b constituting the main control unit 10. When there is a margin in comparison with the storage capacity of the RAM 10c, the main control unit 10 uses the inspection data as authentication data as it is, or the authentication data obtained by performing relatively simple or low-level encryption processing on the effect control unit. The post-stage unit 20 performs processing related to authentication using the received authentication data, and performs complicated or advanced encryption processing on the obtained result and the like, and intermediate authentication information Is generated and transmitted to the effect control unit 203. And the production | presentation control part 203 performs the process regarding authentication using intermediate | middle authentication information. With this configuration, the pachinko gaming machine 1 can maintain a high security level without adopting a complicated or advanced encryption method in the main control unit 10.

  This is not only the case where there is a difference in the processing capacity of the CPUs 10a and 203a constituting the main control unit 10 and the effect control unit 203, and the storage capacity of the ROMs 10b and 203b and the RAMs 10c and 203c, respectively. Although there is no significant difference, when the CPU 10a constituting the main control unit 10 or the CPU 203a constituting the effect control unit 203 changes all or a part of one of the programs to be executed (version upgrade, etc.) The same applies to a case where a formal difference occurs between the main control unit 10 and the effect control unit 203 in a data structure such as a value or intermediate authentication information.

Moreover, in this Embodiment 1, as a process regarding the operation | movement authentication in the back | latter stage part 20 and the presentation control part 203, the back | latter stage part 20 is the operation | movement test value produced | generated in the main control part 10, and transmitted via the presentation control part 203. Are compared with the expected intermediate operation authentication value held in advance (intermediate operation authentication), and the obtained comparison result (intermediate operation authentication result) is transmitted to the effect control unit 203. Then, the effect control unit 203 determines whether or not the collation result (intermediate operation authentication result) transmitted from the subsequent stage unit 20 matches the operation authentication expected value held in advance (operation authentication). Further, in synchronization with the main control unit 10 switching the generation method of the next operation inspection value based on the current number of divisions, the effect control unit 203 determines the next operation authentication expected value based on the current combination number. The type is switched.
That is, the process related to the operation authentication is integrally executed by both the rear stage unit 20 and the effect control unit 203. Then, based on the number of connections determined by the effect control unit 203 that performs individual authentication, a process for switching the expected operation authentication value held by itself is executed.

  However, this Embodiment 1 is not limited to this, The process regarding operation | movement authentication is mainly performed in the back | latter stage part 20, and the production | generation control part 203 is limited to confirming the operation | movement authentication result of the back | latter stage part 20. A configuration is also possible. At this time, in order to execute the operation authentication expected value switching process held by the rear stage unit 20 based on the number of connections determined by the production control unit 203 that performs the individual authentication, the stage control unit 203 Generates information (switching information) indicating whether to switch the type of expected operation authentication value to be used for the next operation authentication (or which type to select), and the next operation after determining the number of connections It may be transmitted to the rear stage unit 20 until the authentication.

  Specifically, the rear stage unit 20 determines whether or not the motion inspection value generated by the main control unit 10 and transmitted via the effect control unit 203 matches the motion authentication expected value held in advance (operation Authentication), and the obtained operation authentication result is transmitted to the effect control unit 203. Next, the effect control unit 203 confirms whether or not the operation authentication result transmitted from the rear stage unit 20 has been successful. Then, when the result of the operation authentication is successful, the production control unit 203 is that the result of the individual authentication performed by itself is successful, and that the authentication process of this pachinko gaming machine 1 is successful. to decide. Thereafter, the effect control unit 203 generates operation authentication expected value switching information used for the next operation authentication in the subsequent stage unit 20 based on the current number of connections, and transmits the information to the subsequent stage unit 20. In this way, the processing related to the operation authentication is mainly executed in the rear stage unit 20, and the production control unit 203 is configured such that the operation authentication result of the rear stage unit 20 is confirmed. Compared with the case where the effect control unit 203 executes the process integrally, an increase in the processing load of the CPU constituting the effect control unit 203 can be suppressed, and the effect display due to the reduction in the processing speed of the effect control unit 203 can be suppressed. Occurrence of defects and the like can be prevented.

  At this time, the post-stage unit 20 does not need to always transmit the operation authentication result obtained regardless of the success or failure of the operation authentication to the effect control unit 203, and the operation authentication is unsuccessful only when the operation authentication is unsuccessful. It can also be configured to generate an authentication failure signal indicating that it has occurred and transmit it to the effect control unit 203. When the production control unit 203 has not received an authentication unsuccessful signal from the rear stage unit 20, the rear stage unit 20 considers that the operation authentication has succeeded, and the result of the individual authentication performed by itself has been successful. At the same time, it may be determined that the authentication process of the pachinko gaming machine 1 is successful. By doing in this way, compared with the case where the operation | movement authentication result is always transmitted to the effect control part 203 from the back | latter stage part 20, the increase in the processing load of CPU which comprises the effect control part 203 can be suppressed further.

<< Embodiment 2 >>
Hereinafter, the pachinko gaming machine 1 according to the second embodiment of the present invention will be described. The pachinko gaming machine 1 according to the second embodiment is different from the pachinko gaming machine 1 according to the first embodiment in the processing related to authentication at the rear stage 20 and the peripheral part 30 (the effect control unit 203). Specifically, in the first embodiment, operation authentication is performed in the rear stage unit 20 and individual authentication is performed in the peripheral unit 30 (production control unit 203), whereas in the second embodiment, the rear stage unit 20 performs authentication. Individual authentication is performed, and operation authentication is performed by the peripheral unit 30 (the effect control unit 203). The points other than this are basically the same as those of the pachinko gaming machine 1 of the first embodiment, including processing related to authentication in the main control unit 10. Hereinafter, the same members as those in the pachinko gaming machine according to the first embodiment are denoted by the same reference numerals, detailed description thereof will be omitted, and different points will be mainly described.

  The rear stage unit 20 includes an expected value storage unit 21 and an intermediate authentication unit 22. The expected value storage means 21 uses, as an individual authentication expected value, an operation value obtained by performing a binary operation using the same data as the predetermined data stored in the data storage means 11 constituting the main control unit 10. Pre-stored. The intermediate authentication means 22 uses the result of individual authentication using the individual authentication data transmitted from the main control unit 10 via the peripheral unit 30 and the individual authentication and operation in the peripheral unit 30 using the switching information described later. Intermediate authentication information used when making a final authentication decision from both sides of the authentication is generated.

  Specifically, the intermediate authentication unit 22 first performs individual authentication using the individual authentication data transmitted from the main control unit 10 via the peripheral unit 30. More specifically, an individual test value is extracted from the individual authentication data added to the control command and transmitted from the main control unit 10 via the peripheral unit 30, and the main control unit 10 It is determined whether or not the individual authentication is successful based on whether or not the calculation result obtained by performing the binary operation satisfying the same combination rule matches the individual authentication expected value stored in the expected value storage unit 21. Further, the intermediate authentication unit 22 determines the type of expected operation authentication value to be used in the next operation authentication performed in the peripheral unit 30 based on the number of individual test values (number of connections) when the individual authentication is successful. Information on whether or not to switch from the expected operation authentication value used in the operation authentication (hereinafter referred to as switching information).

  Then, the post-stage unit 20 performs encryption processing on the individual authentication result and the switching information to obtain intermediate authentication information, which is transmitted to the peripheral unit 30.

  On the other hand, the peripheral unit 30 includes an expected value storage unit 31 and an authentication unit 32. The expected value storage unit 31 stores in advance information indicating a predetermined correlation preset for each type of packet information included in the synchronization code generated by the main control unit 10 as an operation authentication expected value. The authentication unit 32 performs operation authentication using the operation authentication data included in the control signal with authentication data transmitted from the main control unit 10, and the individual authentication result included in the intermediate authentication information transmitted from the subsequent unit 20. In addition, the normality of the final pachinko gaming machine 1 is authenticated from both the individual authentication and the operation authentication.

  Specifically, the peripheral unit 30 first transmits the individual authentication data transmitted from the main control unit 10 to the subsequent unit 20 as it is or as a control signal with individual authentication data added to the control command. Then, operation authentication is performed using the operation authentication data transmitted from the main control unit 10. More specifically, the authentication unit 32 extracts a synchronization code from the operation authentication data transmitted from the main control unit 10, and determines whether packet information included in the extracted synchronization code has a predetermined correlation set in advance. In order to confirm, a difference (not limited to subtraction) between two pieces of packet information generated successively is obtained. Whether or not the operation authentication is successful is determined based on whether or not the information indicated by the difference value matches the operation authentication expected value stored in the expected value storage unit 31. Further, the authentication means 32 selects the type of expected operation authentication value to be used in the next operation authentication based on the switching information included in the intermediate authentication information transmitted from the subsequent stage unit 20.

  Then, the peripheral unit 30 authenticates the pachinko gaming machine 1 when both the individual authentication result included in the intermediate authentication information transmitted from the subsequent unit 20 and the operation authentication result in the authentication unit 32 are successful. The authentication is performed and processing according to the authentication result is performed.

<Rear part>
Hereinafter, the processing related to authentication in the rear stage unit 20 will be described in detail. Since other than that is the same as that of Embodiment 1, description is abbreviate | omitted.
[1] Reception of Control Signal The effect control unit 203 uses the authentication data with authentication data transmitted from the main control unit 10 as it is or uses the individual authentication data not used for authentication by the effect control unit 203 as it is or as control command data and accompanying data. Is transmitted to the post-stage unit 20 as a control signal with individual authentication data added to. When receiving the control signal with individual authentication data, the rear stage unit 20 performs the following processes [2] to [6].
[2] Extraction of individual authentication data The post-stage unit 20 extracts individual authentication data from the control signal with individual authentication data. Next, the rear stage unit 20 extracts the individual test value from the extracted individual authentication data and stores it in the individual test value memory which is a predetermined storage area of the RAM 20c.

[3] Individual authentication The post-stage unit 20 performs individual group authentication on all the individual test values stored in the individual test value memory in the following order, thereby performing the individual authentication of the main control unit 10. Process.
{1} The rear stage unit 20 performs a semi-group operation using all the individual test values stored in the individual test value memory.
{2} The post-stage unit 20 reads an individual authentication expected value stored in advance from a predetermined storage area of the ROM 20b.

The {3} latter-stage unit 20 determines whether or not the combined result in the process {1} matches the individual authentication expected value read in the process {2}.
The post-stage unit 20 determines that the individual authentication has succeeded when the combined result matches the individual authentication expected value. Further, the post-stage unit 20 determines that the individual authentication has not been successful when the combined result and the individual authentication expected value do not match. When individual authentication is successful, the number of connections and the number of divisions naturally match.

When the individual authentication is successful in the processing of {4} {3}, the rear stage unit 20 generates an individual authentication result indicating that the individual authentication is successful.
If the individual authentication is not successful in the process of {5} {3}, the rear stage unit 20 determines whether or not the number of individual authentication data received from the main control unit 10 is equal to or greater than a predetermined number. The predetermined number is an arbitrary number within the range not less than the current number of connections (number of divisions) and not more than the number (maximum number of divisions) in which the program code stored in the program code storage area 400 (see FIG. 4) can be divided. is there.
{5-1} If the number of received individual authentication data is less than a predetermined number, the rear-stage unit 20 determines that the individual authentication is not yet possible and can replace the individual authentication result with the authentication halfway data as, for example, An arbitrary value (for example, all 0 or all 1) having the same data length as the data length of the individual authentication result is generated.
{5-2} If the number of received individual authentication data is greater than or equal to the predetermined number, the post-stage unit 20 determines that the individual authentication has not been successful, and generates an individual authentication result indicating that the individual authentication has not been successful. To do.

[4] Generation of Switching Information The post-stage unit 20 generates switching information for the expected operation authentication value held by the effect control unit 203 according to a predetermined agreement based on the number of connections when the individual authentication is successful. The switching information is information indicating how to change the type of expected operation authentication value used in the next operation authentication performed by the production control unit 203 from the expected operation authentication value used in the current operation authentication. It is. Here, the predetermined agreement is the same as that in which the main control unit 10 selects the type of packet information used for generating the synchronization code, as in the first embodiment. That is, when the number of couplings is an odd number, the switching information for changing the type of expected operation authentication value is generated. When the number of couplings is an even number, the switching information for generating the type of expected operation authentication value currently used is generated. To do. Note that a value obtained by performing a predetermined operation on the switching information and encrypting it may be used, or instead of the switching information, using a value obtained by performing a predetermined operation on the coupling number itself or the coupling number. Also good.

[5] Generation of Intermediate Authentication Information The post-stage unit 20 generates the individual authentication result obtained by the process [3], the switching information obtained by the process [4], or the authentication data by the main control unit 10 for these. The intermediate authentication information is generated by using the same encrypted processing as that when generating. In the process [3], the post-stage unit 20 generates intermediate authentication information indicating that the individual authentication is successful, and generates a result indicating that the individual authentication is not successful. In this case, intermediate authentication information indicating that is generated.

[6] Transmission of intermediate authentication information signal The post-stage unit 20 transmits an intermediate authentication information signal indicating the content of the intermediate authentication information to the effect control unit 203 and is stored in the individual test value memory and the motion test value memory. Erase each piece of data. The means for storing the individual authentication expected value in advance and the means for executing the individual authentication can correspond to, for example, the expected value storage means 21 and the intermediate authentication means 22 shown in FIG.

<Production control unit>
Hereinafter, a case where the effect control unit 203 which is one of the peripheral units 30 performs processing related to authentication will be described in detail. Since other than that is the same as that of Embodiment 1, description is abbreviate | omitted.
[1] Reception of control signal In the production control unit 203, the control signal transmitted from the main control unit 10 is a normal control signal consisting only of control command data and accompanying data, or in addition to control command data and accompanying data, It is determined whether the control signal is a control signal with authentication data to which authentication data is added. When the received control signal is a normal control signal, the effect control unit 203 performs a process related to the effect based on the control command data and the accompanying data, and ends the process related to authentication. On the other hand, when the received control signal is a control signal with authentication data, the effect control unit 203 executes the following processes [2] to [5] on the assumption that the process related to authentication is continued.

[2] Extraction / transmission of individual authentication data and extraction of synchronization code The production control unit 203 extracts the individual authentication data and the operation authentication data from the control signal with authentication data transmitted from the main control unit 10, and extracts the extracted operation. A synchronization code is extracted by performing a decryption process corresponding to the encryption process used when generating the operation authentication data on the authentication data. The effect control unit 203 stores the extracted individual authentication data in the individual test value memory that is a predetermined storage area of the RAM 203c, and the extracted synchronization code in the operation test value memory that is a predetermined storage area of the RAM 203c. Next, control command data and accompanying data are added to the individual authentication data in the individual test value memory to generate a control signal with individual authentication data, and the control signal with individual authentication data is transmitted to the subsequent stage unit 20. The production control unit 203 extracts only the operation authentication data from the control signal with authentication data transmitted from the main control unit 10, and immediately after that, transmits other than the operation authentication data as a control signal with individual authentication data to the subsequent stage unit 20. May be.

[3] Operation Authentication The effect control unit 203 performs operation authentication on the control command output of the main control unit 10 in the following order using a plurality of synchronization codes stored in the operation inspection value memory.
Operation authentication using {1} synchronization code
{1-1} The effect control unit 203 reads a plurality of pieces of packet information in correspondence with the order in which the control commands of the main control unit 10 are output from the plurality of synchronization codes stored in the motion inspection value memory. .
{1-2} The effect control unit 203 includes a packet information generated at a certain timing among a plurality of read packet information, and a packet information generated at a timing after a predetermined generation interval has elapsed from the packet information. Find the difference. This difference is not limited to subtraction, but various arithmetic operations and logical operations can be considered.

{1-3} The effect control unit 203 is information that is shared with the main control unit 10 and is preset for each type of packet information, and indicates a correlation between packet information generated at successive generation timings. Is read out from a predetermined storage area. The expected operation authentication value to be read is one indicating a continuous packet or one indicating an intermittent packet. In the second embodiment, as in the first embodiment, an operation authentication expected value indicating continuous packet information is read.
{1-4} The effect control unit 203 determines whether or not the information indicated by the difference value obtained in the process {1-2} matches the expected operation authentication value read in the process {1-3}. to decide.
The effect control unit 203 determines that the operation authentication is successful when the information indicated by the difference value matches the expected operation authentication value. In addition, the effect control unit 203 determines that the operation authentication has not been successful when the information indicated by the difference value does not match the expected operation authentication value.

When the operation authentication is successful in the processing of {1-5} {1-4}, the effect control unit 203 generates an operation authentication result indicating that the operation authentication is successful.
If the operation authentication is not successful in the processing of {1-6} {1-4}, the effect control unit 203 generates an operation authentication result indicating that the operation authentication is not successful.
In the second embodiment, as in the first embodiment, the type of packet information used for the initial generation of the synchronization code by the main control unit 10 and the type of expected operation authentication value read for the first time by the production control unit 203 are as follows. Since both correspond to continuous packet information, the operation authentication is successful.
[4] Receiving Intermediate Authentication Information Signal, Changing Operation Authentication Expected Value The effect control unit 203 extracts the individual authentication result from the intermediate authentication information signal transmitted from the rear stage unit 20, and obtains the individual authentication result in the rear stage unit 20. Check. In addition, the effect control unit 203 selects the type of expected operation authentication value to be read in the next authentication process according to the switching information included in the intermediate authentication information signal. The switching information in the second embodiment changes the type of expected operation authentication value when the number of connections is odd, and continues the type of expected operation authentication value currently used when the number of connections is even. .

[5] Process Based on Authentication Result The effect control unit 203 uses the operation authentication result obtained in the process [3] and the individual authentication result obtained in the process [4] to authenticate the pachinko gaming machine 1 The gender is authenticated from both the individual authentication and the operation authentication, and the final authentication judgment is made. When both the operation authentication result obtained in the process [3] and the individual authentication result obtained in the process [4] are results indicating successful authentication, the effect control unit 203 receives the received authentication. A process based on the control command data and accompanying data included in the control signal with data is executed, and each data stored in the individual test value memory and the operation test value memory is deleted, and the process related to the authentication is completed. . On the other hand, if either the operation authentication result obtained in the process [3] or the individual authentication result obtained in the process [4] is a result indicating an unsuccessful authentication, the control command data and the accompanying data The processing based on the above is interrupted, these data are discarded, and processing such as notification that fraud has been detected is performed, and each data stored in the individual test value memory and the operation test value memory is deleted. Then, the process related to authentication is terminated. Note that the above-described means for storing the expected operation authentication value and the means for executing the operation authentication can correspond to, for example, the expected value storage means 31 and the authentication means 32 shown in FIG.

  Next, processing related to authentication by the latter stage unit 20 will be described. FIG. 16 is a flowchart illustrating an example of a processing procedure related to authentication performed by the latter-stage unit 20. First, the post-stage unit 20 determines whether or not a control signal as shown in FIG. 5 transmitted from the main control unit 10 via the effect control unit 203 has been received (step S191). When the determination result is “NO”, the rear stage unit 20 repeats the same determination. When the control signal transmitted from the main control unit 10 via the effect control unit 203 is received (step S191: YES), the rear stage unit 20 proceeds to step S192.

  In step S192, the post-stage unit 20 determines whether or not the individual authentication data is included in the received control signal. When individual authentication data is included in the received control signal (step S192: YES), the rear stage unit 20 proceeds to step S193. Here, the determination of whether or not the individual authentication data is included in the control signal is, for example, whether or not the data amount of the control signal is larger than that of the normal control signal, Is performed by determining whether or not any bit constituting the ID or separately provided identification data (not shown) indicates that the individual authentication data is included. In the process of step S192, the post-stage unit 20 does not determine whether or not the individual authentication data is included in the received control signal, but the control command data included in the control signal is a control of a predetermined control command. It may be determined whether it is command data.

  If the received control signal includes individual authentication data (step S192: YES), that is, if the received control signal is a control signal with individual authentication data, the subsequent stage unit 20 receives the received control signal with individual authentication data. The individual authentication data contained in is extracted and decrypted to extract the individual test value (step S193). The rear stage unit 20 stores the extracted individual test value in the individual test value memory, and proceeds to step S194.

  Next, the post-stage unit 20 performs a semi-group operation (joining process) on all the individual test values in the individual test value memory as the individual authentication process (step S194). If there is one test value in the individual test value memory, the process directly proceeds to step S195 without performing the combining process. Then, the post-stage unit 20 collates the operation result (combination result) of the combining process with the held individual authentication expected value, and determines whether or not the combined result matches the individual authentication expected value (step). S195). When the combined result and the individual authentication expected value match (step S195: YES), the rear stage unit 20 determines that the individual authentication of the main control unit 10 is successful, and the individual authentication result indicating that the individual authentication is successful. Is generated (step S196).

  Subsequently, the post-stage unit 20 determines whether or not the number of connections determined in step S194 is a predetermined value (step S197). The predetermined value is an odd number as in the first embodiment. When the number of connections is a predetermined value (step S197: YES), the rear stage unit 20 displays switching information indicating that the type of operation authentication expected value used in the next operation authentication performed by the effect control unit 203 is changed. Generate (step S198), and proceed to step S200. On the other hand, when the number of connections is not a predetermined value (step S197: NO), switching information indicating that the type of the operation authentication expected value used in the operation authentication performed in the next effect control unit 203 is continued without being changed. Generate (step S199), and proceed to step S200.

  On the other hand, in step S195, when the combined result and the individual authentication expected value do not match (step S195: NO), the rear stage unit 20 proceeds to step S191 until receiving a predetermined number or more of individual authentication data (step S201: NO). The process of receiving the individual authentication data and combining the individual test values is repeated. When the individual authentication data of a predetermined number or more is received (step S201: YES), the rear stage unit 20 determines that the individual authentication of the main control unit 10 is unsuccessful, and generates an individual authentication result indicating that the individual authentication is unsuccessful. (Step S202), the process proceeds to Step S200.

  The rear stage unit 20 generates intermediate authentication information by combining the generated individual authentication result and switching information indicating change or continuation (step S200). Thereafter, the post-stage unit 20 generates an intermediate authentication information signal indicating the content of the generated intermediate authentication information, transmits it to the effect control unit 203 (step S203), and stores it in the individual test value memory and the motion test value memory. In addition to deleting the received data and discarding the received control command data and accompanying data (step S204), the series of processes is terminated.

  In addition, if individual authentication data is not included in the received control signal in step S192, that is, if the received control signal is a normal control signal (step S192: NO), the subsequent stage unit 20 performs the authentication process. And the received control command data and accompanying data are discarded (step S204), and the series of processing ends.

  Next, processing related to authentication by the effect control unit 203 will be described. FIG. 17 is a flowchart illustrating an example of a processing procedure related to authentication by the effect control unit 203. First, the effect control unit 203 determines whether or not a control signal has been received from the main control unit 10 (step S211). When the determination result is “NO”, the effect control unit 203 repeats the determination. And if a control signal is received from the main control part 10, the judgment result of step S211 will be "YES", and the production | presentation control part 203 will progress to step S212.

  In step S212, the effect control unit 203 determines whether authentication data is included in the received control signal. If the determination result in step S212 is “YES”, that is, if the received control signal includes authentication data, the effect control unit 203 proceeds to step S213. Here, the determination as to whether or not the authentication data is included in the control signal is, for example, whether or not the data amount of the control signal is larger than that of the normal control signal, and whether the control command data or the accompanying data is included in the control signal. It is determined whether or not any bit constituting or identification data (not shown) provided separately indicates that the authentication data is included, or the control command data included in the control signal is It may be determined whether or not the control command data is a predetermined control command set in advance for performing the authentication process.

  When authentication data is included in the received control signal (step S212: YES), that is, when the received control signal is a control signal with authentication data, the effect control unit 203 is included in the received control signal with authentication data. The individual authentication data and the operation authentication data are extracted, the operation authentication data is decrypted, and the synchronization code is extracted (step S213). The effect control unit 203 stores the extracted individual authentication data in the individual test value memory and the extracted synchronization code in the operation test value memory, and proceeds to step S214. In step S212, if the received control signal does not include authentication data, that is, if the received control signal is a normal control signal (step S212: NO), the effect control unit 203 performs an authentication process. Instead, the process proceeds to step S222. Next, the effect control unit 203 adds the control command data and accompanying data to the individual authentication data stored in the individual test value memory to generate a control signal with individual authentication data, and outputs the control signal with individual authentication data to the subsequent stage. It transmits to the part 20 (step S214), and it progresses to step S215.

  In step S215, the effect control unit 203 calculates the difference between the packet information acquired from the synchronization code stored in the operation inspection value memory as the operation authentication process, and the correlation between the packet information indicated by the obtained difference value. Is confirmed (step S215). Then, the effect control unit 203 reads the operation authentication expected value previously held as the expected value, and determines whether the information indicated by the difference value matches the operation authentication expected value (step S216). When the information indicated by the difference value matches the action authentication expected value (step S216: YES), the effect control unit 203 determines that the action authentication is successful (step S217), and proceeds to step S218. If there is one packet information included in the extracted synchronization code, the effect control unit 203 returns to step S211 without performing the process of step S215, and repeats the subsequent processes until a plurality of pieces of packet information are acquired. . On the other hand, if the information indicated by the difference value does not match the expected operation authentication value (step S216: NO), the effect control unit 203 has not succeeded in the operation authentication, and the authentication process of the pachinko gaming machine 1 this time has failed. It is judged that there was (step S225), and it progresses to step S226.

  Subsequently, the effect control unit 203 determines whether or not the intermediate authentication information signal transmitted from the subsequent unit 20 has been received (step S218), and repeats the same determination until it is received. Then, when the intermediate authentication information signal transmitted from the rear stage unit 20 is received (step S218: YES), the effect control unit 203 determines whether or not the individual authentication result in the rear stage unit 20 indicated by the intermediate authentication information signal is successful. (Step S219). When the individual authentication result included in the intermediate authentication information indicates success (step S219: YES), the production control unit 203 succeeds in the authentication process of the pachinko gaming machine 1 this time together with the operation authentication result obtained in step S217. (Step S220), the process proceeds to step S222. If the individual authentication result included in the intermediate authentication information is not a result indicating success (step S219: NO), the production control unit 203 has not succeeded in individual authentication in the rear stage unit 20, and this pachinko game It is determined that the authentication process of the machine 1 was unsuccessful (step S225), and the process proceeds to step S226.

  Subsequently, the effect control unit 203 refers to the switching information stored in the motion inspection value memory (step S221), and the switching information changes the type of expected operation authentication value used in the next motion authentication. Whether or not (step S222). When the switching information indicates a change (step S222: YES), the effect control unit 203 changes the type of expected operation authentication value used in the next operation authentication (step S223), and proceeds to step S224. If the switching information does not indicate a change (step S222: NO), the effect control unit 203 does not change the type of operation authentication expected value used in the next operation authentication, and proceeds to step S224. In step S224, the effect control unit 203 deletes the data stored in the individual test value memory and the motion test value memory and performs a process based on the control command data and the accompanying data, and then ends the series of processes. To do.

  In step S226, the effect control unit 203 interrupts the processing based on the control command data and the accompanying data, discards the data, and sends a notification signal for notifying the cheating to the symbol display unit 104 and the lamp control unit 205. Or after transmitting to the center control apparatus etc. which manage the pachinko game machine 1, a series of processes are complete | finished. In the process of step S226, the effect control unit 203 may perform only one of data discarding and notification.

  Next, in the processes shown in FIGS. 12, 16, and 17, the change process of the packet information used for generating the synchronization code in the main control unit 10 and the change process of the expected operation authentication value in the effect control unit 203 A specific example will be described. FIG. 18 is a sequence diagram illustrating an example of a data flow among the main control unit 10, the rear stage unit 20, and the effect control unit 203.

  First, the main control unit 10 proceeds to the process of step S231, determines the number of divisions used for the current individual authentication process by an arbitrary method, and then proceeds to step S232. For example, the main control unit 10 determines that the current number of divisions is three. In step S232, the main control unit 10 divides a predetermined program code stored in advance in the storage area of the ROM 10b into three blocks (storage areas), and uses the program code stored in each block to 3 Two individual test values are generated (step S232), and the individual test values are encrypted to generate individual authentication data (step S233).

  Next, the main control unit 10 selects the type of packet information used for generating the synchronization code, and generates a synchronization code based on the selected packet information (step S234). Specifically, it is packet information of either intermittent packet information or continuous packet information, and is determined at the time of the process related to the previous authentication. Note that the first time is determined in advance between the post-stage unit 20 and the effect control unit 203, and here, continuous packet information is used. Then, the main control unit 10 performs an encryption process on the generated synchronization code, generates operation authentication data (step S235), generates a control signal with authentication data together with the individual authentication data, and performs production control. The data is transmitted to the unit 203 (step S236). Thereafter, the main control unit 10 selects the type of packet information used for generating the synchronization code in the next authentication-related process based on the number of divisions determined in step S231 (step S237). Here, since the number of divisions = 3 and an odd number, the type of packet information to be used next time is changed from a continuous packet to an intermittent packet.

  Next, processing in the effect control unit 203 will be described. When receiving the control signal with authentication data transmitted from the main control unit 10 (step S238), the effect control unit 203 extracts the individual authentication data and the operation authentication data from the control signal with authentication data, and synchronizes with the operation authentication data. A code is extracted (step S239). Then, the effect control unit 203 adds control command data and accompanying data to the individual authentication data to generate a control signal with individual authentication data, and transmits the control signal with individual authentication data to the subsequent unit 20 (step S240). Thereafter, the effect control unit 203 calculates the difference between the packet information included in the extracted synchronization code, and confirms the correlation between the packet information (step S241). Thereafter, the information indicated by the calculated difference value is collated with the operation authentication expected value held in advance (step S242). Which type of operation authentication expected value to read out, continuous or intermittent packet information, is determined at the time of the previous authentication processing. Note that the first time is determined in advance between the main control unit 10 and the effect control unit 203, and here is continuous packet information. In this case, since the packet information and the operation authentication expected value included in the synchronization code transmitted from the main control unit 10 indicate the continuous packet information, both match each other (step S242). Thereafter, the effect control unit 203 suspends the processing related to authentication until the intermediate authentication information signal transmitted from the subsequent unit 20 is received.

  Next, processing in the rear stage unit 20 will be described. When receiving the control signal with individual authentication data transmitted from the production control unit 203 (step S243), the rear stage unit 20 extracts the individual authentication data from the control signal with individual authentication data and obtains the individual test value from the individual authentication data. Extract (step S244). Then, the post-stage unit 20 performs a combination process on the extracted individual test value using the same half group operation as that of the main control unit 10 as the individual authentication process (step S245). Thereafter, the combined result is compared with the individual authentication expected value held in advance, and if it matches the individual authentication expected value, the rear stage unit 20 determines that the individual authentication of the main control unit 10 has been successful (step S246). Here, when combining processing is performed using three individual test values, it matches with the individual authentication expected value, and it is found that the current number of connections = 3.

  Next, the post-stage unit 20 generates switching information for selecting the type of expected operation authentication value to be used in the next operation authentication performed by the effect control unit 203 based on the number of connections found in step S245 (step S247). ). Here, since the number of connections = 3 and an odd number, switching information indicating that the type of expected operation authentication value to be used next time is changed is generated. Then, the post-stage unit 20 generates the intermediate authentication information indicating that the individual authentication is successful by combining the individual authentication result and the switching information (step S248), generates an intermediate authentication information signal indicating the content of the intermediate authentication information, and The data is transmitted to the control unit 203 (step S249).

  The processing in the effect control unit 203 will be described again. When the production control unit 203 receives the intermediate authentication information signal transmitted from the subsequent stage unit 20 (step S250), it extracts the individual authentication result and the switching information from the intermediate authentication information signal (step S251). Then, when the production control unit 203 confirms that the individual authentication result indicates success, the individual authentication in the rear stage unit 20 is successful, and together with the operation authentication result obtained in step S242, this pachinko gaming machine It is determined that the authentication process 1 is successful (step S252). Then, with reference to the switching information included in the intermediate authentication information, it is determined whether or not the switching information is information for changing the type of expected operation authentication value used in the next operation authentication (step S253). This time, since the operation authentication expected value is continuous packet information and the switching information indicating the change is received, the type of operation authentication expected value to be used next time is changed from continuous packet information to intermittent packet information (step S253). ). This is the flow of a series of selection processes.

  Let us move on to the explanation of the second processing. First, the main control unit 10 proceeds to the process of step S261, determines the number of divisions used for the current individual authentication process by an arbitrary method, and then proceeds to step S262. For example, the main control unit 10 determines that the current number of divisions is four. In step S262, the main control unit 10 divides a predetermined program code stored in advance in the storage area of the ROM 10b into four blocks (storage areas), and uses the program code stored in each block. One individual test value is generated (step S262), and the individual test value is subjected to encryption processing to generate individual authentication data (step S263).

  Next, the main control unit 10 selects the type of packet information used to generate the synchronization code, and generates a synchronization code based on the selected packet information (step S264). Specifically, it is packet information of either intermittent packet information or continuous packet information, and is determined at the time of the process related to the previous authentication. Here, it is intermittent packet information. Then, the main control unit 10 performs an encryption process on the generated synchronization code, generates operation authentication data (step S265), generates a control signal with authentication data together with the individual authentication data, and effects control The data is transmitted to the unit 203 (step S266). After that, the main control unit 10 selects the type of packet information used for generating the synchronization code in the next authentication process based on the number of divisions determined in step S261 (step S267). Here, since the number of divisions = 4 and an even number, the type of packet information to be used next time continues as an intermittent packet.

  Next, processing in the effect control unit 203 will be described. When the production control unit 203 receives the control signal with authentication data transmitted from the main control unit 10 (step S268), it extracts the individual authentication data and the operation authentication data from the control signal with authentication data, and synchronizes with the operation authentication data. A code is extracted (step S269). Then, the effect control unit 203 adds control command data and accompanying data to the individual authentication data to generate a control signal with individual authentication data, and transmits the control signal with individual authentication data to the subsequent unit 20 (step S270). Thereafter, the effect control unit 203 calculates the difference between the packet information included in the extracted synchronization code, and confirms the correlation between the packet information (step S271). Thereafter, the information indicated by the calculated difference value is collated with the operation authentication expected value held in advance (step S272). Which type of operation authentication expected value to read out, continuous or intermittent packet information, is determined at the time of the previous authentication processing. Here, it is intermittent packet information. This time, both the packet information and the operation authentication expected value included in the synchronization code transmitted from the main control unit 10 indicate intermittent packet information, and thus both coincide with each other (step S272). Thereafter, the effect control unit 203 suspends the processing related to authentication until the intermediate authentication information signal transmitted from the subsequent unit 20 is received.

  Next, processing in the rear stage unit 20 will be described. When receiving the control signal with individual authentication data transmitted from the production control unit 203 (step S273), the rear stage unit 20 extracts the individual authentication data from the control signal with individual authentication data, and obtains the individual test value from the individual authentication data. Extract (step S274). Then, the post-stage unit 20 performs a combination process on the extracted individual test value using the same half group operation as that of the main control unit 10 as the individual authentication process (step S275). Thereafter, the combined result is compared with the individual authentication expected value held in advance, and if it matches the individual authentication expected value, the rear stage unit 20 determines that the individual authentication of the main control unit 10 was successful (step S276). Here, when the combination processing is performed using the four individual test values, it matches with the individual authentication expected value, and it is found that the current number of connections = 4.

  Next, the post-stage unit 20 generates switching information for selecting the type of expected operation authentication value to be used in the next operation authentication performed by the effect control unit 203 based on the number of connections found in step S275 (step S277). ). Here, since the number of connections = 4 and an even number, switching information indicating that the type of expected operation authentication value to be used next time continues is generated. Then, the post-stage unit 20 generates the intermediate authentication information indicating the success of the individual authentication by combining the individual authentication result and the switching information (step S278), generates an intermediate authentication information signal indicating the content of the intermediate authentication information, and The data is transmitted to the control unit 203 (step S279).

  The processing in the effect control unit 203 will be described again. When the production control unit 203 receives the intermediate authentication information signal transmitted from the rear stage unit 20 (step S280), it extracts the individual authentication result and the switching information from the intermediate authentication information signal (step S281). Then, when the production control unit 203 confirms that the individual authentication result indicates success, the individual authentication in the rear stage unit 20 is successful, and together with the operation authentication result obtained in step S272, this pachinko gaming machine 1 is determined to have been successful (step S282). Then, with reference to the switching information included in the intermediate authentication information, it is determined whether or not the switching information is information for changing the type of expected operation authentication value used in the next operation authentication (step S283). This time, since the operation authentication expected value is intermittent packet information and the switching information indicating continuation is received, the type of operation authentication expected value to be used next time is continued as the intermittent packet information (step S283). This is the flow of a series of selection processes.

  Turning to the description of the third process. First, the main control unit 10 proceeds to the process of step S291, determines the number of divisions used for the current individual authentication process by an arbitrary method, and then proceeds to step S292. For example, the main control unit 10 determines that the current number of divisions is five. In step S292, the main control unit 10 divides a predetermined program code stored in advance in the storage area of the ROM 10b into five blocks (storage areas), and uses the program code stored in each block. Two individual test values are generated (step S292), and the individual test values are subjected to encryption processing to generate individual authentication data (step S293).

  Next, the main control unit 10 selects the type of packet information used for generating the synchronization code, and generates a synchronization code based on the selected packet information (step S294). Specifically, it is packet information of either intermittent packet information or continuous packet information, and is determined at the time of the process related to the previous authentication. Here, it is intermittent packet information. Then, the main control unit 10 performs an encryption process on the generated synchronization code, generates operation authentication data (step S295), generates a control signal with authentication data together with the individual authentication data, and performs production control. The data is transmitted to the unit 203 (step S296). Thereafter, the main control unit 10 selects the type of packet information used for generating the synchronization code in the next authentication-related process based on the number of divisions determined in step S291 (step S297). Here, since the number of divisions = 5 and an odd number, the type of packet information to be used next time is changed from intermittent packets to continuous packets.

  Next, processing in the effect control unit 203 will be described. When the production control unit 203 receives the control signal with authentication data transmitted from the main control unit 10 (step S298), it extracts the individual authentication data and the operation authentication data from the control signal with authentication data, and synchronizes with the operation authentication data. A code is extracted (step S299). Then, the effect control unit 203 adds control command data and accompanying data to the individual authentication data to generate a control signal with individual authentication data, and transmits the control signal with individual authentication data to the subsequent stage unit 20 (step S300). Thereafter, the effect control unit 203 calculates the difference between the packet information included in the extracted synchronization code, and confirms the correlation between the packet information (step S301). Thereafter, the information indicated by the calculated difference value is collated with the operation authentication expected value held in advance (step S302). Which type of operation authentication expected value to read out, continuous or intermittent packet information, is determined at the time of the previous authentication processing. Here, it is intermittent packet information. This time, both the packet information and the operation authentication expected value included in the synchronization code transmitted from the main control unit 10 indicate the intermittent packet information, and thus both coincide with each other (step S302). Thereafter, the effect control unit 203 suspends the processing related to authentication until the intermediate authentication information signal transmitted from the subsequent unit 20 is received.

  Next, processing in the rear stage unit 20 will be described. When receiving the control signal with individual authentication data transmitted from the effect control unit 203 (step S303), the rear stage unit 20 extracts the individual authentication data from the control signal with individual authentication data, and obtains the individual test value from the individual authentication data. Extract (step S304). Then, the post-stage unit 20 performs a combination process on the extracted individual test value using the same half group operation as that of the main control unit 10 as the individual authentication process (step S305). Thereafter, the combined result is compared with the individual authentication expected value held in advance, and if it matches the individual authentication expected value, the rear stage unit 20 determines that the individual authentication of the main control unit 10 has been successful (step S306). Here, when combining processing is performed using five individual test values, it matches with the individual authentication expected value, and it is found that the current number of connections = 5.

  Next, the post-stage unit 20 generates switching information for selecting the type of expected operation authentication value to be used in the next operation authentication performed by the effect control unit 203 based on the number of connections found in step S305 (step S307). ). Here, since the number of connections = 5 and an odd number, switching information indicating that the type of expected operation authentication value to be used next time is changed is generated. Then, the post-stage unit 20 generates the intermediate authentication information indicating the success of the individual authentication by combining the individual authentication result and the switching information (step S308), generates an intermediate authentication information signal indicating the content of the intermediate authentication information, and The data is transmitted to the control unit 203 (step S309).

  The processing in the effect control unit 203 will be described again. When the production control unit 203 receives the intermediate authentication information signal transmitted from the subsequent stage unit 20 (step S310), it extracts the individual authentication result and the switching information from the intermediate authentication information signal (step S311). Then, when the production control unit 203 confirms that the individual authentication result indicates success, the individual authentication in the rear stage unit 20 is successful, and together with the operation authentication result obtained in step S302, this pachinko gaming machine It is determined that the authentication process 1 is successful (step S312). Then, the switching information included in the intermediate authentication information is referred to, and it is determined whether or not the switching information is information for changing the type of expected operation authentication value used in the next operation authentication (step S313). This time, since the operation authentication expected value is intermittent packet information and the switching information indicating that the change has been received, the type of operation authentication expected value to be used next time is changed from intermittent packet information to continuous packet information (step S313). ). The above is the flow of a series of selection processes.

  Further, although the post-stage unit 20 generates the intermediate authentication information by combining the individual authentication result and the switching information and transmits the intermediate authentication information signal to the effect control unit 203, it is not limited to this. For example, the post-stage unit 20 may generate intermediate authentication information using only the switching information. At this time, the post-stage unit 20 does not notify the effect control unit 203 when the individual authentication at the post-stage unit 20 is successful, and only when the individual authentication at the post-stage unit 20 is unsuccessful. An authentication failure signal is generated and transmitted to the effect control unit 203. The production control unit 203 determines that the normality of the gaming machine 1 could not be authenticated when the operation authentication is successful and the authentication authentication success value is received in the switching information and then the authentication unsuccessful signal is received. Notification etc. are performed. If the authentication unsuccessful signal is not received, it is determined that the individual authentication at the rear stage 20 is not unsuccessful and the individual authentication is considered successful, and the normality of the pachinko gaming machine 1 is combined with the operation authentication result. Judge that authentication was successful.

  As described above, the pachinko gaming machine 1 according to the second embodiment is different from the pachinko gaming machine 1 according to the first embodiment in the processing related to authentication in the rear stage 20 and the peripheral part 30 (the production control unit 203). Individual authentication is performed in the rear stage unit 20, and operation authentication is performed in the peripheral unit 30 (the effect control unit 203), and the same effect as in the first embodiment can be obtained.

<< Embodiment 3 >>
In the said Embodiment 1, 2, although the example which set the back | latter stage part 20 and the production | presentation control part 203 as a separate hardware structure was shown, it is not limited to this.
For example, with respect to the first embodiment, one CPU has the functions of the CPU 20a constituting the rear stage unit 20 and the function of the CPU 203a constituting the presentation control unit 203, and the rear stage unit 20 is configured. The program code stored in the ROM 20b and other fixed data and the program code stored in the ROM 203b constituting the effect control unit 203 and other fixed data are stored in one ROM. Also good. In this case, the transmission / reception of data between the rear stage unit 20 and the effect control unit 203 functions as, for example, a work area of the RAM 20c constituting the rear stage unit 20 and also functions as a work area of the RAM 203c constituting the effect control unit 203. In such a single RAM, it can be realized by copying data from one storage area to another storage area or rewriting an address to be referred to.

  However, in the above case, since one CPU has the functions of two CPUs, the processing load generally increases. Therefore, for example, it is conceivable to perform the processing of the rear stage unit 20 with a dual CPU configuration.

  Since the pachinko gaming machine 1 according to the third embodiment has the rear stage unit 20 and the production control unit 203 configured by one piece of software, in addition to the effects obtained in the first and second embodiments, the following effects can be obtained. can get.

1. Parallel development and information security improvement When the production control unit and the latter part are separated and independent on the software configuration, the production control unit and the latter part can be developed separately in parallel, for example, The following effects can be obtained.

[1] Since the production control unit and the rear stage unit can be designed and developed at the same time, the product development period can be shortened compared to the case where parallel development is impossible.
[2] Since it is possible to take independent development systems for the production control unit and the latter part, confidential business information (for example, an authentication processing method, etc.) when performing design and manufacturing verification of the production control unit and the latter part , Processing related to games, etc.) can be reduced out of the respective development system.

2. Ease of Verification When the production control unit and the rear stage unit are separated and independent on the software configuration, it is possible to individually verify the production control unit and the rear stage unit. Therefore, as compared with the case where verification is performed for a case where the production control unit and the rear stage unit are not separated, each function is closed by a narrow function, so that verification can be performed in a short period of time and with a small number of people.

3. Even if it is not possible to provide a CPU or dedicated integrated circuit separate from the effect control unit as hardware for authentication, an authentication function can be easily added by software.

4). Reduction in processing load of the production control unit When the authentication function implemented in the subsequent unit is implemented by software of the production control unit, the processing load of the production control unit increases. Therefore, it is conceivable to use a dual core CPU as the CPU constituting the production control unit. Since the processing load for realizing the authentication process can be distributed by using the dual core CPU, the authentication function is provided so as not to affect the existing game process of the production control unit as much as possible. The authentication function can be easily realized.

<< Other Embodiments >>
The specific configuration of the present invention is not limited to the above-described embodiments, and any design change or the like within a range not departing from the gist of the present invention is included in the present invention.
For example, in Embodiment 1, although the example which provides the back | latter stage part 20 in the back | latter stage of the production | presentation control part 203 was shown, it is not limited to this, You may provide the back | latter stage part 20 in the back | latter stage of the prize ball control part 204. In this case, the prize ball control unit 204 is not provided with an informing means, but since bidirectional communication is possible between the main control unit 10 and the prize ball control unit 204, the authentication is unsuccessful. The prize ball control unit 204 may transmit data indicating that the authentication has failed to the main control unit 10. Then, the main control unit 10 transmits the data indicating the failure to the effect control unit 203, and the effect control unit 203 performs an illegal act based on the data indicating the failure. Let them know.
Further, in the pachinko gaming machine 1 according to the first to third embodiments, the rear stage unit 20 is configured to include a CPU, a ROM, a RAM, and the like, but is realized as an integrated circuit such as an LSI having similar functions. You may do it.

  In the pachinko gaming machine 1 according to the first to third embodiments, the main control unit 10, the rear stage unit 20, and the peripheral unit 30 are configured to include at least separate CPUs, ROMs, RAMs, etc., and the functions of the respective units are separate. However, the function of each unit may be realized by a single middleware. This makes it possible to add an authentication function as a highly versatile middleware in the development of new models of gaming machines, facilitates horizontal deployment to other models, and requires only a small design change for each model. It can contribute to realization.

  In the pachinko gaming machine 1 according to the first to third embodiments, the main control unit 10 is generated by a random number generation circuit, a random number generation program, or the like as a predetermined data division method for generating individual test values. Although the value is determined as the number of divisions and predetermined data is divided into the determined number of divisions, the present invention is not limited to this. The main control unit 10 determines the amount of data constituting each data block for which individual test values are to be generated (hereinafter referred to as data amount), and the main control unit 10 stores predetermined data in a predetermined storage area. The data is divided by the determined amount of data. Then, the main control unit 10 performs a semi-group operation for each data block divided by the data amount, and generates individual test values for the number of divided data blocks for authenticating the main control unit 10. That is, the number of data blocks obtained by the division becomes the division number. As a method for determining the data amount, a method of referring to a value generated in another process of the main control unit 10 at a predetermined timing in addition to the random number generation circuit and the random number generation program and using the value as the data amount can be considered. .

  In this case, every time the main control unit 10 generates one individual test value, the main control unit 10 determines the amount of data used for the generation, and uses all of the predetermined data in the predetermined storage area of the main control unit 10, Until the generation of the individual test value is completed, the determination of the data amount and the generation of the individual test value are repeated. At this time, it is not known how many individual test values are generated (that is, how many divisions are made) until the individual test values are generated using all predetermined data in a predetermined storage area. In this way, the possibility of illegally stealing the number of divisions can be reduced by determining the amount of data used for generating the individual test value rather than determining the number of divisions. The main control unit 10 may determine the data amount used for generating the individual test value in advance, instead of determining the data amount every time one individual test value is generated. Further, the data amount used for generation of all individual test values may be made equal, and in this case, the number of divisions can be predicted when the data amount is determined.

  Further, in the pachinko gaming machine 1 according to the first to third embodiments, the main control unit 10 selects the packet information included in the synchronization code from two types of packet information, continuous packet information and intermittent packet information. However, the packet information may be selected from a plurality of types of packet information. The type of packet information is determined by the value of the correlation condition between packet information generated continuously (for example, the difference value of the basic value of packet information). The plurality of types of packet information are different types of packet information each having a different correlation. In this case, the main control unit 10 selects one of a plurality of types of packet information based on the number of divisions, and uses the selected packet information for the next generation of the synchronization code. The post-stage unit 20 or the peripheral unit 30 selects one of a plurality of types of expected operation authentication values, which are information indicating a correlation specific to the type of packet information, according to the operation authentication rule based on the number of connections and the switching information. The next operation authentication is performed using the selected operation authentication expected value.

  Further, the pachinko gaming machine 1 according to the first to third embodiments generates an individual test value using a predetermined half-group operation and performs an individual authentication process using a predetermined individual authentication expected value. It is not limited to. The main control unit 10 prepares a plurality of semi-group operations in advance, and performs one semi-group operation used to generate the next individual test value from the plurality of semi-group operations based on the number of divisions this time. The rear stage unit 20 or the peripheral unit 30 is configured to select the half group operation and the individual used in the next combination process based on the current number of connections corresponding to the switching of the half group operation in the main control unit 10. You may comprise so that an authentication expected value may be switched. Specifically, the main control unit 10 selects, for example, the next half group calculation different from the one used this time when the current division number is an odd number, and the next division number when the current division number is an even number. Select the same semigroup operation as used this time. In addition, when the number of couplings this time is an odd number, the rear-stage unit 20 or the peripheral unit 30 selects a half-group operation and an individual authentication expected value at the time of the next coupling process that are different from those used this time, If the number is an even number, the same half-group operation and individual authentication expected value used at the time of the next joining process are selected as those used this time. In this case, the first half group calculation is set in advance to use the same method between the main control unit 10 and the rear stage unit 20 or the peripheral unit 30. The number of divisions is a value that only the main control unit 10 can know, and the number of connections is a value that can be known to the rear stage unit 20 or the peripheral unit 30 only after successful individual authentication. Therefore, the fraudster cannot know the switching timing of the half group calculation in the main control unit 10 and the individual authentication expected value in the rear stage unit 20 or the peripheral unit 30. Thereby, the authentication intensity | strength with respect to the process between the main control part 10, the back | latter stage part 20, or the peripheral part 30 can be improved.

  In the pachinko gaming machine 1 according to the first to third embodiments, the individual authentication data and the operation authentication data may be added only when a predetermined control command is transmitted, for example, a predetermined control command. In this case, the main control unit 10 determines whether or not the control command is a predetermined control command, and generates individual authentication data and operation authentication data in the case of the predetermined control command. The main control unit 10 transmits an authentication data-added control signal in which the generated individual authentication data and operation authentication data are added to the control command to the subsequent stage unit 20 or the peripheral unit 30. Note that the main control unit 10 newly starts the individual authentication data and the operation even when the predetermined timing (for example, the transmission timing of the predetermined control command) is reached until all of the generated individual authentication data and operation authentication data are transmitted. A control signal with authentication data is transmitted without generating authentication data. As described above, by generating the individual authentication data and the operation authentication data only at the predetermined timing, it is possible to limit the number of generations of the authentication data, and to reduce the processing load due to the authentication processing.

  Here, the predetermined control command refers to various control commands for instructing the operation of the pachinko gaming machine 1 (for example, initialization operation, performance operation, customer waiting demonstration, etc.) while the pachinko gaming machine 1 is energized. A specific control command arbitrarily selected from the above. More specifically, the predetermined control command is, for example, a jackpot command transmitted while the jackpot state continues, a jackpot start command for starting the jackpot state processing, and a jackpot state process for ending the jackpot state processing. A jackpot end command, a jackpot reach command for causing the peripheral unit 30 to execute a process of reaching the jackpot, a power-on command for causing the peripheral unit 30 to execute a power-on process, and the peripheral unit 30 in a non-game state A customer waiting demo command for executing a demo display, a customer waiting demo stop command for stopping the demonstration display in the non-gaming state in the peripheral portion 30, and executing processing when the lottery result at the lottery is off in the peripheral portion 30 A command to make it off, called an open lottery of ordinary electric accessories (electric tulips) or so-called fake It refers to such that jackpot and the small hit command transmitted for the duration of the small contact state so as to open only for a short time a special electric combination thereof as well. As the predetermined control command, there are, for example, a power-off command, an unreach reach command, an unreach non-reach command, a round start command, and a round end command.

  In the pachinko gaming machine 1 configured as described above, at the timing of transmitting a predetermined control command, authentication processing is performed using authentication data for authenticating the validity of the main control unit 10. The processing load on the main control unit 10 and the peripheral unit 30 is increased only during the period when the control command data 301 of a predetermined control command is received. The rate at which the processing load increases can be suppressed.

  Further, since the authentication data is added only to the control command data of the predetermined control command, it is only necessary to add an authentication process related to the predetermined control command to the program executed by the peripheral unit 30. Accordingly, since it is not necessary to design a new timing for the entire program executed by the peripheral unit 30, the timing for adding the authentication function is compared with the case where the authentication data is added to the control command data of all control commands. Design, implementation of functions, verification of functions, etc. can be realized more easily and with less work man-hours.

  Further, only when the main control unit 10 transmits a predetermined control command to the peripheral unit 30, when at least one of the individual authentication data and the operation authentication data is added to the control command data, it is predetermined that the authentication process is performed. Since this is only at the time of transmission of the control command data of the control command, it is possible to suppress the rate at which the processing load on the main control unit 10 and the peripheral unit 30 increases due to the authentication process. When the predetermined control command is a jackpot command, the jackpot command is transmitted for each round of jackpot, so the authentication process is performed multiple times during a certain period in the jackpot state, improving the accuracy of the authentication process. be able to.

  Also, when the predetermined control command is a jackpot start command or jackpot end command, the jackpot start command or jackpot end command is a control command for starting or ending the jackpot state, and compared with other control commands, the transmission frequency Is low. Therefore, the possibility that the authentication data is extracted from the control signal can be reduced. Further, even if authentication data is extracted from the control signal, the number of samples that can be acquired is small, so that the risk that the authentication data is analyzed can be reduced.

  When the predetermined control command is a jackpot reach command, the jackpot reach is generated more frequently than the jackpot reach. Moreover, the occurrence timing of jackpot reach has randomness. Therefore, by performing the authentication process when transmitting the jackpot reach command data, the execution positions of the authentication process on the time axis are distributed. And the reliability of an authentication process can be improved by distributing the implementation position of the authentication process on a time axis in this way. This is because even if authentication data communication failure or authentication data tampering is performed for a certain period, authentication processing is performed at random time, so the possibility of avoiding communication failure and tampering may be avoided This is because of the increase.

  Further, when the predetermined control command is a power-on command, the power-on command is transmitted when the pachinko gaming machine 1 is initialized, such as when the pachinko gaming machine 1 is powered on or reset. The initialization process is classified into a process category different from the game (game progress) related process which is the main process of the pachinko gaming machine 1. Therefore, if the authentication process is incorporated during the initialization process as in the present invention, the rate of increase in the number of steps (man-hours) required for program design and testing is reduced compared to the case where the authentication process is incorporated during the game-related process. can do. That is, by incorporating the authentication process during the initialization process, it is possible to obtain development merit and quality control merit. Further, if authentication processing is incorporated during initialization processing, authentication processing is performed immediately after the pachinko gaming machine 1 is started, so that even if a fraud is performed after the game store is closed, the customer enters the store. Fraud can be detected before. Therefore, the risk of damage caused by fraud can be reduced.

  When the predetermined control command is a customer waiting demo command or a customer waiting demo stop command, the customer waiting demo command or the customer waiting demo stop command indicates that the pachinko gaming machine 1 is in a non-game state, that is, the main of the pachinko gaming machine 1 This is transmitted when the game (game progress) related process is not performed, so that an increase in processing load due to the authentication process does not affect the game related process. For this reason, even when the main control unit 10 and the peripheral unit 30 do not have a high processing capacity, or even in the pachinko gaming machine 1 with a large processing load of game-related processing, an authentication processing function can be added. . Further, since the customer waiting demo command and the customer waiting demo stop command are commands issued before the customer operates the pachinko gaming machine 1, the customer detects an illegal act before operating the pachinko gaming machine 1. Can do.

  Furthermore, when the predetermined control command is a loss command, “out of” occurs most frequently as a lottery result at the time of lottery, so that authentication data 303 is added to the control command when the loss command data is transmitted. The flow from the lottery to the authentication process can be regarded as a basic form of processing of the pachinko gaming machine 1. On the other hand, processing at the time of jackpot reach and jackpot is classified into special processing such as changing the presentation method for each model of pachinko gaming machine 1, but processing at the time of losing is different for each model of pachinko gaming machine 1 There are few differences. For this reason, if the authentication process is incorporated in the process at the time of disconnection as in the first embodiment, the main body of the pachinko gaming machine 1 can be reused for another model without making a major change in the flow of the authentication process. Is possible.

  Further, the peripheral unit 30 may add individual authentication data or operation authentication data to the control command only when a predetermined control command is transmitted to the subsequent unit 20. In this case, since the authentication process of the rear stage unit 20 is performed only when a predetermined control command is transmitted, the rate at which the processing load of the peripheral unit 30 increases due to the authentication process can be suppressed. Further, in this case, it is only necessary to add an authentication process related to a predetermined control command to the program executed by the rear stage unit 20. Therefore, since it is not necessary to design a new timing for the entire program executed by the latter stage unit 20, the timing for adding the authentication function as compared with the case where individual authentication data or operation authentication data is added to all control commands. Design, function implementation, function verification, etc. can be realized more easily and with less man-hours.

  In addition, in the pachinko gaming machine 1 according to the first to third embodiments, the main control unit 10 includes individual control command data and accompanying data in addition to a control signal with authentication data to which individual authentication data and operation authentication data are added. The control signal with individual authentication data to which only the authentication data is added, and the control signal with operation authentication data to which only the operation authentication data is added to the control command data and the accompanying data may be transmitted to the subsequent stage unit 20 or the peripheral unit 30, respectively. Good. Further, the post-stage unit 20 or the peripheral unit 30 may add various authentication results and various authentication data constituting the intermediate authentication information to different control signals and transmit them separately.

In addition, the pachinko gaming machine 1 according to the first to third embodiments has been described as adding the individual authentication data and the operation authentication data to the control command when transmitting the control command. However, the gaming machine according to the present invention is not limited thereto. It is not limited. The main control unit 10 may add authentication data to a data signal different from the control command and transmit it to the subsequent stage unit 20 or the peripheral unit 30. For example, a timing for transmitting / receiving authentication data between the main control unit 10 and the rear-stage unit 20 or the peripheral unit 30 is set in advance, for example, authentication data is added to an arbitrary data signal and transmitted every predetermined time Just keep it. Further, the main control unit 10 may output the data signal to which the authentication data is added so as to have a data structure different from the control command so that it can be understood.
Further, the main control unit 10 may transmit the authentication data itself as a data signal without adding the authentication data to the data signal.

Further, in each of the above embodiments, an example in which the present invention is applied to a pachinko gaming machine has been shown. The present invention can also be applied to other gaming machines such as a revolving type gaming machine such as a gaming machine or a slot machine. Even in these gaming machines, the same effects as those of the above-described embodiments can be obtained by configuring similarly to the above-described embodiments.
In addition, each of the above embodiments can utilize each other's technology as long as there is no particular contradiction or problem in the purpose, configuration, or the like.
