(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.

JP-A-2005-21330 JP 2002-210194 A JP 2008-279037 A

  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 that the above problem increases with the addition of the 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. tend to be diverse, 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.

  According to the present invention, it is possible to detect fraudulent acts due to replacement of a regular main control board and an unauthorized main control board of a gaming machine or malfunction of the gaming machine, and to reduce the processing load on the peripheral CPU.

  Specifically, according to the present invention, the main control unit adds the inspection value obtained by the inspection value generation unit using predetermined data stored in the data storage unit to the control command and transmits the control command to the intermediate unit. The intermediate unit 2 uses the operation value obtained by performing the binary operation using predetermined data stored in the data storage means of the main control unit and the inspection value added to the predetermined control command. The main control unit is authenticated based on whether or not the calculation result obtained by performing the term calculation matches. As a result, it is possible to detect the above-mentioned fraud and malfunction of the gaming machine, and it is possible to prevent the game store from being damaged due to an unreasonable amount of game media being paid out to the player.

  Further, according to the present invention, since the authentication process is executed only by the intermediate part, it is possible to suppress an increase in the processing load of the CPU constituting the peripheral part. For this reason, it is possible to prevent the occurrence of problems such as the processing speed of the peripheral portion being reduced and the display for production not being performed smoothly.

  Furthermore, according to the present invention, since the intermediate unit that executes the authentication process and the peripheral unit that performs the predetermined process are independent of each other, the authentication program and the predetermined process program are designed separately. be able to. This makes it easier to design the timing for adding the authentication function, implement the function, verify the function, etc., compared to the case where the authentication function is added to the peripheral processing that performs the predetermined process Can be realized. In addition, since the configuration of the authentication program and the predetermined processing program is relatively simple, it is easy to maintain consistency with other functions.

  Furthermore, according to the present invention, even if the predetermined processing is different for each gaming machine model, the authentication process can be shared, so that the program design for each gaming machine model is easy, Design time can be shortened and work efficiency can be improved.

  Furthermore, according to the present invention, when the authentication algorithm for authentication is changed, it is only necessary to change the authentication program in the intermediate part without changing the peripheral part for performing the predetermined processing, thereby reducing the number of authentication algorithms. The authentication algorithm can be changed by man-hours.

  Furthermore, according to the present invention, the main control unit divides predetermined data to generate individual test values, and performs processing related to operation authentication based on the number of divided data (number of divisions). The type of packet information to be generated in order to generate a synchronization code is selected. In addition, the intermediate unit generates a synchronization code during the process related to the operation authentication based on the number of authentication data (the number of combinations) subjected to the binary operation when the individual authentication to the main control unit is successful. The type of packet information that is recognized as being generated is identified. Since the number of divisions is a value that only the main control unit can know, and the number of connections is a value that the intermediate unit can know only after successful individual authentication, The type cannot be specified. For this reason, it is possible to prevent unauthorized persons from generating the synchronization code illegally, and to improve the strength of the authentication process between the main control unit and the intermediate unit. Can be detected, and execution of unauthorized control commands due to these can be prevented.

  Furthermore, according to the present invention, the intermediate unit verifies the operation order of the main control unit by using two types of operation test values of the synchronization code and the operation code. By performing the authentication process twice using two types of operation inspection values, the strength of the operation authentication process by the intermediate unit can be improved, and the operation order of the main control unit can be verified to verify the main control unit. The continuity of the operation can be authenticated, and for example, an unauthorized control board equipped with a signal switching circuit or the like can be detected.

<< 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 configuration of a gaming machine 1 according to Embodiment 1 of the present invention. This gaming machine 1 includes a main control unit 10, an intermediate 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, synchronization code generation means 14, and operation code generation means 15. 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 means 13 generates an individual test value used for authenticating the legitimacy (identity) of the main control unit 10 as an individual. 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 synchronization code generation unit 14 verifies the operation sequence of the main control unit 10 and controls it as one of operation inspection values for authenticating that the process (operation) by the main control unit 10 is continuously executed. A synchronization code including packet information generated when the command is transmitted is generated. The synchronization code is information for verifying that transmission of the control command by the main control unit 10 is continuously executed. In addition, the synchronization code generation unit 14 selects a synchronization code from 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 13). Selects the type of packet information used for generation. Note that the type of packet information is determined by the correlation between two pieces of continuous packet information of the selected packet information.

  The operation code generation means 15 is generated using a value that varies with a certain relationship in the processing performed by the main control unit 10 as one of the operation inspection values for authenticating the continuity of the operation of the main control unit 10. The For example, in a program executed by the main control unit 10, a number assigned in advance for each process for executing a predetermined function (hereinafter referred to as a function number) or the number of times authentication processing is executed in the main control unit 10 ( Hereinafter, the number of times of authentication).

  Then, the main control unit 10 converts the individual authentication data for the number of divisions obtained by performing the encryption processing on the individual inspection values for the generated number of divisions, and the operation inspection values composed of the synchronization code and the operation code. The operation authentication data obtained by performing the encryption process is added to the control command to be output and transmitted to the intermediate unit 20.

  On the other hand, the intermediate unit 20 includes a calculation value storage unit 21, an individual authentication unit 22, and an operation authentication unit 23. The calculated value storage means 21 is a calculated value obtained by performing a binary operation using predetermined data stored in the data storage means 11 constituting the main control unit 10 (hereinafter referred to as an individual authentication expected value). ) Is stored in advance. The individual authentication means 22 performs a binary operation satisfying the above-mentioned combination rule on the individual inspection value added to the control command and transmits the result of the calculation and the individual authentication value stored in the operation value storage means 21. The main control unit 10 is authenticated (individual authentication) based on whether or not the expected value matches.

  The operation authentication unit 23 authenticates (operation authentication) the continuity of the operation of the main control unit 10 using the operation inspection value (synchronization code and operation code). When performing the operation authentication of the main control unit 10 using the synchronization code, the operation authentication unit 23 is based on the number of individual test values (the number of connections) when the individual authentication by the individual authentication unit 22 is successful. The type of the packet information recognized as being generated when generating the synchronization code transmitted from 10 is identified, and the operation authentication is performed.

  Then, the intermediate unit 20 adds the authentication result obtained by the individual authentication unit 22 or the operation authentication unit 23 to the control command and transmits it to the peripheral unit 30. Thereby, the peripheral part 30 performs the process according to the authentication result added to the control command.

  FIG. 2 is a front view showing an external configuration of the pachinko gaming machine 1 which is one of the gaming machines according to Embodiment 1 of the present invention. FIG. 3 is a block diagram showing an electrical configuration of the pachinko gaming machine 1 shown in FIG.

  The pachinko gaming machine 1 according to the first embodiment includes a game board 101. An operation handle 113 is provided on the lower right side of the game board 101 in FIG. 2 and at the lower right side of the frame member 110 to be operated by the player and actuate the launcher 292 (see FIG. 3). The operation handle 113 has a shape protruding to the player side. The operation handle 113 includes a firing instruction member 114 that activates the launching portion 292 to launch a game ball. The firing instruction member 114 is provided on the outer peripheral portion of the operation handle 113 so as to rotate clockwise as viewed from the player. The firing unit 292 causes the game ball to be fired when the firing instruction member 114 is directly operated by the player. Although not described because it is a known technique, the operation handle 113 is provided with a sensor that detects that the player directly operates the firing instruction member 114.

  The game ball launched by the operation of the launch unit 292 rises between the rails 102 a and 102 b and reaches the upper position of the game board 101, and then falls within the game area 103. The game area 103 is provided with a plurality of nails (not shown), a windmill (not shown) that changes the falling direction of the game ball, and a entrance, so that the game ball falls in various directions. I try to let them. Here, the “ball entry” is a general term for a first start opening 105, a second start opening 120, a normal winning opening 107, a first large winning opening 109c, and a second large winning opening 129c, which will be described later.

  A symbol display unit 104 is disposed at a substantially central portion of the game board 101. The symbol display unit 104 includes a display such as a liquid crystal display (LCD) or a plasma display panel (PDP), for example. Below the symbol display unit 104, a first start port 105 capable of receiving a game ball driven toward the game area 103 is disposed. A second start port 120 is disposed below the first start port 105. When the pair of movable pieces (not shown) is in the closed state, the second starter port 120 is unable to accept the game ball or is difficult to accept, and when the pair of movable pieces is in the open state.

  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 shown in [1] to [7] below, but the encryption processing shown in [3] 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 to obtain individual test values for the number of divisions for authenticating the main control unit 10. Generate. Note that the same method is set in advance between the main control unit 10 and the intermediate unit 20 for the generation method of the individual test values (for example, the type of binary operation that satisfies the combining law used for generating the individual test values). You just have to.

“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 main control unit 10, adds the generated data to the control command, and transmits the data to the intermediate unit 20. 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. In addition, data for authenticating the continuity of the operation of the main control unit 10 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 encrypt the individual test value or the operation test value in the main control unit 10, and the individual authentication data or the operation authentication data is decrypted when the individual test value or the operation test value is extracted in the intermediate unit 20. Since there is no need to perform the authentication process, the process related to authentication can be simplified, and an increase in processing load can be suppressed.
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.

  When the individual control data 303 obtained by performing encryption processing on each individual test value is transmitted to the intermediate unit 20 in the main control unit 10, each individual test value that has not been subjected to any processing is transmitted. Compared with the case where it transmits to the intermediate part 20 as it is, possibility that each individual test value will be analyzed by a fraudulent person can be reduced. The main control unit 10 may perform different encryption processing on 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.

  Further, the main control unit 10 prepares a plurality of methods such as encryption processing in advance, and a plurality of encryption processing based on the current number of divisions (number of data blocks) determined in the processing [1]. One encryption process used for the next generation of individual authentication data may be selected from the list. 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.

(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. 4, the value “0xF2” and the individual authentication data from the third individual test value “0x32” are generated. 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, since the authentication is not successful, 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 Test Value The main control unit 10 adds the control command data and accompanying data to the intermediate unit 20 so as to authenticate the continuity of the operation of the main control unit 10 in the intermediate unit 20. Two types of codes, a synchronization code and an operation code, are generated as the operation inspection value and stored in an operation inspection value memory which is a predetermined storage area of the RAM 10c. The operation test value memory of the RAM 10c is divided into a synchronization code memory for storing a synchronization code and an operation code memory for storing an operation code. Hereinafter, generation of the synchronization code and the operation code will be described in detail.

{1} Generation of Synchronization Code The main control unit 10 is generated along with the operation having the continuity of the main control unit 10 in order to authenticate the continuity of the operation of the main control unit 10 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 the packet information is generated along with the transmission of the control command of the main control unit 10, and the correlation between the packet information generated at the generation timing according to the transmission timing of the continuous control command is The continuity of operation of the main control unit 10 is authenticated depending on whether or not a predetermined correlation is set in advance. 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 transmission of the control command, and packet information (at a specific interval with the transmission 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.
More 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 is generated intermittently at specific intervals. It is at least two (two times) packet information. For example, when the main control unit 10 can generate packet information every clock timing, the generation timing of intermittent packet information can be set as the generation timing of 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, the continuity of the operation of the main control unit 10 can be authenticated by obtaining the correlation between a plurality of pieces of packet information at successive generation timings.

  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, in the operation authentication in the intermediate unit 20 described later, when generating one synchronization code using one packet information so that the correlation between transmitted packet information can be confirmed, a plurality of synchronization codes are used. It is generated and transmitted to the intermediate unit 20 one or more times. 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. These also apply to the generation of operation codes described later.

  The main control unit 10 can select the type of packet information used for generating the synchronization code based on the number of divisions. More specifically, the main control unit 10 may select whether to generate a synchronization code using intermittent packet information or to generate a synchronization code using continuous packet information according to a predetermined agreement based on the number of divisions. it can. The predetermined agreement is shared between the main control unit 10 and the intermediate unit 20, and includes, for example, the following (Selection Example 1) and (Selection Example 2). FIG. 5 schematically shows a predetermined agreement as a packet information selection method in the main control unit 10.

(Selection example 1: number of divisions / remainder of X)
In selection example 1 shown in FIG. 5, the type of packet information used to generate the synchronization code is selected based on the remainder value obtained by dividing the value determined as the number of divisions by a predetermined specific value X. For example, if the specific value X = 3 and the number of divisions = 3, the remainder value = 0, and in the selection example 1 of FIG. 5, intermittent packet information is selected, and if the specific value X = 3 and the number of divisions = 4 The remainder value = 1, and in the selection example 1 in FIG. 5, continuous packet information is selected.

(Selection example 2: | absolute value of previous division number-current division number |)
In selection example 2 shown in FIG. 5, packet information used for generating a synchronization code is selected based on an absolute value obtained by subtracting the previously determined number of divisions from the currently determined number of divisions. For example, if the previous number of divisions = 3 and the current number of divisions = 5, the absolute value | −2 | = 2, and continuous packet information is selected in the selection example 2 in FIG.

  Other predetermined arrangements include, for example, a method in which packet information to be selected is determined for each division number, such as an intermittent packet in the case of division number 2, a continuous packet in the case of division number 3 or the like. There is a method of changing the type of packet information used for generating the synchronization code when the number is even, and continuously using the type of packet information currently used when the number of divisions is odd.

  Even when a signal switching circuit or the like is mounted on an unauthorized control unit by verifying the operation sequence of the main control unit 10 using the synchronization code, the operation sequence authenticated by the synchronization code is not continuous. It can be determined that the control command is transmitted from an unauthorized control unit other than the control command transmitted from the control unit 10, and unauthorized control can be detected.

  In addition, the main control unit 10 selects the type of packet information used for generating the synchronization code based on the value of the number of divisions that only the main control unit 10 knows, so that the fraudster can determine which type of synchronization code is generated. It can be prevented that the packet information is used. Thereby, it is possible to prevent the synchronization code from being illegally generated. Hereinafter, in the first embodiment, (selection example 1) shown in FIG. 5 is adopted as the predetermined agreement, and the specific value X is described as X = 3. The means for executing the process for generating the synchronization code can correspond to, for example, the synchronization code generation means 14 shown in FIG.

  In the first embodiment, along with the transmission of the control command of the main control unit 10, continuous packet information for generating packet information every time transmission is performed and the transmission of the control command of the main control unit 10 is performed. The synchronization code is generated using the two types of intermittent packet information that generates packet information at specific intervals instead of every transmission of the synchronization code. However, in the present invention, the generation timing of the synchronization code is not limited to this, and the synchronization code is generated. The code may be generated at a timing before the transmission 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.

{2} Generation of Operation Code In addition, the main control unit 10 recognizes the continuity of the operation of the main control unit 10 as one of the operation inspection values. And an operation code which is information for verifying the operation order of the control command transmission). The operation code is generated using a value that varies with a certain relationship such as a function number or the number of authentications. Hereinafter, a case where the operation code is generated using the function number or the number of authentications will be described. However, what the operation code is generated is determined in advance with the intermediate unit 20. The operation code may include a plurality of pieces of information for verifying the operation sequence of the main control unit 10 such as an operation code generated using both the function number and the number of authentications.

  First, a case where an operation code is generated using a function number will be described. In the main control unit 10, function numbers are assigned in advance without duplication for each process for executing a predetermined function in various programs to be executed (for example, jackpot commands). When the main control unit 10 executes the program to which the function number is assigned, the main control unit 10 acquires the function number every time a predetermined function is executed. The main control unit 10 stores the acquired function number as an operation code in an operation code memory, which is a predetermined storage area of the RAM 10c, in a state where the acquired order can be determined. For example, the main control unit 10 stores a plurality of acquired function numbers (operation codes) in the order of acquisition. The plurality of operation codes arranged and stored in the acquired order indicate the operation order when the main control unit 10 executes various programs.

  A specific example of how to assign function numbers will be described. The function number can be assigned to control commands generated in succession such as a jackpot reach command, a jackpot start command, and a subsequent jackpot command (for example, for 15 rounds). In this case, function number 1 is assigned to the jackpot reach command. Next, function number 2 is assigned to the jackpot start command. Next, function numbers 3 to 18 are assigned to each of the 15 round jackpot commands. In this way, continuity of the operation sequence of the main control unit 10 is increased by assigning consecutive function numbers to control commands that are generated continuously in time series and checking the continuity of the function numbers that are generated continuously. Can be verified. The function number may be assigned for each predetermined function of a program that is continuously executed, and the granularity of the predetermined function of the program is not particularly limited.

  Next, a case where an operation code is generated using the number of authentications will be described. The number of times of authentication is the total number of authentication processes since the power of the pachinko gaming machine 1 is turned on, and the authentication process is a general term for processes that combine the individual authentication process and the operation authentication process. That is, the number of times of authentication is the number of times that the main control unit 10 has performed an individual test value generation process. The main control unit 10 stores the number of times of authentication as an operation code in an operation code memory which is a predetermined storage area of the RAM 10c. The main control unit 10 adds 1 to the value of the number of times of authentication stored in the RAM 10c every time the authentication process is performed, generates a new value of the number of times of authentication, that is, a new operation code, and stores this operation code in the RAM 10c. To do. Note that the means for executing the process for generating the operation code can correspond to, for example, the operation code generation means 15 shown in FIG.

[5] Generation of operation authentication data The main control unit 10 generates each synchronization code generated by the process {1} of [4] and each operation code generated by the process {2} of [4]. The encryption process may be performed. Here, as the encryption method, the same method as that used when generating the individual authentication data can be considered. The encryption processing performed when generating the individual authentication data, the encryption processing applied to each synchronization code, and the encryption processing applied to each operation code may be the same encryption processing or different encryption processing. Good. Different encryption processing may be performed for each synchronization code or operation code. The same applies to processing related to intermediate processing information 305 in the intermediate unit 20 described later.

  Here, when generating a plurality of operation codes using function numbers in the generation of operation codes, the main control unit 10 maintains information on the order in which the plurality of operation codes are generated, that is, the operation order of the main control unit 10. As it is, a plurality of operation authentication data are generated together with the synchronization code. For example, the main control unit 10 performs an encryption process on each of the operation codes together with the synchronization code while maintaining the arrangement of the plurality of function numbers (operation codes) arranged in the acquired order, and performs a plurality of operations. Generate authentication data. Therefore, like the plurality of operation codes, the plurality of arranged operation authentication data indicates the operation order when the main control unit 10 executes various programs.

  When each synchronization code and each operation code subjected to encryption processing in the main control unit 10 are transmitted to the intermediate unit 20, each synchronization code and each operation code that has not been subjected to any processing are directly sent to the intermediate unit 20. Compared to the case of transmission, the possibility that each synchronization code and each operation code are analyzed by an unauthorized person can be reduced.

  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. Similarly, encryption processing may be performed on data that is a combination of at least one of the control command data transmitted along with the operation code and the accompanying data and the operation code. In addition, the synchronization code and the operation code may include control command data and accompanying data transmitted together with the synchronization code and the operation code. In addition, a predetermined processing process may be further added to the encryption process as in the case of generating individual authentication data.

  The main control unit 10 prepares a plurality of methods such as encryption processing in advance, and a plurality of encryption processing based on the current number of divisions (number of data blocks) determined in the process [1]. One encryption process to be used for generating the next operation authentication data may be selected from the list. 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.

[6] Data addition to control signal The main control unit 10 adds individual authentication data and operation authentication data to the control command data and accompanying data transmitted to the effect control unit 203 via the intermediate unit 20 to generate authentication data. A control signal is generated. 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 intermediate unit 20.

  Here, an example of a data format of a control signal transmitted from the main control unit 10 to the intermediate unit 20 will be described with reference to a schematic diagram shown in FIG. A plurality of operation authentication data are generated when an operation inspection value is generated using a function number as an operation code, but only one operation authentication data is shown in FIG. 6 for simplicity. FIG. 6 (1) shows a normal control signal 300 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 intermediate unit 20, the main control unit 10 stores 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. A control signal with authentication data 310 is generated and output. The operation authentication data 304 includes a synchronization code 304a and an operation code 304b.

  Although not shown in FIG. 6, the normal control signal 300 and the control signal with authentication data 310 include BCC (Block Check Character) and the like, as in the case of control signals 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 same applies to the normal control signal 320 and the control signals 321, 322, and 323 with intermediate processing information shown in FIG.

  The control signal with authentication data is a control signal with authentication data arranged in the order of control command data 301, accompanying data 302, individual authentication data 303, synchronization code 304a and operation code 304b as shown in FIG. 6 (2). Not limited to 310, these 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. Further, the synchronization code 304a and the operation code 304b may be arranged reversely or separately.

  In this way, by including the individual authentication data 303 and the operation authentication data 304 in the control signal, the main control unit 10 and the effect control unit 203 are compared with the case where the individual authentication data 303 or the operation authentication data 304 is transmitted alone. Increase in communication load between the two can be suppressed. In addition, by including the individual authentication data 303 and the operation authentication data 304 in the control signal, the individual authentication data 303 and the operation authentication from the communication data are compared with the case where the individual authentication data 303 and the operation authentication data 304 are transmitted alone. The risk that the data 304 is extracted and analyzed can be reduced.

<Intermediate part>
The intermediate unit 20 includes a CPU 20a, a ROM 20b, a RAM 20c, and the like. The CPU 20a executes processing (hereinafter referred to as intermediate processing) based on a program (program code) stored in advance in the ROM 20b. The ROM 20b performs a plurality of half-group operations using a program code for the CPU 20a to execute intermediate processing and a predetermined program code to be divided that is stored in advance in the ROM 10b constituting the main control unit 10. A plurality of expected values for individual authentication obtained in advance are stored in advance. Among the storage areas of the ROM 20b, the storage area in which the plurality of expected values for individual authentication are stored in advance can correspond to, for example, the calculated value storage means 21 shown in FIG. The RAM 20c functions as a work area for calculations performed when the CPU 20a executes intermediate processing.

In the first embodiment, this intermediate processing is as follows [1] to [7].
[1] Reception of Control Signal The intermediate unit 20 receives a normal control signal consisting only of the control command data 301 and the accompanying data 302 from the main control unit 10, or the control command data 301, the accompanying data 302, the individual authentication data 303, and the operation. A control signal with authentication data comprising authentication data 304 (synchronization code 304a and operation code 304b) is received. In addition, the intermediate | middle part 20 transmits to the production | presentation control part 203 as it is, when a normal control signal is received.

[2] Extraction of Individual Test Value and Operation Test Value The intermediate unit 20 extracts the individual authentication data 303 and the operation authentication data 304 (synchronization code 304a and operation code 304b) from the control signal with authentication data. Next, the intermediate unit 20 applies a decryption process corresponding to the encryption process used when generating the individual authentication data to the extracted individual authentication data, and extracts an individual test value. The intermediate unit 20 stores the extracted individual test value in the individual test value memory, which is a predetermined storage area of the RAM 20c. Further, the intermediate unit 20 extracts the synchronization code 304a and the operation code 304b from the extracted operation authentication data 304, and stores them in a synchronization code memory and an operation code memory, which are predetermined storage areas of the RAM 20c. Note that when the main control unit 10 performs encryption processing on the synchronization code 304a and the operation code 304b, the intermediate unit 20 extracts the synchronization code 304a and operation extracted from the decryption processing corresponding to the applied encryption processing. It is applied to the code 304b.

  In the first embodiment, an operation test value memory of the RAM 10c used when generating the operation test value of the main control unit 10, and an operation test value memory of the RAM 20c used when extracting the operation test value of the intermediate unit 20 Can be identified without any particular confusion. Henceforth, the term “memory for operation test values” will be used without distinction between the two unless otherwise specified. The same applies to the synchronization code memory and operation code memory.

[3] Individual authentication The intermediate unit 20 performs a semi-group operation on all the individual test values stored in the individual test value memory in the order shown below, so that the main control unit 10 is authorized. An individual authentication process is performed to authenticate the validity of the main control unit 10 as an individual (hereinafter simply referred to as validity) by authenticating the individual of the main control unit 10 as to whether or not it is a main control unit.
The {1} intermediate unit 20 performs a half-group operation (hereinafter referred to as a combining process) using all the individual test values stored in the individual test value memory.
{2} The intermediate unit 20 reads an expected value for individual authentication stored in advance from a predetermined storage area of the ROM 20b.

The {3} intermediate unit 20 determines whether or not the calculation result in the process {1} (hereinafter referred to as a combined result) matches the expected value for individual authentication read out in the process {2} (hereinafter referred to as “following result”). , Referred to as matching process).
The intermediate unit 20 determines that the individual authentication is successful when the combined result matches the expected value for individual authentication.
Since the semi-group operation satisfies the above-mentioned combination rule, the expectation for individual authentication that is the result obtained by performing the semi-group operation on all the predetermined program codes stored in advance in the ROM 10b of the main control unit 10 The 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 intermediate unit 20 authenticates the validity of the main control unit 10.
On the other hand, if the combined result and the expected value for individual authentication do not match, the intermediate unit 20 determines that the individual authentication has not succeeded.

    If the individual authentication is successful in the processing of {4} {3}, the intermediate unit 20 generates an individual authentication result indicating that the individual authentication is successful, and stores all the individual test value memories stored in the RAM 20c. Clear individual test values.

If the individual authentication is not successful in the process of {5} {3}, the intermediate unit 20 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} When the number of received individual authentication data is less than the predetermined number, the intermediate unit 20 determines that the individual authentication is not yet possible and can replace the individual authentication result with the authentication intermediate data, 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 equal to or greater than the predetermined number, the intermediate 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.

(Calculation example of expected value generation for individual authentication)
A method for generating the expected value for individual authentication will be described with reference to FIG.
The intermediate unit 20 holds a value obtained by performing a semi-group operation on the entire predetermined program code to be divided stored in the program code storage area 400 as an expected value for individual authentication. For example, the expected value for individual authentication in the case of method A is “0x4E” which is the sum of “0x01” to “0x0C”. Further, the expected value for individual authentication in the case of method B is “0x0C” which is an exclusive OR of “0x01” to “0x0C”. The intermediate unit 20 holds the same number of expected values for individual authentication as the number of half-group operations that are individual test value generation methods by the main control unit 10.

  The expected value for individual authentication used by the intermediate unit 20 for collation may be stored in advance in a predetermined storage area of the ROM 20b that configures the intermediate unit 20 at the time of manufacture, for example. However, the present invention is not limited to this. It is good also as transmitting to the intermediate | middle part 20. Examples of 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). The individual authentication expected value calculation unit may transmit the stored individual authentication expected value to the intermediate unit 20. Further, a coefficient necessary for calculating the expected value for individual authentication may be transmitted from an external device to the intermediate unit 20 or the expected value calculation unit for individual authentication via an external connection interface (not shown). . As described above, if the expected value for individual authentication is not stored in advance in the predetermined storage area of the ROM 20b constituting the intermediate unit 20, the individual test value is changed afterwards. It becomes possible to do.

[4] Operation Authentication The intermediate unit 20 uses the synchronization code 304a and the operation code 304b, which are operation inspection values extracted from the operation authentication data 304, to continue the operation of the main control unit 10 in the following order. Authenticate. The intermediate unit 20 specifies the number of individual test values (the number of connections) that are the targets of the combination process when the individual authentication is successful prior to the operation authentication.

Operation Authentication Using {1} Synchronization Code The intermediate unit 20 verifies the operation order of the main control unit 10 using the synchronization code 304a stored in the synchronization code memory. The synchronization code 304a includes at least one of a plurality of pieces of packet information generated at a predetermined generation timing. The intermediate unit 20 can determine whether or not a predetermined correlation according to the type of packet information specified in advance is maintained between the pieces of packet information by obtaining a difference between the plurality of pieces of packet information. .

{1-1} The intermediate unit 20 specifies the type of packet information recognized as being generated when the main control unit 10 generates the synchronization code, according to a predetermined agreement based on the number of combinations. The predetermined agreement is the same as the predetermined agreement used by the main control unit 10 to select the type of packet information used when generating the synchronization code. In the first embodiment, the above selection example 1 is adopted as a predetermined agreement. In the case of the selection example 1, the intermediate unit 20 is configured to divide the number of connections when the individual authentication is successful by a specific value X (here, X = 3) determined in advance with the main control unit 10. Based on the remainder value, the type of packet information is specified. For example, if the specific value X = 3 and the number of connections = 3, the remainder value = 0, which is intermittent packet information.
The {1-2} intermediate unit 20 obtains a difference between the packet information generated at a certain timing and the packet information generated at a timing when a predetermined generation interval has elapsed from this packet information, and this difference is calculated as {1 -1}, it is verified whether or not it has a predetermined correlation according to the type of packet information specified.

{1-3} If the difference between the packet information has a predetermined correlation, the intermediate unit 20 determines that the main control unit 10 is performing the control command transmission process in the correct operation order, and the main control It is determined that the operation authentication using the synchronization code for the unit 10 is successful. When the operation authentication is successful, the intermediate unit 20 generates an operation authentication result indicating that the operation authentication is successful.
{1-4} If the difference between the packet information does not have a predetermined correlation, the intermediate unit 20 does not perform the control command transmission processing in the correct operation order by the main control unit 10, and the illegal control command It is determined that the transmission process is being performed, and it is determined that the operation authentication using the synchronization code for the main control unit 10 has not succeeded. If the operation authentication is not successful, the intermediate unit 20 generates an operation authentication result indicating that the operation authentication is unsuccessful.

  When the main control unit 10 performs the encryption process on the synchronization code, the intermediate unit 20 performs the decryption process according to the content of the encryption process of the main control unit 10 to obtain the synchronization code. If the synchronization code indicates that the operation of the main control unit 10 is in the correct operation order, the operation of the main control unit 10 is authenticated as being continuous. When the intermediate unit 20 directly receives the synchronization code, the intermediate unit 20 authenticates the continuity of the operation of the main control unit 10 using the synchronization code.

(Calculation example of operation authentication using synchronization code)
Hereinafter, a calculation example of the operation authentication using the synchronization code 304a in the intermediate unit 20 will be described. The intermediate unit 20 verifies the synchronization state from the 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 (Authentication success condition) is “+2”. The inspection value of packet 1 transmitted from the main control unit 10 remains 0x03 as the basic value, and the inspection value of packet 2 becomes packet 1 + packet 2, that is, 0x03 + 0x05, and “0x08” is transmitted.

  Then, the packet 1 received by the intermediate 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 correlation value is 0x02. Since this value satisfies the correlation condition (which is +2) between the basic value of packet 1 and the basic value of packet 2, it is determined that the operation authentication is successful. After the operation authentication is successful, the synchronization code stored in the synchronization code memory of the RAM 20c is deleted.

  In the arithmetic processing using packet 1 and packet 2, the number of digits may be adjusted so that the arithmetic result does not overflow, or the basic values of packet 1 and packet 2 are selected within a numerical range that does not overflow. Alternatively, 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 the correlation change rule as described above is applied, the main control unit 10 and the intermediate unit 20 share in advance, or a means or process for notifying is prepared.

  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.

Operation Authentication Using {2} Operation Code The intermediate unit 20 verifies the operation sequence of the main control unit 10 using the operation code 304b stored in the operation code memory. The intermediate unit 20 uses the operation code generation method type (function number) as information for verifying whether the operation code generated by the main control unit 10 is generated while maintaining a predetermined relationship in time series. And the like using the number of times of authentication and the number of times of authentication, etc.) are stored. The expected value for the operation code corresponding to the operation code using the function number is data formed by associating a plurality of operation codes so that the operation order of the main control unit 10 can be determined, for example, a plurality of operation codes. A data table arranged in the order indicating the operation order of the main control unit 10.

  The expected value for the operation code corresponding to the operation code using the number of authentications is a value indicating the number of authentications. In this case, the intermediate unit 20 updates the expected value for the action code every time the action authentication process is performed. Specifically, like the main control unit 10, the intermediate unit 20 increments the value of the expected value for the operation code (number of times of authentication) stored in the RAM 20 c every time the operation authentication process is performed, and performs a new operation. Stored as expected value for code (number of authentications). In the following, the operation authentication when the operation code is generated using the function number or the number of times of authentication will be described. However, what the operation code is generated using is determined in advance with the main control unit 10. Has been.

{2-1} When an operation code is generated using a function number, a plurality of operations using a plurality of operation codes 304b read from the operation code memory and a data table as an expected value for the operation code A verification process is performed to determine whether the authentication data is arranged in a regular order. As a result of the collation processing, when a plurality of operation authentication data are arranged in a regular order, the intermediate unit 20 determines that the operation authentication is successful. On the other hand, when the plurality of operation authentication data are not arranged in the regular order, the intermediate unit 20 determines that the operation authentication has not been successful.
{2-2} If the operation code is generated using the number of authentications, whether or not the plurality of operation codes 304b read from the operation code memory matches the number of authentications as the expected value for the operation code. The collation process to judge is performed. As a result of the collation processing, when the operation code matches the expected value for the operation code, the intermediate unit 20 determines that the operation authentication has succeeded. On the other hand, if the motion code does not match the expected value for the motion code, the intermediate unit 20 determines that the motion authentication has not been successful. Then, the intermediate unit 20 updates the expected value for operation code indicating the number of times of authentication.
{2-3} When the operation authentication is successful in the processes {2-1} and {2-2}, the intermediate unit 20 generates an authentication result indicating that the operation authentication is successful, and performs the operation authentication. If not successful, the intermediate unit 20 generates an authentication result indicating that the operation authentication has not succeeded.

  When the main control unit 10 performs a predetermined calculation on the synchronization code and the operation code, the intermediate unit 20 performs a predetermined calculation according to the content of the calculation process of the main control unit 10 to perform the synchronization code and operation. Get the code. If the synchronization code and the operation code are operation inspection values indicating that the operation of the main control unit 10 is performed in the correct order, it is determined that the continuity of the operation of the main control unit 10 is ensured. To do. When the intermediate unit 20 directly receives the synchronization code and the operation code, the intermediate unit 20 authenticates the continuity of the operation of the main control unit 10 using the synchronization code and the operation code. In the following description of the first embodiment, it is assumed that the operation code is generated using the function number.

[5] Generation of intermediate processing information The intermediate unit 20 generates individual authentication data in the main control unit 10 for the individual authentication process [3], the authentication result obtained by the operation authentication process [4], or the authentication result. Information that has been subjected to encryption processing in the same manner as when it is generated is generated as intermediate processing information. If the individual authentication process [3] and the operation authentication process [4] are successful, the intermediate unit 20 determines that the authentication of the main control unit 10 is successful and generates intermediate process information indicating the successful authentication. To do. The intermediate unit 20 determines that the authentication of the main control unit 10 has not succeeded when either of the individual authentication process [3] or the operation authentication process [4] is unsuccessful. Generate intermediate processing information indicating success. Hereinafter, the individual authentication process and the operation authentication process are also referred to as an authentication process.

(Calculation example of intermediate processing information generation)
An example of calculation for generating intermediate processing information is shown below.
The intermediate unit 20 generates 1-byte long random numbers (range “0x00” to “0xFF”) with 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 the authentication is successful, the intermediate unit 20 sets the data “0x4B” having the value of the least significant bit of the random number “0x4B” generated by the uniform random number as “1” as the intermediate processing information 305. On the other hand, if the authentication is not successful, the intermediate unit 20 sets the data “0x4A” having the value of the least significant bit of the random number “0x4B” generated by the uniform random number as “0” as the intermediate processing information 305.

[6] Generation of control signal with intermediate processing information The intermediate unit 20 adds intermediate processing information to a normal control signal including control command data 301 and accompanying data 302 to generate a control signal with intermediate processing information.

[7] Transmission of control signal with intermediate processing information The intermediate unit 20 transmits a control signal with intermediate processing information to the effect control unit 203. Details of these intermediate processes (the processes [1] to [7]) will be described later. Further, the means for executing the individual authentication process and the action authentication process can correspond to, for example, the individual authentication means 22 and the action authentication means 23 shown in FIG.

  Here, an example of a data format of a control signal transmitted from the intermediate unit 20 to the effect control unit 203 will be described with reference to a schematic diagram shown in FIG. When the normal control signal 300 shown in FIG. 6 (1) is transmitted from the main control unit 10, the intermediate unit 20 includes control command data 301 and accompanying data 302 as shown in FIG. 7 (1). The normal control signal 320 is transmitted to the effect control unit 203 as it is. On the other hand, for example, when control signals with authentication data 310 to 312 shown in FIGS. 6 (2) to (4) are transmitted from the main control unit 10, the intermediate unit 20 is obtained from the individual authentication data 303. Intermediate processing such as authentication using each individual test value is performed to generate intermediate processing information 305, for example, control signals 321 to 323 with intermediate processing information shown in FIGS. 7 (2) to (4) are generated. And transmitted to the effect control unit 203.

  In this way, by including the intermediate processing information 305 in the control signal, an increase in the communication load between the intermediate unit 20 and the effect control unit 203 can be suppressed as compared with the case where the intermediate processing information 305 is transmitted alone. it can. Also, by including the intermediate processing information 305 in the control signal, the risk that the intermediate processing information 305 is extracted and analyzed from the communication data is reduced compared to the case where the intermediate processing information 305 is transmitted alone. be able to.

  Further, the intermediate processing information 305 may be added only to a predetermined control command. In this case, it is only necessary to add an authentication process related to a predetermined control command to the program executed by the effect control unit 203. Accordingly, since it is not necessary to design a new timing for the entire program executed by the effect control unit 203, the timing design for adding the authentication function is compared with the case where the intermediate processing information 305 is added to all the control commands. Implementation of functions, verification of functions, etc. can be realized more easily and with less work man-hours.

<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 effects during the game, and based on a control command transmitted from the main control unit 10 via the intermediate unit 20 based on a program (program code) stored in advance in the ROM 203b. And effect processing. The ROM 203b stores in advance a program code for the CPU 203a to execute a lottery and a production process of production and past production patterns. The RAM 203c functions as a work area for data and the like in arithmetic processing performed when the CPU 203a executes lottery and effect processing of effects. 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 via the intermediate unit 20, the effect control unit 203 performs a lottery based on the control command, and produces an effect background pattern, a reach effect pattern, and an appearance character. And the like are controlled, and 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 outlined above, the effect control unit 203 executes the following processing related to authentication based on a program stored in advance in the ROM 203b when receiving a control signal with intermediate processing information. .

  The effect control unit 203 extracts the intermediate process information from the control signal with intermediate process information, performs a decoding process on the intermediate process information, and extracts an authentication result. The effect control unit 203 performs processing based on the control command when the authentication result indicates successful authentication. When the authentication result indicates unsuccessful authentication, a notification to that effect is made.

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 intermediate unit 20, the production control unit 203, the prize ball control unit 204, and the lamp control unit 205 configured as described above are different printed boards (for example, the main control unit 10 is a main control board, The intermediate 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 mounted on a prize ball control board, and the lamp control unit 205 is mounted 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 intermediate 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 (control command data) indicating the control command”. 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 intermediate unit 20 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. As the initial setting process, the main control unit 10 sets, for example, a predetermined value for the stack pointer, and waits for the intermediate unit 20, the effect 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 intermediate unit 20 and the prize ball control unit 204, and then proceeds to step S3. When receiving the power-on command, the intermediate unit 20 transmits the power-on command to the effect control unit 203. 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 controls the production via the intermediate unit 20 and the intermediate unit 20. Control command transmitted to the unit 203 and the prize ball control unit 204, and control for transmitting initial control information for controlling a game at the time of start-up after power-on, for example, control mode, backup data, etc. A command 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 refers to 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 intermediate unit 20, and then proceeds to step S7. When receiving the customer waiting demo command, the intermediate unit 20 transmits the customer waiting demo command to the effect control unit 203. 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. When a game ball entering the mouth 120 is detected, the main control unit 10 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 entry of the game ball into the second starting port 120 is not detected, the main control unit 10 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 causes the intermediate unit 20 to receive a jackpot including control data (accompanying data) such as, for example, a jackpot type code (whether it is a normal hit or a probability fluctuation), reach, symbol variation time, and the like. After transmitting the reach command (design variation command), the process proceeds to step S14. When the jackpot reach command (symbol variation command) is received, the intermediate unit 20 transmits the jackpot reach command (symbol variation command) to the effect control unit 203. 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 intermediate unit 20, and then proceeds to step S16. When receiving the symbol stop command, the intermediate unit 20 transmits the symbol stop command to the effect control unit 203. In step S16, the main control unit 10 transmits a jackpot start command to the intermediate unit 20, and then proceeds to step S17. When the jackpot start command is received, the intermediate unit 20 transmits the jackpot start command to the effect control unit 203. In step S17, the main control unit 10 sequentially transmits to the intermediate unit 20 commands corresponding to each of the big hits (big hit command), and after completing the transmission of the big hit command for all rounds, the main control unit 10 proceeds to step S18. When the jackpot command corresponding to each round is sequentially received, the intermediate unit 20 sequentially transmits the jackpot command corresponding to each round to the effect control unit 203. In step S18, the main control unit 10 transmits a jackpot end command to the intermediate unit 20, and then proceeds to step S22. When receiving the jackpot end command, the intermediate unit 20 transmits the jackpot end command to the effect control unit 203.

  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 “out-of-reach command (design variation command)”. ”Is transmitted to the intermediate unit 20, and then the process proceeds to step S20. When receiving the outlier reach command or the outlier command, the intermediate unit 20 transmits the control command (design variation command) to the effect control unit 203.

  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 intermediate unit 20, and then proceeds to step S22. When receiving the symbol stop command, the intermediate unit 20 transmits the symbol stop command to the effect control unit 203.

  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 a termination process command to the intermediate unit 20 and then terminates a series of processes. When the end process command is received, the intermediate unit 20 transmits the end process command to the effect control unit 203.

  Here, FIG. 10 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. 10 (1) is transmitted at random. Also, the jackpot start command shown in FIG. 10 (2) is transmitted only once when shifting to the jackpot state when a jackpot has actually occurred. Furthermore, the jackpot command shown in FIG. 10 (3) is continuously transmitted for each round after shifting to the jackpot state. Also, the jackpot end command shown in FIG. 10 (4) is transmitted only once when all rounds of the jackpot state are completed and the normal state is entered.

  Next, processing by the effect control unit 203 will be described. In the following, regarding the process of the effect control unit 203 at the time of symbol variation (when a jackpot reach command (see step S13 shown in FIG. 9) or a loss reach command (see step S19 shown in FIG. 9) is received) and a jackpot reach command. 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 sends either a jackpot reach command (see step S13 shown in FIG. 9) or a miss reach command (see step S19 shown in FIG. 9), which is a symbol variation command, from the main control unit 10 through the intermediate unit 20. Is determined (see step S31 in FIG. 11). 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. 9) is received from the main control unit 10 via the intermediate unit 20. 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. 9) is received from the main control unit 10 via the intermediate unit 20 (see step S41 in FIG. 12). 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. 9) is received from the main control unit 10 via the intermediate unit 20. 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 | generation 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 a jackpot end command (see step S18 shown in FIG. 9) is received from the main control unit 10 via the intermediate unit 20. 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. 11) has been received from the effect control unit 203 (see step S51 in FIG. 13). 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. 11) 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 gaming machine 1 according to the first embodiment shown in FIG. 1 includes effect control means having the function of the effect control section 203, prize ball control means having the function of the prize ball control section 204, and lamp control. Lamp control means having the function of the 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-described fraud and noise, in the pachinko gaming machine 1 according to the first embodiment, an intermediate unit 20 is provided between the main control unit 10 and the effect control unit 203. Provided.
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. Data is added to the control command and transmitted to the intermediate unit 20.

  The intermediate unit 20 uses the individual test values obtained from the individual authentication data received from the main control unit 10 to authenticate whether the main control unit 10 is a regular main control unit. Further, the intermediate unit 20 authenticates whether the operation sequence of the main control unit 10 is correct and whether the control signal is a correct control signal by using each operation inspection value (synchronization code and operation code) from the operation authentication data. Do. Next, the intermediate unit 20 transmits to the effect control unit 203 intermediate process information obtained by performing an encryption process on the authentication result obtained by the authentication process. Then, the effect control unit 203 performs processing according to the authentication result obtained from the intermediate processing information received from the intermediate unit 20. In this way, the authentication process is performed with the intermediate unit 20 as the authenticator and the main control unit 10 as the person to be authenticated, and the validity of the individual of the main control unit 10 and the continuity of the control command transmitted from the main control unit 10 are increased. Certify. 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 also be reduced.

  Hereinafter, processing related to authentication performed between the main control unit 10, the intermediate unit 20, and the peripheral unit 30 will be described. Hereinafter, processing related to authentication between the main control unit 10 and the intermediate unit 20 will be described with reference to the flowcharts shown in FIGS. 14 and 15, but authentication between the main control unit 10 and the prize ball control unit 204 will be described. The processing related to is performed in the same procedure.

  FIG. 14 is a flowchart illustrating a procedure of control signal transmission processing 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 for generating the synchronization code based on the number of divisions determined in step S63 (step S66). Specifically, either intermittent packet information or continuous packet information is selected. Then, the selected packet information is generated, and a synchronization code is generated based on the packet information (step S67). Note that step S66 and step S67 are interchanged to generate two synchronization codes using both intermittent packet information and continuous packet information, and select which synchronization code is used later. May be. Further, the main control unit 10 generates an operation code using the function number (step S68).

  Subsequently, the main control unit 10 adds the individual test value (individual authentication data), the synchronization code and the operation code (operation authentication data) to the control command data (step S69), and sends a control signal with authentication data to the peripheral part. Transmit (step S70). The control signal with authentication data may be transmitted continuously, or may be mixed with a normal control signal and transmitted. Further, the transmission order of the authentication data is also arbitrary. The main control unit 10 returns to step S70 and repeats transmission of the control signal with authentication data until all authentication data (individual authentication data and operation authentication data) is transmitted (step S71: NO). When there is untransmitted authentication data among the generated authentication data (step S71: NO), the main control unit 10 does not generate new authentication data, and always returns to step S70 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. Then, when all the authentication data is transmitted (step S71: YES), the processing according to this flowchart is terminated.

  Next, the authentication process of the main control unit 10 by the intermediate unit 20 will be described. FIG. 15 is a flowchart showing a procedure of authentication processing of the main control unit 10 by the intermediate unit 20. First, the intermediate unit 20 determines whether or not a control signal as shown in FIG. 5 transmitted from the main control unit 10 has been received (step S81). If the determination result is “NO”, the intermediate unit 20 repeats the determination. And if the control signal transmitted from the main control part 10 is received (step S81: YES), the intermediate part 20 will progress to step S82.

  In step S82, the intermediate unit 20 determines whether or not each authentication data is included in the received control signal. When each authentication data is included in the received control signal (step S82: YES), the intermediate unit 20 proceeds to step S83. Here, the determination as to 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, or whether the control command data 301 or the accompanying information is included in the control signal. This is performed by determining whether or not any bit constituting the data 302 or separately provided identification data (not shown) indicates that each authentication data is included. In the process of step S82, the intermediate unit 20 does not determine whether each authentication data is included in the received control signal, but the control command data 301 included in the control signal indicates that the predetermined control command is included. It may be determined whether it is control command data.

  When each authentication data is included in the received control signal (step S82: YES), that is, when the received control signal is a control signal with authentication data, the intermediate unit 20 is included in the received control signal with authentication data. The individual authentication data is extracted and the decryption process is performed to obtain the individual test value, and the operation authentication data included in the control signal with the authentication data is extracted and the decryption process is performed to obtain the synchronization code and An operation code is acquired (step S83).

  The intermediate unit 20 stores the acquired individual test value in the individual test value memory, the synchronization code in the synchronization code memory, and the operation code in the operation code memory (step S84). Next, the intermediate unit 20 performs a semi-group operation (joining process) on all the individual test values in the individual test value memory (step S85). If there is one test value in the individual test value memory, the process proceeds to step S86 without performing the combining process.

  Then, the intermediate unit 20 collates the result of the combination process (combination result) with the held expected value for individual authentication, and determines whether the combined result matches the expected value for individual authentication. (Step S86). If the combined result matches the expected value for individual authentication (step S86: YES), the intermediate unit 20 makes the individual authentication of the main control unit 10 successful (step S87). The intermediate unit 20 specifies the number of connections based on the authentication result (step S88).

  Subsequently, the intermediate unit 20 specifies the type of packet information used for generating the synchronization code based on the number of combinations (step S89). Then, operation authentication using the synchronization code is performed by a method corresponding to the packet information specified in step S89 (step S90). The operation authentication using the synchronization code is performed by determining whether or not the correlation of the packet information included in the synchronization code is a predetermined correlation according to the type of the packet information. When the operation authentication using the synchronization code is successful (step S91: YES), the intermediate unit 20 performs the operation authentication using the operation code (step S92). The operation authentication using the synchronization code and the operation authentication using the operation code may be switched in order.

  If the operation authentication using the operation code is successful (step S93: YES) and the operation authentication for both the synchronization code and the operation code is successful, the intermediate unit 20 authenticates that the received control signal is a correct signal (step S94), the data in the individual test value memory, the synchronization code memory, and the operation code memory are deleted (step S95). Next, the intermediate unit 20 generates intermediate processing information from the authentication result (step S96). Next, the intermediate unit 20 includes a control signal (control signal with intermediate processing information) including the control command data 301 and accompanying data 302 included in the control signal, and the intermediate processing information 305 obtained in the process of step S96. Is generated and transmitted to the effect control unit 203 (step S97), and the processing according to this flowchart ends.

  On the other hand, in step S86, when the combined result and the expected value for individual authentication do not match (step S86: NO), the intermediate unit 20 continues until the predetermined number or more of individual authentication data 303 is received (step S98: NO). Returning to S81, the process of receiving the individual authentication data 303 and combining the individual test values is repeated. When the individual authentication data 303 of a predetermined number or more is received (step S98: YES), the intermediate unit 20 makes the individual authentication of the main control unit 10 unsuccessful (step S99), and proceeds to step S96. The intermediate unit 20 generates intermediate processing information 305 based on the authentication result of unsuccessful authentication (step S96), and transmits a control signal with intermediate processing information including the generated intermediate processing information 305 to the effect control unit 203 (step S96). S97), the process according to this flowchart is terminated.

  Further, when either the operation authentication using the synchronization code or the operation authentication using the operation code is not successful (step S91: NO or step S93: NO), the intermediate unit 20 controls the received control signal in an unauthorized manner. It detects as a signal (step S100), generates intermediate processing information 305 based on the authentication result of unsuccessful authentication (step S96), and generates a control signal with intermediate processing information including the generated intermediate processing information 305 as the effect control unit 203. (Step S97), and the process according to this flowchart is terminated.

  If each authentication data is not included in the received control signal in step S82, that is, if the received control signal is the normal control signal 300 (step S82: NO), the intermediate unit 20 performs the authentication process. The received normal control signal 300 is transmitted as it is to the effect control unit 203 (step S101), and the processing according to this flowchart ends.

  As described above, the intermediate unit 20 verifies the operation sequence of the main control unit 10 using the two types of operation inspection values of the synchronization code and the operation code. By performing authentication processing twice using two types of operation inspection values, the strength of the operation authentication processing by the intermediate unit 20 can be improved, and the operation sequence of the main control unit 10 can be verified, The continuity of operation of the control unit 10 can be authenticated, and for example, an unauthorized control board equipped with a signal switching circuit or the like can be detected.

  Further, since the individual authentication process such as the decryption of the individual authentication data and the comparison between the individual test value and the expected value for individual authentication and the operation authentication process using the operation authentication data are executed only by the intermediate unit 20, the production control unit The processing load of the CPU 203a constituting the 203 does not increase. For this reason, it is possible to prevent problems such as a reduction in the processing speed of the effect control unit 203 and a smooth display for the effect.

  In the first embodiment, after the authentication process is successful, the data in each memory is deleted in step S84. However, the present invention is not limited to this. For example, the last data stored in each memory, that is, the data in the memory is deleted while leaving the synchronization code and the operation code last generated by the main control unit 10, and generated at the end of the process related to the current authentication. The operation authentication of the main control unit 10 may be performed using the synchronization code and the operation code, and the synchronization code and the operation code generated in the process related to the next authentication. Thereby, operation | movement authentication can be performed between the process regarding this authentication, and the process regarding the next authentication.

  Next, processing related to authentication by the effect control unit 203 will be described. FIG. 16 is a flowchart illustrating an example of processing related to authentication by the effect control unit 203. First, the effect control unit 203 determines whether a control signal is received from the intermediate unit 20 (step S111). When the determination result is “NO”, the effect control unit 203 repeats the determination. And if a control signal is received from the intermediate part 20, the judgment result of step S111 will be "YES", and the production | presentation control part 203 will progress to step S112.

  In step S112, the effect control unit 203 determines whether or not the intermediate control information 305 is included in the received control signal. If the determination result in step S112 is “YES”, that is, if the received control signal includes the intermediate processing information 305, the effect control unit 203 proceeds to step S113. Here, whether or not the intermediate processing information 305 is included in the control signal is determined by, 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 accompanying data 302 or separately provided identification data (not shown) indicates that the intermediate processing information 305 is included, or in the control signal It may be determined whether the included control command data 301 is control command data of a predetermined control command set in advance for performing the authentication process.

  In step S113, the effect control unit 203 extracts the intermediate processing information 305 from the control signal, extracts the authentication result from the intermediate processing information 305, and then proceeds to step S114.

  In step S114, the effect control unit 203 determines whether or not the extracted authentication result indicates that the authentication has succeeded. If the determination result in step S114 is “YES”, that is, if the extracted authentication result indicates that the authentication is successful, the effect control unit 203 proceeds to step S115. In addition, when the determination result of step S112 is “NO”, that is, when the intermediate processing information 305 is not included in the received control signal, that is, when it is a normal control signal, the effect control unit 203 Proceed to step S115.

  In step S115, the effect control unit 203 ends the series of processes after performing the process based on the control command data 301 and the accompanying data 302. On the other hand, if the determination result in step S114 is “NO”, that is, if the extracted authentication result does not indicate that the authentication has succeeded, the effect control unit 203 proceeds to step S116. In step S116, the production control unit 203 discards the control command data 301 and the accompanying data 302, and manages the symbol display unit 104, the lamp control unit 205, or the pachinko gaming machine 1 with a notification signal for notifying an illegal act. After the transmission to the center control device or the like, the series of processing ends. In the process of step S116, 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, a specific example of the packet information selection process used to generate the synchronization code among the processes shown in FIGS. 14 and 15 will be described. FIG. 17 is a sequence diagram illustrating an example of a data flow between the main control unit 10 and the intermediate unit 20. In FIG. 17, as a selection example of the type of packet information based on the number of divisions, the type of packet information to be used is selected according to selection example 1 (here, X = 3) shown in FIG. .

  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, and the individual test value is subjected to encryption processing to generate individual authentication data (step S122).

  Next, the main control unit 10 selects packet information used for generating a synchronization code based on the number of divisions (step S123). Specifically, the number of divisions (in this case, “3”) is divided by the value of X (in this case, “3”), and packet information is selected by the remainder value. In this case, since the remainder obtained by dividing 3 by 3 is 0, the main control unit 10 selects intermittent packet information. The main control unit 10 generates an operation code while generating a synchronization code using intermittent packet information (step S124). Then, the main control unit 10 transmits an authentication data-added control signal including the individual authentication data, the synchronization code, and the operation code to the intermediate unit 20 (step S125).

  Next, processing in the intermediate unit 20 will be described. The intermediate unit 20 receives the control signal with authentication data transmitted from the main control unit 10 (step S126). Then, an individual test value is extracted from the control signal with authentication data, and a combination process is performed on the individual test value (step S127). The combined result is compared with the expected value for individual authentication, and when the combined result matches the expected value for individual authentication, the intermediate unit 20 makes the individual authentication of the main control unit 10 successful (step S128). In this case, when the combination process is performed using three individual test values, it matches the expected value for individual authentication (number of connections = 3).

  The intermediate unit 20 identifies the type of packet information used for generating the synchronization code based on the number of combinations (step S129). Specifically, in this case, since the remainder obtained by dividing 3 which is the number of connections by 3 which is X is 0, it is determined that the packet information is intermittent packet information (see FIG. 5). Subsequently, the intermediate unit 20 performs operation authentication using the synchronization code by a method corresponding to the specified packet information (step S130), and performs operation authentication using the operation code (step S131). If both the operation authentication using the synchronization code and the operation authentication using the operation code are successful, the intermediate unit 20 authenticates the control signal as a correct signal and authenticates the continuity of the operation (step S132). This is the flow of a series of selection processes.

  Turning to the description of the second process, the main control unit 10 proceeds to the process of step S133, again determines the number of divisions used for the current authentication process by an arbitrary method, and then proceeds to step S134. For example, the main control unit 10 determines that the current number of divisions is four. In step S134, 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, and the individual test value is subjected to encryption processing to generate individual authentication data (step S134).

  Next, the main control unit 10 selects packet information used for generating a synchronization code based on the number of divisions (step S135). Specifically, the number of divisions (in this case “4”) is divided by the value of X (in this case “3”). Since the remainder value is 1, the main control unit 10 selects continuous packet information. The main control unit 10 generates a synchronization code using the continuous packet information and generates an operation code (step S136). The main control unit 10 transmits a control signal with authentication data including the individual authentication data, the synchronization code, and the operation code to the intermediate unit 20 (step S137).

  Subsequently, the intermediate unit 20 receives the control signal with authentication data transmitted from the main control unit 10 (step S138), extracts the individual test value, and performs the coupling process (step S139). The combined result is collated with the expected value for individual authentication, and when the combined result matches the expected value for individual authentication, the intermediate unit 20 makes the individual authentication of the main control unit 10 succeed (step S140). In this case, when the combination process is performed using the four individual test values, it matches the expected value for individual authentication (number of connections = 4). When the combined result matches the expected value for individual authentication, the peripheral unit specifies the type of packet information used for generating the synchronization code based on the number of connections (step S141). Specifically, in this case, since the remainder obtained by dividing 4 which is the number of connections by 3 which is X is 1, it is determined that the packet information is continuous packet information.

  Then, the intermediate unit 20 performs operation authentication using the synchronization code by a method corresponding to the specified packet information (step S142) and performs operation authentication using the operation code (step S143). If both the operation authentication using the synchronization code and the operation authentication using the operation code are successful, the intermediate unit 20 authenticates the control signal as a correct signal and authenticates the continuity of the operation (step S144). The above is a series of flows.

  In this case, the main control unit 10 divides a predetermined program code stored in the ROM 10b, and changes the synchronization code generation method (the type of packet information used for generating the synchronization code) based on the number of divisions. Since the number of divisions is a value that only the main control unit 10 knows, the fraudster cannot know the type of packet information used for synchronization code generation. For this reason, it is possible to detect the cheating and the malfunction of the gaming machine.

  Note that the intermediate unit 20 may perform the individual authentication process using the individual authentication data at the time when a plurality of individual authentication data is received, instead of performing the individual authentication data every time the individual authentication data is received. In this case, for example, if the intermediate unit 20 receives the first individual authentication data together with the first control command data and the first associated data of the first control command, the intermediate unit 20 performs the control command without performing the authentication process. Processing based on the first control command data and the first accompanying data is performed. When the intermediate unit 20 receives the second individual authentication data together with the second control command data of the second control command and the second accompanying data, the intermediate control unit 20 receives the second control command data of the second control command, Before performing the process based on the second associated data, an authentication process using the first individual authentication data is performed. At this time, the intermediate unit 20 may perform the authentication process using both the first individual authentication data and the second individual authentication data.

In addition, since the intermediate unit 20 that executes the authentication process and the effect control unit 203 that mainly executes the effect process are independent of each other, the authentication program and the effect program can be designed separately. As a result, compared with the case where an authentication function is added to the production process of the production control unit 203, it is easier and less time-consuming to design, implement the function, verify the function, etc. when adding the authentication function. Can do.
Further, in the configuration in which the effect control unit 203 performs both the authentication process and the effect process as in the past, the following (a) to (c) that occur when it is necessary to change the design of any one of the above programs ) Will not occur.

(A) Since the program becomes complicated, it becomes difficult to maintain consistency with other functions (in this case, an unexpected error may occur).
(B) Although the authentication process can be made common even if the model of the pachinko gaming machine 1 is different, the production process is often different for each model of the pachinko gaming machine 1. Therefore, it is necessary to design the entire program of the processing executed by the effect control unit 203 including the authentication processing that can be shared for each model of the pachinko gaming machine 1, and the design takes a lot of time and the work efficiency is improved. bad.
(C) When changing the authentication algorithm for authentication, the process in the peripheral part 30 which performs a predetermined process must be changed. Due to this change, it takes a lot of time and labor to verify whether or not the desired authentication function can be obtained, and there is a problem that it takes a lot of time and effort to develop a gaming machine. It cannot be changed easily.

  Furthermore, in this Embodiment 1, since the intermediate | middle part 20 is provided between the main control part 10 and the production | presentation control part 203, between CPU10a which comprises the main control part 10, and CPU203a which comprises the production | generation control part 203 The intermediate unit 20 can absorb the difference in processing capacity between them and the difference in storage capacity between the ROM 10b constituting the main control unit 10 and the ROM 203b constituting the effect control unit 203. 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 constituting the main control unit 10 are the processing capacity of the CPU 203 a constituting the effect control unit 203 and the storage capacity of the ROM 203 b constituting the effect control unit 203. If there is a margin in comparison, the main control unit 10 transmits to the intermediate unit 20 the individual authentication data 303 obtained by performing complex or advanced encryption processing on each individual test value, and the intermediate unit 20 receives the data. Intermediate processing information 305 obtained by subjecting the authentication result obtained by authenticating the main control unit 10 using the individual test values obtained from the individual authentication data 303 to a relatively simple or low-level encryption process. It transmits to the production control unit 203. Then, the effect control unit 203 performs processing according to the authentication result obtained from the intermediate processing information 305. By configuring in this way, even if a complicated or advanced authentication method is not used, if an authentication process using a relatively simple authentication method is performed, between the main control unit 10 and the intermediate unit 20 and the intermediate unit A high security level can be maintained between 20 and the effect control unit 203.

  Further, the processing capacity of the CPU 203 a configuring the effect control unit 203 and the storage capacity of the ROM 203 b configuring the effect control unit 203 are the processing capacity of the CPU 10 a configuring the main control unit 10 and the storage capacity of the ROM 10 b configuring the main control unit 10. If there is room for comparison, the main control unit 10 uses the individual authentication data 303 as the individual authentication data 303 as it is, or the individual authentication data 303 obtained by performing relatively simple or low-level encryption processing on the intermediate unit 20. The intermediate unit 20 performs complex or advanced re-encryption processing on the authentication result obtained by authenticating the main control unit 10 using each individual test value obtained from the received individual authentication data 303, or After decryption processing or the like is performed on each individual test value obtained from the individual authentication data 303, more complicated or advanced re-encryption processing is performed. It sends the intermediate processing information 305 obtained by performing between operation on the performance control unit 203. Then, the effect control unit 203 performs processing according to the authentication result obtained from the intermediate processing information 305. By configuring in this way, even if a complicated or advanced authentication method is not used, if an authentication process using a relatively simple authentication method is performed, between the main control unit 10 and the intermediate unit 20 and the intermediate unit A security level can be maintained as much as possible between 20 and the effect control unit 203.

  This is not only the case where there is a difference in the processing capacity of the CPUs 10a and 203a and the storage capacities of the ROMs 10b and 203b constituting the main control unit 10 and the effect control unit 203, respectively, but there is no such difference. When all or part of one of the programs executed by the CPU 10a constituting the main control unit 10 or the CPU 203a constituting the effect control unit 203 is changed (for example, version upgrade), each individual test value or intermediate calculation result The same applies to a case where a formal difference occurs between the main control unit 10 and the effect control unit 203 in the data structure or the like.

<< Embodiment 2 >>
Hereinafter, a pachinko gaming machine according to Embodiment 2 of the present invention will be described. The pachinko gaming machine according to the second embodiment is different from the pachinko gaming machine according to the first embodiment in a method of dividing predetermined data stored in the ROM 10b in the main control unit 10 in advance. Other points are basically the same as those of the pachinko gaming machine of the first embodiment. 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.

Hereinafter, a predetermined data dividing method in the main control unit 10 will be described in detail.
The main control unit 10 determines the amount of data (hereinafter referred to as data amount) constituting each data block that is a target for generating individual test values. The data amount determination method is, for example, a method in which a value generated by a random number generation circuit (not shown) or a random number generation program constituting the program code is used as the data amount, or in other processing of the main control unit 10 A method is conceivable in which a generated value is referred to at a predetermined timing and the value is used as a data amount. For example, the main control unit 10 determines the data amount until the individual test value is generated using all of the predetermined program codes stored in the ROM 10b. The means for executing the processing for determining the data amount can correspond to, for example, the determination means 12 shown in FIG.

  Next, the main control unit 10 divides the predetermined program code in the ROM 10b by the data amount determined by the determination unit 12. Then, the main control unit 10 performs a semigroup operation for each data block, and generates individual test values for the number of divided data blocks for authenticating the main control unit 10. That is, in the second embodiment, the number of data blocks obtained by division is the number of divisions.

  For example, every time one individual test value is generated, the main control unit 10 determines the amount of data used for the generation. In this case, the main control unit 10 repeats the determination of the data amount and the generation of the individual test value until the generation of the individual test value using all the program codes in the predetermined area of the ROM 10b is completed. For this reason, in the second embodiment, how many individual test values are generated (that is, how many divisions are made) is determined by individual test values using all program codes in a predetermined area of the ROM 10b. Not sure until generation is complete.

  Instead of determining the data amount every time one individual test value is generated, the data amount used for generating the individual test value may be determined in advance. Further, the data amount used for generation of all individual test values may be made equal. In this case, the number of divisions can be predicted when the data amount is determined.

(Example of individual test value generation calculation)
An example in which the individual test value is generated by the method A using addition as the half-group operation will be described with reference to FIG. The program code storage area 400 shown in FIG. 4 stores 12 program codes (“0x01” to “0x09”, “0x0A” to “0x0C”, and the data amount of one program code is 1 byte). .
First, when the amount of data used to generate the first individual test value is determined to be 4 bytes, 4 bytes of program code (“0x01”, “0x02”) are determined from the program code stored in the program code storage area 400. , “0x03”, “0x04”) are divided into first blocks 400a. Next, the program codes “0x01”, “0x02”, “0x03”, and “0x04” stored in the first block 400a are added to obtain the first individual test value “0x0A”.

  Subsequently, when the data amount used to generate the second individual test value is determined to be 3 bytes, the program code stored in the first block 400a is excluded from the program codes stored in the program code storage area 400. A 3-byte program code (“0x05”, “0x06”, “0x07”) is divided from the program code to form a second block 400b. Next, the program codes “0x05”, “0x06”, “0x07” stored in the second block 400b are added to obtain the second individual test value “0x12”.

  Subsequently, when the data amount used to generate the third individual test value is determined to be 7 bytes, the program code stored in the program code storage area 400 is stored in the first block 400a and the second block 400b. Since the program code excluding the program code has only 5 bytes, the program code of 5 bytes (“0x08”, “0x09”, “0x0A”, “0x0B”, “0x0C”) is defined as the third block 400c. . Next, the third individual test value “0x32” is obtained by adding the program codes “0x08”, “0x09”, “0x0A”, “0x0B”, “0x0C” stored in the third block 400c. Since the main control unit 10 has generated the individual test value using all the 12 program codes stored in the program code storage area 400, the main control unit 10 ends the generation of the individual test value.

  Hereinafter, a process related to authentication in the main control unit 10 will be described. FIG. 18 is a flowchart illustrating an example of processing related to authentication by the main control unit 10. In this flowchart, a process when a data amount is determined every time an individual test value is generated and a predetermined program code is divided will be described. The main control unit 10 determines whether it is the transmission timing of the authentication data (step S152) while transmitting a normal control signal (step S151). If the determination result is NO, the main control unit 10 returns to step S151 and performs the determination in step S152 again. When the transmission timing of the authentication data comes (step S152: YES), the main control unit 10 determines the data amount of the program code used for generating the individual test value (step S153). The method for determining the data amount is arbitrary.

  Next, the main control unit 10 reads out the program data having the data amount determined in step S153 from the head of the program code storage area 400, for example, and performs a semi-group operation on the read data to generate an individual test value (Step S154), and further encryption processing is performed to generate individual authentication data (Step S155). By this processing, the method for generating the individual test value (such as the type of calculation used for generation) is determined in advance.

  Until the individual test value is generated using all data in the program code storage area 400 (step S156: NO), the main control unit 10 returns to step S153 and repeats the subsequent processing. Here, “using all the data in the program code storage area 400” means that all the data in the program code storage area 400 is used without duplication. For example, the main control unit 10 reads out data in order from the top of the program code storage area 400 and uses it to generate an individual test value. When generating the second and subsequent individual test values, the data written in the area next to the program code used to generate the previous individual test values is read by the amount determined in step S153, and the individual test values are obtained. Generate. Note that when generating the last individual test value, the data amount determined in step S153 may be insufficient, but the main control unit 10 generates the individual test value using only the program data that can be acquired. To do. In the main control unit 10, when individual test values are generated using all program codes in the program code storage area 400 (step S156: YES), the number of generated individual test values, that is, the program code is divided by the data amount. The number of data blocks obtained in this way is found, and the current number of divisions is found. The generation of the individual authentication data may be performed before the control command transmission timing.

  Next, the main control unit 10 selects the type of packet information used for generating the synchronization code based on the number of individual test values generated in step S154, that is, the number of divisions (step S157). Specifically, either intermittent packet information or continuous packet information is selected. Then, packet information corresponding to the type of the selected packet information is generated, and a synchronization code is generated based on the packet information (step S158). Note that step S157 and step S158 are interchanged to generate two synchronization codes using both intermittent packet information and continuous packet information, and select which synchronization code to use later. May be. Further, the main control unit 10 generates an operation code using the function number (step S159).

  Subsequently, the main control unit 10 adds the individual authentication data, the synchronization code, and the operation code (operation authentication data) to the control command data (step S160), and transmits a control signal with authentication data to the intermediate unit 20 (step S160). S161). The control signal with authentication data may be transmitted continuously, or may be mixed with a normal control signal and transmitted. Further, the transmission order of the authentication data is also arbitrary. The main control unit 10 returns to step S161 and repeats transmission of the control signal with authentication data until all the individual authentication data and the operation authentication data are transmitted (step S162: NO). When there is untransmitted authentication data among the generated authentication data (step S162: NO), the main control unit 10 does not newly generate authentication data, and always returns to step S161 and transmits 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 has been transmitted (step S162: YES), the processing according to this flowchart is terminated.

  Processing related to authentication in the intermediate unit 20 and the effect control unit 203 is the same as in the first embodiment. That is, the intermediate unit 20 extracts the individual authentication data from the control signal with authentication data transmitted from the main control unit 10, performs the individual authentication process using the individual authentication data, and the authentication transmitted from the main control unit 10. Operation authentication data is extracted from the control signal with data, operation authentication processing is performed using the operation authentication data, intermediate processing information is generated using each authentication result, and the control signal with intermediate processing information is transmitted to the effect control unit 203. To do. The effect control unit 203 extracts the intermediate processing information from the control signal with intermediate processing information transmitted from the intermediate unit 20, restores the authentication result from the intermediate processing information, and performs various processes according to the authentication result.

  Next, a specific example of the packet information selection process used to generate the synchronization code among the processes shown in FIGS. 15 and 18 will be described. FIG. 19 is a sequence diagram illustrating an example of a data flow between control units. In FIG. 19, as a selection example of the type of packet information based on the number of divisions, the type of packet information to be used is selected according to selection example 1 (here, X = 3) shown in FIG. . In FIG. 19, for convenience of explanation, the data amount used for generating the individual test value is collectively determined. However, as shown in the flowchart of FIG. 18, the data amount is determined every time the individual test value is generated. May be.

  First, the main control unit 10 determines the amount of data used for generating the individual test value by an arbitrary method. For example, if the total data amount is 12 bytes and the data amount used for generating the individual test value is 4 bytes, 3 bytes, and 5 bytes, respectively, three individual test values are generated, and the number of divisions = 3. (Step S171). The main control unit 10 reads 4 bytes, 3 bytes, and 5 bytes of data in order from the top of the program code storage area 400, generates three individual test values using each data, and encrypts these individual test values. To generate individual authentication data (step S172).

  Next, the main control unit 10 selects packet information used for generating a synchronization code based on the number of divisions (step S173). Specifically, the number of divisions (in this case, “3”) is divided by the value of X (in this case, “3”), and packet information is selected by the remainder value. In this case, since the remainder obtained by dividing 3 by 3 is 0, the main control unit 10 selects intermittent packet information. The main control unit 10 generates an operation code while generating a synchronization code using intermittent packet information (step S174). Then, the main control unit 10 transmits a control signal with authentication data including the individual authentication data, the synchronization code, and the operation code to the intermediate unit 20 (step S175).

  Next, processing in the intermediate unit 20 will be described. The intermediate unit 20 receives the control signal with authentication data transmitted from the main control unit 10 (step S176). Then, an individual test value is extracted from the control signal with authentication data, and a combination process is performed on the individual test value (step S177). The combined result is compared with the expected value for individual authentication, and when the combined result matches the expected value for individual authentication, the intermediate unit 20 makes the individual authentication of the main control unit 10 successful (step S178). In this case, when the joining process is performed using the three individual test values, it matches the expected value (number of bonds = 3).

  The intermediate unit 20 identifies the type of packet information used for generating the synchronization code based on the number of combinations (step S179). Specifically, in this case, since the remainder obtained by dividing 3 which is the number of connections by 3 which is X is 0, it is determined that the packet information is intermittent packet information (see FIG. 5). Subsequently, the intermediate unit 20 performs operation authentication using the synchronization code by a method corresponding to the specified packet information (step S180) and performs operation authentication using the operation code (step S181). If both the operation authentication using the synchronization code and the operation authentication using the operation code are successful, the intermediate unit 20 authenticates the control signal as a correct signal and authenticates the continuity of the operation (step S182). This is the flow of a series of selection processes.

  Turning to the description of the second processing, the main control unit 10 again determines the amount of data to be used for generating the individual test value by an arbitrary method. For example, if the data amount used for generating the individual test value is 4 bytes, 3 bytes, 2 bytes, and 3 bytes, respectively, four individual test values are generated, and the number of divisions is 4 (step S183). . The main control unit 10 reads 4 bytes, 3 bytes, 2 bytes, and 3 bytes of data in order from the top of the program code storage area 400, calculates four individual test values using each data, and these individual tests The value is subjected to encryption processing to generate individual authentication data (step S184).

  Further, the main control unit 10 selects packet information used for generating a synchronization code based on the number of divisions (step S185). Specifically, the number of divisions (in this case “4”) is divided by the value of X (in this case “3”). Since the remainder value is 1, the main control unit 10 selects continuous packet information. The main control unit 10 generates a synchronization code using the continuous packet information and generates an operation code (step S186). The main control unit 10 transmits a control signal with authentication data including the individual authentication data, the synchronization code, and the operation code to the intermediate unit 20 (step S187).

  Subsequently, the intermediate unit 20 receives the control signal with authentication data transmitted from the main control unit 10 (step S188), extracts the individual test value, and performs the combining process (step S189). The combined result is collated with the expected value for individual authentication, and when the combined result matches the expected value for individual authentication, the intermediate unit 20 makes the individual authentication of the main control unit 10 successful (step S190). In this case, when the combination process is performed using the four individual test values, it matches the expected value for individual authentication (number of connections = 4). When the combined result matches the expected value for individual authentication, the peripheral unit specifies the type of packet information used for generating the synchronization code based on the number of connections (step S191). Specifically, in this case, since the remainder obtained by dividing 4 which is the number of connections by 3 which is X is 1, it is determined that the packet information is continuous packet information.

  Then, the intermediate unit 20 performs operation authentication using the synchronization code by a method corresponding to the specified packet information (step S192), and performs operation authentication using the operation code (step S193). When both the operation authentication using the synchronization code and the operation authentication using the operation code are successful, the intermediate unit 20 authenticates the control signal as a correct signal and authenticates the continuity of the operation (step S194). The above is a series of flows.

  As described above, in the pachinko gaming machine 1 according to the second embodiment, the main control unit 10 does not determine the number of divisions itself, but determines the amount of data used for generating individual authentication data. For this reason, the possibility that the number of divisions is illegally stolen can be reduced. In the second embodiment, the effects obtained by the first embodiment are naturally obtained.

<< Embodiment 3 >>
In the said Embodiment 1, 2, although the intermediate part 20 and the production | presentation control part 203 showed the example set as a separate hardware structure, it is not limited to this.
For example, with respect to the first embodiment, one CPU has the functions of the CPU 20a configuring the intermediate unit 20 and the function of the CPU 203a configuring the effect control unit 203, and the intermediate 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, transmission and reception of data, a control signal with authentication data, and the like between the intermediate unit 20 and the effect control unit 203 function as a work area of the RAM 20c configuring the intermediate unit 20, and the effect control unit 203, for example. 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. Thus, for example, the processing of the intermediate unit 20 may be performed with a dual CPU configuration.

  Since the pachinko gaming machine 1 according to the third embodiment has the intermediate unit 20 and the effect control unit 203 configured by a single 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 intermediate unit are separated and independent on the software configuration, it is possible to develop the production control unit and the intermediate unit individually in parallel, for example, The following effects can be obtained.

[1] Since the production control unit and the intermediate 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 not possible.
[2] Since it is possible to take independent development systems for the production control unit and the intermediate unit, confidential business information (for example, an authentication processing method, etc.) when performing design and manufacturing verification of the production control unit and the intermediate unit. , Processing related to games, etc.) can be reduced out of the respective development system.

2. Ease of introduction of authentication function and ease of porting to other models Since the authentication process in the intermediate part is independent of the existing game process, transmission of authentication information between the authentication process in the intermediate part and the existing game process is It can be performed using an interface provided for existing game processing. Therefore, it becomes easy to introduce an authentication function.

  In addition, when designing, developing, and verifying a new model of a gaming machine, there is a high possibility that the difference between the function of the new model of the gaming machine and the function of the previous model is not so much related to the implementation of the intermediate part. Therefore, there is a high possibility that a slight design change is required when the middle part is shifted from the previous model to the new model.

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

4). Ease of change of authentication method When changing the authentication method or upgrading the authentication algorithm, only the main control unit and the intermediate unit need to be changed or upgraded. No need.

5). 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.

6). Reduction of processing load of the production control unit When the authentication function to be implemented in the intermediate unit is implemented by software of the production control unit, the processing load of the production control unit increases by adding an authentication function to the existing game processing of the production control unit Will do. 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 intermediate | middle part 20 between the main control part 10 and the production | generation control part 203 was shown, it is not limited to this, Between the main control part 10 and the prize ball control part 204 An intermediate portion 20 may be provided between them. 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 together with the control command data 301 and the accompanying data 302 to the main control unit 10. Then, the main control unit 10 transmits the data indicating the unsuccessfulness to the effect control unit 203 via the intermediate unit 20, and the effect control unit 203 based on the data indicating the unsuccessful, Notify that fraud has occurred.
In each of the above embodiments, the intermediate unit 20 includes a CPU, a ROM, a RAM, and the like. However, the intermediate unit 20 may be realized as an integrated circuit such as an LSI having a similar function.

  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 (the number of data blocks), and generates a synchronization code using the selected packet information. The intermediate unit 20 specifies the type of packet information used for generating the current synchronization code from a plurality of types of packet information based on the number of combinations. The intermediate unit 20 performs operation authentication using the synchronization code based on whether or not the packet information included in the synchronization code satisfies the correlation corresponding to the specified type of packet information.

  Moreover, in the pachinko gaming machine 1 according to the first to third embodiments, the individual authentication data may be generated using part or all of the synchronization code and the operation code constituting the operation authentication data. Specifically, the main control unit 10 generates operation authentication data before generating individual authentication data. Next, the main control unit 10 generates a plurality of individual test values, performs encryption processing on the generated plurality of individual test values, and generates individual authentication data. Individual authentication data is generated by performing encryption processing together with any one of them and a synchronization code or a part or all of the operation code constituting the operation authentication data. The operation authentication data used for generating the individual authentication data is determined by a predetermined determination method. In this case, the intermediate unit 20 determines the operation authentication data used for generating the individual authentication data from the received operation authentication data by the same predetermined determination method as the main control unit 10, and the determined operation authentication data and the storage unit 11. Individual authentication may be performed using a value obtained by performing a semi-group operation in combination with predetermined data stored in the data as an individual authentication test value. As described above, even when the operation authentication data is reused by an unauthorized control unit by generating individual authentication data using a part or all of the synchronization code and operation code constituting the operation authentication data. In the individual authentication process, the operation authentication data cannot be matched and fraud can be detected. Further, even if the operation authentication data is changed due to a malfunction, since the authentication is not successful, it is possible to prevent malfunction caused by the noise or the like.

  Further, in the pachinko gaming machine 1 according to the first to third embodiments, when the encryption process is performed on the synchronization code or the operation code constituting the operation authentication data, it may be performed together with a part or all of the individual authentication data. . Specifically, the main control unit 10 generates individual authentication data prior to the encryption code and operation code encryption processing. Next, when performing the encryption process of the synchronization code and the operation code, the main control unit 10 performs the encryption process by combining the synchronization code and / or the operation code with part or all of the individual authentication data. The individual authentication data used for the encryption process is determined by a predetermined determination method. In this case, the intermediate unit 20 determines the individual authentication data used for the encryption process from the received individual authentication data by the same predetermined determination method as that of the main control unit 10, and uses the determined individual authentication data for the synchronization code and The operation code may be extracted to perform operation authentication. In this way, even if the individual authentication data is reused by an unauthorized control unit by performing encryption processing on the synchronization code or operation code using part or all of the individual authentication data, the operation authentication is performed. In the process, the individual authentication data cannot be matched, and fraud can be detected. Further, even if the individual authentication data is changed due to a malfunction, since the authentication is not successful, it is possible to prevent malfunction caused by the noise or the like.

  Further, the pachinko gaming machine 1 according to the first to third embodiments has been described as adding at least one of the individual authentication data and the operation authentication data to the control command when transmitting the control command. The gaming machine is not limited to this. The main control unit 10 may output a control signal with authentication data at an arbitrary timing. For example, a control signal with authentication data may be output every predetermined time.

  In addition to the control signal with authentication data to which the individual authentication data and the operation authentication data are added, the main control unit 10 has a control signal with individual authentication data in which only the individual authentication data is added to the control command data and accompanying data, A control signal with operation authentication data in which only operation authentication data is added to the control command data and accompanying data may be transmitted to each intermediate unit. Alternatively, the synchronization code and the operation code constituting the operation authentication data may be added to different control signals and transmitted separately to the intermediate unit. However, when the individual authentication data and the operation authentication data are transmitted separately (when the control signal with individual authentication data and the control signal with operation authentication data are transmitted respectively) and the individual authentication data is generated using the operation authentication data. If it is, the operation authentication data needs to be transmitted before the individual authentication is performed. Similarly, when the operation authentication data is encrypted using the individual authentication data, it is necessary to transmit the individual authentication data before the operation authentication is performed.

  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 to the intermediate unit 20 a control signal with authentication data in which the generated individual authentication data and operation authentication data are added to the control command. 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.

  Further, in the pachinko gaming machine 1 according to the first to third embodiments, at least one of individual authentication data, a synchronization code, and an operation code is used as a control command only when a predetermined control command is transmitted, for example, a predetermined control command. You may make it add and transmit. In this case, the main control unit 10 determines whether or not the control command is a predetermined control command, and adds at least one of the individual authentication data, the synchronization code, and the operation code to the control command only when the control command is the predetermined control command. A control signal with authentication data is transmitted to the intermediate unit 20, and a normal control signal is transmitted to the intermediate unit 20 for a control command other than a predetermined control command. The intermediate unit 20 determines whether the control command is a predetermined control command, or determines whether at least one of individual authentication data, a synchronization code, and an operation code is added to the control command. . When a normal control signal is transmitted, the intermediate unit 20 transmits the normal control signal as it is to the effect control unit 203, and the effect control unit 201 performs processing based on the received normal control signal.

  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 part to execute the process of reaching the jackpot, a power-on command for causing the peripheral part to execute a power-on process, and a demonstration display in the non-game state on the peripheral part A customer waiting demo command to be executed, a customer waiting demo stop command to stop the demonstration display in the non-gaming state in the peripheral part, and a quit command to cause the peripheral part to execute processing when the lottery result at the lottery is off , Like the open lottery of ordinary electric accessories (electric tulips) and the jackpot called the so-called fake It refers to such small hit command transmitted for the duration of the small contact state such as another electric combination thereof is opened for a short time. 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 effect control unit 203 increases by performing the authentication process only during a period in which the control command data 301 of a predetermined control command is received. The rate at which the processing load of the unit 203 increases can be suppressed.

  Further, since the authentication data 303 is added only to the control command data 301 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 effect control unit 203. Accordingly, since it is not necessary to design a new timing for the entire program executed by the effect control unit 203, an authentication function is added as compared with the case where the authentication data 303 is added to the control command data 301 of all control commands. Designing timing, implementing functions, verifying functions, etc. can be achieved more easily and with less work man-hours.

  Further, only when the main control unit 10 transmits a predetermined control command to the intermediate unit 20, when at least one of the individual authentication data 303 or the operation authentication data is added to the control command data 301, an authentication process is performed. Is only at the time of transmission of control command data of a predetermined control command, it is possible to suppress the rate at which the processing load of the main control unit 10 and the effect control unit 203 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 303 is extracted from the control signal can be reduced. Further, even if the authentication data 303 is extracted from the control signal, the number of samples that can be acquired is small, so that the risk of the authentication data 303 being 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 effect control unit 203 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. it can. 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.

  The intermediate unit 20 may add the intermediate processing information 305 to the control command only when transmitting a predetermined control command to the effect control unit 203. In this case, since the authentication process of the intermediate unit 20 is performed only when a predetermined control command is transmitted, the rate at which the processing load of the effect control unit 203 increases due to the authentication process can be suppressed.

  In addition, 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 expected value for individual authentication. It is not limited to this. 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 intermediate unit 20 may be configured to switch the individual authentication expected value based on the number of connections corresponding to the switching of the individual test value generation method in the main control unit 10. Specifically, for example, when the current division number is an odd number, the main control unit 10 selects the next half group calculation different from the currently used half group calculation, and when the current division number is an even number, The next half group calculation is the same as the half group calculation used this time. Further, the intermediate unit 20 switches the individual test value generation method and the individual authentication expected value when the number of divisions and the number of connections are odd, and generates the individual test value used previously when the number of divisions and the number of connections is even. Continue to use the method and expected values for individual authentication. 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 intermediate unit 20. The number of divisions is a value that only the main control unit 10 knows, and the intermediate unit 20 can know the value as the number of connections only when individual authentication is successful. Therefore, the fraudster cannot know the number of divisions and the number of connections, and cannot know the switching timing of the individual test value generation method. Thereby, it is possible to prevent an individual inspection value from being illegally generated by an unauthorized person.

In addition, the pachinko gaming machine 1 according to the first to third embodiments generates an operation code using a predetermined generation method, and performs an operation authentication process using the operation code using a predetermined operation code expected value. It is not limited to this. The main control unit 10 prepares a plurality of operation code generation methods in advance, and generates one operation code used to generate the next operation code from the plurality of operation code generation methods based on the current number of divisions. The intermediate unit 20 is configured to switch the operation code generation method and the expected value for the operation code based on the number of connections in response to the switching of the operation code generation method in the main control unit 10. May be. Specifically, for example, when the current division number is an odd number, the main control unit 10 selects a next operation code generation method that is different from the operation code generation method used this time, and the current division number is an even number. In this case, the next operation code generation method is the same as the operation code generation method used this time. The intermediate unit 20 switches the operation code generation method and the expected value for the operation code when the number of connections is odd, and the operation code generation method and the expected value for operation code used last time when the number of connections is an even number. Continue to use. In this case, the first operation code generation method is set in advance to use the same method between the main control unit 10 and the intermediate unit 20. The number of divisions is a value that only the main control unit 10 knows, and the intermediate unit 20 can know the value as the number of connections only when individual authentication is successful. Therefore, the fraudster cannot know the number of divisions and the number of combinations, and cannot know the switching timing of the operation code generation method. Thereby, it is possible to prevent an individual inspection value from being illegally generated by an unauthorized person.

  In the pachinko gaming machine 1 according to the first to third embodiments, when a function number is used as an operation code, the function number is executed for each process for executing a predetermined function of a program executed by the main control unit 10. You may assign | assign the number which increases or decreases continuously according to the order performed without duplication. By assigning the function number in this way, the intermediate unit 20 restores the operation code from the received operation authentication data, and performs operation authentication by determining whether or not the values of the operation code are consecutive in the order received. be able to. That is, it is not necessary for the intermediate unit 20 to store the operation code expected value in advance or perform the collation process using the operation code and the operation code expected value in order to perform the operation authentication. Thereby, it is possible to reduce the processing load due to the operation authentication of the intermediate unit 20 and the data amount related to the operation authentication by the operation code occupying the storage area of the intermediate unit 20.

In the pachinko gaming machine 1 according to the first to third embodiments, the function number and the number of authentications are exemplified as the operation code, but the number of transmissions of the control command may be used as the operation code. In this case, the intermediate unit 20 may perform the operation authentication process using the number of received control commands, that is, the number of receptions of the control command as an expected value for operation authentication. When the control command transmission timing comes, the main control unit 10 updates the value of the control command transmission count stored in the operation code memory of the RAM 10c by +1, and acquires the updated transmission count as the operation code. . The main control unit 10 performs operation and encryption processing on the acquired operation code to generate operation authentication data, adds the generated operation authentication data to the control command, and transmits it to the intermediate unit 20. When the intermediate unit 20 receives the control command to which the operation authentication data is added, the intermediate unit 20 extracts the operation authentication data, updates the operation code expected value stored in the RAM 20c by +1, and extracts the extracted operation authentication data. And perform the operation authentication using the updated expected value for the operation code.

  Further, the number of individual test values generated by the main control unit 10 (that is, the total number of divisions) may be used as the operation code. In this case, the intermediate unit 20 may perform authentication processing using the number of pieces of individual authentication data transmitted from the main control unit 10 (that is, the total number of connections) as the expected value for operation code. When the operation code update timing comes, the main control unit 10 adds the number of individual test values newly generated this time to the number of individual test values stored in the RAM 10c as the operation code (the number of individual test values ( Update the operation code). When it is time to update the expected value for operation code, the intermediate unit 20 adds the number of individual test values subjected to the current individual authentication process to the value of the expected value for operation code stored in the RAM 20c (that is, this time The expected value for the operation code is updated.
