Description

  The present invention relates to an electronic device, a gaming machine, and an electronic device authentication method that include a plurality of substrates and authenticate communication between these substrates.

  Conventionally, in gaming machines having a plurality of boards, various techniques have been proposed for preventing fraud on these boards. An example of a gaming machine provided with a plurality of boards is a pachinko gaming machine. The pachinko gaming machine includes a main control board that controls the operation of the entire gaming machine, and a controlled board (peripheral board) that performs the operation of each part of the gaming machine. The main control board outputs a control signal including control command information to the peripheral board, and the other peripheral boards have a function of executing an operation according to the control signal transmitted from the main control board.

  In the case of a gaming machine having such a configuration, the illegality with respect to the main control board includes, for example, replacing a regular main control board with an illegal control board, or altering a program code that defines processing performed by the main control board. There is a technique. In order to prevent such fraud, for example, a technique has been proposed in which program data recorded in a ROM mounted on the main control board is checked by a ROM checker to prevent illegal exchange of the ROM ( For example, see the following Patent Document 1.)

  Further, Patent Document 2 transmits control command information from the main control board to the sub control board, and further transmits a state monitoring command for monitoring the communication state of the control command information in a predetermined communication path. Describes a configuration for verifying the validity of control command information using a status monitoring command and stopping control of a control target when it is determined that there is an error.

  However, in the case of Patent Document 1 described above, the alteration of the program data can be detected. However, if an unauthorized control board is connected between the regular main control board and the controlled board, There has been a problem that it is not possible to prevent unauthorized control by an unauthorized control signal that is output.

  Further, as in Patent Document 2 described above, when a state monitoring command different from the control command information is transmitted from the main control board to the controlled board, the gaming machine may be cheated ("got" action). Since the state monitoring command is easily analyzed illegally by the unauthorized control board or the like interposed between the main control side and the controlled side, if the analysis cannot be made difficult, It was difficult to realize with a machine. Further, if complicated encryption is performed at the time of transmission, there is a problem that processing of each of the regular main control board and the controlled board becomes complicated and processing load increases. There is also a problem peculiar to gaming machines that the processing load on the main control unit cannot be increased due to the authentication process.

  Furthermore, recently, in order to improve the interest of the game, there is a tendency for various effects to appeal to the visual and auditory senses of the player at the time of reach or jackpot. Therefore, if the CPU on the peripheral part (peripheral board) side tries to execute the authentication process in addition to the existing process, the processing load of the CPU increases and the processing speed decreases, and the display for the production is smooth. In the worst case, the authentication process itself could not be added.

According to the authentication method for an electronic device of the present invention described in claim 4 above, for example, a control command for each of a plurality of types of control command information in the electronic device between the design and manufacture of the electronic device. A command value for identifying information and specifying one individual identification value by calculation with a random value can be set. When the main control unit transmits the control command information to the peripheral unit via the intermediate unit according to the operation of the electronic device, the main control unit generates history data indicating the history by the history generation method. The main control unit calculates a command value and a random number value included in one control command information transmitted to the peripheral part via the intermediate part of the command values of the control command information by a predetermined calculation method, One individual identification value corresponding to the result is extracted from three or more types of individual identification values stored in the individual identification value storage means. The main control unit can generate authentication information by adding the extracted individual identification value to the history data by a predetermined addition method, and transmit the authentication information to the peripheral unit. On the other hand, when the intermediate unit receives the control command information from the main control unit, the intermediate unit transfers the control command information to the peripheral unit, and stores the intermediate side history data indicating the history of the control command information received from the main control unit. It is generated by the same history generation method as that of the copy. The intermediate unit specifies an individual identification value to be extracted from the three or more types of individual identification values based on the command value of the received control command information. The intermediate unit extracts the history data for authentication from the authentication information received from the main control unit based on the expected value that matches the identified individual identification value and the additional method that is the same as the main control unit. The intermediate unit generates intermediate authentication result data indicating an authentication result of the main control unit determined based on whether or not the extracted authentication history data matches the intermediate history data, and transmits the generated intermediate authentication result data to the peripheral unit Can do. On the other hand, the peripheral unit can perform a predetermined process in the electronic device based on the control command information received from the main control unit according to the intermediate authentication result data received from the intermediate unit.

As described above, according to the present invention, the main control unit uses the command value and random number value included in one control command information transmitted to the peripheral part through the intermediate part of the command values of the existing control command information. By simply calculating, one individual identification value corresponding to the calculation result is extracted from three or more types of individual identification values, and authentication information in which the extracted individual identification value is added to the history data is generated. Since the individual identification value added to the history data irregularly changes depending on the random value even if the intermediate unit uses the history data of the authentication information for authentication of the main control unit. Therefore, it can be expected to prevent unauthorized analysis of authentication information. In addition, the intermediate unit extracts the authentication history data from the authentication information using only the expected value corresponding to the command value of the control command information with respect to the three or more types of expected values. Since the main control unit is authenticated based on the determination result of whether or not the side history data match, the pattern to be extracted by the main control unit can be changed by different types of command values. The main control unit does not need to determine (recognize) the change, and the intermediate unit can bear the processing related to the authentication of the main control unit. Therefore, the pattern to be extracted is linked to a plurality of types of command values. It is possible to switch, and it is possible to make fraud analysis on authentication information even more difficult. Furthermore, since the main control unit can store three or more types of individual identification values in advance, it is not necessary to perform complicated calculations when generating authentication information, and an increase in processing load on the main control unit can be prevented. On the other hand, since the intermediate unit checks and authenticates the communication continuity of the control command information based on the history data, it can detect unauthorized communication switching due to unauthorized control command information. It can contribute to prevention of communication switching. In addition, since the authentication unit extracts the authentication history data using one or more expected values from the authentication information, the authentication history data and the intermediate side are added when the regular individual identification value is not added to the history data. Since the history data does not match, fraud can be reliably detected. In addition, for example, when an illegal board intervenes between the main control unit and the intermediate part, the processing load must be increased because the analysis load on the illegal board increases, so the cost and design difficulty are reduced. By increasing the number, it is possible to contribute to deterring production of illegal substrates. Furthermore, since the intermediate unit performs authentication processing for the main control unit and transmits the intermediate authentication result to the peripheral unit, the peripheral unit only needs to refer to the intermediate authentication result without performing the authentication process. The processing load on the peripheral CPU can be reduced. In addition, since the intermediate unit manages the history of control command information from the main control unit, the history of control command information in the peripheral unit is no longer required, increasing the processing burden on the peripheral unit due to improved security Can be prevented. In addition, since the intermediate unit transmits the control command information from the main control unit to the peripheral unit as it is, the intermediate unit can perform the authentication process and the peripheral unit can perform a predetermined process at the same time. It is possible to prevent a delay from occurring in the predetermined processing. Therefore, it is possible to check the communication continuity of the control command information by using the existing configuration and minimizing the increase in processing load of the main control unit, making it difficult to analyze the authentication information used for authentication, and The processing load on the peripheral CPU can be reduced.

The effect board and the prize ball board correspond to the peripheral board of the present invention.

  The configuration of the board of the pachinko gaming machine 100 is not limited to this. For example, the prize ball control unit 203 is provided on the same printed circuit board as the main control unit 201 or the intermediate unit 202A and the effect control unit 202B. Different configurations can be used. Further, the intermediate unit 202A and the effect control unit 202B are configured to mount one printed circuit board on the other printed circuit board instead of the structure realized by the same printed circuit board, and electrically connect a separate printed circuit board with a cable or the like. It can be set as various embodiments like the structure connected to this.

(Functional configuration of main control board and peripheral board)
First, a functional configuration of the main control board 310 having a function as the main control unit 201 will be described with reference to FIG. The main control board 310 is a functional unit that transmits control command information for operating the peripheral board 330, and includes a data storage unit 311, a history data generation unit 312, a calculation unit 313, an extraction unit 314, an authentication information generation unit 315, The main control side transmission unit 316 is included. The main control board 310 is formed of a board different from the peripheral board 330 and is electrically connected so that unidirectional communication with the intermediate portion 202A of the peripheral board 330 is possible.

  The data storage unit 311 corresponds to the individual identification value storage means of the present invention, and includes control command information (control command), authentication information, individual identification value, history generation method data (control command) transmitted to the peripheral unit 202B via the intermediate unit 202A. Various data such as history generation method) and additional method data are stored. As the data storage unit 311, for example, a part of the ROM 212 and the RAM 213 (see FIG. 2) of the main control unit 201 can be used.

  The data storage unit 311 has a storage area for storing a plurality of types of control command information and a plurality of authentication information transmitted to the intermediate unit 202A in a time series as log data. The number of control command information and authentication information stored in the data storage unit 311 can be arbitrarily set. Further, the timing of storing the control command information and the authentication information in the data storage unit 311 can be arbitrarily determined at the time when the control command information and the authentication information are stored, after being transmitted to the intermediate unit 202A, or the like. In this embodiment, for example, a case where a plurality of types of control command information such as a jackpot reach command, a jackpot start command, a jackpot command, a jackpot end command, and the like are stored in the data storage unit 311 as a history target will be described. Instead, only one kind of predetermined control command information can be stored.

  The data storage unit 311 stores three or more types of individual identification values. Each of the three or more types of individual identification values is a value used by the intermediate portion 202A of the peripheral board 330 for authentication (individual value identification) of the main control board 310 (main control section). Three or more types of individual identification values are different data. As an example of the individual identification value, there are a checksum of each of a plurality of types of predetermined areas in the ROM 212 of the main control unit 210, a predetermined unique value, and the like.

  The history generation method data indicates a history generation method used by the history data generation unit 312 and is determined in advance with the intermediate unit 202A of the peripheral board 330, and an initial value is set at the time of startup or the like to store data. Stored in the unit 311.

  The history data generation unit 312 corresponds to a history data generation unit of the present invention, and generates history data indicating a history of control command information transmitted from the main control board 310 to the intermediate unit 202A of the peripheral board 330, as a predetermined history generation. Generate by method. The history data generation unit 312 is, for example, at a predetermined generation timing such as an arbitrary timing from the generation (confirmation) of control command information in the pachinko gaming machine 100 to the transmission of the control command information to the intermediate unit 202A. Based on the history generation method and the control command information stored in the data storage unit 311, history data is generated and stored. Then, the history data generation unit 312 calculates control command information for a predetermined number of transmissions based on a history generation method such as an error detection method, a predetermined encryption method, an exclusive OR, etc. Is generated. That is, in the history generation method, when generating history data for control command information, for example, the number of retrospective transmissions of transmitted single control command information, the retroactive range of multiple types of control command information, and the like are targets for generation of history data. Specifies control command information. When the history data generation unit 312 generates the history data as a checksum, the total value for a plurality of times of the single type of control command information and the history data become a total value obtained by summing the plurality of control command information. Note that the history data can use, for example, control command information for one time such as the previous time or a predetermined number of times as it is, thereby simplifying processing when generating authentication information, which will be described later.

  The history data generation unit 312 according to the present embodiment will be described with respect to a case where the history data stored in the data storage unit 311 is updated and stored in the generated history data. In this case, the data storage unit 311 functions as history data storage means. Instead of this, for example, the history data may be stored in a register of the CPU 211, a predetermined storage area of the RAM 213, or the like. Also, the history data generating means and the storage means can be realized by dedicated hardware. If the history data generation unit 312 generates the same history data as the individual identification value, for example, the authentication information generation unit 315 does not generate authentication information having the history data, or the main control side transmission The unit 316 discards the authentication information having the history data without transmitting it. Alternatively, various embodiments may be adopted in which the history data generation unit 312 is designed so as to generate history data having a value different from the individual identification value, or corresponds to bit adjustment of history data.

  The computing unit 313 corresponds to the computing means of the present invention, computes different command values and random numbers possessed by each of a plurality of types of control command information by a predetermined computation method, and stores the computation results in the RAM 213 or the like. Remember. Examples of the calculation method include logical operation, four arithmetic operations, and calculation using a predetermined function.

  Here, each of the command values of the plurality of types of control command information is different data. The command value is data defining an individual identification value that can be selected from among three or more types of individual identification values of the main control board 310. In other words, the extraction range (extraction pattern) of individual identification values that can be extracted can be changed depending on the type of command value. Then, each of a plurality of types of command values in this embodiment is mask data that masks other than the desired bits of the random number value, so that the calculation unit 313 simply calculates the command value and the random value, Change the valid bit of the numeric value and specify one computed value within that range. Then, each of a plurality of types of calculation values that are calculation results calculated by the calculation unit 313 is associated with one of three or more types of individual identification values on a one-to-one basis.

  For example, when the operation method is a logical product (AND) operation, the operation unit 313 performs an AND operation on the command value of the control command information that is a fixed value and a random value that changes at random, and calculates the operation value. Ask. This calculated value is a value for randomly specifying one individual identification value among extractable individual identification values predetermined for three or more types of individual identification values. In addition, although the case where the calculating part 313 of a present Example is implement | achieved by software is demonstrated, it replaces with this and you may implement | achieve the same process with hardware, such as a logic time.

  The extraction unit 314 corresponds to the extraction unit of the present invention, and three or more types of individual identification values stored in the data storage unit 311 as one individual identification value corresponding to the calculation result (calculated value) of the calculation unit 313. And is stored in the RAM 213 or the like. That is, the extraction unit 314 extracts one individual identification value corresponding to the calculation value of the calculation unit 313 from the extraction target individual identification values specified by the command value among three or more types of individual identification values. It is the composition which performs.

  In the present embodiment, a configuration in which the calculation unit 313 and the extraction unit 314 are separated will be described. However, instead of this, an embodiment in which the calculation unit 313 and the extraction unit 314 are configured integrally may be employed. it can.

  The authentication information generation unit 315 corresponds to authentication information generation means of the present invention, and generates authentication information used by the intermediate unit 202A for authentication of the main control unit 201. The authentication information generation unit 315 generates authentication information by adding the individual identification value extracted by the extraction unit 314 to the latest history data stored in the data storage unit 311 using a predetermined addition method. That is, the authentication information generated by the authentication information generation unit 315 includes authentication data that is a combined value obtained by adding history data and an individual identification value. The addition method is a method for the main control board 310 to add the individual identification value to the history data, and is determined in advance with the intermediate portion 202A of the peripheral board 330. The additional method is, for example, one predetermined calculation method among a plurality of types of calculation methods such as four arithmetic operations, XOR, XNOR, and the like, and the intermediate portion 202A of the main control board 310 and the peripheral board 330 is Additional method data indicating the calculation method is stored in the data storage unit 311 or the like. Further, in the present embodiment, a case where an individual identification value is added to the latest history data will be described, but instead of this, for example, when a plurality of history data is stored in time series, a history a predetermined number of times before Various embodiments such as addition to data can be made.

  The main control side transmission unit 316 corresponds to the main control side transmission unit of the present invention, and transmits each of the authentication information and the control command information generated by the authentication information generation unit 315 to the intermediate unit 202A of the peripheral board 330. Then, the main control side transmission unit 316 of the present embodiment transmits control command information from the main control board 310 to the intermediate unit 202A of the peripheral board 330 as a control signal. For example, the main control side transmission unit 316 transmits the authentication information to the intermediate unit 202A as an authentication information signal that is a signal different from the control signal transmitted from the main control board 310 to the intermediate unit 202A. Thereby, in pachinko gaming machine 100, the control signal and the authentication information signal are differentiated.

  Next, a functional configuration of the peripheral board 330 having a function as a peripheral part such as the above-described effect control unit 202B will be described. As shown in FIG. 3, the peripheral board 330 includes an intermediate part 202A and a peripheral part (effect control part) 202B. The peripheral board 330 is configured such that the intermediate portion 202A and the peripheral portion 202B can communicate with each other. In the present embodiment, the peripheral board 330 having the intermediate section 202A and the effect control section 202B will be described. Alternatively, a peripheral board having the intermediate section 202A and the prize ball control section 203 may be used. it can.

  Next, the intermediate unit 202A includes an intermediate side reception unit 331, an intermediate side storage unit 332, an intermediate side history data generation unit 333, a specification unit 334, an authentication history data extraction unit 335, an intermediate authentication result data generation unit 336, an intermediate side A transmission unit 337 is included.

  The intermediate receiving unit 331 corresponds to the intermediate receiving unit of the present invention, and receives authentication information, control command information (control command), and the like transmitted by the main control board 310. The intermediate receiving unit 331 of the present embodiment receives the authentication information from the main control board 310 by receiving an authentication information signal corresponding to the authentication information, for example. When receiving the control signal from the main control unit 201 separately from the authentication information signal, the intermediate receiving unit 331 stores the control command information indicated by the received control signal in the intermediate storage unit 332 in time series. Then, the control signal is transmitted as it is from the intermediate transmission unit 337 described later to the peripheral unit 202B. That is, the intermediate receiving unit 331 has a function of transferring a control signal (control command information) from the main control board 310 to the peripheral unit 202B.

  The intermediate storage unit 332 corresponds to the expected value storage unit of the present invention. As the intermediate storage unit 332, for example, a part of the ROM 232 and the RAM 233 (see FIG. 2) of the effect control unit 202 can be used. The intermediate storage unit 332 also has a storage area for storing a plurality of control command information and a plurality of authentication information received from the main control board 310 as log data in a time series manner, like the main control board 310. ing.

  The intermediate storage unit 332 has three or more types of individual identification values to be received from the main control board 310, that is, each of three or more types of individual identification values stored in the data storage unit 311 of the main control board 310. 3 or more types of expected values that match As a result, the intermediate part 202A of the peripheral board 330 matches any one of three or more expected values if the individual identification value added to the history data of the authentication information is a normal individual identification value. The intermediate unit 202A can extract history data from the authentication information. Further, if the individual identification value of the authentication information is invalid, it does not match any of the three or more types of expected values, so that the normal part 202A cannot extract the normal history data from the authentication information.

  The intermediate storage unit 332 stores the same history generation method data and additional method data as the main control unit 201. The history generation method data indicates a history generation method used by the intermediate history data generation unit 333, and an initial value is set at the time of startup or the like and is stored in the intermediate storage unit 332. The additional method data indicates the same additional method as that of the main control board 310 used by the authentication history data extraction unit 335.

  The intermediate-side history data generation unit 333 corresponds to the intermediate-side history data generation means of the present invention, and the intermediate-side history data indicating the history of control command information received from the main control board 310 is the same as that of the main control board 310. Generate by history generation method. The intermediate history data generation unit 333 receives the same history generation method and intermediate side as the main control board 310 at a predetermined intermediate generation timing such as when receiving control command information from the main control board 310, after receiving the control command information. Based on the control command information stored in the storage unit 332, intermediate side history data is generated and stored. That is, the intermediate history data generation unit 333 calculates control command information for a predetermined number of receptions based on a history generation method such as an error detection method, a predetermined encryption method, an exclusive OR, etc. Generate data. Therefore, the intermediate history data matches the history data of the main control board 310 if only the control command information transmitted by the main control board 310 is received. It can be determined that information is received.

  The intermediate history data generation unit 333 according to the present embodiment will be described with respect to a case where the intermediate history data stored in the intermediate storage unit 332 is updated to the generated intermediate history data and stored. In this case, the intermediate storage unit 332 functions as an intermediate history data storage unit. Instead of this, for example, the intermediate history data may be stored in a register of the CPU 231, a predetermined storage area of the RAM 233, or the like. Further, the intermediate history data generating means and the storage means can be realized by dedicated hardware.

  The specifying unit 334 corresponds to the specifying unit of the present invention, and the main control board 310 has three or more types of individual identification values based on the command value of the control command information received from the main control board 310 by the intermediate receiving unit 331. The individual identification value to be extracted is specified from the inside. For example, when the main control board 310 has the command value of the control command information as two extraction targets, the two expected values corresponding to the two individual identification values are stored in the intermediate storage unit 332. The expected value corresponding to the extraction target is specified from the three or more types of expected values.

  The authentication history data extraction unit 335 corresponds to the authentication history data extraction unit of the present invention, and is based on the expected value specified by the specifying unit 334 and the same additional method as the main control board 310. One or a plurality of authentication history data is extracted from the authentication information received from. Specifically, the authentication history data extraction unit 335 removes one or more expected values from the authentication information by the addition method, extracts one or more authentication history data, and stores them in the intermediate storage unit 332. That is, the authentication history data extraction unit 335 extracts two authentication history data when two expected values are specified, and three when three expected values are specified. The history data for authentication is extracted. Accordingly, one or a plurality of authentication history data is a value obtained by removing each of one or a plurality of expected values from the authentication information (authentication data), and therefore extracted from the authentication information if received. One of the one or more authentication history data is the history data of the main control board 310. In addition, by extracting and using the expected value corresponding to the command value to extract the authentication history data from the authentication information, the authentication accuracy can be improved rather than extracting the authentication history data using all the expected values. It can be improved.

  The intermediate authentication result data generation unit 336 corresponds to the intermediate authentication result data generation unit of the present invention, and is stored in the intermediate storage unit 332 in one or a plurality of authentication history data extracted by the authentication history data extraction unit 335. Based on the determination result as to whether or not there is a match with the latest stored intermediate side history data, the main control board (main control unit) 310 is authenticated, and intermediate authentication result data indicating the authentication result Is transmitted to the peripheral section 202B. Then, if there is a match with the intermediate history data, the intermediate authentication result data generation unit 336 determines that the received authentication information history data is valid, and thus establishes authentication. In addition, when there is no data that matches the intermediate history data, the intermediate authentication result data generation unit 336 uses, for example, incorrect authentication information in which the history data and the intermediate history data are different due to fraud. Therefore, it is possible to determine that the history data or individual identification value of the received authentication information is invalid, and authentication is not established. That is, the intermediate authentication result data indicates an authentication result indicating whether or not the intermediate unit 202A has authenticated the main control board 310 (main control unit 201) based on communication continuity (history data).

  In this embodiment, after the authentication history data extraction unit 335 extracts a plurality of authentication history data, the intermediate authentication result data generation unit 336 compares each of the plurality of authentication history data with the intermediate side history data. However, instead of this, for example, every time the authentication history data extraction unit 335 extracts one authentication history data, the intermediate authentication result data generation unit 336 compares with the intermediate history data. It can also be.

  The intermediate side transmission unit 337 corresponds to the intermediate side transmission unit of the present invention, and transmits the intermediate authentication result data generated by the intermediate authentication result data generation unit 336 to the peripheral unit 202B. Then, the intermediate-side transmitting unit 337 transmits the intermediate authentication result data generated by the intermediate authentication result data generating unit 336 to the peripheral unit 202B as an intermediate authentication result signal. Further, the intermediate transmission unit 337 transmits the control signal received from the main control board 310 to the peripheral unit 202B as it is. That is, the main control unit 201 transmits a control signal (control command information) to the intermediate unit 202A, thereby transmitting it to the peripheral unit 202B via the intermediate unit 202A.

  Next, the peripheral unit 202B includes a peripheral side receiving unit 351 and a processing unit 352.

  The peripheral side receiving unit 351 corresponds to the peripheral side receiving unit of the present invention, and receives control command information, intermediate authentication result data, and the like transmitted by the intermediate unit 202A of the peripheral board 330. The peripheral side reception unit 351 of the present embodiment receives the intermediate authentication result data from the intermediate unit 202A, for example, by receiving an intermediate authentication result signal to which the intermediate authentication result data is added. Then, the peripheral side receiving unit 351 receives control command information from the main control board 310 by receiving a control signal from the intermediate unit 202A.

  The processing unit 352 corresponds to the processing means of the present invention, and performs predetermined processing in the pachinko gaming machine 100 corresponding to the control command information received from the main control board 310 according to the intermediate authentication result data received from the intermediate unit 202A. Do. When the intermediate authentication result data indicates that authentication has been established, the processing unit 352 performs the predetermined processing corresponding to the control command information indicated by the control signal received from the intermediate unit 202A, and indicates that authentication has not been established. If this is the case, an announcement is made. The predetermined process is a process corresponding to the control command information from the main control unit 201 in the pachinko gaming machine 100. For example, an outage process, a jackpot reach process, a jackpot start process, a jackpot round process, a jackpot end process, And the like.

  In the present embodiment, a description will be given of a configuration in which data communicated between the intermediate unit 202A and the peripheral unit 202B is transmitted without encryption. However, as described in the main control board 310 and the intermediate unit 202A described above. In addition, data may be encrypted and transmitted between the intermediate unit 202A and the peripheral unit 202B.

  In this embodiment, the CPU 211 of the main control board 310 functions as the first computer, the CPU 231 of the intermediate section 202A of the peripheral board 330 functions as the second computer, and the CPU 241 of the effect control section 202B of the peripheral board 330 functions as the third computer. Will be described. The ROM 212 of the main control board 310 causes the first computer to function as various means such as history data generation means, calculation means, extraction means, authentication information generation means, main control side transmission means, etc. The main control side authentication program is stored. The ROM 232 of the intermediate portion 202A of the peripheral board 330 includes the intermediate computer receiving means, intermediate history data generating means, specifying means, authentication history data extracting means, and intermediate authentication result data generating means. And an intermediate side authentication program for functioning as various means such as intermediate side transmission means.

That is, the authentication program of the present invention is constituted by the main control side authentication program, the intermediate side authentication program, and the peripheral side authentication program.

(Basic operation of pachinko machines)
An example of the basic operation of the pachinko gaming machine 100 configured as described above will be described. The main control unit 201 outputs the winning situation of the game balls for each winning opening to the winning ball control unit 203 as control command information. The winning ball control unit 203 pays out the number of winning balls corresponding to the winning situation in accordance with the control command information output from the main control unit 201.

  The main control unit 201 outputs corresponding control command information to the effect control unit 202B every time a game ball wins the start winning opening 105, and the effect control unit 202B displays the symbols of the symbol display unit 104 in a variable manner. Repeat and stop. The main control unit 201 outputs the corresponding control command information to the effect control unit 202B when the occurrence of the jackpot is determined, and the effect control unit 202B aligns the predetermined symbols and stops the variable display. Then, control for opening the special winning opening 109 is performed. The effect control unit 202B performs various effect displays on the symbol display unit 104 in addition to the symbol variation display during the jackpot occurrence period and during the reach until the jackpot occurrence or at the time of the reach notice. . In addition, effects such as performing specific driving for various types of accessories and correcting the display state of the lamp 261 are performed.

  Then, the main control unit 201 opens the big prize opening 109 a plurality of times during the jackpot occurrence period. For example, 15 rounds are repeatedly executed as one open is one round. The period of one round is a period until 10 game balls are won in the big winning opening 109, for example, or a predetermined period (for example, 30 seconds). At this time, the winning ball control unit 203 pays out with, for example, 15 winning balls per winning game ball to the big winning opening 109. The pachinko gaming machine 100 releases the jackpot state after the jackpot ends and returns to the normal gaming state.

(Details of processing by each control unit)
Next, details of various processes performed by each control unit will be described. First, control processing of the effect control unit 202B by the main control unit 201 will be described. 4 to 9, the authentication data and the accompanying data are not considered in order to clarify the control processing procedure of the effect control unit 202B. That is, in the description of FIGS. 4 to 9, “send a command” means “send a control signal including data (control command information) indicating the command”. The presence or absence of data is not considered.

  The main control unit 201 determines in step S401 shown in FIG. 4 whether or not the pachinko gaming machine 100 is powered on. When the main control unit 201 determines that the power is not turned on (S401: No), the main control unit 201 waits until the pachinko gaming machine 100 is turned on by repeating this determination process. On the other hand, when the main control unit 201 determines that the power is turned on (S401: Yes), the main control unit 201 proceeds to the process of step S402.

  In step S402, the main control unit 201 transmits a power-on command to each peripheral unit such as the effect control unit 202B and the prize ball control unit 203, and the process proceeds to step S403. When the power-on command is transmitted by this process, the effect control unit 202B controls the lamp control unit 251, the sound control unit 252, and the symbol display unit 104 for control command information (specifically, for power-on effect). Control command information for instructing lamp lighting, sound output, demonstration (demo) screen display, and the like.

  In step S <b> 403, the main control unit 201 refers to the unlottery winning number data stored in the ROM 212 or the RAM 213, and determines whether or not the unlotted winning number is zero. The number of undrawn winnings is the number obtained by subtracting the number of times that a lottery corresponding to the winning ball has been performed (number of already drawn lots) from the number of winning balls detected at the start winning opening 105 (number of winnings). If the main control unit 201 determines that the number of undrawn winning prizes is not zero (S403: No), the process proceeds to step S410. On the other hand, if the main control unit 201 determines that the number of undrawn winning prizes is zero (S403: Yes), in step S404, the main control unit 201 measures the time elapsed since the demonstration was started, and proceeds to the process of step S405. To do.

  The main control unit 201 determines whether or not a predetermined time has elapsed since the demonstration was started. If the main control unit 201 determines that the predetermined time has not elapsed since the demonstration was started (S405: No), the main control unit 201 proceeds to the process of step S407. On the other hand, if the main control unit 201 determines that a predetermined time has elapsed since the demonstration was started (S405: Yes), in step S406, the main control unit 201 transmits a customer waiting demonstration command to the effect control unit 202B, and the process of step S407 Migrate to

  In step S407, the main control unit 201 determines whether or not a winning ball has been detected by the start winning port detection unit 221. If the main control unit 201 determines that no winning ball has been detected (S407: No), the main control unit 201 returns to the process of step S404 and repeats a series of processes. On the other hand, when determining that a winning ball has been detected (S407: Yes), the main control unit 201 clears the time measured since the demonstration was started in step S408, and in step S409, the number of undrawn winning prizes 1 is added to and the process proceeds to step S410. In step S410, the main control unit 201 obtains a jackpot determination random number. In step S411, the main control unit 201 subtracts 1 from the number of undrawn winning prizes, and proceeds to the process of step S412 shown in FIG.

  In step S412, the main control unit 201 determines whether or not the jackpot determination random number is a jackpot random number. If the main control unit 201 determines that it is a jackpot random number (S412: Yes), in step S413, the main control unit 201 transmits a jackpot reach command (symbol variation command) to the effect control unit 202B. In step S414, the main control unit 201 determines whether the symbol variation time has elapsed. When determining that the symbol variation time has not elapsed (S414: No), the main control unit 201 repeats this determination process to wait for the symbol variation time to elapse. On the other hand, when the main control unit 201 determines that the symbol variation time has elapsed (S414: Yes), in step S415, the main control unit 201 transmits a symbol stop command to the effect control unit 202B, and proceeds to the process of step S416.

  In step S416, the main control unit 201 transmits a jackpot start command to the effect control unit 202B. Subsequently, in step S417, the main control unit 201 sequentially transmits commands corresponding to each of the rounds in the jackpot to the effect control unit 202B. To do. Then, when transmission of the jackpot command for all the rounds is completed, the main control unit 201 transmits a jackpot end command to the effect control unit 202B in step S418, and the process proceeds to step S422.

  If the main control unit 201 determines in step S412 that the random number is not a big hit random number (S412: No), in step S419, the main control unit 201 transmits a loss reach command (symbol variation command) to the effect control unit 202B. Transition to processing. In step S420, the main control unit 201 determines whether the symbol variation time has elapsed. When determining that the symbol variation time has not elapsed (S420: No), the main control unit 201 repeats this determination process to wait for the symbol variation time to elapse. On the other hand, if the main control unit 201 determines that the symbol variation time has elapsed (S420: Yes), in step S421, the main control unit 201 transmits a symbol stop command to the effect control unit 202B, and proceeds to the process of step S422.

  In step S422, the main control unit 201 determines whether or not the pachinko gaming machine 100 is powered off. When determining that the power is not turned off (S422: No), the main control unit 201 returns to the process of step S403 shown in FIG. 4 and repeats a series of processes. On the other hand, if the main control unit 201 determines that the power is turned off (S422: Yes), in step S423, the main control unit 201 transmits an end process command to the effect control unit 202B, and ends the process according to this flowchart.

  The various commands in FIGS. 4 and 5 described above correspond to the control command information of the present invention, and each time the main control board 310 transmits the various control command information, the control command information is stored in the data storage unit 311 as a history. I remember it. In response to the storage of the control command information, the main control board 310 updates the history data in the data storage unit 311. Note that the history data is updated when a plurality of types of authentication information is generated, so that the processing load on the main control board 310 can be reduced. The intermediate unit 202A of the peripheral board 330 stores the control command information as a history in the intermediate storage unit 332 each time various control command information is received, and the intermediate side history data of the intermediate storage unit 332 is stored. Update.

  Next, with reference to the drawing of FIG. 6, an example of the transmission timing of the jackpot related commands (jackpot reach command, jackpot start command, jackpot command, jackpot end command) from the main control unit 201 to the effect control unit 202B in the pachinko gaming machine 100 To explain.

  The jackpot reach command is sent more frequently and randomly than the actual jackpot occurs. The jackpot start command is transmitted only once when shifting to the jackpot state when a jackpot is actually generated. The jackpot command is continuously transmitted for each round after shifting to the jackpot state. The jackpot end command is transmitted only once when all rounds of the jackpot state are completed and the normal state is entered.

  In the following, a process for a jackpot reach command (when a jackpot reach command (see step S413 in FIG. 5) or a loss reach command (see step S419 in FIG. 5) is received) and a jackpot reach process will be described.

  First, the symbol variation process by the effect control unit (peripheral unit) 202B will be described with reference to the flowchart shown in FIG. The effect control unit 202B determines whether or not a symbol variation command is received from the main control unit 201 in step S701 shown in FIG. When it is determined that the symbol variation command has not been received (S701: No), the effect control unit 202B repeats this determination process to wait for reception of the symbol variation command. On the other hand, if it is determined that the symbol change command has been received (S701: Yes), the effect control unit 202B acquires a random effect selection random number in step S702, and in step S703, the variable effect is selected based on the acquired random number. The type is selected, and the process proceeds to step S704. In step S704, the effect control unit 202B transmits an effect start command for each variable effect to the lamp control unit 251 and the audio control unit 252, and the process proceeds to step S705.

  In step S705, the effect control unit 202B determines whether the effect time has elapsed. When the effect control unit 202B determines that the effect time has elapsed (S705: Yes), the effect control unit 202B proceeds to the process of step S707. On the other hand, when it is determined that the effect time has not elapsed (S705: No), the effect control unit 202B determines whether or not a symbol stop command has been received from the main control unit 201 in step S706. And when it determines with the effect control part 202B not receiving the symbol stop command (S706: No), it returns to the process of step S705 and repeats a series of processes. On the other hand, when determining that the symbol stop command has been received (S706: Yes), the effect control unit 202B transmits the effect stop command to the lamp control unit 251 and the voice control unit 252 in step S707, and according to this flowchart. The process ends.

  Next, the big hitting process by the effect control unit 202B will be described with reference to the flowchart shown in FIG. The effect control unit 202B determines whether or not a jackpot start command (see step S416 in FIG. 5) is received from the main control unit 201 in step S801 shown in FIG. When it is determined that the jackpot start command has not been received (S801: No), the effect control unit 202B waits for reception of the jackpot start command by repeating this determination process. On the other hand, if it is determined that the jackpot start command has been received (S801: Yes), the effect control unit 202B transmits a jackpot start processing command to the lamp control unit 251 and the voice control unit 252 in step S802, and step S803. Move on to processing.

  In step S803, the effect control unit 202B determines whether or not a round-by-round jackpot command (see step S417 in FIG. 5) has been received from the main control unit 201. When it is determined that the jackpot command has not been received (S803: No), the effect control unit 202B repeats this determination process to wait for the jackpot command to be received. On the other hand, when it is determined that the jackpot command has been received (S803: Yes), the effect control unit 202B has a round corresponding to the round jackpot command received by the lamp control unit 251 or the voice control unit 252 in step S804. Another processing command is transmitted, and the process proceeds to step S805.

  In step S805, the effect control unit 202B determines whether or not a jackpot end command (see step S418 in FIG. 5) has been received from the main control unit 201. When it is determined that the jackpot end command has not been received (S805: No), the effect control unit 202B waits for the reception of the jackpot end command by repeating this determination process. On the other hand, if it is determined that the jackpot end command has been received (S805: Yes), the effect control unit 202B transmits a jackpot end processing command to the lamp control unit 251 and the voice control unit 252 in step S806, and this flowchart. The process by is terminated.

  Next, lamp control processing by the lamp control unit 251 will be described with reference to a flowchart shown in FIG. Here, a process when an effect start command is received from the effect control unit 202B (during symbol variation) will be described. Then, the lamp control unit 251 determines whether or not an effect start command is received from the effect control unit 202B in step S901 illustrated in FIG. When it is determined that the effect start command has not been received (S901: No), the lamp control unit 251 waits for the reception of the effect start command by repeating this determination process. On the other hand, if the lamp control unit 251 determines that an effect start command has been received (S901: Yes), in step S902, the command-specific data prepared in advance for each command is read, and the process proceeds to step S903.

  In step S903, the lamp control unit 251 executes a selection routine for each command, sets lamp data corresponding to the received effect start command in step S904, and outputs lamp data to the lamp 261 in step S905. Then, the process proceeds to step S906. In this process, the lamp 261 is turned on or off based on the lamp data.

  In step S906, the lamp control unit 251 determines whether or not an effect stop command has been received from the effect control unit 202B. When it is determined that the effect stop command has not been received (S906: No), the lamp control unit 251 waits for the reception of the effect stop command by repeating this determination process. On the other hand, if the lamp control unit 251 determines that an effect stop command has been received (S906: Yes), in step S907, the lamp control unit 251 stops the output of the lamp data and ends the process according to this flowchart.

  Note that although the processing of the lamp control unit 251 is shown in FIG. 9, the sound control by the sound control unit 252 is almost the same as the processing of FIG. The voice control process by the voice control unit 252 may be performed by replacing “lamp data” in steps S904, S905, and S907 with “voice data” in the process of FIG.

(Control signal data format)
Next, an example of a normal control signal output from the main control unit 201 will be described.

  In FIG. 10, control command information 1010 indicated by a normal control signal has a command value 1001 and accompanying data 1002. The command value 1001 is the command value described above, and is data unique to each command such as a reach command, a jackpot start command, a round command, and the like. The accompanying data 1002 is data accompanying the command value 1001, and is data necessary for processing based on the command value 1001 such as the number of winning game balls, for example.

(Authentication information data format)
Next, an example where an authentication information signal different from the control signal described above has authentication information will be described. In the present embodiment, description will be made on the assumption that the main control unit 201 outputs an authentication information signal to the intermediate unit 202A, thereby transmitting each of a plurality of types of authentication information from the main control unit 201 to the intermediate unit 202A. .

  In FIG. 11, authentication information 1020 includes an identification unit 1021 and a data unit 1022. The identification unit 1021 is set with identification data that can identify the authentication information 1020. An example of the identification data is one type of authentication command. For example, hexadecimal values such as 0xA0 and 0xB0 are set. Accordingly, the intermediate unit 202A can identify the authentication information 1020 based on the identification unit 1021. The authentication command can be differentiated from the command value 1001 by using a command different from the control command having the command value 1001 described above.

  In the data part 1022, authentication data obtained by adding an individual identification value to the above-described history data is set. In this embodiment, the case where the authentication information 1020 includes the identification unit 1021 and the data unit 1022 will be described, but instead, the identification unit 1021 is excluded and the authentication information 1020 is configured only by the data unit 1022. You can also.

  Subsequently, the intermediate authentication result signal shown in FIG. 11 transmits intermediate authentication result information 1030 indicating the authentication result obtained by authenticating the main control unit 201 using the authentication information 1020 described above to the peripheral unit 202B. . The intermediate authentication result information 1030 includes an identification unit 1031 and a result unit 1032. The identification unit 1031 is set with authentication result identification data capable of identifying the intermediate authentication result information 1030. As the authentication result identification data, various embodiments such as using data set in the identification unit 1021 of the authentication information 1020 and using predetermined data can be used. The result unit 1032 is set with authentication result data indicating whether or not the intermediate unit 202A has authenticated the main control board 310. Note that when the result unit 1032 indicates that authentication is not established, the result unit 1032 includes detailed data indicating that the authentication data is not established due to a mismatch in history data, for example.

(Example of command value setting for control command information)
The command value 1001 of the control command information 1010 is a unique value that can identify the control command information 1010. The command value 1001 defines different numbers of individual identification values to be extracted, which are determined in advance for three or more individual identification values, by calculating a logical product with a random number value. This is a value for specifying one individual identification value. The command value 1001 is set, for example, between the time when the pachinko gaming machine 100 is designed and the time when it is manufactured. The command value 1001 of this embodiment is mask data for extracting (validating) a desired bit of the random value by the logical product operation. For example, when extracting the lower 1 bit of the random value, the command value is 0x01, and when extracting the lower 2 bits of the random value, the command value is 0x03.

  Thereby, when the logical product of the command value 1001 and the random number value is calculated, a calculated value corresponding to a desired bit of the random value defined by the command value 1001 can be obtained. Therefore, each of the plurality of types of command values 1001 is set as different mask data from which arbitrary bits that always change the random number value can be extracted.

  In addition, although the random number value of an Example demonstrates the case where the main control board 310 produces | generates a random number value when the main control board 310 calculates with the command value 1001 of the control command information 1010, it replaces with this, for example, The jackpot determination random number used in the pachinko gaming machine 100, other random numbers, or the like may be used.

(Example of relationship between calculated value and individual identification value)
First, four individual identification values UA, UB, UC, and UD are determined as three or more types of individual identification values. Then, as shown in FIG. 12, the individual identification value UA is set to 0x11, the individual identification value UB is set to 0x33, the individual identification value UC is set to 0x55, and the individual identification value UD is set to 0x77, which are relative addresses of the data storage unit 311 and the like. Assigned to each of addresses 0x00, 0x01, 0x02, and 0x03. In this embodiment, the relative address is a calculated value obtained by calculating the logical product of the command value and the random number value, and one individual identification value can be derived from the calculated value. Note that calculation values after 0x04 are repeated from relative addresses 0x00 to 0x03.

(Operation example of command value and random value)
Next, an example of calculating the logical product of the command value and the random value will be described. It is assumed that the command value and the random number value are 8 bits, and the control command information 1010 is four types of control commands CA, CB, CC, and CD.

  First, as shown in FIG. 13, the command value of the control command CA is 0x00, the command value of the control command CB is 0x01, the command value of the control command CC is 0x02, and the command value of the control command CD is 0x03.

  When the logical product of the command value (0x00) of the control command CA and the random value is calculated, the value of the random value becomes invalid, and the calculated value is only one (fixed) 0x00. Therefore, in the case of the calculated value of the control command CA and the random number value, the relative address that can be selected from the above-mentioned relative addresses 0x00 to 0x03 is 0x00, and therefore, among the four individual identification values UA, UB, UC, and UD. From this, only one individual identification value UA is an individual identification value that can be extracted.

  When the logical product of the command value (0x01) of the control command CB and the random value is calculated, only the lower bit is valid for the random value, and the calculated value is either 0x00 or 0x01 depending on the random value that changes randomly. One can be specified. Therefore, in the case of the calculated value of the control command CB and the random number value, the relative address that can be selected from the above-described relative addresses 0x00 to 0x03 is 0x00 or 0x01, so that the four individual identification values UA, UB, UC, UD The two individual identification values UA and UB corresponding (stored) to the relative address are extracted from the individual identification values.

  When the logical product of the command value (0x02) of the control command CC and the random value is calculated, only the lower 2nd bit of the random value is valid, and the calculated value is either 0x00 or 0x02 depending on the random value that changes randomly. One can be specified. Therefore, in the case of the calculated value of the control command CC and the random number value, the relative address that can be selected from the above-described relative addresses 0x00 to 0x03 is 0x00 or 0x02, and thus the four individual identification values UA, UB, UC, UD The two individual identification values UA and UC corresponding (stored) to the relative address are extracted from the individual identification values. The control command CC is different in that the number of individual identification values that can be extracted matches the control command CB, but the individual identification value UB that can be extracted from the control command CB cannot be extracted.

  When the logical product of the command value (0x03) of the control command CD and the random value is calculated, all the lower 2 bits of the random value are valid, and the calculated value is any one of 0x00 to 0x03 depending on the random value that changes randomly. Can be specified. Therefore, in the case of the calculated value of the control command CD and the random value, the relative address that can be selected from the above-described relative addresses 0x00 to 0x03 is any one of 0x00 to 0x03, and therefore, the four individual identification values UA and UB , UC and UD are all extractable individual identification values. That is, the control command CD differs from the control commands CA, CB, and CC in the number of individual identification values that can be extracted.

  As described above, by calculating the command value and random number value of the control commands CA, CB, CC, CD, one of the four individual identification values UA, UB, UC, UD, or two individual identification values The number of objects to be extracted can be changed in association with the desired control command information 1010, and the individual identification value can be extracted at random from the random number value.

  In the present embodiment, a case where four control commands UA, UB, UC, and UD are used will be described. However, instead of this, five or more control command information 1010 may be used. In that case, it can be set as various different embodiments, such as increasing the number of individual identification values and associating a plurality of control commands with one individual identification value.

  In the present invention, the control commands CA, CB, CC, and CD having the command values described above are selected from a plurality of existing control commands, for example, at the time of designing or manufacturing the pachinko gaming machine 100. By using them, it is possible to prevent the above-described new addition of command values.

  As shown in FIG. 14, when the command value of the existing control command CA is 0xX0, the command value of the control command CB is 0xX1, the command value of the control command CC is 0xX2, and the command value of the control command CD is 0xX3, In the embodiment, when the four individual identifications UA, UB, UC, and UD are accessed, an address generation process for adjusting the address range is performed. Note that “X” in the command value means that any of hexadecimal numbers 0 to F may be used. Further, the control command information 1010, the effective bit of the random value, the extractable range, and the selectable address in FIG. 14 are the same as those described with reference to FIG.

  In that case, as an example of the address generation process, the lower 4 bits are extracted by a bit mask or the like from the operation value by the logical product of the command value and the random number value, so that the value matching the above-described relative address is obtained. Generate. Alternatively, the address generation processing may be an embodiment in which the relative address is generated using a calculation value of a command value and a random value, a conversion table, and the like.

(Example of additional method)
Next, as the above-described method of adding history data to the individual identification value, for example, one arithmetic method among four arithmetic operations, XOR, XNOR and the like is determined in advance in the pachinko gaming machine 100. When the additional method is determined as “+” of the four arithmetic operations, the main control board 310 sets authentication data obtained by adding the individual identification value extracted as described above to the history data in the data portion 1022 and authentication information. 1020 is generated. On the other hand, the intermediate part 202A of the peripheral board 330 subtracts one or more expected values specified as described above from the data set in the data part 1022 of the received authentication information 1020, thereby obtaining one or more authentication histories. Extract data. Since the three or more types of expected values coincide with each of the three or more types of individual identification values, one or a plurality of authentication history data extracted by removing the expected value by the intermediate portion 202A of the peripheral board 330. Since one piece of regular history data has been extracted, it should be consistent with the intermediate history data.

  In addition, when the additional method is determined as “−” of the four arithmetic operations, the main control board 310 sets authentication data obtained by subtracting the individual identification value extracted as described above from the history data in the data portion 1022 and authentication information. 1020 is generated. On the other hand, the intermediate section 202A of the peripheral board 330 adds one or more expected values specified as described above from the data set in the data section 1022 of the received authentication information 1020, thereby adding one or more authentication histories. Extract data. Even if it implements in this way, since three or more types of expected values coincide with three or more types of individual identification values, if the intermediate portion 202A of the peripheral board 330 adds the expected values, the extracted 1 or Since one regular history data can be extracted from a plurality of authentication data, it should match the intermediate history data.

  Therefore, any calculation method may be used as long as the additional method is a calculation method in which the intermediate portion 202A of the peripheral board 330 can perform reverse calculation. In the present embodiment, the case where the main control board 310 adds only the individual identification value to the history data will be described. Instead, it is determined in advance between the individual identification value and the intermediate portion 202A of the peripheral board 330. Various embodiments such as adding both of the added data (for example, a predetermined value) can be used.

(Processing for sending and receiving authentication information signals)
Hereinafter, a communication example of the authentication information signal performed between the main control unit 201 and the intermediate unit 202A will be described. First, an example of an authentication information signal transmission procedure by the CPU 211 (first computer) of the main control unit 201 will be described with reference to a flowchart of FIG. It is assumed that the three or more types of individual identification values are the above-described four individual identification values UA, UB, UC, and UD.

  When the power of the pachinko gaming machine 100 is turned on (turned on), the main control unit 201 executes the authenticated side processing shown in FIG. 15, and the control command information 1010 stored in the data storage unit 311 is stored in step S1201. Based on this, it is determined whether or not control command information is generated. If the main control unit 201 determines that the control command information 1010 has not been generated (S1201: No), the main control unit 201 proceeds to the process of step S1209. On the other hand, when the main control unit 201 determines that the control command information 1010 has been generated (S1201: Yes), in step S1202, the history generation method data in the data storage unit 311 and the history generation method are the generation targets. Based on the control command information 1010, history data is generated and stored in the data storage unit 311. Thereafter, the process proceeds to step S1203.

  In step S1203, the main control unit 201 obtains a random number value, performs a calculation based on the logical product of the command value 1001 of the control command information 1010 and the random number value, stores the calculation result in the RAM 213, and then stores the calculation result in step S1204. Proceed to processing. In step S1204, the main control unit 201 extracts one individual identification value corresponding to the calculation result (relative address) from the four individual identification values UA, UB, UC, and UD, and stores them in the RAM 213 or the like. Then, the process proceeds to step S1205.

  In step S1205, the main control unit 201 generates authentication data (composite value) in which the extracted individual identification value is added to the latest history data stored in the data storage unit 311 by the addition method. The process proceeds to S1206. In step S1206, the main control unit 201 generates authentication information 1020 in which the authentication command is set in the identification unit 1021 and the authentication data is set in the data unit 1022, and is stored in the data storage unit 311. Then, the process proceeds to step S1207. Note that the timing for generating the authentication information 1020 of the main control unit 201 can be set to a predetermined authentication timing or the like when the individual identification value is generated.

  In step S1207, the main control unit 201 encrypts the authentication information 1020 generated this time with a predetermined encryption method with the intermediate unit 202A, and in step S1208, at the predetermined transmission timing, An authentication information signal is generated based on the encrypted authentication information 1020 and transmitted from the main control side transmission unit 316 to the intermediate unit 202A, and then the process proceeds to step S1209. If encryption is not required between the main control unit 201 and the intermediate unit 202A, the processing in step S1207 is deleted, and the authentication information 1020 is transmitted to the intermediate unit 202A as it is.

  In step S1209, the main control unit 201 determines whether or not the pachinko gaming machine 100 is powered off. If the main control unit 201 determines that the power is not turned off (S1209: No), the main control unit 201 returns to the process of step S1201 and repeats a series of processes. On the other hand, when the main control unit 201 determines that the power is turned off (S1209: Yes), the process according to this flowchart ends.

  Next, the procedure of the authentication information signal reception process by the CPU 231 (second computer) of the intermediate unit 202A will be described with reference to the flowchart of FIG.

  When the intermediate unit 202A executes the authentication-side process shown in FIG. 16, the intermediate-side receiving unit 331 controls the main-side control unit 201 based on the control command information 1010 stored in the intermediate-side storage unit 332 in step S1301. It is determined whether command information 1010 has been received. If it is determined that the control command information 1010 has not been received (S1301: No), the intermediate unit 202A proceeds to the process of step S1304.

  On the other hand, if the intermediate unit 202A determines that the control command information 1010 has been received (S1301: Yes), the history generation method data in the intermediate storage unit 332 and the intermediate storage unit 332 in step S1302, as in the case of the main control unit 201. Based on the control command information 1010 to be generated by the history generation method, intermediate history data is generated and stored in the intermediate storage unit 332, and then the process proceeds to step S1303. In step S1303, the intermediate unit 202A determines, based on the command value 1001 of the control command information 1010, one or more individual identification values that the main control unit 201 extracts from three or more types of individual identification values. Is stored in the intermediate storage unit 332 or the like, and the process proceeds to step S1304.

  In step S1304, intermediate unit 202A determines whether or not authentication information (authentication information signal) 1020 has been received from main control unit 201 by intermediate-side receiving unit 331. If the intermediate unit 202A determines that the authentication information 1020 has not been received (S1304: No), the process proceeds to step S1311. On the other hand, if the intermediate unit 202A determines that the authentication information 1020 has been received (S1304: Yes), the process proceeds to step S1305.

  In step S1305, the intermediate unit 202A decrypts the received authentication information 1020 with a decryption method corresponding to the encryption method of the main control unit 201, extracts authentication data from the data unit 1022 of the authentication information 1020, and One or a plurality of authentication history data obtained by removing one or a plurality of expected values that match the individual identification value indicated by the identification result from the authentication data based on the additional method data is stored in the intermediate storage unit 332, and then The process proceeds to step S1306. If encryption is not required between the main control unit 201 and the intermediate unit 202A, the decryption process in step S1305 is deleted.

  In step S1306, the intermediate unit 202A compares the extracted one or more authentication history data with the latest intermediate history data stored in the intermediate storage unit 332, and matches the intermediate history data. The determination result as to whether or not history data exists is stored in the intermediate storage unit 332 and the like, and then the process proceeds to step S1307.

  If the intermediate unit 202A determines in step S1307 that there is matching authentication history data (S1307: Yes), the history data matches the intermediate history data, and the continuity of communication is valid. In step S1308, authentication of the main control unit 201 is established, intermediate authentication result data indicating the establishment of authentication based on the history is generated and stored in the RAM 233 and the like, and then the process proceeds to step S1310. On the other hand, if the intermediate unit 202A determines that there is no matching authentication history data (S1307: No), the continuity of communication is not valid, or the authentication information is invalid, and thus step S1309. The authentication for the main control unit 201 is not established, intermediate authentication result data indicating that the authentication is not established is generated and stored in the RAM 233 or the like, and then the process proceeds to step S1310.

  In step S1310, the intermediate unit 202A sets the generated intermediate authentication result data in the result unit 1032 to generate intermediate authentication result information 1030, and generates an intermediate authentication result signal with the intermediate authentication result information 1030 added thereto. The transmission is performed from the intermediate transmission unit 337 to the peripheral unit 202B, and then the process proceeds to step S1311.

  In step S1311, the intermediate unit 202A determines whether or not the pachinko gaming machine 100 is powered off. If the intermediate unit 202A determines that the power is not turned off (S1311: No), the intermediate unit 202A returns to the process of step S1301 and repeats a series of processes. On the other hand, when it is determined that the power is turned off (S1311: Yes), the intermediate unit 202A ends the process according to this flowchart.

  In the present embodiment, the case where the intermediate unit 202A extracts all of the plurality of authentication history data and then collectively compares them with the intermediate side history data has been described, but instead of this, one authentication history data is stored. It can also be set as the Example compared with intermediate | middle side historical data, whenever it extracts.

  Next, the procedure of receiving various control signals and intermediate authentication result signals by the CPU 241 (third computer) of the peripheral unit 202B will be described with reference to the flowchart of FIG.

  In step S1401, the peripheral unit 202B determines whether a control signal (control command information 1010) is received from the intermediate unit 202A. If the peripheral unit 202B determines that the control signal has been received (S1401: Yes), in step S1402, the peripheral unit 202B performs predetermined processing based on the command value 1001 and the accompanying data 1002 included in the received control signal, and then the step The process proceeds to S1405.

  On the other hand, when it is determined that the peripheral unit 202B has not received the control signal (S1401: No), the intermediate unit 202A is determined based on whether or not the received signal has the identification unit 1031 in step S1403. It is determined whether or not an intermediate authentication result signal has been received. If the peripheral unit 202B determines that the intermediate authentication result signal has not been received (S1403: No), the process proceeds to step S1405. On the other hand, if it is determined that the intermediate authentication result signal is received (S1403: Yes), the peripheral unit 202B proceeds to the process of step S1404.

  In step S1404, the peripheral unit 202B refers to the result unit 1032 of the received intermediate authentication result signal, and determines whether or not the intermediate authentication result signal indicates that authentication has been established. If the peripheral unit 202B determines that the intermediate authentication result indicates that authentication has been established (S1404: Yes), the peripheral unit 202B stores the authentication result in the RAM 243 or the like, and then proceeds to the processing of step S1405.

  In step S1405, the peripheral unit 202B determines whether or not the pachinko gaming machine 100 is powered off. If it is determined that the power is not turned off (S1405: No), the peripheral unit 202B returns to the process of step S1401 and repeats a series of processes. On the other hand, when it is determined that the power is turned off (S1405: Yes), the peripheral unit 202B ends the process according to this flowchart.

  On the other hand, if it is determined in step S1404 that the intermediate authentication result does not indicate that the authentication is successful (S1404: No), the peripheral unit 202B outputs a notification signal from, for example, the speaker 262 (see FIG. 2) or the like in step S1406. Then, the process according to this flowchart is terminated. As for the processing of the peripheral portion 202B when the intermediate authentication result does not indicate that authentication has been established, that is, when authentication has not been established, the processing of the peripheral portion 202B is continued only by outputting a notification signal. Also good.

(Example of authentication process)
Next, in the pachinko gaming machine 100, when the intermediate part 202A of the main control board 310 and the peripheral board 330 uses the above four individual identification values UA, UB, UC, UD and expected values VA, VB, VC, VD. An example of authentication will be described with reference to the drawing of FIG.

  First, as a precondition, the main control board 310 prestores four individual identification values UA, UB, UC, and UD in the data storage unit 311 and sets the addition method to “+”. On the other hand, the intermediate section 202A of the peripheral board 330 stores in the intermediate storage section 332 four expected values VA, VB, VC, VD that match the individual identification values UA, UB, UC, UD of the main control board 310 in advance. In addition, it is stored that the addition method of the main control board 310 is “+”. That is, the intermediate portion 202 </ b> A of the peripheral board 330 stores “−” which is an addition method opposite to the main control board 310. Further, the control command information 1010 has the same configuration as that shown in FIG.

  In FIG. 18, when the main control board 310, which is a person to be authenticated, transmits a control command CA to the intermediate section 202 </ b> A of the peripheral board 330 according to the operation of the pachinko gaming machine 100, the control command CA is stored in the data storage section 311. (S1501). Then, the main control board 310 generates history data based on the transmitted control command CA and the history generation method and stores it in the data storage unit 311 (S1502). The main control board 310 calculates a logical product of the command value 1001 (0x00) of the control command CA and a random value, and stores the calculation result of 0x00 in the RAM 213 or the like (S1503). Since the calculation result is 0x00, the main control board 310 extracts the individual identification value UA (see FIG. 12) whose relative address is 0x00 and stores it in the RAM 213 or the like (S1504).

  On the other hand, upon receiving the control command CA, the intermediate unit 202A of the peripheral board 330 stores the control command CA in the intermediate storage unit 332 and transfers the control command CA to the peripheral unit 202B of the peripheral board 330 (S1551). ). Then, similar to the main control board 310, the intermediate unit 202A generates intermediate history data based on the received control command CA and the history generation method, and stores the intermediate history data in the intermediate storage unit 332 (S1552). Since the command value 1001 of the control command CA is 0x00, the intermediate unit 202A specifies one individual identification value UA that can be extracted by the main control board 310 among the individual identification values UA, UB, UC, and UD ( S1553). On the other hand, when the peripheral unit 202B receives the control command CA, the peripheral unit 202B performs a predetermined process corresponding to the control command CA (S1581).

  Thereafter, the main control board 310 generates authentication information 1020 having authentication data C1 obtained by adding (adding) the extracted individual identification value UA to the latest history data, and transmits it to the intermediate section 202A of the peripheral board 310 (S1505). ). On the other hand, the intermediate portion 202A of the peripheral board 330 subtracts (removes) the expected value VA corresponding to the identified individual identification value UA from the authentication data C1 of the received authentication information 1020, and the authentication history data C1-VA. And authentication based on continuity of communication of the control command information 1010 with the main control board 310 is performed based on whether or not the authentication history data C1-VA matches the latest intermediate history data ( S1554). Then, the intermediate unit 202A generates intermediate authentication result data indicating the authentication result and transmits it to the peripheral unit 202B of the peripheral board 330 (S1555).

  When the main control board 310 transmits the next control command CD to the intermediate section 202A of the peripheral board 330, the main control board 310 stores the control command CD in the data storage section 311 (S1506). The main control board 310 generates history data based on the transmitted control command CD and the history generation method, and stores the history data in the data storage unit 311 (S1507). When the acquired random number value is 0x02, the main control board 310 performs a logical product operation of the command value 1001 (0x03) of the control command CD and the random value (0x02), and the operation result of 0x02 is stored in the RAM 213. (S1508). Since the calculation result is 0x02, the main control board 310 extracts the individual identification value UC (see FIG. 12) whose relative address is 0x02 and stores it in the RAM 213 or the like (S1509).

  On the other hand, when receiving the control command CD, the intermediate section 202A of the peripheral board 330 stores the received control command CD in the intermediate storage section 332 and transfers the control command CD to the peripheral section 202B of the peripheral board 330. (S1556). Then, similar to the main control board 310, the intermediate unit 202A generates intermediate history data based on the received control command CD and the history generation method, and stores the intermediate history data in the intermediate storage unit 332 (S1557). Since the command value 1001 of the control command CD is 0x03, the intermediate unit 202A specifies that the main control board 310 can extract all four individual identification values UA, UB, UC, and UD (S1558).

  On the other hand, when the peripheral unit 202B receives the control command CD while receiving the intermediate authentication result data indicating that the authentication has been established, the peripheral unit 202B performs a predetermined process corresponding to the control command CD (S1582).

  Thereafter, the main control board 310 generates authentication information 1020 having authentication data C2 obtained by adding (adding) the extracted individual identification value UC to the latest history data, and transmits it to the intermediate section 202A of the peripheral board 310 (S1510). ). On the other hand, the intermediate portion 202A of the peripheral board 330 has the expected values VA, VB, VC, VD corresponding to the four identified individual identification values UA, UB, UC, UD from the authentication data C2 of the received authentication information 1020. Each of the authentication history data C2-VA, C2-VB, C2-VC, C2-VD is extracted by subtracting (removing), and the authentication history data C2-VA, C2-VB, C2-VC, C2 is extracted. Based on whether -VD and the latest intermediate history data match, authentication is performed based on continuity of communication of control command information with the main control board 310 (S1559). The intermediate unit 202A generates intermediate authentication result data indicating the authentication result and transmits it to the peripheral unit 202B of the peripheral substrate 330 (S1560).

  When the main control board 310 transmits the next control command CB to the intermediate section 202A of the peripheral board 330, the main control board 310 stores the control command CB in the data storage section 311 (S1511). Then, the main control board 310 generates history data based on the transmitted control command CB and the history generation method, and stores it in the data storage unit 311 (S1512). When the acquired random number value is 0x01, the main control board 310 performs an AND operation between the command value 1001 (0x01) of the control command CB and the random value (0x01), and the operation result of 0x01 is stored in the RAM 213. (S1513). Since the calculation result is 0x01, the main control board 310 extracts the individual identification value UB (see FIG. 12) whose relative address is 0x01 and stores it in the RAM 213 or the like (S1514).

  On the other hand, when receiving the control command CB, the intermediate unit 202A of the peripheral board 330 stores the received control command CB in the intermediate storage unit 332 and transfers the control command CB to the peripheral unit 202B of the peripheral board 330. (S1561). Then, similarly to the main control board 310, the intermediate unit 202A generates intermediate history data based on the received control command CB and the history generation method, and stores it in the intermediate storage unit 332 (S1562). Since the command value 1001 of the control command CB is 0x01, the intermediate unit 202A has two individual identification values UA and UB that can be extracted by the main control board 310 among the four individual identification values UA, UB, UC, and UD. Is specified (S1563).

  On the other hand, when the peripheral unit 202B receives the control command CB while receiving the intermediate authentication result data indicating that authentication has been established, the peripheral unit 202B performs a predetermined process corresponding to the control command CB (S1583).

  Thereafter, the main control board 310 generates authentication information 1020 having authentication data C3 obtained by adding (adding) the extracted individual identification value UB to the latest history data, and transmits it to the peripheral board 310 (S1515). On the other hand, the intermediate portion 202A of the peripheral board 330 subtracts (removes) the expected values VA and VB corresponding to the two identified individual identification values UA and UB from the authentication data C3 of the received authentication information 1020. ) The authentication history data C3-VA and C3-VB are extracted, and based on whether the authentication history data C3-VA and C3-VB match the latest intermediate history data, Authentication based on the continuity of communication of the control command information 1010 is performed (S1564). The intermediate unit 202A generates intermediate authentication result data indicating the authentication result and transmits it to the peripheral unit 202B of the peripheral board 330 (S1565). Thereafter, the same processing is performed.

  According to the pachinko gaming machine 100 described above, the main control board 310 only calculates the command value 1001 and the random number value of the existing control command information 1010, and three types of individual identification values corresponding to the calculation result are obtained. Since the authentication information 1020 is extracted from the above individual identification values, and the extracted individual identification value is added to the history data, and transmitted to the intermediate portion 202A of the peripheral board 330, the intermediate portion 202A However, even if the history data of the authentication information 1020 is used for authentication of the main control board 310, the individual identification value added to the history data irregularly changes depending on the random value, so that the regularity of the authentication information 1020 is lost, and the authentication information It can be expected that illegal analysis of 1020 is prevented. Moreover, the intermediate unit 202A extracts the authentication history data from the authentication information 1020 using only the expected value corresponding to the command value 1001 of the control command information 1010 for the three or more types of expected values, and the extracted authentication data Since the authentication of the main control board 310 is performed based on the determination result of whether or not the history data matches the intermediate history data, the extraction target of the main control board 310 is determined by a plurality of different command values 1001. Even when the pattern is changed, the main control board 310 does not need to determine (recognize) the change, and the intermediate portion 202A of the peripheral board 330 can bear the processing related to the authentication of the main control board 310. The pattern to be extracted can be switched in cooperation with a plurality of types of command values 1001, and fraud analysis on the authentication information 1020 It can be even more difficult. Furthermore, since the main control board 310 can store three or more types of individual identification values in advance, it is not necessary to perform complicated calculations when generating the authentication information 1020, and the processing load on the main control board 310 is increased. Can be prevented. On the other hand, since the intermediate part 202A of the peripheral board 330 confirms and authenticates the communication continuity of the control command information 1010 based on the history data, the intermediate part 202A detects unauthorized communication switching due to unauthorized control command information. Therefore, it is possible to contribute to prevention of unauthorized communication switching. Moreover, since the intermediate unit 202A extracts the authentication history data from the authentication information 1020 using one or more expected values, when the regular individual identification value is not added to the history data, the authentication history data and Since the intermediate history data does not match, fraud can be reliably detected. In addition, for example, when an illegal substrate or the like intervenes between the main control substrate 310 and the intermediate portion 202A of the peripheral substrate 330, the processing load must be increased because the analysis load on the unauthorized substrate increases. It is possible to increase the cost and the degree of design difficulty and contribute to the inhibition of the production of illegal substrates. Further, since the intermediate unit 202A performs the authentication process on the main control board 310 and transmits the intermediate authentication result to the peripheral unit 202B, the peripheral unit 202B only refers to the intermediate authentication result without performing the authentication process. Therefore, the processing load on the CPU 241 in the peripheral portion 202B can be reduced. Since the intermediate unit 202A manages the history of the control command information 1010 from the main control board 310, the peripheral unit 202B does not need to manage the history of the control command information 1010. An increase in the processing load of 202B can be prevented. Moreover, since the intermediate unit 202A transmits the control command information 1010 from the main control board 310 to the peripheral unit 202B as it is, the peripheral unit 202B may perform a predetermined process at the same time as the intermediate unit 202A performs the authentication process. Therefore, it is possible to prevent the predetermined process in the peripheral portion 202B from being delayed. Therefore, it is possible to check the communication continuity of the control command information 1010 by using an existing configuration and minimizing an increase in the processing load of the main control board 310, making it difficult to analyze the authentication information 1020 used for authentication. And the processing load on the CPU 241 in the peripheral portion 202B can be reduced.

  Further, according to the pachinko gaming machine 100 described above, the main control board 310 calculates the command value and the random number value even when the number of individual identification values to be extracted and the extraction pattern are different, and calculates the individual identification value from the calculation result. Since it is only necessary to execute a common process of extraction, the process of the main control board 310 can be simplified as compared with the case where the number of individual identification values to be extracted and the process for each extraction pattern are performed.

  Further, the pachinko gaming machine 100 described above identifies, for each of a plurality of types of control command information 1010, a command value for identifying the control command information 1010 and specifying one individual identification value by calculation with a random value. Therefore, the main control board 310 only needs to calculate the command value and the random number value, and the processing of the main control board 310 can be simplified, so that the data amount of the program can be reduced.

  Note that the control method of the main control unit and the intermediate unit described in the present embodiment can be realized by executing a program prepared in advance on a computer such as a personal computer or a workstation. This program is recorded on a computer-readable recording medium such as a hard disk, CD-ROM, MO, DVD, and the like, and is executed by being read from the recording medium by the computer. The program may be an electric transmission medium that can be distributed via a network such as the Internet.

  As described above, the present invention is useful for an electronic device in which fraud to the main control unit is a concern and a gaming machine on which the electronic device is mounted, and in particular, a pachinko gaming machine, a slot gaming machine, and a sparrow ball gaming machine. It can be applied to various other gaming machines. 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.
