Description

  The present invention relates to a gaming machine including a plurality of boards and performing communication authentication between these boards and a gaming machine authentication method.

  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 a control command 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, in Patent Document 2, a control command is transmitted from the main control board to the sub control board, and further, a state monitoring command for monitoring the communication state of the control command in a predetermined communication path is transmitted. A configuration is described in which the validity of a control command is verified using a monitoring command and control of a control target is stopped 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.

  In addition, as in Patent Document 2 described above, when a state monitoring command different from the control command is transmitted from the main control board to the controlled board, the gaming machine may be cheated ("got" action). Yes, since the state monitoring command is likely to be illegally analyzed 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. 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.

  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 gaming machine authentication method of the present invention described in claim 7, the main control unit assigns the individual identification value to the main control unit when the gaming machine is started, when a predetermined event occurs, or the like. Based on the predetermined storage data, it is generated and stored in the individual identification value storage means. When the main control unit transmits a control command to the peripheral unit via the intermediate unit according to the operation of the gaming machine, the main control unit generates history data indicating the history by the history generation method. The main control unit generates authentication information having the history data as authentication data and transmits it to the intermediate unit. In addition, when the main control unit randomly determines to switch the history generation method, the main control unit generates authentication information having the individual identification value stored in the individual identification value storage unit as authentication data and transmits it to the intermediate unit, The history generation method can be switched by a predetermined switching method from a plurality of predetermined history generation methods. On the other hand, in the intermediate part, an expected value that matches the individual identification value of the main control part is stored in advance in the expected value storage means at the time of manufacture or the like. When the intermediate unit receives the control command from the main control unit, the intermediate unit transmits the control command to the peripheral unit, and the intermediate side history data indicating the history of the control command received from the main control unit is the same as the main control unit. It is generated by the history generation method. Then, when receiving the authentication information from the main control unit, the intermediate unit indicates the authentication result of the main control unit determined based on whether the authentication data of the authentication information matches the expected value or the intermediate side history data. Intermediate authentication result data is generated and transmitted to the peripheral part. When the authentication data matches the expected value, the intermediate unit can similarly switch the history generation method using the same switching method as that of the main control unit. On the other hand, the peripheral unit can perform a predetermined process in the gaming machine based on the control command 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, since the main control unit generates the individual identification value, it is not necessary to previously store the individual identification value in the main control unit. An increase in the amount of data stored in advance for authentication of the control unit can be suppressed. Further, even if the data of the main control unit is illegally analyzed, the generated individual identification value is not stored in advance, which can contribute to prevention of illegal analysis for the authentication of the main control unit. Then, the main control unit transmits the authentication information having either one of the history data indicating the history of the control command or the individual identification value to the intermediate unit, and generates the history data in response to the transmission of the authentication information having the individual identification value. Since the history generation method is switched, history data can be generated by switching the history generation method, so that it is difficult to analyze the generation method of the history data, and the authentication information includes the history data. It can be difficult to guess whether it has an individual identification value. In addition, since the intermediate unit only has to switch the history generation method of the intermediate history data in the same way as the main control unit in response to the reception of the authentication information having the individual identification value, it is easy to synchronize with the main control unit and illegal authentication information When this occurs, the history generation methods do not match, which can contribute to prevention of fraud. And since the intermediate unit is configured to check and authenticate the communication continuity of the control command based on the history data, it is possible to detect unauthorized communication switching due to an unauthorized control command. Can be prevented from being transmitted to the peripheral portion, which can contribute to prevention of unauthorized communication switching. And since the history generation method is switched, the continuity of the history data to be generated is lost, and even if the control command and the history generation method are analyzed illegally, the control command appearance order and the history data appearance Since it becomes difficult to guess the relevance (correspondence etc.) with the order, it is possible to prevent an unauthorized analyst from using authentication information illegally. In addition, since the intermediate unit performs the authentication process 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. Furthermore, since the main control unit generates an individual identification value between the time when the gaming machine is activated and the time when the authentication information is generated and stores it in advance, it is not necessary to perform a complicated operation when generating the authentication information. An increase in processing load on the main control unit can be prevented. In addition, since the intermediate unit manages the history of control commands from the main control unit, it does not require control command history management in the peripheral unit, thus preventing an increase in processing load on the peripheral unit due to improved security. can do. In addition, since the intermediate unit transmits the control command from the main control unit to the peripheral side as it is, the peripheral unit can perform the predetermined process at the same time as the intermediate unit performs the authentication process. It is possible to prevent a delay in the processing. Therefore, it is possible to confirm the communication continuity of the control command, to make it difficult to analyze the authentication information used for authentication, and to reduce the processing load on the peripheral CPU.

  In the gaming machine described above, the main control unit and the intermediate unit count the number of occurrences and receptions of individual identification values, and switch the history generation method using the switching method when the number of times satisfies the switching condition. Since the continuity of the generated history data and the switching timing of the history generation method can be further complicated, unauthorized analysis can be made more difficult.

  In the gaming machine described above, switching information is associated with a plurality of individual identification values of the main control unit and a plurality of expected values of the intermediate unit, and the history generation method is switched based on the switching information. Since the continuity of the generated history data and the switching timing of the history generation method can be further complicated, unauthorized analysis can be made more difficult. In addition, since it becomes difficult to estimate whether the authentication information has history data or an individual identification value, unauthorized use of the authentication information can be prevented.

  In the gaming machine described above, since the history data and the intermediate history data indicate the history of the control command for a plurality of times, even if the number of authentication information transmissions is reduced, the control command fraud that occurred during that time is detected. Therefore, it is possible to improve the authentication accuracy. Further, since the history data is complicated, unauthorized analysis can be made more difficult.

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 a control command for operating the peripheral board 330, and includes a data storage unit 311, an individual identification value generation unit 312, a history data generation unit 313, a selection unit 314, and an authentication information generation unit. 315, a switching unit 316, and a main control side transmission unit 317. The main control board 310 is formed of a board different from the peripheral board 330, and is electrically connected so as to be communicable with the intermediate portion 202A of the peripheral board 330.

  The data storage unit 311 corresponds to the individual identification value storage unit of the present invention, and includes control command data (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 a history generation method) and switching information 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 control commands and a plurality of authentication information transmitted to the intermediate unit 202A in a time series as log data. The number of control commands and authentication information stored in the data storage unit 311 can be arbitrarily set. Further, the timing of storing the control command and authentication information in the data storage unit 311 can be arbitrarily determined when it is determined, after being transmitted to the intermediate unit 202A, and the like. The history generation method data indicates a history generation method used by the history data generation unit 313, and an initial value is set at the time of startup or the like, and thereafter, the switching unit 316 performs switching.

  The data storage unit 311 stores at least the generated individual identification value among the individual identification value generated by the individual identification value generation unit 312 described later and a predetermined individual identification value. The individual identification value is a value used by the intermediate unit 202A of the peripheral board 330 for authentication by individual identification of the main control board 310 (main control unit). In the present embodiment, the case where the data storage unit 311 stores only the individual identification value generated by the individual identification value generation unit 312 will be described, but instead of this, the generated individual identification value is predetermined. It can also be set as the Example which memorize | stores both an individual identification value.

  The individual identification value generation unit 312 corresponds to the individual identification value generation unit of the present invention, and generates an individual identification value for identifying the main control board 310 based on predetermined storage data of the main control board 310. . The individual identification value generation unit 312 generates an individual identification value using the storage data and one or a plurality of predetermined individual identification value generation methods. Therefore, an expectation that matches the individual identification value to be generated by the main control board 310 If the value is stored in the peripheral board 330, the intermediate portion 202A of the peripheral board 330 authenticates the individual identification of the main control board 310 by determining whether or not the individual identification value matches the expected value. be able to.

  The stored data is unique data of the main control unit 310 stored in advance in the ROM 212 of the main control unit 201. Examples of stored data include program data executed by the CPU 211 of the main control unit 310, fixed data dedicated for authentication, etc., in which case the data is determined by the time of manufacturing the pachinko gaming machine 100, etc. Will do. Since the stored data is stored in the data storage unit 311, the data storage unit 311 stores the stored data as stored data storage means. Also, the jackpot related program data (a part of the program data stored in the ROM 212) for the main control board 310 to control the jackpot in the pachinko gaming machine 100 may be illegally rewritten. By using the stored data having the program data, the individual identification value generated by the individual identification value generation unit 312 and the expected value of the intermediate unit 202A do not match, so that the occurrence of unauthorized rewriting can be detected.

  The individual identification value generation unit 312 generates an individual identification value at a predetermined generation timing. Examples of the generation timing include when the pachinko gaming machine 100 is activated, when a predetermined control command is generated or when a predetermined number of times are generated, a predetermined time, every time the main control board 310 is authenticated, and the like. . Each time the main control board 310 is authenticated means a timing for generating authentication information to be described later.

  As an example of an individual identification value generation method of the individual identification value generation unit 312, a checksum of stored data in different predetermined areas (ranges) in the ROM 212, a total value of odd or even addresses in each predetermined area, For example, stored values extracted from a plurality of different predetermined addresses may be used. Note that the generation timing and the individual identification value generation method of the individual identification value generation unit 312 can be set differently for each type of pachinko gaming machine 100, each specification, and the like. The individual identification value generation method of the individual identification value generation unit 312 is a generation method different from the history generation method of the history data generation unit 313 described later so that the individual identification value and the history data do not match. In addition, the design can be performed in consideration of, for example, different bit assignments, generation ranges, and the like.

  In addition, if the individual identification value generation unit 312 is an example in which a plurality of individual identification value generation methods are randomly switched using random numbers or the like, a plurality of individual identification values can be used for authentication information. Even if the control board 310 is illegally analyzed, since a plurality of individual identification values do not exist in the main control board 310, it becomes difficult to perform an illegal analysis on the individual identification values, which contributes to prevention of illegal analysis on the main control unit 201. be able to. In this case, a plurality of expected values that match all the individual identification values generated by the plurality of individual identification value generation methods can be stored in the intermediate portion 202A of the peripheral board 330 in advance. Since the individual identification value stored in advance in the ROM 212 of the main control unit 201 can be reduced as the number of individual identification values generated by the individual identification value generation unit 312 increases, the main control in the pachinko gaming machine 100 can be reduced. It is possible to suppress an increase in the amount of data stored in the ROM 212 related to the authentication of the board 310 and to make unauthorized analysis on the main control board 310 even more difficult.

  In the present embodiment, the individual identification value generation unit and the individual identification value storage unit of the present invention are separately realized by the individual identification value generation unit 312 and the data storage unit 311. Instead, the individual identification value generating means and the individual identification value storage means can be realized integrally. For example, two means can be realized with one piece of hardware by causing the CPU 211 to function as an individual identification value generating unit and causing the register of the CPU 211 to function as an individual identification value storage unit. Alternatively, dedicated hardware having a circuit for realizing the individual identification value generating unit and the individual identification value storage unit may be used.

  The history data generation unit 313 corresponds to a history data generation unit of the present invention, and history data indicating a history of control commands transmitted from the main control board 310 to the intermediate part 202A of the peripheral board 330 is set as a predetermined history generation method. Generate with The history data generation unit 313 generates a history at a predetermined generation timing such as an arbitrary timing from the generation (determination) of the control command to the intermediate unit 202A of the control command in the pachinko gaming machine 100, for example. History data is generated and stored based on the method and the control command data stored in the data storage unit 311. Then, the history data generation unit 313 calculates control command data 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 a control command, for example, the control command that is the generation target of history data such as the retroactive number of transmitted single control commands, the retroactive range of plural types of control commands, etc. Is specified. When the history data generation unit 313 generates the history data as a checksum, the total value or history data for a single type of control command data is a total value obtained by summing the plurality of control command data. Note that the history data can use the control command for one time such as the previous time or a predetermined number of times as it is, thereby simplifying the process when generating authentication information, which will be described later.

  The history data generation unit 313 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 to the generated history data and stored. 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 313 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 transmission on the main control side The configuration is such that the unit 317 discards the authentication information having the history data without transmitting it. Alternatively, the history data generation unit 313 may be designed to generate history data having a value different from the individual identification value, or may be implemented in various different embodiments such as corresponding to the bit adjustment of the history data.

  The selection unit 314 corresponds to the selection unit of the present invention, and the individual identification value stored in the data storage unit (individual identification value storage unit) 311 and the history data generated by the history data generation unit (history data generation unit) 312. Either of these is selected at random. The selection unit 314 uses a random number or the like so that the selection frequency between the individual identification value and the history data becomes random. Then, the selection unit 314 can adjust the selection frequency by setting a random number or the like. For example, by setting a random number or the like so that only one out of ten selections becomes an individual identification value and increasing the selection frequency of history data, the continuity of communication of control commands is intensively monitored. Therefore, detection of unauthorized communication switching can be expected. In the present invention, since the history generation method is switched according to the occurrence of the individual identification value, the frequency of switching the history generation method can be increased by setting the selection frequency of the individual identification value high. It is possible to increase the difficulty of a simple analyst analyzing the switching timing.

  The authentication information generation unit 315 corresponds to the authentication information generation unit of the present invention, and the authentication information used by the intermediate unit 202A for authentication of the main control unit 201 is the individual identification value or history data selected by the selection unit (selection unit) 314. One of the above is generated as authentication data. In other words, when history data is selected by the selection unit 314, the authentication information generation unit 315 generates authentication information in which history data is set in the authentication data of the authentication information. In addition, when the individual identification value is selected by the selection unit 314, the authentication information generation unit 315 generates authentication information in which the individual identification value is set in the authentication data of the authentication information. Therefore, the authentication information has authentication data, and either one of history data or individual identification value is set in the authorization data.

  The switching unit 316 corresponds to the switching unit of the present invention. When the selection unit (selection unit) 314 selects an individual identification value, the history generation method of the history data generation unit (history data generation unit) 313 is determined in advance. The plurality of history generation methods are switched by a predetermined switching method, and the history generation method data in the data storage unit 311 is set. For example, the switching unit 316 can switch between two types of history generation methods, or switch a plurality of history generation methods in order.

  The main control side transmission unit 317 corresponds to the main control side transmission unit of the present invention, and includes authentication information generated by the authentication information generation unit 315 and a plurality of control command data for controlling the peripheral portion 202A of the peripheral board 330. Each is transmitted to the intermediate portion 202A of the peripheral board 330. Then, the main control side transmission unit 317 of this embodiment transmits control command data from the main control board 310 to the intermediate part 202A of the peripheral board 330 as a control signal. For example, the main control side transmission unit 317 transmits 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 receiving unit 331, an intermediate storage unit 332, an intermediate history data generation unit 333, an intermediate authentication result data generation unit 334, an intermediate transmission unit 335, and an intermediate switching unit 336. Configured.

  The intermediate receiving unit 331 corresponds to the intermediate receiving unit of the present invention, and receives authentication information, control command data (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. Further, when receiving the control signal from the main control unit 201 separately from the authentication information signal, the intermediate receiving unit 331 transmits the control signal as it is from the intermediate transmitting unit 335 described later 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 commands 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. Yes.

  The intermediate storage unit 332 receives one or more individual identification values to be received from the main control board 310 described above, that is, an expected value that matches the individual identification value stored in the data storage unit 311 of the main control board 310. I remember it. Thereby, the intermediate part 202A of the peripheral substrate 330 can determine that the authentication data is a regular individual identification value if the authentication data set in the authentication information matches the expected value. Further, if the authentication data set in the authentication information does not match the expected value, it can be determined that it is not an individual identification value. The expected value is calculated based on the storage data of the main control board 310 and the generation method at the time of designing or manufacturing the pachinko gaming machine 100, and the intermediate value at the time of manufacturing the pachinko gaming machine 100, for example. It is stored in advance in the ROM 232 of the storage unit 332 or the like. The expected value can be stored in advance as a part of the program executed by the CPU 231 of the intermediate unit 202A.

  The intermediate storage unit 332 stores history generation method data similar to that of the main control unit 201. The history generation method data indicates a history generation method used by the intermediate-side history data generation unit 333, and an initial value is set at the time of startup or the like, and thereafter, the intermediate-side switching unit 336 performs switching.

  The intermediate history data generation unit 333 corresponds to the intermediate history data generation means of the present invention, and the intermediate history data indicating the history of the control command received from the main control board 310 is the same as the history generation of the main control board 310. Generate by method. The intermediate-side history data generation unit 333 has the same history generation method and intermediate-side storage as the main control board 310 at a predetermined intermediate-side generation timing such as when a control command is received from the main control board 310, after receiving the control command. Based on the control command data stored in the unit 332, intermediate history data is generated and stored. That is, the intermediate-side history data generation unit 333 calculates control command data 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 data transmitted by the main control board 310 is received. It can be determined that data is being 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 intermediate authentication result data generation unit 334 corresponds to the intermediate authentication result data generation means of the present invention, and a determination result of whether or not the authentication data of the received authentication information matches the expected value or the intermediate history data The main control board (main control unit) 310 is authenticated based on the above, and intermediate authentication result data indicating the authentication result is generated and transmitted to the peripheral unit 202B. 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). When the authentication data matches the intermediate history data, the intermediate authentication result data generation unit 334 sets the history data in the authentication data, and the control command used to generate the intermediate history data is valid. Since it can be determined that there is, authentication is established. In addition, if the authentication data matches the expected value, the intermediate authentication result data generation unit 334 can determine that the individual identification value is set in the authentication data and the legitimate individual identification value has been received. Establish. That is, the intermediate authentication result data generation unit 334 establishes authentication of the main control board 310 when either the continuity of the communication state based on the received history data or the received determination result of the individual identification value is valid. . Note that the intermediate authentication result data generation unit 334 may be configured to establish authentication when it is determined that both the continuity of the communication state and the received individual identification value are valid.

  The intermediate side transmission unit 335 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 334 to the peripheral unit 202B. Then, the intermediate transmission unit 335 transmits the intermediate authentication result data generated by the intermediate authentication result data generation unit 334 to the peripheral unit 202B as an intermediate authentication result signal. Further, the intermediate transmission unit 335 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) to the intermediate unit 202A, thereby transmitting the control signal (control command) to the peripheral unit 202B via the intermediate unit 202A.

  The intermediate side switching unit 336 corresponds to the intermediate side switching unit of the present invention, and when the authentication data of the received authentication information matches the expected value, the history generation method of the intermediate side history data generation unit 333 is changed to the main control. Similarly to the switching unit 316 of the substrate 310, switching is performed by a predetermined switching method from a plurality of predetermined history generation methods. Therefore, since the switching unit 316 and the intermediate side switching unit 336 can switch the history generation method with the synchronized switching timing and the same switching method, unless the intermediate unit 202A of the peripheral board 330 receives unauthorized authentication information, There is no switching to a different history generation method.

  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 a control command, 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 a control command 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 according to the control command 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 indicated by the control signal received from the intermediate unit 202A, and indicates that authentication has not been established. Will alert you. The predetermined process is a process corresponding to a control command from the main control unit 201 in the pachinko gaming machine 100. For example, a loss process, a jackpot reach process, a jackpot start process, a jackpot round process, a jackpot end process, etc. Can be mentioned.

  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 the pachinko gaming machine 100 of the present invention, since the individual identification value is generated by the main control board 310 after the pachinko gaming machine 100 is started, the main control board 310 stores in advance an individual identification value for individual identification. Therefore, it is possible to make illegal analysis difficult. Also, authentication information in which either one of history data or individual identification value is set is transmitted from the main control board 310 to the intermediate part 202A of the peripheral board 330, and the intermediate part 202A of the peripheral board 330 is added to the history data of the authentication information. Based on this, a configuration is employed in which authentication is performed based on the continuity of communication of control commands, and authentication is performed based on the individual identification of the main control board 310 based on the individual identification value of the authentication information. Since the intermediate part 202A of the main control board 310 and the peripheral board 330 switches the history generation method by the same switching method according to the appearance of the authentication information having the individual identification value, the history data of the authentication information is changed. Since it can be changed irregularly, unauthorized analysis of authentication information can be made difficult. Therefore, even if the authentication information is independently transmitted from the main control unit 201 to the intermediate part 202A of the peripheral board 330, it can be difficult to easily analyze it.

  In the present embodiment, the CPU 211 of the main control board 310 is the first computer in the claims, and the CPU 231 of the intermediate section 202A of the peripheral board 330 is the second computer of the claims, and the CPU 241 of the effect control section 202B of the peripheral board 330. Will be described as functioning as the third computer in the claims. The ROM 212 of the main control board 310 includes various information such as individual identification value generation means, history data generation means, selection means, authentication information generation means, switching means, main control side transmission means, etc. A main control side authentication program for functioning as a means 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, intermediate authentication result data generating means, intermediate transmitting means, and intermediate switching means. The intermediate side authentication program for functioning as various means such as. Further, the ROM 242 of the peripheral portion 202B of the peripheral board 330 stores a peripheral side authentication program for causing the third computer to function as various means such as peripheral side receiving means and processing means in the claims. 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 status of the game ball for each winning port to the winning ball control unit 203 as a control command. The winning ball control unit 203 pays out the number of winning balls corresponding to the winning situation in accordance with the control command output from the main control unit 201.

  The main control unit 201 outputs a corresponding control command 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 on the symbol display unit 104 in a variable manner. Repeat to stop. The main control unit 201 outputs a corresponding control command to the effect control unit 202B when the occurrence of the jackpot is determined, and the effect control unit 202B aligns with a predetermined symbol and stops the variable display, Control is performed to open the special winning opening 109. 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 specific driving for various types of accessories and correction of 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 data) 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 processing, the effect control unit 202B controls the lamp control unit 251, the sound control unit 252, and the symbol display unit 104 for effect control at the time of power-on (specifically, Transmits a control command instructing lighting of a lamp, sound output, display of a demonstration (demo) screen, 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 commands of the present invention, and the main control board 310 stores the control command data in the data storage unit 311 as a history each time the various control commands are transmitted. ing. In response to the storage of the control command data, 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 data as a history in the intermediate storage unit 332 each time various control commands are received, and updates the intermediate history data in the intermediate storage unit 332. To do.

  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, a normal control signal 1010 has control command data 1001 and accompanying data 1002. The control command data 1001 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 control command data 1001, and is data necessary for processing based on the control command data 1001 such as the number of winning game balls, for example.

(Authentication information data format)
Next, an example in which an authentication information signal different from the control signal 1010 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 control command data 1001 by using a command different from the control command of the control command data 1001 described above.

  In the data part 1022, either the above-described history data or individual identification value is set as authentication data. The data unit 1022 of the present embodiment will be described in the case where either history data or individual identification value is set, but instead of this, the history data or individual identification value is associated with other data. The embodiment may be set in the unit 1022.

  That is, as shown in FIG. 12, the authentication information 1020 of the present embodiment is a data type K1 in which one type of “authentication command C” is set in the identification unit 1021 and history data is set in the data unit 1022. The authentication information 1020 is a data type K2 in which “authentication command C” is set in the identification unit 1021 and an individual identification value is set in the data unit 1022.

  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. When the result unit 1032 indicates that authentication is not established, the result unit 1032 has detailed data indicating details such as history data mismatch, individual identification value mismatch, and the like.

(Example of history generation method)
In the present embodiment, the history data generation unit 313 of the main control board 310 and the intermediate side history data generation unit 333 of the intermediate part 202A of the peripheral board 330 described above are based on the history generation method information shown in FIG. A case of switching will be described.

  The history generation method information shown in FIG. 13A is information used for switching between four calculation methods, for example, addition, subtraction, XOR, and XNOR. In this case, it is assumed that the control command to be calculated is predetermined. Next, the history generation method information illustrated in FIG. 13B is information used for switching four control commands, for example, a jackpot control command, a reach control command, and a loss control command. In this case, the calculation method for the corresponding control command is based on the premise that calculation methods such as addition, subtraction, XOR, and XNOR are determined in advance. Next, the history generation method information shown in FIG. 13C is information used when the control commands one, three, five, and five before the received control command are to be calculated. Similarly in this case, it is assumed that the calculation method is predetermined. Next, the history generation method information shown in FIG. 13 (d) is used to switch the retroactive number of control commands such that three received control commands are accumulated, five are accumulated, and ten are accumulated. It is used information. Similarly in this case, it is assumed that the calculation method is predetermined.

  The switching unit 316 and the intermediate side switching unit 336 switch a plurality of history generation methods indicated by the history generation method information using a predetermined common switching method. As an example of the switching method, there are sequentially switching from the top, specifying the switching order, specifying the switching pattern, and the like. For example, when sequentially switching the history generation method information of FIG. 13A, first, the “addition” history generation method is used, and then the next “subtraction” history generation method according to the generation of the individual identification value. Switch to Further, when the history generation method information in FIG. 13A is switched by the switching pattern, the switching pattern is switched to the first, third, second, and fourth. Thus, if the switching method can be used in common, the switching method can be arbitrarily set.

(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 the flowchart of FIG.

  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. A value is generated and stored in the data storage unit 311 and then the process proceeds to step S1201. When the main control unit 201 uses a plurality of individual identification values and generates a part of them, a part of individual identification values are generated, and the remaining individual identification values that are not generated do not generate a predetermined value. The individual identification value.

  In step S1201, the main control unit 201 determines whether or not a control command is generated based on the control command stored in the data storage unit 311. If the main control unit 201 determines that a control command has not been generated (S1201: No), the main control unit 201 proceeds to the process of step S1203. On the other hand, if the main control unit 201 determines that a control command has been generated (S1201: Yes), in step S1202, the history generation method data in the data storage unit 311 and the control command to be generated by the history generation method. Based on the data, history data is generated and stored in the data storage unit 311, and then the process proceeds to step S 1203.

  In step S1203, the main control unit 201 determines whether it is a predetermined authentication timing. When the main control unit 201 determines that it is not the authentication timing (S1203: No), the main control unit 201 proceeds to the process of step S1211. On the other hand, if the main control unit 201 determines that it is the authentication timing (S1203: Yes), the process proceeds to step S1204.

  In step S1204, the main control unit 201 randomly selects one of history data / individual identification value based on a random number and the like, stores the selection result in the RAM 213, and then proceeds to the processing of step S1205. Then, the main control unit 201 determines whether or not history data has been selected in step S1205. If the main control unit 201 determines that history data has been selected (S1205: Yes), in step S1206, authentication information (history) in which the authentication command C is set in the identification unit 1021 and the history data as authentication data is set in the data unit 1022. Data) 1020 is generated and stored in the data storage unit 311, and then the process proceeds to step S 1209.

  On the other hand, if the main control unit 201 determines that no history data has been selected (S1205: No), in step S1207, an authentication command C is set in the identification unit 1021, and an individual identification value as authentication data is set in the data unit 1022. The generated authentication information (individual identification value) 1020 is generated and stored in the data storage unit 311, and then the process proceeds to step S 1208. In step S1208, the main control unit 201 switches one history generation method from a plurality of predetermined history generation methods using the switching method, and the data storage unit 311 so that the switched history generation method is obtained. The history generation method data is updated, and then the process proceeds to step S1209.

  In step S1209, 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 S1210, based on the encrypted authentication information 1020. Then, an authentication information signal is generated and transmitted from the main control side transmitting unit 317 to the intermediate unit 202A of the peripheral board 330, and then the process proceeds to step S1211. If encryption is not required between the main control unit 201 and the intermediate unit 202A, the processing in step S1209 is deleted, and the authentication information 1020 is transmitted to the intermediate unit 202A as it is.

  In step S1211, 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 (S1211: 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 (S1211: Yes), the process according to this flowchart ends.

  Next, the authentication information signal reception processing procedure performed 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. 15, the intermediate-side receiving unit 331 determines whether or not the intermediate-side receiving unit 331 has received a control command from the main control unit 201 in step S1301. If the intermediate unit 202A determines that the control command has not been received (S1301: No), the process proceeds to step S1304. On the other hand, if the intermediate unit 202A determines that a control command has been received (S1301: Yes), in step S1302, the received control command (control signal) is stored in the intermediate storage unit 332 and the control command Is transferred to the peripheral portion 202B, and then the process proceeds to step S1303. Then, in step S1303, the intermediate unit 202A, based on the history generation method data in the intermediate storage unit 332 and the control command data to be generated by the history generation method, in the same manner as the main control unit 201, Is stored in the intermediate storage unit 332, and then 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 it is determined that the authentication information 1020 has not been received (S1304: No), the intermediate unit 202A proceeds to the process of step S1313. 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 using a decryption method corresponding to the encryption method of the main control unit 201, extracts the authentication data from the data unit 1022 of the authentication information 1020, and performs intermediate processing. It memorize | stores in the side memory | storage part 332, and it progresses to the process of step S1306 after that. 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 determines that the authentication data is the history data (based on the determination result of whether or not the received authentication data matches the intermediate history data stored in the intermediate storage unit 332). It is determined whether it is intermediate side history data). If the intermediate unit 202A determines that the authentication data is history data (S1306: Yes), the control command received from the main control unit 201 is valid, and the continuity of communication is valid. In step S1307, authentication based on history data for the main control unit 201 is established, intermediate authentication result data indicating authentication establishment based on the history is generated and stored in the RAM 233 and the like, and then the process proceeds to step S1312.

  On the other hand, if the intermediate unit 202A determines that the authentication data is not history data (S1306: No), the authentication data and the expected value stored in advance in the intermediate storage unit 332 match in step S1308. It is determined whether or not. If the intermediate unit 202A determines that the authentication data and the expected value match (S1308: Yes), the individual identification value received from the main control unit 201 is a normal one. In step S1309, the individual unit Authentication based on the identification value is established, intermediate authentication result data indicating establishment of authentication based on the individual identification value is generated and stored in the RAM 233 or the like, and then the process proceeds to step S1310. Then, in step S1310, the intermediate unit 202A switches one history generation method among a plurality of predetermined history generation methods using the switching method in the same manner as the main control unit 201, and the switched history generation method and The history generation method data in the intermediate storage unit 332 is updated so that the process proceeds to step S1312. On the other hand, if the intermediate unit 202A determines that the authentication data does not match the expected value (S1308: No), the authentication data does not match any of the intermediate side history data and the expected value, so in step S1311, 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 S1312.

  In step S1312, 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. Transmission is performed from the intermediate transmission unit 335 to the peripheral unit 202B, and then the process proceeds to step S1313.

  In step S1313, the intermediate unit 202A determines whether or not the pachinko gaming machine 100 is powered off. If the peripheral portion determines that the power is not turned off (S1313: No), the processing returns to step S1301, and a series of processing is repeated. On the other hand, when it is determined that the power is turned off (S1313: Yes), the intermediate unit 202A ends the processing according to this flowchart.

  Next, a procedure for 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 or not the control signal 1010 has been received from the intermediate unit 202A. If it is determined that the control signal 1010 has been received (S1401: Yes), the peripheral unit 202B performs predetermined processing based on the control command data 1001 and the accompanying data 1002 included in the received control signal 1010 in step S1402. Thereafter, the process proceeds to step S1405.

  On the other hand, when it is determined that the peripheral unit 202B has not received the control signal 1010 (S1401: No), in step S1403, based on whether or not the received signal includes the identification unit 1031, the intermediate unit It is determined whether an intermediate authentication result signal is received from 202A. 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 authentication has been established (S1405: 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.

(History generation method switching procedure example)
Next, in the pachinko gaming machine 100, an example of a procedure when the intermediate part 202A of the main control board 310 and the peripheral board 330 sequentially switches between the first history generation method and the second history generation method will be described with reference to the drawing of FIG. I will explain.

  In FIG. 17, the main control board 310 that is the person to be authenticated generates an individual identification value in response to the activation of the pachinko gaming machine 100, and stores the generated individual identification value in the data storage unit 311 (S1500). Thereafter, when the main control board 310 transmits a control command to the intermediate section 202A of the peripheral board 330 according to the operation of the pachinko gaming machine 100, the main control board 310 stores the control command in the data storage section 311 (S1501). Then, the main control board 310 generates history data based on the transmitted control command and the first history generation method and stores it in the data storage unit 311 (S1502). On the other hand, when receiving the control command, the intermediate part 202A of the peripheral board 330 stores the control command in the intermediate storage part 332 and transfers the control command to the peripheral part 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 and the first history generation method, and stores it in the intermediate storage unit 332 (S1552). On the other hand, when the peripheral unit 202B receives the control command, the peripheral unit 202B performs a predetermined process corresponding to the control command (S1581).

  After that, when the main control board 310 randomly selects the history data of the history data and the individual identification value (S1503), the main control board 310 generates authentication information 1020 having the history data as authentication data to generate an intermediate portion of the peripheral board 310. It is transmitted to 202A (S1504). On the other hand, the intermediate unit 202A of the peripheral board 330 performs authentication based on the continuity of communication of the control command with the main control board 310 because the authentication data of the received authentication information 1020 matches the intermediate history data (S1553). ). 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 (S1554).

  When the main control board 310 transmits the next control command to the intermediate section 202A of the peripheral board 330, the main control board 310 stores the control command in the data storage section 311 (S1505). Then, the main control board 310 generates history data based on the transmitted control command and the first history generation method and stores it in the data storage unit 311 (S1506). On the other hand, when receiving the control command, the intermediate unit 202A of the peripheral board 330 stores the received control command in the intermediate storage unit 332 and transfers the control command to the peripheral unit 202B of the peripheral board 330 (S1555). . Then, similarly to the main control board 310, the intermediate unit 202A generates intermediate history data based on the received control command and the first history generation method, and stores it in the intermediate storage unit 332 (S1556). On the other hand, when the peripheral unit 202B receives the control command, the peripheral unit 202B performs a predetermined process corresponding to the control command (S1582).

  Thereafter, when the main control board 310 randomly selects an individual identification value among the history data and the individual identification value (S1507), the main control board 310 generates authentication information 1020 having the individual identification value as authentication data, and The data is transmitted to the intermediate unit 202A (S1508). Then, the main control board 310 switches the first history generation method to the second history generation method and stores it in the data storage unit 311 (S1509). On the other hand, since the authentication data of the received authentication information 1020 matches the expected value, the intermediate unit 202A of the peripheral board 330 performs authentication based on the individual authentication of the main control board 310 (S1557). 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 (S1558). Then, similarly to the main control board 310, the intermediate unit 202A switches the first history generation method to the second history generation method and stores the first history generation method in the intermediate storage unit 332 (S1559).

  When the main control board 310 transmits the next control command to the intermediate section 202A of the peripheral board 330, the main control board 310 stores the control command in the data storage section 311 (S1510). Then, the main control board 310 generates history data based on the transmitted control command and the second history generation method and stores it in the data storage unit 311 (S1511). On the other hand, when the intermediate part 202A of the peripheral board 330 receives the control command, the intermediate part 202A stores the received data in the intermediate side storage part 332 and transfers the control command to the peripheral part 202B of the peripheral board 330 (S1560). Then, similarly to the main control board 310, the intermediate unit 202A generates intermediate history data based on the received control command and the second history generation method, and stores it in the intermediate storage unit 332 (S1561). On the other hand, when the peripheral unit 202B receives the control command, the peripheral unit 202B performs a predetermined process corresponding to the control command (S1583).

  Since the history data and the intermediate history data thus generated are generated by the switched second history generation method, the history data and the intermediate history data so far are different from the generation method. It is difficult to analyze fraudulently. Thereafter, the same processing is performed.

  According to the pachinko gaming machine 100 described above, since the main control unit 201 generates the individual identification value, it is not necessary to store the individual identification value in the main control unit 201 in advance. An increase in the amount of data stored in advance for authentication of the main control unit 201 in the machine 100 can be suppressed. Even if the data of the main control unit 201 is illegally analyzed, the generated individual identification value is not stored in advance, so that it is possible to contribute to prevention of unauthorized analysis for the authentication of the main control unit 201. Then, the main control unit 201 transmits the authentication information 1020 having either one of the history data indicating the history of the control command or the individual identification value to the intermediate unit 202A, and the history according to the transmission of the authentication information 1020 having the individual identification value Since the history generation method for generating data is switched, history data can be generated by switching the history generation method, making it difficult to analyze the history data generation method, and authentication information. It can be difficult to guess whether 1020 has history data or an individual identification value. Further, since the intermediate unit 202A only has to switch the history generation method of the intermediate history data in the same manner as the main control unit 201 in response to the reception of the authentication information 1020 having the individual identification value, it is easy to synchronize with the main control unit 201, When fraud occurs in the authentication information, the history generation methods do not match, which can contribute to fraud prevention. Since the intermediate unit 202A confirms and authenticates the communication continuity of the control command based on the history data, the intermediate unit 202A can detect unauthorized communication switching due to an unauthorized control command. The command can be prevented from being transmitted to the peripheral unit 202B, which can contribute to prevention of unauthorized communication switching. And since the history generation method is switched, the continuity of the history data to be generated is lost, and even if the control command and the history generation method are analyzed illegally, the control command appearance order and the history data appearance Since it becomes difficult to guess the relevance (correspondence etc.) with the order, it is possible to prevent an unauthorized analyst from using authentication information illegally. Further, since the intermediate unit 202A performs the authentication process for the main control unit 201 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. Further, the main control unit 201 generates an individual identification value between the time when the pachinko gaming machine 100 is activated and the time when the authentication information 1020 is generated and stores it in advance, thereby performing a complicated calculation when generating the authentication information. This is unnecessary, and an increase in processing load on the main control unit 201 can be prevented. In addition, since the intermediate unit 202A manages the history of control commands from the main control unit 201, the peripheral unit 202B does not need to manage the history of control commands. Can be prevented from increasing. Moreover, since the intermediate unit 202A transmits the control command from the main control unit 201 to the peripheral unit 202B as it is, the peripheral unit 202B can perform predetermined processing at the same time as the intermediate unit 202A performs authentication processing. Thus, it is possible to prevent a delay from occurring in the predetermined processing in the peripheral portion 202B. Therefore, the communication continuity of the control command can be confirmed, the analysis of the authentication information 1020 used for authentication can be made difficult, and the processing load on the CPU 241 in the peripheral portion 202B can be reduced.

  In the pachinko gaming machine 100 described above, if the history data and the intermediate history data indicate the history of the control command for a plurality of times, even if the number of transmissions of the authentication information 1020 is reduced, the control command fraud that occurred during that time can be corrected. Since it can be detected, the authentication accuracy can be improved. Then, by setting the history data and the intermediate history data to values obtained by calculating past history data, analysis by an unauthorized analyst can be made even more difficult.

(Other configuration of Example 1)
Next, an example of another configuration of the pachinko gaming machine 100 according to the first embodiment described above will be described. In addition, about the same part as the structure mentioned above, the same code | symbol is attached | subjected and only a different part is demonstrated in detail.

  The main control board 310 includes the above-described data storage unit 311, individual identification value generation unit 312, history data generation unit 313, selection unit 314, authentication information generation unit 315, switching unit 316, main control side transmission unit 317, and FIG. And a counting unit 318 indicated by a broken line inside.

  The counting unit 318 corresponds to the counting unit of the present invention, counts the number of appearances of the authentication information 1020 having the individual identification value, and stores the number of appearances in the data storage unit 311. Then, a switching condition indicating whether the switching unit 316 switches the history generation method based on the number of appearances is stored as part of a program executed by the data storage unit 311 or the main control board 310. Then, the switching unit 316 is configured to switch the history generation method as described above when the number of appearances counted by the counting unit 318 satisfies the switching condition.

  The intermediate section 202A of the peripheral board 330 includes the above-described intermediate receiving section 331, intermediate storage section 332, intermediate history data generating section 333, intermediate authentication result data generating section 334, intermediate transmitting section 335, and intermediate switching section 336. And an intermediate counting unit 337 indicated by a broken line in FIG. Note that the peripheral unit 202B includes the peripheral receiving unit 351 and the processing unit 352 described above, and a description thereof will be omitted.

  The intermediate counting unit 337 corresponds to the intermediate counting unit of the present invention, counts the number of receptions of the authentication information 1020 having the individual identification value from the main control board 310, and stores the number of receptions in the intermediate storage unit 332. To do. And the switching condition of whether the intermediate | middle side counting part 337 switches a log | history production | generation system based on the frequency | count of reception is memorize | stored as a part of program which the intermediate | middle side memory | storage part 332 and the intermediate part 202A run. This switching condition is the same switching condition as that of the main control board 310. The intermediate side switching unit 336 is configured to switch the history generation method as described above when the number of receptions counted by the intermediate side counting unit 337 satisfies the switching condition.

  That is, the number of appearances of the counting unit 318 is the number of authentication information 1020 having an individual identification value transmitted from the main control board 310 to the peripheral board 330, and the number of receptions of the intermediate counter 337 is controlled by the peripheral board 330. This is the number of authentication information 1020 having the individual identification value received from the board 310. Therefore, the number of appearances counted by the counting unit 318 and the number of receptions counted by the intermediate side counting unit 337 are the same unless the unauthorized authentication information is generated. Therefore, the switching unit 316 and the intermediate side switching unit By using a common switching condition 336, the switching of the history generation method can be synchronized.

(Other processing related to transmission / reception of authentication information signal)
Hereinafter, a communication example of the authentication information signal performed between the main control unit 201 and the intermediate unit 202A in the configuration described above will be described. First, an example of another transmission procedure of the authentication information signal by the CPU 211 (first computer) of the main control unit 201 will be described with reference to the flowchart of FIG. Since the basic processing of the flowchart shown in FIG. 18 is the same as the flowchart shown in FIG. 14 described above, only different parts will be described.

  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. 18, and when the processing of steps S1200 to S1207 ends, the main control unit 201 proceeds to step S1221. In step S1222, the number of appearances of the individual identification value that has appeared is counted and stored in the data storage unit 311. Then, in step S1222, it is determined whether the counted number of appearances satisfies the switching condition. Note that the number of appearances is premised on being cleared by an initial process (not shown) of the process on the authenticated side. When the main control unit 201 determines that the number of appearances does not satisfy the switching condition (S1222: No), the main control unit 201 proceeds to the process of step S1209 described above. On the other hand, when the main control unit 201 determines that the number of appearances satisfies the switching condition (S1222: Yes), the main control unit 201 selects one of a plurality of predetermined history generation methods in the same manner as the process of step S1208 described above. The two history generation methods are switched by the switching method, the history generation method data in the data storage unit 311 is updated so as to be the switched history generation method, and then the process proceeds to step S1209 described above. Thereafter, the processes of steps S1209 to S1211 described above are executed.

  In the present embodiment, the case where the number of appearances is continuously incremented and the switching condition is set to a multiple of 3, a multiple of 5, etc. will be described, but instead, the number of appearances every time the history generation method is switched. It can also be set as the Example which clears. Further, when the switching condition is set to an irregular number of times such as 3, 7, 11,..., For example, the switching timing of the history generation method can be further complicated.

  Next, a procedure of another reception process of the authentication information signal by the CPU 231 (second computer) of the intermediate unit 202A will be described with reference to the flowchart of FIG. Since the basic processing of the flowchart shown in FIG. 19 is the same as the flowchart shown in FIG. 15 described above, only different parts will be described.

  When executing the authentication side processing shown in FIG. 19, the intermediate unit 202 </ b> A ends the processing of steps S <b> 1301 to S <b> 1309, and counts the number of received individual identification values received in step S <b> 1321 and stores it in the intermediate storage unit 332. Thereafter, in step S1322, it is determined whether or not the counted number of receptions satisfies the switching condition. The number of receptions is premised on being cleared by an initial process (not shown) of the authentication process. If the intermediate unit 202A determines that the number of receptions does not satisfy the switching condition (S1322: No), the intermediate unit 202A proceeds to the process of step S1312 described above. On the other hand, when it is determined that the number of receptions satisfies the switching condition (S1322: Yes), the intermediate unit 202A generates one history from a plurality of predetermined history generation methods as in step S1310 described above. The method is switched by the switching method, the history generation method data in the intermediate storage unit 332 is updated so as to become the switched history generation method, and then the process proceeds to step S1312 described above. Thereafter, the processing of steps S1311 to S1313 described above is executed.

  Note that the processing shown in FIG. 16 of the first embodiment can be used as it is for the procedure of the reception processing of the control signal and the intermediate authentication result signal performed by the CPU 241 (third computer) of the peripheral portion 202B in the peripheral substrate 330. Detailed description will be omitted.

  Next, an example of the operation of the pachinko gaming machine 100 configured as described above will be described. First, in response to activation of the pachinko gaming machine 100 or the like, the main control board 310 generates an individual identification value and stores it in the data storage unit 311 or the like. The main control board 310 does not immediately switch the history generation method even if the authentication information 1020 having the individual identification value is generated. Thereafter, the main control board 310 counts the number of appearances each time the authentication information 1020 having the individual identification value appears, and switches the history generation method when the number of appearances satisfies the switching condition. On the other hand, even if the intermediate portion 202A of the peripheral board 330 receives the authentication information 1020 having the individual identification value, the history generation method is not immediately switched. Thereafter, the peripheral board 330 counts the number of times of receiving the authentication information 1020 having the individual identification value, and switches the history generation method when the number of times of reception satisfies the switching condition.

  According to the pachinko gaming machine 100 described above, since the main control unit 201 generates the individual identification value, it is not necessary to store the individual identification value in the main control unit 201 in advance. An increase in the amount of data stored in advance for authentication of the main control unit 201 in the machine 100 can be suppressed. Even if the data of the main control unit 201 is illegally analyzed, the generated individual identification value is not stored in advance, so that it is possible to contribute to prevention of unauthorized analysis for the authentication of the main control unit 201. Then, the main control unit 201 transmits the authentication information 1020 having either one of the history data indicating the history of the control command or the individual identification value to the intermediate unit 202A, and the history according to the transmission of the authentication information 1020 having the individual identification value Since the history generation method for generating data is switched, history data can be generated by switching the history generation method, making it difficult to analyze the history data generation method, and authentication information. It can be difficult to guess whether 1020 has history data or an individual identification value. Further, since the intermediate unit 202A only has to switch the history generation method of the intermediate history data in the same manner as the main control unit 201 in response to the reception of the authentication information 1020 having the individual identification value, it is easy to synchronize with the main control unit 201, When fraud occurs in the authentication information, the history generation methods do not match, which can contribute to fraud prevention. Since the intermediate unit 202A confirms and authenticates the communication continuity of the control command based on the history data, the intermediate unit 202A can detect unauthorized communication switching due to an unauthorized control command. The command can be prevented from being transmitted to the peripheral unit 202B, which can contribute to prevention of unauthorized communication switching. And since the history generation method is switched, the continuity of the history data to be generated is lost, and even if the control command and the history generation method are analyzed illegally, the control command appearance order and the history data appearance Since it becomes difficult to guess the relevance (correspondence etc.) with the order, it is possible to prevent an unauthorized analyst from using authentication information illegally. Further, since the intermediate unit 202A performs the authentication process for the main control unit 201 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. Further, the main control unit 201 generates an individual identification value between the time when the pachinko gaming machine 100 is activated and the time when the authentication information 1020 is generated and stores it in advance, thereby performing a complicated calculation when generating the authentication information. This is unnecessary, and an increase in processing load on the main control unit 201 can be prevented. In addition, since the intermediate unit 202A manages the history of control commands from the main control unit 201, the peripheral unit 202B does not need to manage the history of control commands. Can be prevented from increasing. Moreover, since the intermediate unit 202A transmits the control command from the main control unit 201 to the peripheral unit 202B as it is, the peripheral unit 202B can perform predetermined processing at the same time as the intermediate unit 202A performs authentication processing. Thus, it is possible to prevent a delay from occurring in the predetermined processing in the peripheral portion 202B. Therefore, the communication continuity of the control command can be confirmed, the analysis of the authentication information 1020 used for authentication can be made difficult, and the processing load on the CPU 241 in the peripheral portion 202B can be reduced.

  In the pachinko gaming machine 100 described above, the intermediate section 202A of the main control board 310 and the peripheral board 330 counts the number of appearance and reception of individual identification values, and switches the history generation method when the number satisfies the switching condition. Since the switching is performed by the method, the continuity of the generated history data and the switching timing of the history generation method can be further complicated, so that unauthorized analysis can be made more difficult.

  Further, in the pachinko gaming machine 100 described above, if the history data and the intermediate history data indicate the history of the control command for a plurality of times, even if the number of times the authentication information 1020 is transmitted is reduced, Since fraud can be detected, the authentication accuracy can be improved. Then, by setting the history data and the intermediate history data to values obtained by calculating past history data, analysis by an unauthorized analyst can be made even more difficult.

  Next, in the pachinko gaming machine 100 according to the first embodiment, when a plurality of different individual identification values are used, switching information for switching a plurality of history generation methods can be associated with each of the plurality of individual identification values. .

  For example, as shown in FIG. 20, the main control board 310 stores switching information H1 in association with the individual identification value C1 and switching information H2 in association with the individual identification value C2 in the data storage unit 311. The switching information H1 and H2 are set, for example, as “history generation method D1” and “history generation method D2,” “shift one”, “shift three”, and the like for a table indicating a plurality of history generation methods. The selection unit 314 described above randomly selects one of the three options of the history data, the individual identification value C1, and the individual identification value C2. The switching unit 316 described above selects the history generation method based on the switching information H1 when the selection unit 314 selects the individual identification value C1, and based on the switching information H2 when the selection unit 314 selects the individual identification value C2. Switch. Further, the intermediate section 202A of the peripheral board 330 stores the switching information H1 and H2 in association with the expected values B1 and B2 that match the individual identification values C1 and C2 of the main control board 310, and stores them in the intermediate storage section 332. To do. Then, the intermediate side switching unit 336 described above switches the switching information H1 when the intermediate authentication result data generation unit 334 establishes the authentication by matching the individual identification value C1 and the expected value B1, and the intermediate authentication result data generation unit 334. If the authentication is established by matching the individual identification value C2 with the expected value B2, the history generation method is switched based on the switching information H2.

  As described above, even if the pachinko gaming machine 100 is configured, the history generation method can be switched according to the appearance and reception of the individual identification value, so that the same operational effects as those of the first embodiment can be obtained. Further, the switching information H1 and H2 are associated with the plurality of individual identification values of the main control unit 201 and the plurality of expected values of the intermediate unit 202A, and the history generation method is switched based on the switching information H1 and H2. As a result, the continuity of the generated history data and the switching timing of the history generation method can be further complicated, so that unauthorized analysis can be made more difficult. In addition, since it is difficult to estimate whether the authentication information 1020 has history data or an individual identification value, unauthorized use of the authentication information can be prevented.

[Example 2]
Hereinafter, a second embodiment of the pachinko gaming machine 100 described above will be described. In addition, about the same part as the structure of Example 1 mentioned above, the same code | symbol is attached | subjected and only a different part is demonstrated in detail.

(Functional configuration of main control board and peripheral board)
First, the pachinko gaming machine 100 includes the control unit 200 shown in FIG. The control unit 200 includes a main control unit 201, an intermediate unit 202A, an effect control unit 202B, and a prize ball control unit 203. As shown in FIG. 21, the pachinko gaming machine 100 includes a main control board 310 having a function as the main control unit 201, and a peripheral board 330 having the intermediate unit 202A and the effect control unit (peripheral unit) 202B described above. , And is configured. The main control board 310 is electrically connected so as to communicate with the intermediate portion 202A of the peripheral board 330.

  The main control board 310 includes the data storage unit 311, the individual identification value generation unit 312, the history data generation unit 313, the switching unit 316, the main control side transmission unit 317, the first authentication information generation unit 315a, and the second authentication. An information generation unit 315b and a determination unit 319 are included.

  The first authentication information generation unit 315a corresponds to a first authentication information generation unit of the present invention, and the authentication information 1020 used by the intermediate unit 202A of the peripheral board 330 for authentication of the main control board (main control part) 310 is The history data generated by the history data generation unit 313 is generated so as to have authentication data. That is, the first authentication information generation unit 315a generates the authentication information 1020 of the data type K1 shown in FIG.

  The second authentication information generation unit 315b corresponds to a second authentication information generation unit of the present invention. When the determination unit 319 described later determines to switch, the second authentication information generation unit 315b is generated by the individual identification value generation unit 312 and is stored in the data storage unit (individual The authentication information 1020 is generated so as to have the individual identification value stored in the identification value storage means) 311 as the authentication data. That is, the second authentication information generation unit 315b generates the authentication information 1020 of the data type K2 shown in FIG.

  Note that the first authentication information generation unit 315a and the second authentication information generation unit 315b may be configured as separate bodies, or may be configured as a single unit like the authentication information generation unit 315 described above.

  The determination unit 319 corresponds to the determination unit of the present invention, and randomly determines whether or not to switch the history generation method of the history data generation unit 313. The determination unit 319 randomly determines whether or not to switch so that the probability of occurrence of switching, that is, the probability of generating (generating) authentication information having an individual identification value has a predetermined frequency, using a random number or the like. That is, since the determination unit 319 can adjust the appearance frequency of the individual identification value, the individual identification value can be irregularly inserted into a plurality of history data. The guess of the distinction can be made difficult. Then, the switching unit 316 determines the history generation method of the history data generation unit (history data generation unit) 312 from among a plurality of predetermined history generation methods in response to the determination by the determination unit 319 to switch. Switching is performed by a predetermined switching method, and the history generation method data in the data storage unit 311 is set. For example, the switching unit 316 may switch between two types of history generation methods, or may switch a plurality of history generation methods in order.

  The main control side transmission unit 317 includes authentication information 1020 having history data generated by the first authentication information generation unit 315a, authentication information 1020 having a solid identification value generated by the second authentication information generation unit 315b, and a peripheral board. Each of a plurality of control commands for controlling the peripheral portion 202B of 330 is transmitted to the intermediate portion 202A of the peripheral substrate 330. Then, the main control side transmission unit 317 transmits each authentication information 1020 to the intermediate unit 202A of the peripheral board 330 as the authentication information signal.

  Subsequently, as in the first embodiment, the intermediate unit 202A of the peripheral board 330 includes an intermediate reception unit 331, an intermediate storage unit 332, an intermediate history data generation unit 333, an intermediate authentication result data generation unit 334, and an intermediate transmission. A part 335 and an intermediate side switching part 336. The peripheral portion 202B also includes the peripheral-side receiving unit 351 and the processing unit 352 described above as in the first embodiment. As described above, the peripheral substrate 330 can be realized by the same configuration as that of the first embodiment, and thus the description thereof is omitted.

  Since the pachinko gaming machine 100 configured as described above generates the individual identification value by the main control board 310 after starting the pachinko gaming machine 100, the individual identification value for the main control board 310 to identify the individual is previously set. There is no need to memorize and illegal analysis can be made difficult. Also, authentication information in which either one of history data or individual identification value is set is transmitted from the main control board 310 to the intermediate part 202A of the peripheral board 330, and the intermediate part 202A of the peripheral board 330 is added to the history data of the authentication information. Based on this, a configuration is employed in which authentication is performed based on the continuity of communication of control commands, and authentication is performed based on the individual identification of the main control board 310 based on the individual identification value of the authentication information. When the main control board 310 decides to switch randomly, the history generation system is switched by the switching system and authentication information having a solid identification value is transmitted to the peripheral board 330, and The unit 202A can switch the history data of the authentication information irregularly because the history generation method is switched by the same switching method in response to the reception of the authentication information having the individual identification value. It is possible to make unauthorized analysis of Further, the pachinko gaming machine 100 generates authentication information having history data when the main control board 310 is normal and transmits it to the intermediate portion 202A of the peripheral board 330, and the main control board 310 has an individual identification value. Since the authentication information is generated and transmitted to the intermediate portion 202A of the peripheral board 330, the history data can be accidentally mixed into a plurality of history data, making it difficult to illegally analyze the history data. can do. Therefore, even if the authentication information is independently transmitted from the main control unit 201 to the intermediate part 202A of the peripheral board 330, it can be difficult to easily analyze it.

  In the present embodiment, the CPU 211 of the main control board 310 is the first computer in the claims, and the CPU 231 of the intermediate section 202A of the peripheral board 330 is the second computer of the claims, and the CPU 241 of the effect control section 202B of the peripheral board 330. Will be described as functioning as the third computer in the claims. The ROM 212 of the main control board 310 includes an individual identification value generation unit, a history data generation unit, a first authentication information generation unit, a second authentication information generation unit, a switching unit, and a main control side. A main control side authentication program for functioning as various means such as transmission means, determination means, and the like 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, intermediate authentication result data generating means, intermediate transmitting means, and intermediate switching means. The intermediate side authentication program for functioning as various means such as. Further, the ROM 242 of the peripheral portion 202B of the peripheral board 330 stores a peripheral side authentication program for causing the third computer to function as various means such as peripheral side receiving means and processing means in the claims. 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.

(Processing 2 concerning transmission / reception of authentication information signal)
Hereinafter, communication example 2 of the authentication information signal performed between the main control unit 201 and the intermediate unit 202A of the peripheral board 330 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.

  When the pachinko gaming machine 100 is turned on (turned on), the main control unit 201 executes the authenticated side processing shown in FIG. 22, and in step S1600, the individual identification as shown in the individual identification value generation unit 312 is performed. A value is generated and stored in the data storage unit 311 and then the process proceeds to step S1601. When the main control unit 201 uses a plurality of individual identification values and generates a part of them, a part of individual identification values are generated, and the remaining individual identification values that are not generated do not generate a predetermined value. The individual identification value.

  In step S1601, the main control unit 201 determines whether a control command has been generated based on the control command stored in the data storage unit 311. When the main control unit 201 determines that a control command has not been generated (S1601: No), the main control unit 201 proceeds to the process of step S1603. On the other hand, if the main control unit 201 determines that a control command is generated (S1601: Yes), in step S1602, the history generation method data in the data storage unit 311 and the control command that is generated by the history generation method. Based on the data, history data is generated and stored in the data storage unit 311, and then the process proceeds to step S 1603.

  In step S1603, the main control unit 201 determines whether it is a predetermined authentication timing. When the main control unit 201 determines that it is not the authentication timing (S1603: No), the main control unit 201 proceeds to the process of step S1611. On the other hand, when the main control unit 201 determines that it is the authentication timing (S1603: Yes), the process proceeds to step S1604.

  In step S1604, the main control unit 201 determines whether to switch the history generation method based on a random number or the like, stores the determination result in the RAM 213, etc., and then proceeds to the processing of step S1605. In step S1605, the main control unit 201 determines whether or not to switch is determined based on the determination result. If the main control unit 201 determines that it has not been switched (S1605: No), authentication information in which authentication command C is set in the identification unit 1021 and history data as authentication data is set in the data unit 1022 in step S1606. (History data) 1020 is generated and stored in the data storage unit 311, and then the process proceeds to step S1609.

  On the other hand, when the main control unit 201 determines that it is determined to switch (S1605: Yes), in step S1607, the identification command 102 is set in the identification unit 1021, and the individual identification value as authentication data is set in the data unit 1022. Authentication information (individual identification value) 1020 is generated and stored in the data storage unit 311, and then the process proceeds to step S 1608. In step S1608, the main control unit 201 switches one history generation method from a plurality of predetermined history generation methods using the switching method, and the data storage unit 311 so that the switched history generation method is obtained. The history generation method data is updated, and then the process proceeds to step S1609.

  In step S1609, the main control unit 201 encrypts the authentication information 1020 generated this time with a predetermined encryption method with the intermediate unit 202A of the peripheral board 330, and in step S1610, the encrypted authentication information 1020 is encrypted. An authentication information signal is generated based on the information 1020 and transmitted from the transmission unit 316 to the intermediate unit 202A, and then the process proceeds to step S1611. If encryption is not required between the main control unit 201 and the intermediate unit 202A, the processing in step S1609 is deleted, and the authentication information 1020 is transmitted to the intermediate unit 202A as it is.

  In step S <b> 1611, the main control unit 201 determines whether or not the pachinko gaming machine 100 is turned off. If the main control unit 201 determines that the power is not turned off (S1611: No), the main control unit 201 returns to the process of step S1601 and repeats a series of processes. On the other hand, when the main control unit 201 determines that the power is turned off (S1611: Yes), the process according to this flowchart ends.

  Subsequently, the authentication information signal reception processing procedure performed by the CPU 231 (second computer) of the intermediate unit 202A on the peripheral board 330, and the control signal and the intermediate authentication performed by the CPU 241 (third computer) of the peripheral unit 202B. As the result signal reception processing procedure, the authentication-side processing shown in FIG. 15 and the processing shown in FIG.

(History generation method switching procedure example 2)
Next, in the pachinko gaming machine 100, an example of a procedure when the intermediate part 202A of the main control board 310 and the peripheral board 330 sequentially switches between the first history generation method and the second history generation method will be described with reference to the drawing of FIG. I will explain.

  In FIG. 23, the main control board 310 as the person to be authenticated generates an individual identification value in response to the activation of the pachinko gaming machine 100 and the like, and stores the generated individual identification value in the data storage unit 311 (S1700). Thereafter, when the main control board 310 transmits a control command to the intermediate section 202A of the peripheral board 330 according to the operation of the pachinko gaming machine 100, the main control board 310 stores the control command in the data storage section 311 (S1701). Then, the main control board 310 generates history data based on the transmitted control command and the first history generation method and stores it in the data storage unit 311 (S1702). On the other hand, when receiving the control command, the intermediate section 202A of the peripheral board 330 stores the received data in the intermediate storage section 332 and transfers the control command to the peripheral section 202B of the peripheral board 330 (S1751). Then, similarly to the main control board 310, the intermediate unit 202A generates intermediate history data based on the received control command and the first history generation method, and stores it in the intermediate storage unit 332 (S1752). On the other hand, when the peripheral unit 202B receives the control command, the peripheral unit 202B performs a predetermined process corresponding to the control command (S1781).

  Thereafter, when the main control board 310 randomly determines not to switch the history generation method (S1703), it generates authentication information 1020 having history data associated in advance as authentication data without switching the history generation method. To the intermediate portion 202A of the peripheral board 310 (S1704). On the other hand, the intermediate unit 202A of the peripheral board 330 performs authentication based on the continuity of communication of the control command with the main control board 310 since the authentication data of the received authentication information 1020 matches the intermediate history data (S1753). ). 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 (S1754).

  When the main control board 310 transmits the next control command to the intermediate section 202A of the peripheral board 330, the main control board 310 stores the control command in the data storage section 311 (S1705). Then, the main control board 310 generates history data based on the transmitted control command and the first history generation method and stores it in the data storage unit 311 (S1706). On the other hand, when receiving the control command, the intermediate unit 202A of the peripheral board 330 stores the received control command in the intermediate storage unit 332 and transfers the control command to the peripheral unit 202B of the peripheral board 330 (S1755). . Then, similar to the main control board 310, the intermediate unit 202A generates intermediate history data based on the received control command and the first history generation method, and stores it in the intermediate storage unit 332 (S1756). On the other hand, when the peripheral unit 202B receives the control command, the peripheral unit 202B performs a predetermined process corresponding to the control command (S1782).

  After that, when switching the history generation method, the main control board 310 determines at random (S1707), and generates authentication information 1020 having an individual identification value associated in advance as the authentication data for switching the history generation method. It transmits to the intermediate part 202A of the peripheral board 310 (S1708). Then, the main control board 310 switches the first history generation method to the second history generation method and stores it in the data storage unit 311 (S1709). On the other hand, since the authentication data of the received authentication information 1020 matches the expected value, the intermediate unit 202A of the peripheral board 330 performs authentication based on the individual authentication of the main control board 310 (S1757). 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 (S1758). Then, similar to the main control board 310, the intermediate unit 202A switches the first history generation method to the second history generation method and stores the first history generation method in the intermediate storage unit 332 (S1759).

  When the main control board 310 transmits the next control command to the intermediate section 202A of the peripheral board 330, the main control board 310 stores the control command in the data storage section 311 (S1710). Then, the main control board 310 generates history data based on the transmitted control command and the second history generation method and stores it in the data storage unit 311 (S1711). On the other hand, when receiving the control command, the intermediate unit 202A of the peripheral board 330 stores the received data in the intermediate storage unit 332 and transfers the control command to the peripheral part 202B of the peripheral board 330 (S1760). Then, similarly to the main control board 310, the intermediate unit 202A generates intermediate history data based on the received control command and the second history generation method, and stores it in the intermediate storage unit 332 (S1761). On the other hand, when the peripheral unit 202B receives the control command, the peripheral unit 202B performs a predetermined process corresponding to the control command (S1783).

  Since the history data and the intermediate history data generated in this way are generated by the switched second history generation method, the history data and the peripheral history data so far are different from the generation method. It is difficult to analyze fraudulently. Thereafter, the same processing is performed.

  According to the pachinko gaming machine 100 described above, the main control unit 201 generates an individual identification value in the same manner as in the first embodiment, and thus the individual identification value is stored in the main control unit 201 in advance. Since it becomes unnecessary, an increase in the amount of data stored in advance for authentication of the main control unit 201 in the pachinko gaming machine 100 can be suppressed. Even if the data of the main control unit 201 is illegally analyzed, the generated individual identification value is not stored in advance, so that it is possible to contribute to prevention of unauthorized analysis for the authentication of the main control unit 201. Then, the main control unit 201 transmits the authentication information 1020 having either one of the history data indicating the history of the control command or the individual identification value to the intermediate unit 202A, and the history according to the transmission of the authentication information 1020 having the individual identification value Since the history generation method for generating data is switched, history data can be generated by switching the history generation method, making it difficult to analyze the history data generation method, and authentication information. It can be difficult to guess whether 1020 has history data or an individual identification value. Further, since the intermediate unit 202A only has to switch the history generation method of the intermediate history data in the same manner as the main control unit 201 in response to the reception of the authentication information 1020 having the individual identification value, it is easy to synchronize with the main control unit 201, When fraud occurs in the authentication information, the history generation methods do not match, which can contribute to fraud prevention. Since the intermediate unit 202A confirms and authenticates the communication continuity of the control command based on the history data, the intermediate unit 202A can detect unauthorized communication switching due to an unauthorized control command. The command can be prevented from being transmitted to the peripheral unit 202B, which can contribute to prevention of unauthorized communication switching. And since the history generation method is switched, the continuity of the history data to be generated is lost, and even if the control command and the history generation method are analyzed illegally, the control command appearance order and the history data appearance Since it becomes difficult to guess the relevance (correspondence etc.) with the order, it is possible to prevent an unauthorized analyst from using authentication information illegally. Further, since the intermediate unit 202A performs the authentication process for the main control unit 201 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. Further, the main control unit 201 generates an individual identification value between the time when the pachinko gaming machine 100 is activated and the time when the authentication information 1020 is generated and stores it in advance, thereby performing a complicated calculation when generating the authentication information. This is unnecessary, and an increase in processing load on the main control unit 201 can be prevented. In addition, since the intermediate unit 202A manages the history of control commands from the main control unit 201, the peripheral unit 202B does not need to manage the history of control commands. Can be prevented from increasing. Moreover, since the intermediate unit 202A transmits the control command from the main control unit 201 to the peripheral unit 202B as it is, the peripheral unit 202B can perform predetermined processing at the same time as the intermediate unit 202A performs authentication processing. Thus, it is possible to prevent a delay from occurring in the predetermined processing in the peripheral portion 202B. Therefore, the communication continuity of the control command can be confirmed, the analysis of the authentication information 1020 used for authentication can be made difficult, and the processing load on the CPU 241 in the peripheral portion 202B can be reduced.

  In the pachinko gaming machine 100 described above, if the history data and the intermediate history data indicate the history of control commands for a plurality of times, even if the number of times of transmission of multiple types of authentication information is reduced, Since fraud can be detected, the authentication accuracy can be improved. Then, by setting the history data and the intermediate history data to values obtained by calculating past history data, analysis by an unauthorized analyst can be made even more difficult.

  In this embodiment, a case where the first authentication information generation unit 315a generates authentication information 1020 having history data in response to the determination that the determination unit 319 of the main control board 310 does not switch the history generation method will be described. did. Instead of this, after the first authentication information generation unit 315a generates the authentication information 1020 having history data, the determination unit 319 may determine whether to switch the history generation method at a predetermined timing. it can. That is, the main control board 310 normally generates authentication information 1020 having history data, and generates authentication information 1020 having an individual identification value when the determination unit 319 determines to switch. With such a configuration, it is possible to reduce the communication frequency of the individual identification value and increase the communication frequency of the history data.

  Note that the method for controlling the main control unit and the peripheral units 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 a gaming machine in which fraud to the main control unit is concerned and a control board mounted on the gaming machine, 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.
