(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. An encryption unit; a transmission unit that transmits data obtained by encrypting control data corresponding to a game situation to the peripheral unit; and a first key change unit that changes the first key data at a predetermined timing. ing. The peripheral unit performs the processing corresponding to the second key data on the second storage means for storing the second key data and the encrypted data received from the main control unit, thereby verifying the validity of the received encrypted data. An authentication means for determining and authenticating the encrypted data if it is valid, an operation control means for causing the symbol display device to perform an operation corresponding to the encrypted data when the received encrypted data is authenticated, and a first key Second key change means for changing the second key data so as to correspond to the first key data at a predetermined timing so as to coincide with the data change timing (see, for example, Patent Document 2). ). Hereinafter, this technique is referred to as a second conventional example.

  In addition, some conventional pachinko gaming machines include a main control board (main control unit) and a peripheral board (peripheral part) that performs predetermined processing based on a control command transmitted by the main 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.

Corresponds to the above binary calculation among the calculated values An individual authentication unit that performs individual authentication of the main control unit based on whether or not the calculated value matches, and when the individual authentication of the main control unit is successful by the individual authentication unit, from the main control unit Operation authentication means for performing operation authentication of the main control unit based on whether information indicating continuity of operation of the main control unit included in a code added to the transmitted control command satisfies a predetermined condition The authentication result obtained by the individual authentication unit and the authentication result obtained by the operation authentication unit are added to the control command transmitted from the main control unit and transmitted to the peripheral unit. .

  Furthermore, in order to solve the above problems, the peripheral board of the gaming machine of the present invention is characterized in that the intermediate part and the peripheral part of the present invention are mounted.

Furthermore, the present invention in order to solve the above problems, a main control unit for outputting a control command, and an intermediate portion connected to the main control unit, a process corresponding to the connected to the intermediate portion and the control command An authentication method used in a gaming machine including a peripheral unit to perform, when the main control unit outputs a control command, divides predetermined data stored in data storage means of the main control unit, It includes information indicating the continuity of the operation of the main control unit by generating one inspection value by performing one binary operation of one or a plurality of binary operations satisfying the combining law on the divided data. A first step of generating a code, adding the test value and the code to the control command and transmitting the code to the intermediate unit; and the intermediate unit adds the test value to the test value added to the control command. When the is generated One or more obtained by performing a term operation, and performing the same binary operation as the one or plural binary operations on the same data as the calculation result and the predetermined data stored in the data storage means When the individual authentication of the main control unit is performed based on whether or not a calculation value corresponding to the two-term calculation among a plurality of calculation values matches, and when the individual authentication of the main control unit is successful, the control Based on whether the information indicating the continuity of the operation of the main control unit included in the code added to the command satisfies a predetermined condition, the operation authentication of the main control unit is performed, the authentication result of the individual authentication, and A second step of adding an authentication result of the operation authentication to the control command transmitted from the main control unit and transmitting the result to the peripheral unit.

Furthermore, computer-readable authentication program of the present invention in order to solve the above problems, a main control unit for outputting a control command, and an intermediate portion connected to the main control unit, connected to the intermediate portion and the When the main control unit outputs a control command to a computer mounted on a gaming machine that includes a peripheral unit that performs processing according to the control command, a predetermined storage stored in the data storage unit of the main control unit Continuation of the operation of the main control unit by dividing the data, performing one binary operation of one or more binary operations that satisfy the combining law on the divided data, and generating a test value generates code that contains information indicating a first function of transmitting to the intermediate portion by adding the check value and the code to the control command, wherein the intermediate portion is added to the control command the The binary operation when the inspection value is generated as the inspection value is performed, and the calculation result and the same data as the predetermined data stored in the data storage means are added to the one or more binary operations. And performing individual authentication of the main control unit based on whether or not the calculation value corresponding to the two-term calculation out of one or a plurality of calculation values obtained by performing the same two-term calculation, When the individual authentication of the main control unit is successful, the main control unit includes information indicating the continuity of operation of the main control unit included in the code added to the control command based on whether or not a predetermined condition is satisfied. Performing the operation authentication of the control unit , and realizing the second function of adding the authentication result of the individual authentication and the authentication result of the operation authentication to the control command transmitted from the main control unit and transmitting to the peripheral unit Features.

  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.

  In this way, by authenticating both the legitimacy of the individual of the main control unit and the continuity of the operation, it is possible to ensure the detection of the fraudulent act and the malfunction of the gaming machine, and unreasonably many players The game medium is paid out, and it is possible to prevent the game store from being damaged greatly. Also, by switching and authenticating multiple types of codes for authenticating continuity of operation, it is possible to improve the strength of authentication compared to the case of authenticating continuity of operation with one code It becomes.

  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 in order to generate a test value, and performs processing related to operation authentication based on the number of divided data (number of divisions). Select the type of code to generate to generate the synchronization code. 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. Identify the type of code that is recognized as generated. Since the number of divisions is a value that only the main control unit can know, and the number of connections is the value that the intermediate part can know only after successful individual authentication, the fraudster is responsible for the type of code used to generate the synchronization code. 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 main control unit from the viewpoint of the validity of the individual and the continuity of the operation order by using two types of authentication data of the individual authentication data and the operation authentication data. By performing authentication processing twice using two types of authentication data in this way, the strength of authentication processing by the intermediate unit can be improved, and the main control unit can be verified by verifying the operation sequence of the main control unit. The continuity of the operation of the unit can be authenticated, and for example, an unauthorized control board equipped with a signal switching circuit or the like can be detected.

  Further, an accessory operating device 231 is connected to the output side of the main control unit 10. In the first embodiment, the accessory actuating device 231 opens and closes the first big prize opening opening / closing solenoid 109b and the second big prize opening opening / closing door 109a and the second big prize opening opening / closing door 129a, respectively. A solenoid 129b and a second start port opening / closing solenoid 120b for opening and closing the second start port 120 are configured.

  The accessory actuating device 231 is controlled by the main control unit 10 and energizes the first big prize opening / closing solenoid 109b to open the first big prize opening opening / closing door 109a or play a short hit game and small game during long play.

  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 described in [1] to [7] below, but the encryption processing in [3] and [5] 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 acquires 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 Inspection Value Next, the main control unit 10 divides the storage area in the ROM 10b in which a predetermined program code is stored in advance by the number of divisions determined in the process [1]. Then, the main control unit 10 performs a binary operation on the program code stored in each divided storage area of the ROM 10b, and generates test values for the number of divisions for authenticating the main control unit 10. To do. Note that the test value generation method (for example, the type of binary operation that satisfies the combining rule used for the test value generation) is determined at the time of the previous transmission of the control signal with authentication data.

“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 ♪ whose 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 of generating each inspection value will be described with reference to FIG.
FIG. 4 is an explanatory diagram schematically showing a method for generating inspection values in the main control unit 10. The inspection 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 ( A 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 inspection value generation calculation≫
An example of the calculation for inspection 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 a 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 inspection value “0x0A” is obtained by addition. Similarly, three program codes “0x05”, “0x06”, “0x07” stored in the second block 400b are added, and the second inspection value “0x12” is stored in the third block 400c. Program codes “0x08”, “0x09”, “0x0A”, “0x0B”, and “0x0C” are added to obtain a third inspection value “0x32”, respectively.

  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 inspection value“ 0x04 ”. Similarly, exclusive OR operation is performed on the three program codes “0x05”, “0x06”, “0x07” stored in the second block 400b, and the second check value “0x04” is stored in the third block 400c. A third check value “0x0C” is obtained by performing an exclusive OR operation on the five program codes “0x08”, “0x09”, “0x0A”, “0x0B”, and “0x0C”.

  In the first embodiment, as will be described later, when the output control command is a predetermined control command, the main control unit 10 uses the data indicating the predetermined control command as data for authenticating the main control unit 10. It is added to (control command data) and transmitted to the intermediate unit 20. Here, the data for authenticating the main control unit 10 added to the control command data will be collectively referred to as “authentication data”. That is, the authentication data includes each inspection value, data obtained by performing encryption processing on these inspection values (individual authentication data), and each code of the operation code, relative time code, and synchronization code, or these This is data (operation authentication data) obtained by performing encryption processing on each code. Hereinafter, in the present embodiment, the authentication data is described as data obtained by performing an encryption process on the inspection value, and data obtained by performing an encryption process on each code or each of these codes. However, the present invention is not limited to this, and processing relating to authentication may be performed using the inspection value and each code itself as authentication data. In this case, it is not necessary to perform an encryption process on the inspection value in the main control unit 10, and it is not necessary to perform a decryption process on each authentication data when extracting the inspection value and each code in the intermediate unit 20. Processing can be simplified and increase in processing load can be suppressed.

  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.

  The means for executing the process for generating the inspection value can correspond to, for example, the inspection value generation means 13 shown in FIG.

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

  In the main control unit 10, when each individual authentication data obtained by performing encryption processing on each test value is transmitted to the intermediate unit 20, each test value that has not been subjected to any processing is directly stored in the intermediate unit. Compared with the case of transmitting to 20, it is possible to reduce the possibility that each inspection value is analyzed by a fraudster. Note that the main control unit 10 may perform different encryption processing on each inspection 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 each inspection value subjected to encryption processing, these four arithmetic operations or logical operations A process for rearranging the bit arrangement of the operation data obtained by the above, a process for shifting or rotating the bits of the operation data, and a plurality of bits constituting each inspection value subjected to the encryption process For example, a process of generating one piece of data in accordance with the above 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 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 inspection value “0x0A” shown in FIG. 4 will be described. As the encryption process, a process of adding control command data to the inspection 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 inspection 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 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 inspection value “0x12” recorded in the program code storage area 400 shown in FIG. 4, individual authentication data is generated from the value “0xF2” and the third inspection value “0x32”. Then, the value becomes “0x1D”.

  Note that the individual authentication data may be generated by performing an encryption process on the data including the inspection 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.

  Further, when including data related to control command data and accompanying data in the individual authentication data, the main control unit 10 performs encryption processing by combining the data related to the control command data and the accompanying data and the inspection value, thereby obtaining the individual authentication data. You may perform the process to produce | generate.

  The timing at which the main control unit 10 generates each test value and the timing at which individual authentication data is generated using each test value are not particularly limited, and each test value is included in the control program of the main control unit. A program for performing the process of generating the authentication data and the process of generating the individual authentication data using each inspection value may be incorporated.

[4] Code Determination The main control unit 10 generates operation authentication data among three types of codes (operation code, relative time code, and synchronization code) including information indicating continuity of operation of the main control unit 10. Determine the code used for.
Therefore, the operation code, the relative time code, and the synchronization code that are generated as the operation authentication data, which is information for confirming that the main control unit 10 continuously transmits the control command by the main control unit 10. explain.

≪Operation code≫
The operation code is, for example, a code composed of a program function process number (function number), an individual authentication data test value generation process execution number (authentication number), a value that varies according to a predetermined rule, and the like. The intermediate unit 20 can determine whether or not the operation (in this case, transmission of control commands) sequence of the main control unit 10 is continuously performed by referring to the operation code. Below, the code comprised by a function number and the frequency | count of authentication is demonstrated as an example of an operation code.

  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 in a predetermined area of the RAM 10c in a state in which the acquired order can be determined. For example, the main control unit 10 stores a plurality of acquired function numbers in the order of acquisition. The plurality of operation codes arranged and stored in the order obtained in this way indicate the operation sequence when the main control unit 10 executes various programs, and the continuity of the operation of the main control unit 10 It is information indicating.

  Here, a specific example of how to assign the 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. Also, function number 2 is assigned to the jackpot start command. Then, function numbers 3 to 18 are assigned to the respective commands of the 15-round jackpot command. In this way, the continuity of the operation sequence of the main control unit 10 is determined by assigning consecutive function numbers to the control commands that are continuously generated in time series and checking the continuity of the function numbers that are continuously generated. Can be authenticated. 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 authentications is the number of times that the main control unit 10 has performed the individual authentication value generation process. The main control unit 10 stores the number of authentications as an operation code in a predetermined 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. The operation code using the number of authentications generated in this way is information indicating the continuity of the operation of the main control unit 10.

  The operation code includes information such as a function number set in accordance with the operation procedure of the control command execution program for performing the operation in addition to the information regarding the operation sequence of the control command transmission by the main control unit 10. May be included. At this time, a plurality of pieces of information regarding the operation order may be included as they are, or a value obtained by performing a predetermined calculation on these pieces of information may be included.

  As described above, by using an operation code (for example, a function number, the number of times of authentication, etc.) for authenticating what operation the main control unit 10 is performing when a predetermined control command is output, If the authenticated operation sequence is not continuous, it is determined that the control command is transmitted from an unauthorized control board other than the control command transmitted from the main control unit 10, and unauthorized control can be detected.

≪Relative time code≫
The relative time code is, for example, a code that sets a certain reference value from the time measurement information and is represented by a difference value or a cumulative value from the reference value. The main control unit 10 generates a plurality of relative time codes including timing information acquired at a timing specified in advance. Note that the timing information acquisition timing in the code generation unit 14 of the main control unit 10 is not fixed on the time axis. For example, if the timing information is set to be triggered by the timing at which an event to be awarded is triggered, it is not known when the prize ball event will occur, so the timing for obtaining time information cannot be specified on the time axis. .

  In addition, the clocking function of the code generation means 14 of the main control unit 10 may be as simple as starting timing with a game operation start time as a trigger, such as when the power is turned on or reset. In the case of the code generation means 14, for example, it is not necessary to provide an initialization processing function for the purpose of fixing or setting an initial value such as reset processing or clear processing at the start of timing. In addition, after the start of timing, the timing information may be output using a specific event that occurs at random, such as when an event to be awarded occurs. Therefore, it can be realized with a very simple configuration and has a feature that the processing load is light.

<< Synchronization code >>
The main control unit 10 continuously outputs packet information (continuous packet information) with transmission of control commands and packet information (intermittent packet information) output at predetermined intervals with transmission of control commands. A synchronization code is generated using any of the above.

  The continuous packet information is packet information output by at least two (two times) continuous timings generated by the main control unit 10. The output timing described here is an output timing corresponding to the processing speed of the main control unit 10. That is, if packet information can be output at every clock timing, every clock timing becomes an output timing, and if packet information can be outputted every 4 clock timings, every 4 clock timing becomes an output timing.

  When a synchronization code is generated using continuous packet information, each packet information has a correlation of a predetermined interval. Therefore, the operation authentication unit 23 can authenticate the continuity of the operation of the main control unit 10 by obtaining a correlation between a plurality of packet information.

  The intermittent packet information is packet information output at least two (two times) output timings (output timings at predetermined intervals) among the packet information generated by the main control unit 10. is there. The preset timings at arbitrary intervals described here mean, for example, intermittently continuous timings. For example, a clock timing such as every 1 clock timing or every 4 clock timings may be used as a reference, or a time such as every 1 second or every 0.5 seconds may be used as a reference.

  When generating a synchronization code using intermittent packet information, each packet information is transmitted at an arbitrary interval, for example, a predetermined time interval, a predetermined clock number interval, or the like, along with transmission of a control command of the main control unit 10. It is output at the output timing set at the interval of instruction execution. For this reason, when packet information of continuous output timing is compared, the continuity of operation of the main control unit 10 is authenticated by obtaining a correlation between the packet information. As the synchronization code, values acquired as packet information may be used as they are, or values obtained by performing a predetermined operation on these values may be used.

  Next, a code determination method (selection method) used for generating operation authentication data from the above-described three types of codes will be described. FIG. 5 is an explanatory diagram schematically showing a code determination method in the main control unit 10. As a method for selecting a code based on the number of divisions, for example, a method as shown in FIG.

<< Selection example 1: Number of divisions / Remainder value of X >>
In selection example 1, a code is selected based on a remainder value obtained by dividing a value determined as the number of divisions by a specific value X. For example, if the specific value X = 4 and the number of divisions = 7, the remainder value = 3, and in the selection example 1 in FIG. 5, the synchronization code is selected (determined) as the code for operation authentication.

≪Selection example 2: previous division number−absolute value of current division number≫
In selection example 2, a code is selected based on a remainder value obtained by subtracting the currently determined number of divisions from the previously determined number of divisions. For example, if the previous division number = 3 and the current division number = 4, the absolute value | −1 | = 1, and in the selection example 2 in FIG. 5, the relative time code is selected (determined) as the code for operation authentication. )

  Note that the selection method described above is merely an example, and the method for selecting a code used to generate the operation authentication data is not limited to this.

[5] Generation of operation authentication data The main control unit 10 performs an encryption process on the code selected in the process [4], and generates operation authentication data to be added to predetermined control command data and accompanying data. . Here, as the encryption method, the same method as that used when generating the individual authentication data of [3] above can be considered. The main control unit 10 may perform different encryption processing on each code.

  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 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] Addition of authentication data 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. A control signal with authentication data is generated.

[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. As shown in FIG. 6 (1), the normal control signal 300 output from the main control unit 10 includes 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.

  In the first embodiment, for simplification of description, when the main control unit 10 transmits authentication data to the intermediate unit 20, as shown in FIG. Description will be made assuming that the control signal with authentication data 310 including the individual authentication data 303 and the operation authentication data 304 in addition to 302 is generated and output. When transmitting the authentication data to the intermediate unit 20, the main control unit 10 adds individual authentication data including the individual authentication data 303 in addition to the control command data 301 and the accompanying data 302 as shown in FIG. Generate and output the control signal 311 or generate and output the operation authentication data-added signal 312 including the operation authentication data 304 in addition to the control command data 301 and the accompanying data 302 as shown in FIG. You may make it do.

  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 control signal 311 with individual authentication data, the control signal 312 with operation authentication data, the normal control signal 320 shown in FIG. 7 described later, and the control signals 321, 322, and 323 with intermediate processing information.

  Note that the control signal with authentication data is not limited to the order shown in FIG. 6. For example, the individual authentication data 303 or the operation authentication data 304 is set to the head of the control signal, or the individual authentication is performed between the control command data 301 and the accompanying data 302. Data 303 or operation authentication data 304 may be inserted.

  Further, the authentication data may be output separately from the control command data 301 and the accompanying data 302. For example, after transmitting a control signal including jackpot command data, authentication data may be added at the time of the third control signal transmission.

  Further, in the control signal with authentication data, the individual authentication data 303 and the operation authentication data 304 are not necessarily adjacent to each other, and the control command data 301 and the accompanying data 302 may be arranged between the respective authentication data.

  As described above, by including the authentication data in the control signal, an increase in communication load between the main control unit 10 and the effect control unit 203 can be suppressed as compared with the case where the authentication data is transmitted alone. Further, by including the authentication data in the control signal, it is possible to reduce the risk that the authentication data is extracted from the communication data and analyzed as compared with the case where the authentication data is transmitted alone.

(Middle 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 obtained in this manner are stored in advance. Among the storage areas of the ROM 20b, the storage area in which the plurality of expected values 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.

  The intermediate unit 20 according to the first embodiment performs processing related to authentication of the main control unit 10 for preventing fraud with the above-described configuration. Processing related to this authentication is as shown in [1] to [7] below.

[1] Reception of Control Signal The intermediate unit 20 receives a normal control signal 300 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, and the individual authentication data 303. And the control signal with authentication data 310 including the operation authentication data 304 is received. As described above, the control signal 311 including the control command data 301, the accompanying data 302 and the individual authentication data 303, and the operation authentication data including the control command data 301, the accompanying data 302 and the operation authentication data 304 are attached. A control signal 312 may be received. The intermediate unit 20 transmits the normal control signal 300 to the effect control unit 203 as it is.

[2] Extraction of Test Value and Code The intermediate unit 20 extracts the individual authentication data 303 and the operation authentication data 304 from the control signal 310 with authentication data. Next, the intermediate unit 20 applies a decryption process corresponding to the encryption process used at the time of generating each authentication data to the extracted individual authentication data 303 and the operation authentication data 304, and extracts a test value and a code. Then, the intermediate unit 20 stores the extracted inspection value and code in a predetermined storage area (inspection value memory and code memory) of the RAM 20c.

[3] Individual authentication The intermediate unit 20 performs the semi-group operation on all the test values stored in the test value memory in the following order, so that the main control unit 10 performs normal main control. Individual authentication is performed as to whether or not a part is a part.
The {1} intermediate unit 20 performs a half-group operation (hereinafter referred to as a combining process) using all the inspection values stored in the inspection value memory.
{2} The intermediate unit 20 reads an expected value corresponding to a half-group operation determined according to a predetermined rule from a plurality of expected values stored in advance in the operation value storage unit 21 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 join result) matches the expected value read out in the process {2} (hereinafter referred to as a matching process). Called).
The intermediate unit 20 determines that the individual authentication is successful when the combined result and the expected value match.
Since the semi-group operation satisfies the above combination rule, an expected value that is a result obtained by performing the semi-group operation on all of the predetermined program codes stored in advance in the ROM 10b of the main control unit 10, This coincides with the combined result obtained by performing the semi-group operation on the inspection values for the number of divisions generated from the predetermined program code. 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 do not match, the intermediate unit 20 determines that the individual authentication has not succeeded.

When the individual authentication is successful in the processing of {4} {3}, the intermediate unit 20 generates an authentication result indicating that the individual authentication is successful.
{5} The intermediate unit 20 erases all inspection values stored in the inspection value memory.

If the individual authentication is not successful in the process of {6} {3}, the intermediate unit 20 determines whether or not the number of individual authentication data received from the main control unit 10 is equal to or greater than a predetermined number. The predetermined number is an arbitrary number within a range that is equal to or larger than the current number of divisions and less than or equal to the number of divisions (maximum number of divisions) of the program code stored in the program code storage area 400 (see FIG. 4). .
{6-1} If 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 at a stage where the individual authentication can be performed. An arbitrary value (for example, all 0 or all 1) having the same data length as the data length of the result is generated.
{6-2} If the number of received individual authentication data is a predetermined number or more, the intermediate unit 20 determines that the individual authentication has not been successful, and generates an authentication result indicating that the individual authentication has not been successful. .

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

  The expected value used by the intermediate unit 20 for collation may be stored in advance in a predetermined storage area of the ROM 20b that constitutes the intermediate unit 20 at the time of manufacture, for example. It is good also as transmitting to 20. Examples of other components include a prize ball control unit 204 and a dedicated processing unit (hereinafter referred to as an expected value calculation unit) for generating an expected value. Note that the expected value calculation unit may transmit the expected value stored in advance to the intermediate unit 20. In addition, a coefficient necessary for calculating an expected value may be transmitted from an external device to the intermediate unit 20 or the expected value calculating unit via an external connection interface (not shown). As described above, if the expected value is not stored in advance in the predetermined storage area of the ROM 20b that constitutes the intermediate unit 20 and is obtained from another component, the inspection value can be changed afterwards. It becomes.

[4] Operation Authentication The intermediate unit 20 performs operation authentication on the extracted code as to whether or not the main control unit 10 is a regular main control unit. In the first embodiment, the intermediate unit 20 determines that the code used as the operation authentication data is the operation code and the relative time based on the number of inspection values (the number of combinations) that are the targets of the combination process when the authentication is successful. It is assumed that either the code or the synchronization code is specified, and the main controller 10 is authenticated for operation using the specified code.

≪Operation code authentication≫
As described above, the operation code in the first embodiment is, for example, a program function process number (function number), an individual authentication data test value generation process execution number (authentication number), a value that varies according to a predetermined rule, and the like. Is a code constructed by

  For example, when the operation code is generated using a function number, the intermediate unit 20 performs a collation process for determining whether a plurality of function numbers are arranged in a normal order. As a result of the collation processing, when a plurality of function numbers are arranged in a regular order, the intermediate unit 20 determines that the operation authentication is successful. On the other hand, if the plurality of function numbers are not arranged in the regular order, the intermediate unit 20 determines that the operation authentication has not been successful.

  When the operation code is generated using the number of authentications, the intermediate unit 20 matches, for example, the expected value for operation authentication that is a value obtained by performing the same encryption process as the encryption process performed on the number of authentications. A collation process is performed to determine whether or not to do so. As a result of the collation processing, when the operation authentication data matches the expected value for operation authentication, the intermediate unit 20 determines that the operation authentication is successful. On the other hand, when the operation authentication data and the expected value for operation authentication do not match, the intermediate unit 20 determines that the operation authentication has not been successful.

  When the operation authentication is successful, the intermediate unit 20 generates an authentication result indicating that the operation authentication is successful, and erases all operation codes stored in the code memory. On the other hand, when the operation authentication is not successful, the intermediate unit 20 generates an authentication result indicating that the operation authentication is not successful.

≪Authentication of relative time code≫
In the first embodiment, the intermediate unit 20 authenticates the continuity of the operation of the main control unit 10 based on whether the timing information included in the relative time code stored in the code memory has continuity. . First, the main control unit 10 sets a certain reference value from the time measurement information, generates a plurality of relative time codes as difference values or accumulated values from the reference value, and transmits them to the intermediate unit 20. Then, the intermediate unit 20 authenticates the continuity of the operation of the main control unit 10 based on whether or not the value of the received relative time code has increased in time series. As a result, the intermediate unit 20 determines that the timing information has continuity when the value of the relative time code increases in time series, and the operation of the main control unit 10 has continuity. Authenticate that it is in the correct order. In addition, the intermediate unit 20 can determine that there is a possibility that an unauthorized control command has been transmitted when it is not determined that the operation sequence authenticated by the relative time code is a continuous operation.

  As described above, the intermediate unit 20 can easily determine whether or not the operation being executed in the main control unit 10 is continuously performed by referring to the relative time code. Therefore, it is possible to take measures against illegal acts and malfunctions of the gaming machine.

  When a predetermined calculation is performed on the relative time code in the main control unit 10, the intermediate unit 20 generates a relative time code by performing a predetermined calculation according to the content of the calculation process of the main control unit 10. . When the relative time code is a code indicating that the operation of the main control unit 10 continues, the operation of the main control unit 10 is authenticated as an operation in the correct order. In addition, when the intermediate unit 20 directly receives the relative time code, the intermediate unit 20 authenticates the operation order of the main control unit 10 using the relative time code.

  Note that after the authentication is successful, the intermediate unit 20 deletes the relative time code stored in the code memory.

≪Authentication of synchronization code≫
In the first embodiment, in the synchronization code authentication process, the synchronization state is verified from the correlation between two pieces of packet information output by the main control unit 10 at successive timings. For example, when the basic value of the first packet (hereinafter referred to as “packet 1”) = 0x03, and the basic value of the second packet (hereinafter referred to as “packet 2”) = 0x05, the correlation condition between packet 1 and packet 2 (Authentication establishment condition) is “+2”. Then, the inspection value of packet 1 transmitted from the main control unit 10 is 0x03 as the basic value, the inspection value of packet 2 is the sum of packet 1 and packet 2, that is, 0x03 + 0x05, and “0x08” is transmitted to the intermediate unit 20 The

  Next, the packet 1 received by the intermediate unit 20 is 0x03 as the basic value, and the inspection value of the packet 2 is 0x08. Then, the intermediate unit 20 subtracts the packet 1 from the received packet 2 in order to calculate the basic value of the packet 2, and obtains 0x08-0x03 = 0x05.

  When the basic values of both packet 1 and packet 2 are obtained, the correlation between the two packets is the difference between the basic value of packet 2 and the basic value of packet 1, that is, 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, intermediate unit 20 determines that authentication has been established.

  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. Further, the basic values of packet 1 and packet 2 may be selected within a numerical range that does not overflow. Further, in the arithmetic processing using the packet 1 and the packet 2, it may be calculated as an unsigned operation. Furthermore, the correlation condition may be changed for each authentication process in order to increase the authentication strength. For example, the first correlation condition may be “+2”, the second correlation condition may be “+5”, the third correlation condition may be “+1”, and the like. However, when applying the correlation change rule as described above, either the main control unit 10 and the intermediate unit 20 share in advance, or a means or process for notification is prepared. .

  In addition, simply transmitting continuous packet information from the main control unit 10 to the intermediate unit 20 may cause a third party to analyze the packet information difference. 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 preprocessing to the basic value may be performed only on one of the two pieces of packet information output at an output timing set in advance at an arbitrary interval such as packet 1 and packet 2. , May be applied to both.

  In the first embodiment, the intermediate unit 20 switches the expected value based on the number of combinations when the inspection value generation method in the main control unit 10 is switched as described above. For example, when the number of divisions and the number of connections are odd numbers, the main control unit 10 corresponds to a test value generation method, and the intermediate unit 20 corresponds to an expected value used for individual authentication corresponding to a semi-group operation used at the time of test value generation. When the number of divisions and the number of connections is an even number, the test value generation method of the main control unit 10 and the expected value of the intermediate unit 20 are continuously used for the expected values. 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 the authentication is successful. Therefore, the fraudster cannot know the number of divisions and the number of combinations, and cannot know the test value generation method and the switching timing of expected values. Thereby, it is possible to prevent the inspection value from being illegally generated by an unauthorized person.

  The means for executing the operation authentication process can correspond to, for example, the action authentication means 23 shown in FIG.

[5] Generation of intermediate processing information The intermediate unit 20 is the same as when the authentication data obtained by the authentication processing of [3] and [4] or authentication data is generated by the main control unit 10 for the authentication result. What has been subjected to encryption processing is generated as intermediate processing information.

≪Calculation example of intermediate processing information generation≫
An example of calculation for generating the intermediate processing information 305 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 the intermediate processing information 305 to a normal control signal including control command data 301 and accompanying data 302, and generates a control signal 321 with intermediate processing information.

[7] Transmission of control signal The intermediate unit 20 transmits a control signal 321 with intermediate processing information to the effect control unit 203. Details of processing related to the control signal with intermediate processing information will be described later.

  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. In addition, when the 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 performs an intermediate process such as authentication for each authentication data. Processing is performed to generate intermediate processing information 305. For example, a control signal with intermediate processing information 321 shown in FIG. 7B is generated and transmitted to the effect control unit 203. Not only the control signal 321 with intermediate processing information configured in the order shown in FIG. 7 (2) but also the intermediate processing information 305 as the head of the control signal as shown in FIGS. 7 (3) and (4). Alternatively, it may be inserted between the control command data 301 and the accompanying data 302.

  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.

Usually, 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, and reads necessary image data from the ROM 203b to the VRAM 203d. 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. If a game ball has entered the mouth 120, the main control unit proceeds to step S8.

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

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

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

  In step S13, the main control unit 10 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 | presentation control part 203 will progress to step S44.

  In step S44, the effect control unit 203 transmits to the symbol display unit 104 or the lamp control unit 205 a round-by-round processing command corresponding to the received round-by-round jackpot command, and then proceeds to step S45. In step S45, it is determined whether 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, when the output control command is a predetermined control command, the main control unit 10 generates individual authentication data and operation authentication data for the number of divisions using a predetermined program code. The authentication data is added to the control command and transmitted to the intermediate unit 20.

  The intermediate unit 20 authenticates whether or not the main control unit 10 is a regular main control unit using the test value and each code obtained from each authentication data received from the main control unit 10. 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, authentication processing 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 control command transmitted from the main control unit 10 is authenticated. By this authentication process, the fraudulent act can be detected and fraud to the pachinko gaming machine 1 can be prevented, and the pachinko gaming machine 1 caused by electrical noise or mechanical vibration applied from the outside can be prevented. Malfunctions can 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 an example of processing related to authentication by the main control unit 10. The main control unit 10 waits for the transmission timing of the control signal with authentication data while transmitting a normal control signal (step S61) (step S62). When the transmission timing of the control signal with authentication data comes (step S62: YES), the main control unit 10 determines the number of divisions (step S63). The method for determining the number of divisions is arbitrary. The number of divisions may be determined before the transmission timing of the control signal with 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, calculates a test value (step S64), On the other hand, encryption processing is performed to generate individual authentication data (step S65). By this process, test values and individual authentication data for the number of divisions are generated. The generation of the inspection value may be performed before the transmission timing of the control signal with authentication data. Here, the method of generating inspection values (such as the type of calculation used for generation) is determined at the time of previous authentication data transmission. The method for generating the first inspection value is determined in advance as an initial value.

  Subsequently, the main control unit 10 determines a code to be used as operation authentication data from the operation code, the relative time code, and the synchronization code based on the number of divisions determined in step S63 (step S66). Then, the determined code is generated, and operation authentication data is generated based on the code (step S67). Note that step S66 and step S67 are interchanged to generate all the operation code, relative time code, and synchronization code, and select and use only the code determined to be used as operation authentication data. May be.

  Next, the main control unit 10 adds the generated individual authentication data and operation authentication data to the control command data to generate a control signal with authentication data (step S68), and sends the control signal with authentication data to the intermediate unit 20. Transmit (step S69). The control command for adding the authentication data is not particularly limited and may be an arbitrary control command. The control signal with authentication data may be transmitted continuously, or may be transmitted by mixing with a normal control signal. Further, the transmission order of the authentication data is also arbitrary. The main control unit 10 returns to step S69 and continues to transmit the control signal with authentication data until all the authentication data generated in step S65 and step S67 is transmitted (step S70: NO). When all the authentication data is transmitted (step S70: YES), the process according to this flowchart is terminated.

  The main control unit 10 may add individual authentication data and operation authentication data to the control command only when a predetermined control command is transmitted to the intermediate unit 20. In this case, since the authentication process is performed only when a predetermined control command is transmitted, the rate at which the processing load on the main control unit 10 and the effect control unit 203 increases due to the authentication process can be suppressed. 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, it is possible to reduce the possibility that individual authentication data and operation authentication data are extracted from the control signal. Further, even if individual authentication data or operation authentication data is extracted from the control signal, the number of samples that can be acquired is small, so that the risk of analyzing individual authentication data or operation authentication data 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 individual authentication data or operation authentication data is added to the control command when sending the loss command data. If so, the flow from the lottery to the authentication process can be regarded as a basic form of the process 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.

  Next, the authentication process of the main control unit 10 by the intermediate unit 20 will be described. Hereinafter, as an example, an example in which an authentication data-added control signal 310 including the individual authentication data 303 and the operation authentication data 304 as illustrated in FIG. 6B is transmitted from the main control unit 10 will be described. FIG. 15 is a flowchart illustrating an example of processing related to authentication of the main control unit 10 by the intermediate unit 20. In the flowchart of FIG. 15, when the intermediate unit 20 first receives a normal control signal from the main control unit 10, the intermediate unit 20 receives the control signal with authentication data from the main control unit 10 while transmitting it directly to the effect control unit 203. (Step S71). Here, the determination of whether or not the authentication data is included in the control signal is, for example, whether or not the data amount of the control signal is larger than that of the normal control signal, It is performed by determining whether or not any bit constituting 302 or identification data (not shown) provided separately indicates that authentication data is included.

  When the control signal with authentication data is received from the main control unit 10 (step S71: YES), the intermediate unit 20 extracts the authentication data contained in the received control signal with authentication data, performs a decryption process, and performs an inspection. A value and a code are generated (step S72). The intermediate unit 20 stores the generated inspection value in the inspection value memory and stores the generated code in the code memory (step S73).

  Next, the intermediate unit 20 performs a semi-group operation (joining process) on all the inspection values in the inspection value memory (step S74). Here, the type of semi-group operation performed in step S74 is determined when the previous authentication data is received. In addition, the type of the first half-group operation is determined in advance as an initial value. If there is one inspection value in the inspection value memory, the process proceeds to step S75 without performing the combining process.

  Then, the intermediate unit 20 compares the operation result (combination result) with the expected value of the stored test value, and determines whether or not the combination result and the expected value match (step S75). As a result, when the combined result matches the expected value (step 75: YES), the intermediate unit 20 makes the main control unit 10 authenticate successfully (step S76). Then, when the individual authentication of the main control unit 10 is successful, the intermediate unit 20 specifies the number of divisions (number of connections) based on the authentication result (step S77).

  Subsequently, the intermediate unit 20 specifies a code that is used as operation authentication data based on the number of inspection values (the number of combinations) subjected to the combination process when the authentication is successful (step S78). Then, the intermediate unit 20 authenticates the operation of the main control unit 10 based on whether or not the information indicating the continuity of the operation of the main control unit 10 included in the identified code satisfies a predetermined condition (step S79). Specifically, when the operation code is generated using the function number as the authentication using the operation code, a collation process is performed to determine whether a plurality of operation authentication data are arranged in a normal order. In addition, when the operation code is generated using the number of authentications, it is determined whether or not the expected value for operation authentication, which is the value obtained by performing the same encryption processing as the encryption processing applied to the number of authentications, matches. Perform the matching process. On the other hand, authentication using a relative time code is performed by determining whether or not the value of the received relative time code increases in time series. The 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.

  In this way, when the operation authentication for the main control unit 10 is successful (step S80: YES), the intermediate unit 20 authenticates the main control unit 10 as a regular main control unit (step S81), and performs an inspection. The data in the value memory and the code memory are deleted (step S82). Moreover, the intermediate | middle part 20 transfers to step S86, when the operation | movement authentication with respect to the main control part 10 has not succeeded (step S80: NO).

  After the processing in step S82, the intermediate unit 20 generates intermediate processing information 305 from the authentication result (step S83). Next, the intermediate unit 20 includes a control signal (control signal with intermediate processing information) including the control command data 301 and the accompanying data 302 included in the control signal, and the intermediate processing information 305 obtained in the process of step S83. Is generated and transmitted to the effect control unit 203 (step S84), and the processing according to this flowchart ends.

  Further, in step S75, when the calculation result of the test value does not match the expected value (step S75: NO), the intermediate unit 20 continues to step S71 until receiving a predetermined number or more of individual authentication data (step S85: NO). Return to and repeat the join process. When the authentication data of a predetermined number or more is received (step S85: YES), the intermediate unit 20 makes the authentication to the main control unit 10 unsuccessful (step S86), and proceeds to step S83. Here, the predetermined number is an arbitrary number within a range not less than the current 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.

  As described above, the intermediate unit 20 performs authentication processing twice by using two types of authentication data, that is, individual authentication data and operation authentication data, thereby improving the strength of authentication and making unauthorized use of unauthorized control commands. It is possible to prevent the processing from being executed. Further, by authenticating the operation sequence of the main control unit 10, the continuity of the operation of the main control unit can be authenticated, and for example, an unauthorized control board equipped with a signal switching circuit or the like can be detected.

  In the first embodiment, after the authentication process is successful, the data in each memory is deleted in step S82. 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.

  Here, the intermediate unit 20 may add the intermediate processing information 305 to the control command only when a predetermined control command is transmitted to the effect control unit 203. In this case, since the authentication process of the main control unit 10 or 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. .

  Further, since only the intermediate unit 20 performs authentication processing such as authentication data decryption, verification between the inspection value and expected value, and authentication of each code, the processing load on the CPU 203a constituting the effect control unit 203 increases. There is no. 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.

  When the control signal 311 with individual authentication data to which the operation authentication data 304 is not added as shown in FIG. 6 (3) is newly received, the intermediate unit 20 generates a code in step S72, In step S78, the code cannot be specified. Therefore, for example, if the code cannot be specified in step S78, the process returns to step S71. Then, when processing the operation authentication data after the next time, the processing related to the individual authentication data in steps S72 to S77 may be omitted.

  When the control signal 312 with operation authentication data to which the individual authentication data 303 is not added as shown in FIG. 6 (4) is newly received, the intermediate unit 20 generates a test value in step S72. In step S76, the expected value cannot be matched. Therefore, for example, the process proceeds to step S71 via step S85, and a code is generated in step S72, and stored in the code memory in step S73. And in performing the process after the next time, you may make it abbreviate | omit the process regarding the operation | movement authentication data of step S72-S73.

  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 S91). 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 S91 will be "YES", and the production | presentation control part 203 will progress to step S92.

  In step S92, 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 S92 is “YES”, that is, if the intermediate control information 305 is included in the received control signal, the effect control unit 203 proceeds to step S93. 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 S93, 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 S94.

  In step S94, 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 S94 is “YES”, that is, if the extracted authentication result indicates that the authentication is successful, the effect control unit 203 proceeds to step S95. In addition, when the determination result of step S92 is “NO”, that is, when the received control signal does not include the intermediate processing information 305, that is, when it is a normal control signal, the effect control unit 203 Proceed to step S95.

  In step S95, the effect control unit 203 performs a process based on the control command data 301 and the accompanying data 302, and then ends the series of processes. On the other hand, if the determination result in step S94 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 S96. In step S96, 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 the illegal act. After the transmission to the center control device or the like, the series of processing ends. In the process of step S96, 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 process of selecting and specifying the code used as the operation authentication data 304 among the processes shown in FIGS. 14 and 15 will be described. FIG. 17 is a processing sequence illustrating an example of a mutual relationship between processes executed by the main control unit 10 (authenticated person) and the intermediate unit 20 (authenticated person). In FIG. 17, as a code selection example based on the number of divisions, it is assumed that a code to be used is selected according to selection example 1 (X = 3 here) shown in FIG.

  First, the main control unit 10 proceeds to the process of step S101, determines the number of divisions used for the current authentication process by an arbitrary method, and then proceeds to step S102. For example, the main control unit 10 determines that the current division number is 3 as a default. In step S102, 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 inspects the program code stored in each block. After the value is generated, the process proceeds to step S103.

  In step S103, the main control unit 10 generates the individual authentication data 303 by performing encryption processing on the inspection value, and then proceeds to step S104. In step S104, a code to be used as the operation authentication data 304 is determined based on the number of divisions, and then the process proceeds to step S105. Specifically, the number of divisions (in this case “3”) is divided by the value of X (in this case “3”), and the code is determined by the remainder value. In this case, since the remainder obtained by dividing 3 by 3 is 0, the main control unit 10 determines (selects) the operation code as the operation authentication code.

  Then, the operation authentication data 304 is generated by performing encryption processing on the operation code selected in step S104 (step S105), and the process proceeds to step S106. In step S106, the main control unit 10 transmits the control signal with authentication data 310 including the individual authentication data 303 and the operation authentication data 304 to the intermediate unit 20, and then proceeds to step S107.

  Thereby, the intermediate part 20 receives the control signal 310 with authentication data transmitted from the main control part 10 (step S107), and then proceeds to step S108. In step S108, the intermediate unit 20 extracts the individual authentication data 303 and the operation authentication data 304 from the control signal with authentication data 310, and then proceeds to step S109. In step S109, the intermediate unit 20 obtains a test value and a code by performing decryption processing on the individual authentication data 303 and the operation authentication data 304, and stores them in the test value memory and the code memory. Proceed to step S110.

  In step S110, the intermediate unit 20 performs a combining process on the acquired inspection value, and then proceeds to step S111. In step S111, the intermediate unit 20 checks the combined result with the expected value, determines that the authentication is successful when the combined result and the expected value match, and determines that the combined result and the expected value do not match. After determining that the authentication is not successful, the process proceeds to step S112. In this case, when the joining process is performed using three inspection values, the joining result and the expected value should match (joining number = 3).

  In step S112, the intermediate unit 20 specifies the type of code used as the operation authentication data based on the number of combinations, and proceeds to step S113. In this case, since the remainder obtained by dividing 3 which is the number of connections by 3 which is X is 0, the operation authentication data 304 is specified as an operation code (see FIG. 5). In step S113, the operation order of the main control unit 10 is authenticated by an authentication method corresponding to the operation code. This is the flow of code selection / specification processing.

  Next, in the second authentication process, the main control unit 10 proceeds to the process of step S114, determines again the number of divisions used for the current authentication process by an arbitrary method, and then proceeds to step S115. For example, the main control unit 10 determines that the current number of divisions is four. In step S115, the main control unit 10 divides a predetermined program code stored in the storage area of the ROM 10b into four blocks (storage areas), and inspects the program code stored in each block. After the value is generated, the process proceeds to step S116.

  In step S116, the main control unit 10 generates the individual authentication data 303 by performing encryption processing on the inspection value, and then proceeds to step S117. In step S117, after determining (selecting) a code to be used as the operation authentication data 304 based on the number of divisions, the process proceeds to step S118. Specifically, the number of divisions (in this case “4”) is divided by the value of X (in this case “3”). Since the remainder is 1, the main control unit 10 determines (selects) the relative time code as the code for operation authentication. In step S118, the operation authentication data 304 is generated by performing encryption processing on the determined code, and then the process proceeds to step S119. In step S119, the main control unit 10 transmits the control signal with authentication data 310 including the individual authentication data 303 and the operation authentication data 304 to the intermediate unit 20, and then proceeds to step S120.

  Thereby, the intermediate part 20 receives the control signal 310 with authentication data transmitted from the main control part 10 (step S120), and then proceeds to step S121. In step S121, the intermediate unit 20 extracts the individual authentication data 303 and the operation authentication data 304 from the control signal with authentication data 310, and then proceeds to step S122. In step S122, the intermediate unit 20 obtains a test value and a code by performing decryption processing on the individual authentication data 303 and the operation authentication data 304, and stores them in the test value memory and the code memory. Proceed to step S123.

  In step S123, the intermediate unit 20 performs a combining process on the acquired inspection value and code, and then proceeds to step S124. In step S124, the intermediate unit 20 compares the combined result with the expected value, determines that the authentication is successful when the combined result and the expected value match, and determines that the combined result does not match the expected value. After determining that the authentication is not successful, the process proceeds to step S125. In this case, when the joining process is performed using four inspection values, the joining result and the expected value should match (joining number = 4). In step S125, the intermediate unit 20 specifies the type of code used as the operation authentication data 304 based on the number of combinations, and proceeds to step S126. In this case, since the remainder obtained by dividing 4 which is the number of connections by 3 which is X is 1, the operation authentication data 304 is specified as a relative time code (see FIG. 5). In step S113, the operation order of the main control unit 10 is authenticated by an authentication method corresponding to the operation code.

  In this case, the main control unit 10 divides a predetermined program code stored in the ROM 10b, and generates an authentication data generation method (operation authentication data 304 selection method and encryption method) at the next authentication based on the number of divisions. Etc.). Since the number of divisions is a value that only the main control unit 10 knows, the fraudster cannot know the switching timing of selection of authentication data. For this reason, it is possible to detect the cheating and the malfunction of the gaming machine. Note that only the encryption method may be switched without switching the inspection value generation method based on the number of divisions.

Note that the intermediate unit 20 may perform the authentication process using the individual authentication data 303 at the time of receiving a plurality of authentication data, instead of performing the authentication process every time the authentication data is received. In this case, for example, when the first authentication data is received together with the first control command data and the first associated data of the first control command, the intermediate unit 20 does not perform the authentication process and performs the first control command. Processing based on one control command data and first accompanying data is performed. When the intermediate unit 20 receives the second authentication data together with the second control command data and the second associated data of the second control command, the intermediate unit 20 receives the second control command data and the second control command data of the second control command. Before performing the process based on the second accompanying data, the authentication process using the first authentication data is performed. At this time, the intermediate unit 20 may perform the authentication process using both the first authentication data and the second authentication data.
Further, the authentication data may be generated including the control command data 301 and the accompanying data 302 transmitted this time. As a result, it is possible to prevent unauthorized use and malfunction by preventing unauthorized use of authentication data by the main control unit, and to prevent execution of unauthorized control commands due to unauthorized actions and malfunctions. Can do.

  As described above, in the pachinko gaming machine 1 according to the first embodiment, the authentication data for authenticating the validity of the main control unit 10 is generated at the timing of transmitting the control command, and the generated authentication data is used. The authentication process was performed. By performing such an authentication process, the processing load on the main control unit 10 and the effect control unit 203 increases only during the period when the control command is received, and the main control unit 10 and the effect control unit The rate at which the processing load 203 increases can be suppressed.

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 10a constituting the main control unit 10 and the storage capacity of the ROM 10b and RAM 10c constituting the main control unit 10 are the processing capacity of the CPU 203a constituting the effect control unit 203 and the ROM 203b and RAM 203c constituting the effect control unit 203. When there is a margin in comparison with the storage capacity, the main control unit 10 intermediates authentication data (individual authentication data and operation authentication data) obtained by subjecting the inspection value and code to complex or advanced encryption processing. The intermediate unit 20 performs a relatively simple or low-level encryption process on the authentication result obtained by authenticating the main control unit 10 using the inspection value and code obtained from the received authentication data. The obtained intermediate processing information 305 is transmitted to the effect 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 203a constituting the effect control unit 203 and the storage capacity of the ROM 203b and RAM 203c constituting the effect control unit 203 are the processing capacity of the CPU 10a constituting the main control unit 10, and the ROM 10b and RAM 10c constituting the main control unit 10. If there is a margin in comparison with the storage capacity, the main control unit 10 can obtain each inspection value and each code as individual authentication data and operation authentication data as they are, or by performing relatively simple or low-level encryption processing. The obtained individual authentication data and operation authentication data are transmitted to the intermediate unit 20, and the intermediate unit 20 authenticates the main control unit 10 using each test value and each code obtained from the received individual authentication data and operation authentication data. The authentication result is subjected to complex or advanced re-encryption processing, or the individual authentication data and operation authentication data The intermediate control information 305 obtained by performing an intermediate operation for performing a more complicated or advanced re-encryption process after performing a decryption process on each check value and each code obtained from 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 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 constituting the main control unit 10 and the effect control unit 203 and the storage capacity of the ROMs 10b and 203b, the RAM 10c and the RAM 203c, respectively. Although there is no difference, when all or a 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 (such as version upgrade), The same applies to a case where a formal difference occurs between the main control unit 10 and the effect control unit 203 in a data structure such as an intermediate calculation result.

<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 the target of test value generation. 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. The main control unit 10 determines the amount of data until, for example, the test value is generated using all of the predetermined program code 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 semi-group operation for each data block, and generates 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 inspection 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 inspection value until the generation of the inspection 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 inspection values are generated (that is, how many divisions are to be made) depends on the generation of inspection values using all program codes in a predetermined area of the ROM 10b. I do not know until completion.

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

An example in which the test value is generated by the method A using addition as the semi-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 for generating the first inspection value is determined to be 4 bytes, 4 bytes of program code (“0x01”, “0x02”, “0x03”, “0x04”) are divided into first blocks 400a. Next, the program code “0x01”, “0x02”, “0x03”, “0x04” stored in the first block 400a is added to obtain the first inspection value “0x0A”.

  Subsequently, when it is determined that the data amount used for generating the second inspection value is 3 bytes, the program code stored in the program code storage area 400 excluding the program code stored in the first block 400a A 3-byte program code (“0x05”, “0x06”, “0x07”) is divided from the code to form a second block 400b. Next, the program code “0x05”, “0x06”, “0x07” stored in the second block 400b is added to obtain the second inspection value “0x12”.

  Subsequently, when it is determined that the amount of data used for generating the third inspection value is 7 bytes, among the program codes stored in the program code storage area 400, the programs stored in the first block 400a and the second block 400b Since the program code excluding the 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 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 has generated the test value using all the 12 program codes stored in the program code storage area 400, the main control unit ends the generation of the 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 the data amount is determined every time a test value is generated and a predetermined program code is divided will be described.

  The main control unit 10 waits for the transmission timing of the control signal with authentication data while transmitting a normal control signal (step S130) (step S131). When the transmission timing of the control signal with authentication data comes (step S131: YES), the main control unit 10 determines the data amount of the program code used for generating the inspection value and the code (step S132). The method for determining the data amount is arbitrary. Further, the data amount may be determined before the transmission timing of the control signal with authentication data.

  Next, the main control unit 10 reads out the program code having the data amount determined in step S132, for example, from the top of the program code storage area 400, performs a semi-group operation, and calculates a test value (step S133). The value is subjected to encryption processing to generate individual authentication data (step S134). By this process, test values and individual authentication data for the number of divisions are generated. The generation of the inspection value may be performed before the transmission timing of the control signal with authentication data. Here, the method of generating inspection values (such as the type of calculation used for generation) is determined at the time of previous authentication data transmission. The method for generating the first inspection value is determined in advance as an initial value.

  Next, the main control unit 10 returns to step S132 until the test value is generated using all data in the program code storage area 400 (step S135: NO), and the above processing is repeated. Here, “using all data in the program code storage area 400” means that the data in the program code storage area 400 is used without omission and duplication. The main control unit 10 reads out data in order from the top of the program code storage area 400, for example, and uses it to generate inspection values. When generating the second and subsequent test values, the test value is generated by reading the data written in the area next to the program code used to generate the previous test value by the amount determined in step S132. Note that when the last test value is generated, the data amount determined in step S132 may be insufficient, but the main control unit 10 generates the test value using only the program data that can be acquired.

  When the test value is generated using all the data in the program code storage area 400 (step S135: YES), the main control unit 10 operates based on the number of individual authentication data generated in step S134, that is, the number of divisions. A code used as operation authentication data is determined from the code, the relative time code, and the synchronization code (step S136). Then, operation authentication data is generated based on the determined code (step S137). Note that step S136 and step S137 may be interchanged to generate all the operation code, relative time code, and synchronization code, and only the code determined to be used as operation authentication data may be used.

  Next, the main control unit 10 adds the generated individual authentication data and operation authentication data to the control command data (step S138), and transmits a control signal with authentication data to the intermediate unit 20 (step S139). Then, the main control unit 10 returns to step S139 and repeats the transmission of the control signal with authentication data until all the individual authentication data and the operation authentication data are transmitted (step S140: NO). When all the authentication data has been transmitted (step S140: YES), the processing according to this flowchart is terminated.

  Here, the control command for adding the authentication data is not particularly limited and may be an arbitrary control command. The control signal with authentication data may be transmitted continuously, or may be transmitted by mixing with a normal control signal. In addition, the authentication data is not transmitted immediately after it is generated, but is generated after all the authentication data is generated (that is, after the authentication data is generated using all the program codes in the program code storage area 400). Data transmission may be started.

  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 authentication data from the control signal with authentication data transmitted from the main control unit 10, performs authentication processing using the authentication data, generates intermediate processing information using the authentication result, A control signal with processing information is transmitted to the effect control unit 203. 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 code selection / specification process among the processes shown in FIGS. 18 and 15 will be described. FIG. 19 is a processing sequence illustrating an example of a mutual relationship between processes executed by the main control unit 10 (authenticated person) and the intermediate unit 20 (authenticated person). In FIG. 19, as a code selection example based on the number of divisions, a code to be used is selected according to selection example 1 (X = 3 in this example) shown in FIG. In this sequence diagram, for convenience of explanation, the data amount used for generating the inspection value is collectively determined. However, the data amount may be determined every time the inspection value is generated.

  First, the main control unit 10 determines a data amount used for generating authentication data by an arbitrary method. For example, if the total amount of data is 12 bytes, and the amount of data used to generate inspection values is 4 bytes, 3 bytes, and 5 bytes, respectively, three inspection values are generated, and the number of divisions = 3 ( Step S140). The main control unit 10 reads out 4-byte, 3-byte, and 5-byte program codes sequentially from the top of the program code storage area 400, and generates a test value using each program code (step S142). The main control unit 10 performs an encryption process on the inspection value to generate individual authentication data (step S143). Further, a code is selected according to the number of divisions (step S144), and the selected code is subjected to encryption processing to generate operation authentication data (step S145). Thereafter, a control signal with authentication data including the individual authentication data and the operation authentication data is transmitted to the intermediate unit 20 (step S146).

  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 S147). Then, the individual authentication data and the operation authentication data are extracted from the control signal with authentication data (step S148), and the inspection value and the code are obtained by performing the decryption process (step S149). The intermediate unit 20 performs a combination process on the acquired inspection value (step S150), and collates the combination result with the expected value. If it matches the expected value, the intermediate unit 20 succeeds in authentication with the main control unit 10 (step S151). In this case, when combining processing is performed using three inspection values, it should match the expected value (number of connections = 3).

  The intermediate unit 20 identifies the type of code used as operation authentication data based on the number of connections (step S152), and authenticates the operation sequence of the main control unit 10 using an authentication method corresponding to the identified code ( Step S153). This is the flow of code selection / specification processing.

  Subsequently, in the second processing, the main control unit 10 again determines the data amount used for generating the authentication data by an arbitrary method. For example, if the amount of data used to generate the inspection value is 4 bytes, 2 bytes, 3 bytes, and 3 bytes, respectively, four inspection values are generated, and the number of divisions is 4 (step S154). The main control unit 10 reads out 4-byte, 2-byte, 3-byte, and 3-byte program codes in order from the top of the program code storage area 400, and generates a test value using each program code (step S155). The main control unit 10 performs an encryption process on the inspection value to generate individual authentication data (step S156). Further, a code is selected according to the number of divisions (step S157), and the selected code is subjected to encryption processing to generate operation authentication data (step S158). Thereafter, a control signal with authentication data including individual authentication data and operation authentication data is transmitted to the intermediate unit 20 (step S159).

  Subsequently, the intermediate unit 20 receives the control signal with authentication data transmitted from the main control unit 10 (step S160), and extracts the individual authentication data and the operation authentication data (step S161). Then, a decryption process is performed to obtain a check value and code (step S162), and a join process is performed on the obtained check value (step S163). When the combined result matches the expected value, the intermediate unit 20 succeeds in authentication with the main control unit 10 (step S164). In this case, when the joining process is performed using four inspection values, it should match the expected value (number of joins = 4). Further, the intermediate unit 20 identifies the type of code used as the operation authentication data based on the number of connections (step S165), and authenticates the operation sequence of the main control unit 10 using the authentication method corresponding to the identified code. (Step S166).

  As described above, in the pachinko gaming machine 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 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.

  In the pachinko gaming machine of the third embodiment, the intermediate unit 20 and the effect control unit 203 are configured by a single piece of software, so that the following effects can be obtained in addition to the effects obtained in the first and second embodiments. It is done.

1. Parallel development and information security improvement When the production control unit 203 and the intermediate unit 20 are separated and independent on the software configuration, the production control unit 203 and the intermediate unit 20 can be individually developed in parallel, Thereby, for example, the following effects can be obtained.

[1] Since the production control unit 203 and the intermediate unit 20 can be designed and developed at the same time, the product development period can be shortened compared to the case where parallel development is impossible.
[2] Because the production control unit 203 and the intermediate unit 20 can have independent development systems, confidential business information (for example, authentication) when performing design and manufacturing verification of the production control unit 203 and the intermediate unit 20 The possibility of outflow of processing methods, etc. related to games, etc.) outside the respective development system can be reduced.

2. Ease of introduction of authentication function and portability to other models Since the authentication process of the intermediate unit 20 is independent of the existing game process, the authentication information between the authentication process of the intermediate unit 20 and the existing game process Transmission can be performed using an interface provided for existing game processing. Therefore, it becomes easy to introduce an authentication function.

  Further, when designing and developing a new model of a pachinko gaming machine, there is a high possibility that the difference between the function of the new model of the pachinko gaming machine and the function of the previous model is not so much related to the implementation of the intermediate unit 20. Therefore, there is a high possibility that a slight design change is required when the intermediate unit 20 is shifted from the previous model to the new model.

3. Ease of Verification When the production control unit 203 and the intermediate unit 20 are separated and independent in terms of software configuration, the production control unit 203 and the intermediate unit 20 can be individually verified. Therefore, compared with the case where verification is performed for the production control unit 203 and the intermediate unit 20 that are not separated, each function is closed with a narrow function, so that verification can be performed in a short time and with a small number of people. .

4). Changeability of authentication method When the authentication method is changed or the authentication algorithm is upgraded, only the main control unit 10 and the intermediate unit 20 need to change or upgrade, and the processing related to the authentication of the effect control unit 203 There is no need to change

5. Even if it is not possible to provide a CPU or dedicated integrated circuit separate from the effect control unit 203 as authentication hardware, an authentication function can be easily added by software.

6). Reduction of processing load of the effect control unit 203 When the authentication function to be implemented in the intermediate unit 20 is implemented by software of the effect control unit 203, by adding an authentication function to the existing game processing of the effect control unit 203, the effect control unit 203 The processing load increases. Therefore, it is conceivable to use a dual core CPU as the CPU constituting the effect control unit 203. 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 effect control unit 203 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 part 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.

  In addition, in the pachinko gaming machines according to the first to third embodiments, it is assumed that an operation code, a relative time code, and a synchronization code are generated using a predetermined generation method, and about switching about specific information in each code Although not mentioned in particular, information for generating each code (for example, in the case of an operation code, a function number, the number of authentications, etc.) may be switched depending on the number of divisions, etc. 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 the inspection value from being illegally generated by an unauthorized person.

  Moreover, in the pachinko gaming machine according to the first to third embodiments, for example, when a function number is used as an operation code, the function number is used for each process for executing a predetermined function of a program executed by the main control unit 10. You may 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.

  Moreover, although the pachinko gaming machine according to the first to third embodiments has been described as adding at least one of individual authentication data and operation authentication data to the control command when transmitting the control command, the game according to the present invention The machine is not limited to this. For example, a control signal composed only of authentication data may be generated and output at a predetermined timing.

  Furthermore, the inspection value generation method in the main control unit 10 may be switched according to the number of divisions, for example. In this case, the main control unit 10 can be configured to select one half-group operation used for generating the next inspection value from a plurality of half-group operations based on the number of divisions. On the other hand, when the inspection value generation method in the main control unit 10 is switched, the intermediate unit 20 switches the expected value based on the number of connections. 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. Note that 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. Here, the division number is a value that only the main control unit 10 knows, and the intermediate unit 20 can know the value as the number of couplings only when the 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 test value generation method. Thereby, it is possible to prevent the inspection value from being illegally generated by an unauthorized person.

In each of the above embodiments, the present invention is applied to a pachinko gaming machine. However, the present invention is not limited to this, and the present invention is not limited to a pachinko gaming machine such as a sparrow ball gaming machine or an arrangement ball. The present invention can also be applied to other gaming machines such as a revolving type gaming machine such as a gaming machine or a slot machine. Even in these gaming machines, the same effects as those of the above-described embodiments can be obtained by configuring similarly to the above-described embodiments.
In addition, each of the above embodiments can utilize each other's technology as long as there is no particular contradiction or problem in the purpose, configuration, or the like.
