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. There is also a problem peculiar to gaming machines that the processing load on the main control unit cannot be increased due to the authentication process.

  In order to eliminate the above-described problems caused by the conventional technology, the present invention minimizes the processing load on the main control unit, makes it possible to perform authentication based on communication continuity of control commands, and makes it difficult to analyze authentication information used for authentication. It is an object of the present invention to provide a gaming machine and a gaming machine authentication method that can be performed.

The individual identification value generating step generates the plurality of types of individual identification values based on the stored data after the gaming machine is activated .

According to the gaming machine authentication method of the present invention described in claim 7, the main control unit, for example, at least of the plurality of types of individual identification values in response to the activation of the gaming machine and detection of a predetermined timing. One is generated based on predetermined storage data of the main control unit, and is stored as a plurality of types of individual identification values in the individual identification value storage means. When the main control unit transmits a control command to the peripheral unit according to the operation of the gaming machine, the main control unit generates history data indicating the history by the history generation method. When the main control unit randomly selects one individual identification value from a plurality of types of individual identification values, it generates authentication information by adding the individual identification value to the history data by a predetermined addition method. It can be transmitted to the peripheral part. On the other hand, the expected value storage means in the peripheral portion stores in advance a plurality of types of expected values that match each of a plurality of types of individual identification values to be stored by the main control unit. When the peripheral unit receives the control command from the main control unit, the peripheral unit performs predetermined processing corresponding to the control command, and transmits peripheral side history data indicating the history of the control command received from the main control unit to the main control unit. It is generated by the same history generation method. When the peripheral unit receives the authentication information from the main control unit, the peripheral unit extracts a plurality of pieces of authentication history data from the received authentication information based on each of a plurality of types of expected values and the same additional method as the main control unit. The peripheral unit can authenticate the main control unit based on the determination result of whether or not there is a match with the peripheral history data among the plurality of extracted authentication history data. Further, when the main control unit detects the generation or transmission of a predetermined detection target control command, the main control unit switches the history generation method by a predetermined history switching method. Thereafter, when the main control unit transmits a control command to the peripheral unit according to the operation of the gaming machine, the main control unit can generate history data indicating the history by the switched history generation method. On the other hand, when the peripheral unit detects reception of a predetermined detection target control command, the peripheral unit switches the history generation method by the same history switching method as that of the main control unit. Thereafter, when the peripheral unit receives a control command from the main control unit, the peripheral unit performs predetermined processing corresponding to the control command, and switches the peripheral side history data indicating the history of the control command received from the main control unit. It can be generated by the same history generation method as the control unit.

  As described above, according to the present invention, the main control unit generates the authentication information with the randomly selected individual identification value added to the history data indicating the history of the control command, and transmits it to the peripheral unit. Therefore, even if the peripheral part uses authentication data history data for authentication of the main control part, the randomly selected individual identification value changes irregularly, so the regularity of the authentication information is lost, and the authentication information is illegal. Prevention of analysis can be expected. In addition, the main control unit only needs to randomly select one individual identification value from a plurality of types of individual identification values and add it to the history data. Therefore, the main control unit increases the code amount of the program stored in the main control unit and the main control unit. An increase in processing load on the control unit can be suppressed. Furthermore, since the main control unit generates at least one of a plurality of types of individual identification values based on the stored data of the main control unit, the generated individual identification value is stored in the main control unit in advance. Therefore, an increase in the amount of data stored in advance for authentication of the main control unit in the gaming machine can be suppressed. Since the main control unit can store a plurality of types of individual identification values in advance before generating authentication information, it is not necessary to perform complicated calculations when generating authentication information. Increase in burden can be prevented. In addition, since the main control unit generates and stores the individual identification value after starting the gaming machine, the individual identification value is stored in the ROM or the like of the main control unit when the gaming machine is not started. Therefore, it is possible to make it difficult to illegally analyze a plurality of types of individual identification values and their generation methods in the main control unit by reverse engineering, disassembly, or the like. Furthermore, if all of the plurality of types of individual identification values are generated, it is not necessary to store all of the plurality of types of individual identification values in the ROM of the main control unit. Can be made even more difficult. Also, when using multiple types of individual identification values in a gaming machine, it is necessary to store each of the multiple types of individual identification values together in a ROM or the like in consideration of the processing capability and processing efficiency of the main control unit. For this reason, there is a possibility that multiple types of individual identification values used for authentication are likely to be illegally analyzed. However, by using the individual identification value generation means as in the present invention, multiple types of individual identification values are illegal. It can be made even more difficult to be analyzed. On the other hand, since the peripheral unit checks and authenticates the communication continuity of the control command based on the history data, it can detect unauthorized communication switching due to an unauthorized control command. It can contribute to prevention. In addition, since the peripheral part extracts the authentication history data from the authentication information using a plurality of types of expected values, the authentication history data and the peripheral side history are added when the regular individual identification value is not added to the history data. Since the data do not match, fraud can be reliably detected. In addition, since the peripheral unit confirms all combinations of each of a plurality of types of expected values and authentication information and authenticates the main control unit, the main control unit simply selects the individual identification value. It is possible to improve and eliminate the need for complicated processing. In addition, since the main control unit generates an individual identification value based on the stored data, if the stored data of the main control unit is altered, the main control unit generates an individual identification value that is different from the expected value of the peripheral part. Therefore, the peripheral part can no longer be authenticated by the main control part, and can contribute to prevention of fraud. In addition, for example, when an illegal board intervenes between the main control unit and the peripheral part, the processing load must be increased because the analysis load on the illegal board increases, so the cost and design difficulty are reduced. By increasing the number, it is possible to contribute to deterring production of illegal substrates. Therefore, the processing load of the main control unit can be minimized, the communication continuity of the control command can be confirmed, and the analysis of authentication information used for authentication can be made difficult.

  In the gaming machine described above, the main control unit generates at least one of a plurality of types of individual identification values based on stored data in response to the activation of the gaming machine. It is not necessary to store the individual identification value to be generated in advance, and authentication of the main control unit can be performed immediately after the start of the gaming machine, which can contribute to improvement of authentication strength of authentication information. In addition, when the main control unit generates an individual identification value that is different from the expected value of the peripheral part, it can be determined that the stored data has been tampered with before activation, which can contribute to fraud prevention.

  In the gaming machine described above, the main control unit and the peripheral unit switch the addition method based on a predetermined switching method in accordance with the detection of the detection target control command. Even if the individual identification value is added, the authentication information to be generated is different, so that unauthorized analysis can be made even more difficult. In addition, since the detection target control command is the switching timing of the additional method, the main control unit and the peripheral unit can be switched synchronously even after the gaming machine is activated.

  In the gaming machine described above, the main control unit and the peripheral unit switch the addition method based on a predetermined switching method in accordance with the detection of the detection target control command, and the history generation method is a predetermined history switching method. Since the addition method for adding the individual identification value to the history data is switched and the history generation method for the history data is also switched, the generated authentication information has no continuity, making unauthorized analysis more It can be made more difficult.

  In the above-described gaming machine, the main control unit and the peripheral unit switch the history generation method based on a predetermined history switching method in response to detection of the detection target control command. Even if the same individual identification value is added, authentication information to be generated is different, so that illegal analysis can be made even more difficult. In addition, since the detection target control command is the switching timing of the additional method, the main control unit and the peripheral unit can be switched synchronously even after the gaming machine is activated.

  In the gaming machine described above, since the history data and the peripheral 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.

For example, the prize ball control unit 203 has various different configurations such as being provided on the same printed circuit board as the main control unit 201 or the effect control unit 202. be able to.

(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 and a transmission unit 316. The main control board 310 is formed of a board different from the peripheral board 330 and is electrically connected so that unidirectional communication with the peripheral board 330 is possible.

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

  The data storage unit 311 has a storage area for storing a plurality of control commands and a plurality of authentication information transmitted to the peripheral unit 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 at the time when it is determined, after being transmitted to the peripheral unit, and the like. In this embodiment, for example, a case where a plurality of types of control commands such as a jackpot reach command, a jackpot start command, a jackpot command, and a jackpot end command are stored in the data storage unit 311 as a history target will be described. Instead, only one predetermined control command can be stored.

  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. Each of the plural types of individual identification values is a value used by the peripheral board 330 (peripheral part) for authentication (individual identification) of the main control board 310 (main control part), and is recorded by the authentication information generation unit 315 described later. The data is added to the data. 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 with an individual identification value as a multiple types of 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 peripheral board 330 can authenticate the individual identification of the main control board 310 by determining whether or not the individual identification value matches the expected value.

  The stored data is unique data of the main control unit 201 stored in advance in the ROM 212 or the like of the main control unit 201. Examples of stored data include program data executed by the CPU 211 of the main control unit 201, predetermined fixed data dedicated for authentication, etc. In this 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, ROM 212, etc., the data storage unit 311, ROM 212, etc. store 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 peripheral portion do not coincide with each other due to the occurrence of data falsification. It can detect and contribute to prevention of tampering.

  The individual identification value generation unit 312 generates an individual identification value at a predetermined generation timing. As an example of the generation timing, when the pachinko gaming machine 100 is activated, when a predetermined control command is generated or when a predetermined number of occurrences is detected, a predetermined time or after the pachinko gaming machine 100 is activated When the time elapses, every time the main control board 310 is authenticated, etc. Note that each time the main control board 310 is authenticated means a timing for generating authentication information to be described later or a timing for transmitting to the peripheral board 330.

  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, it can be implemented by storing in advance a plurality of expected values that match all the individual identification values generated by the plurality of individual identification value generation methods on the peripheral board 330. 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 peripheral board (peripheral part) 330 is set in a predetermined history generation method. Generate with The history data generation unit 313 is, for example, a history generation method at a predetermined generation timing such as an arbitrary timing from the generation (determination) of the control command to the peripheral part of the control command in the pachinko gaming machine 100. History data is generated and stored based on 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 number of retroactive transmission of a single control command, the retroactive range of a plurality of types of control commands, etc. Stipulate. When the history data generating unit 313 generates the history data as a checksum, the history data is a total value obtained by taking a total value of a plurality of single types of control command data or a total of a 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 the transmission unit 316 The authentication information including the history data is discarded without being transmitted. 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 randomly selects one individual identification value from a plurality of types of individual identification values stored in the data storage unit (individual identification value storage unit) 311. . The selection unit 314 randomly selects one individual identification value using a random number or the like and stores it in the RAM 213 or the like. That is, the selection unit 314 selects a plurality of types of individual identification values by switching at random. Therefore, even if a plurality of types of individual authentication values that are fixed values are used, the selected individual identification value can be switched irregularly, making it difficult to illegally analyze the individual identification value used for authentication information. . In addition, the selection unit 314 can adjust the selection frequency by setting a random number or the like, for example, by selecting a predetermined individual identification value only once out of 10 selections.

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

  The transmission unit 316 corresponds to a transmission unit of the present invention, and each of the authentication information generated by the authentication information generation unit 315 and a plurality of types of control commands for controlling the peripheral substrate 330 is transmitted to the peripheral substrate (peripheral portion) 330. Send to. Then, the transmission unit 316 of this embodiment transmits control command data from the main control board 310 to the peripheral board 330 as a control signal. For example, the transmission unit 316 transmits the authentication information to the peripheral board 330 as an authentication information signal that is a signal different from the control signal transmitted from the main control board 310 to the peripheral board 330. 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 functions as peripheral parts such as the effect control unit 202 and the prize ball control unit 203 described above will be described. As shown in FIG. 3, the peripheral board 330 includes a receiving unit 331, a peripheral side storage unit 332, a peripheral side history data generation unit 333, an authentication history data extraction unit 334, and an authentication unit 335.

  The receiving unit 331 corresponds to a receiving unit of the present invention, and receives each of authentication information and control command data (control command) transmitted by the main control board 310. The 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. The receiving unit 331 receives control command data from the main control board 310 by receiving the control signal.

  The peripheral side storage unit 332 corresponds to expected value storage means of the present invention. As the peripheral storage unit 332, for example, a part of the ROM 242 and the RAM 243 (see FIG. 2) of the effect control unit 202 can be used. The peripheral 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 peripheral storage unit 332 matches each of the plurality of types of individual identification values to be received from the main control board 310 described above, that is, the plurality of types of individual identification values to be stored by the data storage unit 311 of the main control board 310. Multiple types of expected values are stored. For example, the expected value is obtained in advance by calculating one or a plurality of individual identification values generated by the individual identification value generation unit 312 of the main control board 310, and is stored in the peripheral side storage unit 332 when the pachinko gaming machine 100 is manufactured. Prestored (written). When the peripheral side storage unit 332 is the RAM 243, a plurality of types of expected values are stored in the ROM 242 and stored from the ROM 242 into the peripheral side storage unit 332 when the pachinko gaming machine 100 is activated.

  Thereby, since the peripheral board 330 matches any one of a plurality of types of expected values if the individual identification value added to the history data of the authentication information is a normal individual identification value, the history data is obtained from the authentication information. The peripheral substrate 330 can be extracted. Further, if the individual identification value of the authentication information is invalid, it does not match any of a plurality of types of expected values, so that the peripheral data 330 cannot be extracted from the authentication information. The peripheral storage unit 332 stores history generation method data and additional method data similar to those of the main control unit 201. The history generation method data indicates a history generation method used by the peripheral side history data generation unit 333, and an initial value is set at the time of startup or the like and stored in the peripheral side storage unit 332. The additional method data indicates the same additional method as that of the main control board 310 used by the authentication history data extraction unit 334.

  The peripheral side history data generation unit 333 corresponds to the peripheral side history data generation means of the present invention, and the peripheral side 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 peripheral history data generation unit 333 receives the same history generation method and peripheral memory as the main control board 310 at a predetermined peripheral 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, peripheral history data is generated and stored. That is, the peripheral 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, if the peripheral side history data receives only the control command data transmitted by the main control board 310, it will match the history data of the main control board 310. It can be determined that data is being received.

  The peripheral history data generation unit 333 according to the present embodiment will be described with respect to the case where the peripheral history data stored in the peripheral storage unit 332 is updated to the generated peripheral history data and stored. In this case, the peripheral side storage unit 332 functions as a peripheral side history data storage unit. Instead of this, for example, the peripheral history data can be stored in the registers of the CPUs 241 and 281, the predetermined storage areas of the RAMs 243 and 283, and the like. In addition, the peripheral history data generating means and its storage means can be realized by dedicated hardware.

  The authentication history data extraction unit 334 corresponds to the authentication history data extraction unit of the present invention, and is received from the main control board 310 based on a plurality of types of expected values and the same additional method as the main control board 310. A plurality of authentication history data is extracted from the authentication information. Specifically, the authentication history data extraction unit 334 deletes each of a plurality of types of expected values from the authentication information by the addition method, extracts a plurality of authentication history data, and stores them in the peripheral storage unit 332. That is, when two expected values are used, the authentication history data extraction unit 334 extracts two authentication history data from which two expected values are deleted from the authentication information, and three expected values. If the value is used, three pieces of authentication history data are extracted. Therefore, since the plurality of authentication history data is a value obtained by deleting each of a plurality of types of expected values from the authentication information (authentication data), if authentic authentication information is received, the plurality of authentication history data One of the authentication history data is history data of the main control board 310.

  The authentication unit 335 corresponds to the authentication unit of the present invention, and the latest peripheral history data stored in the peripheral storage unit 332 among the plurality of authentication history data extracted by the authentication history data extraction unit 334. The main control board (main control unit) 310 is authenticated based on the determination result of whether or not there is a match. If there is a match with the peripheral history data, the authentication unit 335 determines that the received authentication information history data is valid, and thus establishes authentication. In addition, when the authentication unit 335 does not match with the peripheral side history data, for example, it is considered that the history data and the peripheral side history data are different due to fraud, or that invalid authentication information is used. Therefore, since the history data or the individual identification value of the received authentication information can be determined to be invalid, authentication is not established. In other words, the authentication unit 335 authenticates the main control board 310 (main control unit 201) based on communication continuity (history data).

  In this embodiment, a case where the authentication history data extraction unit 334 extracts a plurality of authentication history data and then the authentication unit 335 compares each of the plurality of authentication history data with the peripheral history data is described. However, instead of this, for example, every time the authentication history data extraction unit 334 extracts one authentication history data, the authentication unit 335 may compare with the peripheral history data.

  The peripheral board 330 configured as described above performs a predetermined process in the pachinko gaming machine 100 in accordance with each of a plurality of types of control commands received from the main control board 310. The peripheral board 330 performs the predetermined processing corresponding to the control command indicated by the received control signal when the authentication unit 335 is authenticated, and notifies when the authentication is not established. The predetermined process is a process corresponding to each of a plurality of types of control commands from the main control unit 201 in the pachinko gaming machine 100. For example, an outage process, a jackpot reach process, a jackpot start process, a jackpot round process, Examples include jackpot end processing.

  In the present embodiment, a case where the CPU 211 of the main control board 310 functions as a first computer and each of the CPUs 241 and 281 of the peripheral board 330 functions as a second computer will be described. The ROM 212 of the main control board 310 causes the first computer to function as various means such as individual identification value generation means, history data generation means, selection means, authentication information generation means, and transmission means in the claims. The main control side authentication program is stored. Each of the ROMs 242 and 282 of the peripheral board 330 causes the second computer to function as various means such as receiving means, peripheral history data generating means, authentication history data extracting means, and authenticating means in the claims. The peripheral side authentication program for storing is stored. That is, the authentication program of the present invention is constituted by the main control 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 202 every time a game ball wins the start winning opening 105, and the effect control unit 202 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 202 when the occurrence of the jackpot is determined, and the effect control unit 202 aligns the predetermined symbols and stops the variable display, Control is performed to open the special winning opening 109. The effect control unit 202 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 202 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 202. 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 202 and the prize ball control unit 203, and the process proceeds to step S403. When the power-on command is transmitted by this process, the effect control unit 202 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 202, 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), it transmits a jackpot reach command (symbol variation command) to the effect control unit 202 in step S413. 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, if 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 202, and the process proceeds to step S416.

  In step S416, the main control unit 201 transmits a jackpot start command to the effect control unit 202. 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 202. To do. When the transmission of the jackpot command for all rounds is completed, the main control unit 201 transmits the jackpot end command to the effect control unit 202 in step S418, and proceeds to the process of 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 an outlier reach command (design variation command) to the effect control unit 202, and in step S420. 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 202, and the process proceeds to 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 202, 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 peripheral board 330 stores the control command data as a history in the peripheral side storage unit 332 each time various control commands are received, and updates the peripheral side history data in the peripheral side storage unit 332.

  Next, 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 202 in the pachinko gaming machine 100 is shown in FIG. 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 202 will be described with reference to the flowchart shown in FIG. The effect control unit 202 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 202 repeats this determination process to wait for the symbol variation command to be received. On the other hand, when determining that the symbol variation command has been received (S701: Yes), the effect control unit 202 acquires a random effect selection random number in step S702, and in step S703, based on the acquired random number, The type is selected, and the process proceeds to step S704. In step S704, the effect control unit 202 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 202 determines whether the effect time has elapsed. If the effect control unit 202 determines that the effect time has elapsed (S705: Yes), the effect control unit 202 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 202 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 production | presentation control part 202 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 202 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. End the process.

  Next, the big hitting process by the effect control unit 202 will be described with reference to the flowchart shown in FIG. The effect control unit 202 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 202 repeats this determination process to wait for reception of the jackpot start command. On the other hand, when determining that the jackpot start command has been received (S801: Yes), the effect control unit 202 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 202 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 202 repeats this determination process to wait for reception of the jackpot command. On the other hand, when determining that the jackpot command has been received (S803: Yes), the effect control unit 202 rounds corresponding to the round jackpot commands received by the lamp control unit 251 and 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 202 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 202 repeats this determination process to wait for reception of the jackpot end command. On the other hand, if it is determined that the jackpot end command has been received (S805: Yes), the effect control unit 202 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 202 (during symbol variation) will be described. Then, the lamp control unit 251 determines whether or not an effect start command has been received from the effect control unit 202 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 S <b> 906, the lamp control unit 251 determines whether an effect stop command has been received from the effect control unit 202. 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, a description will be given on the assumption that the main control unit 201 outputs an authentication information signal to the peripheral unit to transmit the authentication information from the main control unit 201 to the peripheral unit.

  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. Thereby, the peripheral part can identify the authentication information 1020 based on the identification part 1021. The authentication command is differentiated from the control command data 1001 by using a command different from the control command of the control command data 1001 described above.

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

  In this embodiment, the case where the authentication information 1020 has a configuration including the identification unit 1021 and the data unit 1022 will be described, but instead, for example, a configuration including only the data unit 1022, the data unit 1022 and other associated units Various configurations such as a configuration having an accompanying data portion in which data is set can be employed.

(Example of additional method)
As an addition method for specifying a method for adding an individual identification value to history data, for example, one operation method among four arithmetic operations, XOR, XNOR, and the like is determined in advance in the pachinko gaming machine 100. When the additional method is determined as “+” of the four arithmetic operations, the main control board 310 sets authentication data obtained by adding the selected individual identification value to the history data in the data portion 1022 and generates authentication information 1020. On the other hand, the peripheral board 330 subtracts each of a plurality of types of expected values from the data set in the data portion 1022 of the received authentication information 1020 to extract a plurality of authentication history data. Since each of the plurality of types of expected values matches the plurality of types of individual identification values, if the peripheral board 330 deletes the expected value, one regular data is included in the extracted plurality of authentication data. Since the history data can be extracted, it should match the peripheral history data.

  When the addition method is determined as “−” of the four arithmetic operations, the main control board 310 sets authentication data obtained by subtracting the selected individual identification value from the history data in the data portion 1022 to generate authentication information 1020. On the other hand, the peripheral board 330 adds a plurality of types of expected values from the data set in the data portion 1022 of the received authentication information 1020 to extract a plurality of authentication history data. Even if implemented in this manner, since the plurality of types of expected values match the plurality of types of individual identification values, if the peripheral board 330 adds the expected values, it will be included in the extracted plurality of authentication data. Since one regular history data has been extracted, it should be consistent with the peripheral history data.

  Therefore, any calculation method may be used as long as the additional method is a calculation method in which the peripheral substrate 330 can perform reverse calculation. In this embodiment, the case where the main control board 310 adds only the individual identification value to the history data will be described, but instead of this, a predetermined additional value between the individual identification value and the peripheral board 330 is used. Different embodiments may be made, such as adding both data (eg, predetermined values).

(Processing for sending and receiving authentication information signals)
Below, the example of communication of the said authentication information signal performed between the main-control part 201 and a peripheral part is demonstrated. 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. 12, and in step S1200, as described in the individual identification value generation unit 312, Alternatively, a plurality of individual identification values are 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 data 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. If 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 S1209. 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 individual identification value from a plurality of types of individual identification values stored in the data storage unit 311 based on random numbers, extraction software, and the like. Are stored in the RAM 213 and the like, and then the process proceeds to step S1205. In step S1205, the main control unit 201 generates authentication data (composite value) in which the selected individual identification value is added to the latest history data stored in the data storage unit 311 by the addition method. Thereafter, the process proceeds to step S1206.

  In step S1206, the main control unit 201 generates authentication information 1020 in which the authentication command C is set in the identification unit 1021 and the authentication data is set in the data unit 1022, and stores the authentication information 1020 in the data storage unit 311. Thereafter, the process proceeds to step S1207. . In step S1207, the main control unit 201 encrypts the authentication information 1020 generated this time with a predetermined encryption method with the peripheral unit. In step S1208, the main control unit 201 stores the encrypted authentication information 1020 in the encrypted authentication information 1020. Based on this, an authentication information signal is generated and transmitted from the transmission unit 316 to the peripheral unit, and then the process proceeds to step S1209. If encryption is not required between the main control unit 201 and the peripheral unit, the processing in step S1207 is deleted, and the authentication information 1020 is transmitted to the peripheral unit as it is.

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

  Next, a procedure of the authentication information signal reception process by the peripheral CPUs 241 and 281 (second computer) will be described with reference to the flowchart of FIG.

  When the peripheral unit executes the authentication-side process shown in FIG. 13, in step S1301, the peripheral unit refers to the peripheral-side storage unit 332 and determines whether a control command is received from the main control unit 201. When it is determined that the peripheral unit has not received the control command (S1301: No), the process proceeds to step S1303. On the other hand, when it is determined that the peripheral unit has received the control command (S1301: Yes), in step S1302, the history generation method data and the history generation method of the peripheral storage unit 332 are the same as the main control unit 201. Based on the control command data to be generated, peripheral history data is generated and stored in the peripheral storage unit 332, and then the process proceeds to step S1303.

  In step S <b> 1303, the peripheral unit determines whether the receiving unit 331 has received authentication information (authentication information signal) 1020 from the main control unit 201. When it is determined that the authentication information 1020 has not been received (S1303: No), the peripheral unit proceeds to the process of step S1310. On the other hand, if it is determined that the authentication information 1020 has been received (S1303: Yes), the peripheral unit proceeds to the process of step S1304.

  In step S1304, the peripheral unit decrypts the received authentication information 1020 using a decryption method corresponding to the encryption method of the main control unit 201, extracts authentication data from the data unit 1022 of the authentication information 1020, and performs the authentication. Each of a plurality of types of expected values is deleted from the data based on the reverse method of the additional method data to extract a plurality of authentication history data, and the extracted plurality of authentication history data is stored in the peripheral storage unit 332. Then, the process proceeds to step S1305. If encryption is not required between the main control unit 201 and the peripheral unit, the decryption process in step S1304 is deleted.

  In step S1305, the peripheral unit compares each of the extracted plurality of authentication history data with the latest peripheral history data stored in the peripheral storage unit 332, and matches the authentication history data with the peripheral history data. The determination result as to whether or not the data exists is stored in the peripheral storage unit 332 and the like, and then the process proceeds to step S1306.

  If the peripheral unit determines in step S1306 that there is matching authentication history data (S1306: Yes), the history data of the main control unit 201 matches the peripheral side history data, and the continuity of communication is Since it is valid, authentication of the main control unit 201 is established in step S1307, and then the process proceeds to step S1310. On the other hand, if it is determined that there is no matching authentication history data (S1306: No), the peripheral portion indicates that the continuity of communication is not valid or is invalid authentication information 1020, and thus step S1308. In step S1309, for example, a notification signal is output from the speaker 262 (see FIG. 2) and the process proceeds to step S1310.

  In step S1310, the peripheral unit determines whether or not the pachinko gaming machine 100 is powered off. If the peripheral portion determines that the power is not turned off (S1310: 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 source is turned off (S1310: Yes), the peripheral unit ends the process according to this flowchart.

(Example of authentication process)
Next, in the pachinko gaming machine 100, an example of authentication when the main control board 310 and the peripheral board 330 use two individual identification values and expected values will be described with reference to the drawing of FIG.

  First, as a precondition, the main control board 310 stores two individual identification values A1 and A2 in the data storage unit 311 in advance, and sets the addition method to “+”. On the other hand, the peripheral board 330 stores two expected values B1 and B2 that coincide with the individual identification values A1 and A2 of the main control board 310 in the peripheral storage unit 332 in advance, and the addition method of the main control board 310 is “ I remember that it is “+”. That is, the peripheral board 330 stores “−”, which is an addition method opposite to the main control board 310.

  In FIG. 14, the main control board 310 that is the person to be authenticated generates individual identification values A1 and A2 in response to the activation of the pachinko gaming machine 100, and the generated individual identification values A1 and A2 are stored in the data storage unit 311. Store (S1400). Thereafter, when the main control board 310 transmits a control command to 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 unit 311 (S1401). Then, the main control board 310 generates history data based on the transmitted control command and the history generation method, and stores it in the data storage unit 311 (S1402). On the other hand, when the peripheral board 330 receives the control command, the peripheral board 330 stores the received control command in the peripheral-side storage unit 332 and performs a predetermined process corresponding to the control command (S1451). Then, similarly to the main control board 310, the peripheral board 330 generates peripheral side history data based on the received control command and history generation method, and stores it in the peripheral side storage unit 332 (S1452).

  Thereafter, when the main control board 310 randomly selects one individual identification value A1 out of the two individual identification values A1 and A2 (S1403), the selected individual identification value A1 is added to the latest history data ( Authentication information 1020 having the added authentication data C1 is generated and transmitted to the peripheral board 330 (S1404). On the other hand, the peripheral substrate 330 subtracts (deletes) each of the plurality of expected values B1 and B2 from the authentication data C1 of the received authentication information 1020 to extract the authentication history data C1-B1 and C1-B2, and the authentication Authentication based on continuity of communication of control commands with the main control board 310 is performed based on whether or not the historical data C1-B1 and C1-B2 match the latest peripheral history data (S1453). As a result, since the authentication information 1020 has the authentication data C1 to which the individual identification value A1 is added, the authentication history data C1-B1 from which the expected value B1 that matches the individual identification value A1 is deleted is the main control. Since it becomes the history data of the board 310, if the authentication information 1020 is valid, the authentication history data C1-B1 matches the peripheral history data.

  When the main control board 310 transmits the next control command to the peripheral board 330, the main control board 310 stores the control command in the data storage unit 311 (S1405). Then, the main control board 310 generates history data based on the transmitted control command and history generation method and stores it in the data storage unit 311 (S1406). On the other hand, when the peripheral board 330 receives the control command, the peripheral board 330 stores the received control command in the peripheral-side storage unit 332 and performs a predetermined process corresponding to the control command (S1454). Then, similarly to the main control board 310, the peripheral board 330 generates peripheral side history data based on the received control command and history generation method, and stores it in the peripheral side storage unit 332 (S1455).

  After that, when the main control board 310 randomly selects one individual identification value A2 from the two individual identification values A1 and A2 (S1407), the selected individual identification value A2 is added to the latest history data ( Authentication information 1020 having the added authentication data C2 is generated and transmitted to the peripheral board 330 (S1408). On the other hand, the peripheral board 330 subtracts (deletes) each of the plurality of expected values B1 and B2 from the authentication data C2 of the received authentication information 1020 to extract the authentication history data C2-B1 and C2-B2, and the authentication Authentication based on continuity of communication of control commands with the main control board 310 is performed based on whether or not the historical data C2-B1 and C2-B2 coincide with the latest peripheral history data (S1456). As a result, since the authentication information 1020 has the authentication data C2 to which the individual identification value A2 is added, the authentication history data C2-B2 from which the expected value B2 that matches the individual identification value A2 is deleted is the main control. Since it becomes the history data of the board 310, if the authentication information 1020 is authentic, the authentication history data C2-B2 matches the peripheral history data.

  When the main control board 310 transmits the next control command to the peripheral board 330, the main control board 310 stores the control command in the data storage unit 311 (S1409). Then, the main control board 310 generates history data based on the transmitted control command and history generation method and stores it in the data storage unit 311 (S1410). On the other hand, when the peripheral board 330 receives the control command, the peripheral board 330 stores the received control command in the peripheral-side storage unit 332 and performs a predetermined process corresponding to the control command (S1457). Then, similarly to the main control board 310, the peripheral board 330 generates peripheral side history data based on the received control command and history generation method and stores it in the peripheral side storage unit 332 (S1458).

  Thereafter, when the main control board 310 randomly selects one individual identification value A2 from the two individual identification values A1 and A2 (S1411), the selected individual identification value A2 is added to the latest history data ( Authentication information 1020 having the added authentication data C3 is generated and transmitted to the peripheral board 330 (S1412). On the other hand, the peripheral substrate 330 subtracts (deletes) each of the plurality of expected values B1 and B2 from the authentication data C3 of the received authentication information 1020 to extract authentication history data C3-B1 and C3-B2, and the authentication Authentication based on continuity of communication of control commands with the main control board 310 is performed based on whether or not the historical data C3-B1 and C3-B2 coincide with the latest peripheral history data (S1459). As a result, since the authentication information 1020 includes authentication data C3 to which the individual identification value A2 is added, the authentication history data C3-B2 from which the expected value B2 that matches the individual identification value A2 is deleted is the main control. Since it becomes the history data of the substrate 310, if the authentication information 1020 is valid, the authentication history data C3-B2 matches the peripheral history data. Thereafter, the same processing is performed.

  According to the pachinko gaming machine 100 described above, the main control board 310 generates authentication information 1020 in which the individual identification value selected at random is added to the history data indicating the history of the control command, and transmits it to the peripheral board 330. Therefore, even if the peripheral board 330 uses the history data of the authentication information 1020 for the authentication of the main control board 310, the randomly selected individual identification value changes irregularly, and thus the regularity of the authentication information 1020. Therefore, it can be expected to prevent unauthorized analysis of the authentication information 1020. Further, the main control board 310 only needs to randomly select one individual identification value from a plurality of types of individual identification values and add it to the history data, so that the amount of code of the program stored in the main control board 310 increases. In addition, an increase in processing load on the main control board 310 can be suppressed. Further, since the main control board 310 generates at least one of a plurality of types of individual identification values based on the stored data of the main control board 310, the generated individual identification values are stored in the main control board 310. Since it is not necessary to store in advance, an increase in the amount of data stored in advance for authentication of the main control board 310 in the pachinko gaming machine 100 can be suppressed. Since the main control board 310 can store a plurality of types of individual identification values in advance before generating the authentication information, it is not necessary to perform a complicated operation when generating the authentication information 1020. An increase in the processing load of 310 can be prevented. On the other hand, since the peripheral board 330 is configured to confirm and authenticate the communication continuity of the control command based on the history data, it can detect unauthorized communication switching due to an unauthorized control command. It can contribute to prevention of switching. In addition, since the peripheral substrate 330 extracts the authentication history data from the authentication information 1020 using a plurality of types of expected values, the authentication history data and the peripheral data are extracted when the regular individual identification value is not added to the history data. Since the side history data does not match, fraud can be reliably detected. Further, since the peripheral board 330 confirms all combinations of each of a plurality of types of expected values and the authentication information 1020 and authenticates the main control board 310, the main control board 310 simply sets the individual identification value. It is only necessary to make a selection, and there is no need to include complicated processing. Further, since the main control board 310 generates the individual identification value based on the stored data, when the stored data of the main control board 310 is altered, the individual control value different from the expected value of the peripheral board 330 is controlled. Since the board 310 is generated, the peripheral board 330 can be prevented from authenticating the main control board 310 and contribute to fraud prevention. Further, for example, when an illegal board or the like intervenes between the main control board 310 and the peripheral board 330, the processing load must be increased because the analysis load on the illegal board increases. Increasing the degree can contribute to deterring the production of illegal substrates. Accordingly, the processing load on the main control board 310 can be minimized, the communication continuity of the control command can be confirmed, and the analysis of the authentication information 1020 used for authentication can be made difficult.

  In the pachinko gaming machine 100 described above, the main control board 310 generates at least one of a plurality of types of individual identification values based on the stored data in response to the activation of the pachinko gaming machine 100. Therefore, it is not necessary to store the generated individual identification value in advance, and the authentication of the main control board 310 can be performed immediately after the pachinko gaming machine 100 is started. It can contribute to improvement. Further, when the main control board 310 generates an individual identification value that is different from the expected value of the peripheral board 330, it can be determined that the stored data has been tampered with before activation, which can contribute to fraud prevention.

  Further, in the pachinko gaming machine 100 described above, if the history data and the peripheral 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 peripheral history data to values obtained by calculating past history data, analysis by an unauthorized analyst can be made even more difficult.

[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)

Generation of a set detection target control command or transmission to the peripheral board 330 is detected. In addition, the control command detection unit 316 can start detection in response to activation of the pachinko gaming machine 100, generation or transmission of the first authentication information 2010, and the like. The detection target control command may be one type of control command among a plurality of types of control commands, or two or more types of control commands.

  The additional method switching unit 317 corresponds to the additional method switching means of the present invention, and the additional method used by the authentication information generating unit 315 is determined in advance according to the detection of the detection target control command of the control command detecting unit 316. Switch by switching method. In the present embodiment, as the switching method, switching information with a plurality of additional methods as a table is stored in the data storage unit 311. An example of the switching information is a table that defines different addition methods D1 and D2 and their order. Then, the additional method switching unit 317 switches the additional method data stored in the data storage unit 311 between the additional methods D1 and D2 based on the switching information in response to detection by the control command detection unit 316. As a result, the authentication information generation unit 315 refers to the additional method data in the data storage unit 311 and generates the authentication information 1020 by adding the individual identification value to the history data by the additional method switched by the additional method switching unit 317. Will do.

  Subsequently, as in the first embodiment, the peripheral board 330 includes a receiving unit 331, a peripheral side storage unit 332, a peripheral side history data generation unit 333, an authentication history data extraction unit 334, an authentication unit 335, and A peripheral-side control command detection unit 336 indicated by a broken line and a peripheral-side addition method switching unit 337 are configured.

  The peripheral side control command detection unit 336 corresponds to the peripheral side control command detection means of the present invention, is determined in advance from a plurality of types of control commands in the pachinko gaming machine 100, and is stored in the peripheral side storage unit 332 in advance. The reception of the detection target control command set in the same detection target control command information as that of the main control board 310 is detected from the main control board 310. Further, the peripheral side control command detection unit 336 can start detection in response to activation of the pachinko gaming machine 100, reception of the first authentication information 2010 from the main control board 310, and the like. In addition, as the main control board 310, the detection target control command may be one type of control command among a plurality of types of control commands, or two or more types of control commands.

  The peripheral side additional method switching unit 337 corresponds to the peripheral side additional method switching means of the present invention, and the additional method used by the history data extraction unit 334 in response to the detection by the peripheral side control command detection unit 336 is the main control. Switching is performed by the same switching method (switching information) as that of the substrate 310. That is, the peripheral board 330 stores the same switching information as that of the main control board 310 in the peripheral storage unit 332 in advance. Then, the peripheral side additional method switching unit 337 is configured to use the additional method used by the authentication history data extraction unit 334 in response to detection of the detection target control command of the peripheral side control command detection unit 336, similarly to the main control board 310. Are switched by a predetermined switching method. As a result, the authentication history data extraction unit 334 refers to the additional method data in the peripheral storage unit 332, so that a plurality of authentication histories can be obtained from the authentication information 1020 by the additional method switched by the peripheral side additional method switching unit 337. Data will be extracted.

  In the present embodiment, a case where the CPU 211 of the main control board 310 functions as a first computer and each of the CPUs 241 and 281 of the peripheral board 330 functions as a second computer will be described. The ROM 212 of the main control board 310 includes an individual identification value generation unit, a history data generation unit, a selection unit, an authentication information generation unit, a transmission unit, a control command detection unit, and an additional method switching unit. The main control side authentication program for functioning as various means such as. In addition, each of the ROMs 242 and 282 of the peripheral board 330 includes the receiving unit, the peripheral side history data generating unit, the authentication history data extracting unit, the authentication unit, the peripheral side control command detecting unit, A peripheral side authentication program for functioning as various means such as a peripheral side additional method switching means is stored. That is, the authentication program of the present invention is constituted by the main control side authentication program and the peripheral side authentication program.

(Processing 2 concerning transmission / reception of authentication information signal)
Below, the example of communication of the said authentication information signal performed between the main-control part 201 and a peripheral part is demonstrated. First, an example of the authentication information signal transmission procedure 2 by the CPU 211 (first computer) of the main control unit 201 will be described with reference to the flowchart of FIG.

  When the pachinko gaming machine 100 is turned on (turned on), the main control unit 201 executes the authenticated-side process shown in FIG. 15, and in step S 1500, as described in the individual identification value generation unit 312, 1 Alternatively, a plurality of individual identification values are generated and stored in the data storage unit 311 and then the process proceeds to step S1501. 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 S1501, 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. If the main control unit 201 determines that a control command has not occurred (S1501: No), the main control unit 201 proceeds to the process of step S1505. On the other hand, if the main control unit 201 determines that a control command is generated (S1501: Yes), in step S1502, 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 1503.

  In step S1503, the main control unit 201 determines whether or not the generated control command is a detection target control command indicated by detection target control command information stored in the data storage unit 311. If the main control unit 201 determines that the command is not a detection target control command (S1503: No), the process proceeds to step S1505. On the other hand, if the main control unit 201 determines that the command is a detection target control command (S1503: Yes), in step S1504, the plurality of additional methods are switched with reference to the switching information to indicate the switched additional method. The additional method data in the data storage unit 311 is updated, and then the process proceeds to step S1505.

  In step S1505, the main control unit 201 determines whether it is a predetermined authentication timing. If the main control unit 201 determines that it is not the authentication timing (S1505: No), the main control unit 201 proceeds to the process of step S1511. On the other hand, if the main control unit 201 determines that it is the authentication timing (S1505: Yes), the process proceeds to step S1506.

  In step S1506, the main control unit 201 randomly extracts one individual identification value from a plurality of types of individual identification values stored in the data storage unit 311 based on random numbers, extraction software, and the like. Are stored in the RAM 213 and the like, and then the process proceeds to step S1507. In step S1507, the main control unit 201 adds the extracted individual identification value to the latest history data stored in the data storage unit 311 using the addition method indicated by the addition method data (composite data). Value) is generated, and the process proceeds to step S1508.

  In step S1508, the main control unit 201 generates authentication information 1020 in which the authentication command C is set in the identification unit 1021 and the authentication data is set in the data unit 1022, and stores the authentication information 1020 in the data storage unit 311. Thereafter, the process proceeds to step S1509. In step S1509, the main control unit 201 encrypts the authentication information 1020 generated this time with a predetermined encryption method with the peripheral unit. In step S1510, the main control unit 201 stores the encrypted authentication information 1020 in the encrypted authentication information 1020. Based on this, an authentication information signal is generated and transmitted from the transmission unit 316 to the peripheral unit, and then the process proceeds to step S1511. If encryption is not required between the main control unit 201 and the peripheral unit, the processing in step S1509 is deleted, and the authentication information 1020 is transmitted to the peripheral unit as it is.

  In step S1511, 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 (S1511: No), the main control unit 201 returns to the process of step S1501 and repeats a series of processes. On the other hand, when the main control unit 201 determines that the power is turned off (S1511: Yes), the process according to this flowchart ends.

  Next, procedure 2 of the authentication information signal reception process by the peripheral CPUs 241 and 281 (second computer) will be described with reference to the flowchart of FIG.

  When executing the authentication side processing shown in FIG. 16, the peripheral unit refers to the peripheral side storage unit 332 to determine whether or not a control command is received from the main control unit 201 in step S1601. If it is determined that the peripheral unit has not received the control command (S1601: No), the process proceeds to step S1605. On the other hand, if it is determined that the peripheral unit has received the control command (S1601: Yes), the history generation method data and the history generation method of the peripheral storage unit 332 are the same as the main control unit 201 in step S1602. Based on the control command data to be generated, peripheral history data is generated and stored in the peripheral storage unit 332, and then the process proceeds to step S1603.

  In step S1603, the peripheral unit determines whether the received control command is a detection target control command indicated by detection target control command information stored in the peripheral storage unit 332 or not. When it is determined that the peripheral portion is not the detection target control command (S1603: No), the process proceeds to step S1605. On the other hand, when it is determined that the peripheral part is a detection target control command (S1603: Yes), in step S1604, a plurality of additional methods are switched by referring to the switching information, similarly to the main control unit 201, and the switching is performed. The additional method data in the peripheral storage unit 332 is updated so as to indicate the additional method, and then the process proceeds to step S1605.

  In step S1605, the peripheral unit determines whether the receiving unit 331 has received authentication information (authentication information signal) 1020 from the main control unit 201. If the peripheral unit determines that the authentication information 1020 has not been received (S1605: No), the process proceeds to step S1612. On the other hand, if it is determined that the authentication information 1020 has been received (S1605: Yes), the peripheral unit proceeds to the process of step S1606.

  In step S1606, the peripheral unit decrypts the received authentication information 1020 using a decryption method corresponding to the encryption method of the main control unit 201, extracts authentication data from the data unit 1022 of the authentication information 1020, and performs the authentication. Each of a plurality of types of expected values is deleted from the data based on the reverse method of the additional method data to extract a plurality of authentication history data, and the extracted plurality of authentication history data is stored in the peripheral storage unit 332. Then, the process proceeds to step S1607. If encryption is not required between the main control unit 201 and the peripheral unit, the decryption process in step S1606 is deleted.

  In step S1607, the peripheral unit compares the plurality of extracted authentication history data with the latest peripheral history data stored in the peripheral storage unit 332, and authentication history data matching the peripheral history data is found. The determination result of whether or not it exists is stored in the peripheral storage unit 332 and the like, and then the process proceeds to step S1608.

  If there is a match in step S1608 (S1608: Yes), the history data match and the continuity of communication is valid. Therefore, in step S1609, the peripheral unit authenticates the main control unit 201. Is established, and then the process proceeds to step S1612. On the other hand, if there is no match in the peripheral part (S1608: No), the continuity of communication is not valid or the authentication information is invalid. In step S1611, for example, a notification signal is output from the speaker 262 (see FIG. 2) or the like, and then the process proceeds to step S1612.

  In step S1612, the peripheral unit determines whether or not the pachinko gaming machine 100 is powered off. If the peripheral portion determines that the power is not turned off (S1612: No), the processing returns to step S1601, and a series of processing is repeated. On the other hand, when it is determined that the power source is turned off (S1612: Yes), the peripheral unit ends the process according to this flowchart.

(Example of additional method switching procedure in authentication processing)
Next, in the pachinko gaming machine 100, an example of authentication when the main control board 310 and the peripheral board 330 use two individual identification values and expected values will be described with reference to the drawing of FIG.

  First, as a precondition, the main control board 310 stores two individual identification values A1 and A2 in the data storage unit 311 in advance, and the addition method D1 is “+” and the addition method D2 is “−”. On the other hand, the peripheral board 330 stores two expected values B1 and B2 that match the individual identification values A1 and A2 of the main control board 310 in the peripheral storage unit 332 in advance, and the same additional method as the main control board 310 D1 and D2 are stored. The main control board 310 and the peripheral board 330 are initially set to the additional method D1, and the switching information indicates switching in the order of the additional methods D1 and D2.

  In FIG. 17, the main control board 310 that is the person to be authenticated generates individual identification values A1 and A2 in response to the activation of the pachinko gaming machine 100, and the generated individual identification values A1 and A2 are stored in the data storage unit 311. Store (S1700). Thereafter, when the main control board 310 transmits a control command to 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 unit 311 (S1701). The main control board 310 generates history data based on the transmitted control command and the history generation method and stores the history data in the data storage unit 311 (S1702). On the other hand, when the peripheral board 330 receives the control command, the peripheral board 330 stores the received control command in the peripheral-side storage unit 332 and performs a predetermined process corresponding to the control command (S1751). Then, similarly to the main control board 310, the peripheral board 330 generates peripheral side history data based on the received control command and history generation method, and stores it in the peripheral side storage unit 332 (S1752).

  Thereafter, when the main control board 310 randomly selects one individual identification value A1 from the two individual identification values A1 and A2 (S1703), the additional method D1 is set in the additional method data. Then, authentication information 1020 having authentication data C1 obtained by adding (adding) the selected individual identification value A1 to the latest history data is generated and transmitted to the peripheral board 330 (S1704). On the other hand, the peripheral board 330, like the main control board 310, has the additional method D1 set in the additional method data. Therefore, each of the plurality of expected values B1, B2 from the authentication data C1 of the received authentication information 1020. Is deleted (deleted) to extract authentication history data C1-B1 and C1-B2, and based on whether the authentication history data C1-B1 and C1-B2 match the latest peripheral history data. Then, authentication based on the continuity of communication of the control command with the main control board 310 is performed (S1753). As a result, since the authentication information 1020 has the authentication data C1 to which the individual identification value A1 is added, the authentication history data C1-B1 from which the expected value B1 that matches the individual identification value A1 is deleted is the main control. Since it becomes the history data of the board 310, if the authentication information 1020 is valid, the authentication history data C1-B1 matches the peripheral history data.

  When the main control board 310 transmits the next control command to the peripheral board 330, the main control board 310 stores the control command in the data storage unit 311 (S1705). Then, the main control board 310 generates history data based on the transmitted control command and history generation method and stores it in the data storage unit 311 (S1706). On the other hand, when receiving the control command, the peripheral board 330 stores the received control command in the peripheral storage unit 332 and performs a predetermined process corresponding to the control command (S1754). Then, similarly to the main control board 310, the peripheral board 330 generates peripheral side history data based on the received control command and history generation method and stores it in the peripheral side storage unit 332 (S1755).

  After that, when the main control board 310 randomly selects one individual identification value A2 from the two individual identification values A1 and A2 (S1707), the additional method D1 is set in the additional method data. Then, authentication information 1020 having authentication data C2 obtained by adding (adding) the selected individual identification value A2 to the latest history data is generated and transmitted to the peripheral board 330 (S1708). On the other hand, in the peripheral board 330, as with the main control board 310, since the additional method D1 is set in the additional method data, each of the plurality of expected values B1, B2 from the authentication data C2 of the received authentication information 1020. Is deleted (deleted) to extract authentication history data C2-B1 and C2-B2, and based on whether the authentication history data C2-B1 and C2-B2 match the latest peripheral history data. Then, authentication based on the continuity of communication of the control command with the main control board 310 is performed (S1756). As a result, since the authentication information 1020 has the authentication data C2 to which the individual identification value A2 is added, the authentication history data C2-B2 from which the expected value B2 that matches the individual identification value A2 is deleted is the main control. Since it becomes the history data of the board 310, if the authentication information 1020 is authentic, the authentication history data C2-B2 matches the peripheral history data.

  When the main control board 310 transmits the next control command to the peripheral board 330, the main control board 310 stores the control command in the data storage unit 311 (S1709). Then, the main control board 310 generates history data based on the transmitted control command and the history generation method, and stores it in the data storage unit 311 (S1710). When the main control board 310 detects the detection target control command indicated by the detection target control command information (S1711), since the additional method data in the data storage unit 311 indicates the additional method D1, the switching information is The system switches to the next additional method D2 shown, and updates the additional method data to indicate the additional method D2 (S1712).

  On the other hand, when the peripheral board 330 receives the control command, the peripheral board 330 stores the received control command in the peripheral-side storage unit 332 and performs a predetermined process corresponding to the control command (S1757). Then, similarly to the main control board 310, the peripheral board 330 generates peripheral side history data based on the received control command and history generation method and stores it in the peripheral side storage unit 332 (S1758). When the peripheral board 330 detects reception of the detection target control command indicated by the detection target control command information in the peripheral storage unit 332 (S1759), the additional method data in the peripheral storage unit 332 indicates the additional method D1. Therefore, it switches to the next additional method D2 indicated by the switching information, and updates the additional method data to indicate the additional method D2 (S1760).

  Thereafter, when the main control board 310 randomly selects one individual identification value A2 from the two individual identification values A1 and A2 (S1713), the additional method D2 is switched and set in the additional method data. Therefore, the authentication information 1020 having the authentication data C3 obtained by subtracting (adding) the selected individual identification value A2 from the latest history data is generated and transmitted to the peripheral board 330 (S1714). On the other hand, since the peripheral board 330 is set by switching the additional method D2 to the additional method data, similarly to the main control board 310, the authentication data C3 of the received authentication information 1020 includes a plurality of expected values B1, Each of B2 is added (deleted) to extract authentication history data C3 + B1, C3 + B2, and based on whether the authentication history data C3 + B1, C3 + B2 and the latest peripheral history data match, the main control board 310 Authentication based on the continuity of communication of the control command is performed (S1761). As a result, since the authentication information 1020 has the authentication data C3 to which the individual identification value A2 is added, the authentication history data C3 + B2 from which the expected value B2 that matches the individual identification value A2 is deleted is the main control board 310. If the authentication information 1020 is legitimate, the authentication history data C3 + B2 matches the peripheral history data. Thereafter, the same processing is performed.

  According to the pachinko gaming machine 100 described above, as in the first embodiment, the main control board 310 generates the authentication information 1020 in which the randomly selected individual identification value is added to the history data indicating the history of the control command. Since the peripheral board 330 uses the history data of the authentication information 1020 for authentication of the main control board 310, the randomly selected individual identification value changes irregularly. The regularity of the authentication information 1020 is lost, and it can be expected to prevent unauthorized analysis of the authentication information 1020. Further, the main control board 310 only needs to randomly select one individual identification value from a plurality of types of individual identification values and add it to the history data, so that the amount of code of the program stored in the main control board 310 increases. In addition, an increase in processing load on the main control board 310 can be suppressed. Further, since the main control board 310 generates at least one of a plurality of types of individual identification values based on the stored data of the main control board 310, the generated individual identification values are stored in the main control board 310. Since it is not necessary to store in advance, an increase in the amount of data stored in advance for authentication of the main control board 310 in the pachinko gaming machine 100 can be suppressed. Since the main control board 310 can store a plurality of types of individual identification values in advance before generating the authentication information, it is not necessary to perform a complicated operation when generating the authentication information 1020. An increase in the processing load of 310 can be prevented. On the other hand, since the peripheral board 330 is configured to confirm and authenticate the communication continuity of the control command based on the history data, it can detect unauthorized communication switching due to an unauthorized control command. It can contribute to prevention of switching. In addition, since the peripheral substrate 330 extracts the authentication history data from the authentication information 1020 using a plurality of types of expected values, the authentication history data and the peripheral data are extracted when the regular individual identification value is not added to the history data. Since the side history data does not match, fraud can be reliably detected. Further, since the peripheral board 330 confirms all combinations of each of a plurality of types of expected values and the authentication information 1020 and authenticates the main control board 310, the main control board 310 simply sets the individual identification value. It is only necessary to make a selection, and there is no need to include complicated processing. Further, since the main control board 310 generates the individual identification value based on the stored data, when the stored data of the main control board 310 is altered, the individual control value different from the expected value of the peripheral board 330 is controlled. Since the board 310 is generated, the peripheral board 330 can be prevented from authenticating the main control board 310 and contribute to fraud prevention. Further, for example, when an illegal board or the like intervenes between the main control board 310 and the peripheral board 330, the processing load must be increased because the analysis load on the illegal board increases. Increasing the degree can contribute to deterring the production of illegal substrates. Accordingly, the processing load on the main control board 310 can be minimized, the communication continuity of the control command can be confirmed, and the analysis of the authentication information 1020 used for authentication can be made difficult.

  In the pachinko gaming machine 100 described above, the main control board 310 generates at least one of a plurality of types of individual identification values based on the stored data in response to the activation of the pachinko gaming machine 100. Therefore, it is not necessary to store the generated individual identification value in advance, and the authentication of the main control board 310 can be performed immediately after the pachinko gaming machine 100 is started. It can contribute to improvement. Further, when the main control board 310 generates an individual identification value that is different from the expected value of the peripheral board 330, it can be determined that the stored data has been tampered with before activation, which can contribute to fraud prevention.

  In addition, according to the pachinko gaming machine 100 described above, the main control board 310 and the peripheral board 330 are switched based on a predetermined switching method according to the detection of the detection target control command. Even if the same individual identification value is added to the same history data, the generated authentication information 1020 is different, so that unauthorized analysis can be made even more difficult. In addition, since the detection target control command is the switching timing of the additional method, the main control board 310 and the peripheral board 330 can be switched synchronously even after the pachinko gaming machine 100 is activated.

  Further, in the pachinko gaming machine 100 described above, if the history data and the peripheral 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 peripheral history data to values obtained by calculating past history data, analysis by an unauthorized analyst can be made even more difficult.

[Example 3]
In the pachinko gaming machine 100 according to the second embodiment described above, the case where the main control board 310 and the peripheral board 330 switch the addition method according to the detection of the detection target control command has been described. A case where both the history generation methods are switched will be described.

  Hereinafter, an example of the pachinko gaming machine 100 according to the third embodiment will be described. In addition, about the same part as the structure of Example 2 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)
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 selection unit 314, the authentication information generation unit 315, the transmission unit 316, the control command detection unit 316, and the second embodiment described above. An additional method switching unit 317 and a history generation method switching unit 318 indicated by a broken line in FIG. 3 are included.

  The history generation method switching unit 318 corresponds to the history generation method switching means of the present invention, and the history generation method used by the history data generation unit 313 in accordance with the detection by the control command detection unit 316 is a predetermined history. Switch by switching method. In the present embodiment, as the history switching method, history switching information with a plurality of history generation methods as a table is stored in the data storage unit 311 together with the switching information. An example of the history switching information is a table that defines different history generation methods and their switching order, similar to the switching information. Then, the history generation method switching unit 318 switches history generation method data stored in the data storage unit 311 based on the history switching information in accordance with the detection of the control command detection unit 316. Thus, the history data generation unit 313 generates history data by the history generation method switched by the history generation method switching unit 318 by referring to the history generation method data in the data storage unit 311.

  Subsequently, the peripheral board 330 includes the receiving unit 331, the peripheral side storage unit 332, the peripheral side history data generation unit 333, the authentication history data extraction unit 334, the authentication unit 335, and the peripheral side control command detection unit of the second embodiment described above. 336, a peripheral side addition method switching unit 337, and a peripheral side history generation method switching unit 338 indicated by a broken line in FIG.

  The peripheral history generation method switching unit 338 corresponds to the peripheral history generation method switching means of the present invention, and the history generation used by the peripheral history data generation unit 333 in response to detection by the peripheral control command detection unit 336. The method is switched by the same history switching method (history switching information) as that of the main control board 310. That is, the peripheral board 330 stores the same history switching information as that of the main control board 310 in the peripheral storage unit 332 in advance. Then, similarly to the main control board 310, the peripheral history generation method switching unit 338 uses the history used by the peripheral history data generation unit 333 in response to detection of the detection target control command of the peripheral control command detection unit 336. The generation method data is switched by a predetermined history switching method. Accordingly, the peripheral history data generation unit 333 generates peripheral history data by the history generation method switched by the peripheral history generation method switching unit 338 by referring to the history generation method data of the peripheral storage unit 332. Will do.

  In the present embodiment, a case will be described in which the CPU 211 of the main control board 310 functions as the first computer in the claims and each of the CPUs 241 and 281 of the peripheral board 330 functions as the second 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 selection unit, an authentication information generation unit, a transmission unit, a control command detection unit, and an additional method switching unit. The main control side authentication program for functioning as various means such as a history generation method switching means is stored. In addition, each of the ROMs 242 and 282 of the peripheral board 330 includes the receiving unit, the peripheral side history data generating unit, the authentication history data extracting unit, the authentication unit, the peripheral side control command detecting unit, A peripheral side authentication program for functioning as various means such as a peripheral side addition method switching unit and a peripheral side history generation method switching unit is stored. That is, an authentication program is constituted by the main control side authentication program and the peripheral side authentication program.

(Other processing related to transmission / reception of authentication information signal)
Below, the communication example of the said authentication information signal performed between the main control part 201 and a peripheral part in the structure mentioned above is demonstrated. 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. 15 described above. Since the basic processing of the flowchart shown in FIG. 15 is the same, 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 authentication-side processing shown in FIG. , Switching a plurality of additional methods with reference to the switching information, updating the additional method data in the data storage unit 311 to indicate the switched additional methods, and generating a plurality of histories with reference to the history switching information The system is switched, the history generation system data in the data storage unit 311 is updated to indicate the switched history generation system, and then the process proceeds to step S1505. Thereafter, the processes of steps S1505 to S1511 described above are executed.

  Next, a procedure of other reception processing of the authentication information signal by the peripheral CPUs 241 and 281 (second computer) will be described with reference to the flowchart of FIG. Since the basic processing of the flowchart shown in FIG. 16 is the same, only different parts will be described.

  The peripheral unit executes the authentication-side process shown in FIG. 16, and when the processes in steps S1601 to S1603 are completed, in step 1604, the plurality of additional methods are switched with reference to the switching information, and the switched additional method is indicated. As described above, the additional method data in the peripheral storage unit 332 is updated, a plurality of history generation methods are switched with reference to the history switching information, and the history generation in the peripheral storage unit 332 is performed to indicate the switched history generation method. The method data is updated, and then the process proceeds to step S1605. Thereafter, the processes of steps S1605 to S1612 described above are executed.

(Example of switching procedure between additional method and history generation method)
Next, in the pachinko gaming machine 100, in the authentication example in the case where the main control board 310 and the peripheral board 330 use two individual identification values and expected values, the main control board 310 shows the step S1712 in FIG. Only the 17th step S1760 is changed as follows.

  When the main control board 310 detects the detection target control command indicated by the detection target control command information (S1711), since the additional method data in the data storage unit 311 indicates the additional method D1, the next information indicated by the switching information is displayed. Is switched to the additional method D2, and the additional method data is updated to indicate the additional method D2, and the next history generation method indicated by the history switching information is switched, and the history generation method data is updated to indicate this. (S1712).

  On the other hand, when the peripheral substrate 330 detects reception of the detection target control command indicated by the detection target control command information in the peripheral storage unit 332 (S1759), the additional method data in the peripheral storage unit 332 indicates the additional method D1. Switch to the next additional method D2 indicated by the switching information, update the additional method data to indicate the additional method D2, and switch to the next history generation method indicated by the history switching information. As shown, the history generation method data is updated (S1760). Thereafter, the same processing is performed.

  According to the pachinko gaming machine 100 described above, as in the second embodiment, the main control board 310 generates the authentication information 1020 in which the randomly selected individual identification value is added to the history data indicating the history of the control command. Since the peripheral board 330 uses the history data of the authentication information 1020 for authentication of the main control board 310, the randomly selected individual identification value changes irregularly. The regularity of the authentication information 1020 is lost, and it can be expected to prevent unauthorized analysis of the authentication information 1020. Further, the main control board 310 only needs to randomly select one individual identification value from a plurality of types of individual identification values and add it to the history data, so that the amount of code of the program stored in the main control board 310 increases. In addition, an increase in processing load on the main control board 310 can be suppressed. Further, since the main control board 310 generates at least one of a plurality of types of individual identification values based on the stored data of the main control board 310, the generated individual identification values are stored in the main control board 310. Since it is not necessary to store in advance, an increase in the amount of data stored in advance for authentication of the main control board 310 in the pachinko gaming machine 100 can be suppressed. Since the main control board 310 can store a plurality of types of individual identification values in advance before generating the authentication information, it is not necessary to perform a complicated operation when generating the authentication information 1020. An increase in the processing load of 310 can be prevented. On the other hand, since the peripheral board 330 is configured to confirm and authenticate the communication continuity of the control command based on the history data, it can detect unauthorized communication switching due to an unauthorized control command. It can contribute to prevention of switching. In addition, since the peripheral substrate 330 extracts the authentication history data from the authentication information 1020 using a plurality of types of expected values, the authentication history data and the peripheral data are extracted when the regular individual identification value is not added to the history data. Since the side history data does not match, fraud can be reliably detected. Further, since the peripheral board 330 confirms all combinations of each of a plurality of types of expected values and the authentication information 1020 and authenticates the main control board 310, the main control board 310 simply sets the individual identification value. It is only necessary to make a selection, and there is no need to include complicated processing. Further, since the main control board 310 generates the individual identification value based on the stored data, when the stored data of the main control board 310 is altered, the individual control value different from the expected value of the peripheral board 330 is controlled. Since the board 310 is generated, the peripheral board 330 can be prevented from authenticating the main control board 310 and contribute to fraud prevention. Further, for example, when an illegal board or the like intervenes between the main control board 310 and the peripheral board 330, the processing load must be increased because the analysis load on the illegal board increases. Increasing the degree can contribute to deterring the production of illegal substrates. Accordingly, the processing load on the main control board 310 can be minimized, the communication continuity of the control command can be confirmed, and the analysis of the authentication information 1020 used for authentication can be made difficult.

  In the pachinko gaming machine 100 described above, the main control board 310 generates at least one of a plurality of types of individual identification values based on the stored data in response to the activation of the pachinko gaming machine 100. Therefore, it is not necessary to store the generated individual identification value in advance, and the authentication of the main control board 310 can be performed immediately after the pachinko gaming machine 100 is started. It can contribute to improvement. Further, when the main control board 310 generates an individual identification value that is different from the expected value of the peripheral board 330, it can be determined that the stored data has been tampered with before activation, which can contribute to fraud prevention.

  In addition, according to the pachinko gaming machine 100 described above, the main control board 310 and the peripheral board 330 are switched based on a predetermined switching method according to the detection of the detection target control command. Even if the same individual identification value is added to the same history data, the generated authentication information 1020 is different, so that unauthorized analysis can be made even more difficult. In addition, since the detection target control command is the switching timing of the additional method, even after the pachinko gaming machine 100 is activated, the main control unit and the peripheral unit can be switched synchronously.

  Furthermore, according to the pachinko gaming machine 100 described above, the main control board 310 and the peripheral board 330 switch the addition method based on a predetermined switching method according to the detection of the detection target control command, and the history generation method. Is switched by a predetermined history switching method, so that the addition method for adding the individual identification value to the history data is switched and the history data history generation method is also switched, so that the authentication information 1020 to be generated is continued. It is possible to make illegal analysis even more difficult.

  Further, in the pachinko gaming machine 100 described above, if the history data and the peripheral 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 peripheral history data to values obtained by calculating past history data, analysis by an unauthorized analyst can be made even more difficult.

  Subsequently, in the pachinko gaming machine 100 according to the second embodiment described above, a case where a plurality of types of additional methods are switched in accordance with detection of a detection target control command has been described, but this “additional method” is replaced with a “history generation method”. Thus, the main control board 310 and the peripheral board 330 can switch the history generation method based on a predetermined history switching method in accordance with the detection of the detection target control command. Even if the individual identification value is added, the authentication information to be generated is different, so that unauthorized analysis can be made even more difficult. In addition, since the detection target control command can be set as the switching timing of the additional method, the main control board 310 and the peripheral board 330 can be switched synchronously even after the pachinko gaming machine 100 is activated. The switching method of the history generation method can be realized by using the switching method of the third embodiment.

  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.
