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.

JP 11-333108 A JP 2002-18095 A

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

  In addition, as in Patent Document 2 described above, when a state monitoring command different from the control command is transmitted from the main control board to the controlled board, the gaming machine may be cheated ("got" action). Yes, since the state monitoring command is likely to be illegally analyzed by the unauthorized control board or the like interposed between the main control side and the controlled side, if the analysis cannot be made difficult, It was difficult to realize with. Further, if complicated encryption is performed at the time of transmission, there is a problem that processing of each of the regular main control board and the controlled board becomes complicated and processing load increases.

  Furthermore, in order to prevent unauthorized analysis, it may be possible to complicate authentication processing using a plurality of types of authentication commands. However, in conventional gaming machines, a plurality of types of control commands are used. Therefore, in order to add a plurality of new authentication commands (authentication information) to this conventional command system, it is necessary to newly add processing corresponding to each command to the main control side, Since the processing on the main control side becomes complicated, it is difficult to realize in a gaming machine.

  When various data used for authentication are changed in response to the generation of an authentication command, when attention is paid to the authentication command, for example, the change target, change timing, change method, etc. are illegally analyzed. Therefore, there is a need to make unauthorized analysis even more difficult without complicating normal processing.

  In order to solve the above-described problems caused by the prior art, the present invention performs an unauthorized analysis of the authentication information and the change using the authentication information even if the data used for authentication and authentication is changed with one type of authentication information. An object is to provide a gaming machine and a gaming machine authentication method that can be made difficult.

Corresponding to the first inspection value and the second inspection value correspond to the peripheral detection target switching step to be switched in the control command and the first expectation value or the second expectation value that coincided in the authentication of the authentication data. characterized in that the data type associated advance as to identify the next data type including a specifying step of updating said peripheral side type information.

  According to the gaming machine authentication method of the present invention described in claim 10, when the type information indicates the authentication data, the main control unit stores the first inspection value stored in the inspection value storage means. When one inspection value is randomly selected from the second inspection value and the third inspection value, authentication data having the selected one inspection value is generated. The main control unit determines the data type associated with the selected first inspection value, second inspection value, and third inspection value in advance as the next data type. Further, the main control unit generates expected value changing data for changing each of the inspection value and the expected value when the type information indicates the expected value changing data. The main control unit can generate authentication information having the generated authentication data or expected value change data, and can transmit the generated authentication information to the peripheral unit. Then, the main control unit updates the type information stored in the type information storage means so as to indicate the determined next data type. Then, after generating the expected value change data, the main control unit detects the generation or transmission of a predetermined detection target control command from a plurality of types of control commands in the gaming machine, and in response to the detection At least one inspection value determined in advance among the first to third inspection values can be changed by the expected value changing data. In addition, when generation or transmission of authentication information of authentication data having the third inspection value is detected during detection of generation or transmission of the detection target control command, among a plurality of predetermined detection target control commands The detection target control command of the detection target can be switched. On the other hand, when the data type of the peripheral side type information indicates the authentication data, the peripheral unit includes authentication data of authentication information received from the main control unit and three types of first expected value, second expected value, The main control unit can be authenticated by comparing each with the third expected value. When the authentication of the main control unit is established, the peripheral unit specifies the data type associated with the expected value that matches the authentication data of the authentication information as the next data type and updates the peripheral type information can do. Further, when the data type of the peripheral side type information indicates the expected value change data, the peripheral unit receives the expected value change data from the main control unit, and thereafter the same detection target as the main control unit The reception of the control command can be monitored, and the expected value can be changed with the expected value changing data in response to the detection of the reception of the detection target control command. Further, when the reception of the authentication information of the authentication data having the third inspection value is detected from the main control unit during the generation or transmission detection of the detection target control command, a plurality of predetermined numbers are set as in the main control unit. It is possible to switch the detection target control command to be detected among the types of detection target control commands.

  As described above, according to the present invention, the main control unit associates two kinds of data types of the authentication information with each of the first inspection value and the second inspection value of the three kinds of inspection values, and Since authentication data is generated with one inspection value or second inspection value, and authentication information including the authentication data is generated and transmitted to the peripheral portion, the peripheral portion corresponds to the data type corresponding to the expected value. By attaching, it is possible to establish the authentication of the main control unit and specify the data type of the authentication information to be received next time when the inspection value and the expected value that the authentication information has match, An unauthorized analyst can be prevented from using authentication information illegally. In addition, since the inspection value and the expected value change timing based on the expected value change data are associated with a predetermined detection target control command from a plurality of types of control commands, the expected value change data is generated and transmitted. Since the interval between the data and the change using the data can be irregular, it is possible to make illegal analysis difficult. The peripheral unit can change the expected value with the expected value change data received from the main control unit according to the detection of the same detection target control command as the main control unit, and can match the inspection value of the main control unit Therefore, the inspection value and the expected value can be changed in a uniform manner between the main control unit and the peripheral part, and the analysis by an unauthorized analyst can be made even more difficult. In addition, the main control unit and the peripheral unit align detection target control commands among a plurality of types of predetermined detection target control commands in response to detection of generation or transmission and reception of authentication information having a third inspection value. Therefore, the change timing based on the expected value change data can be made more complicated, making illegal analysis difficult. Since only one type of authentication information has to be used, it is possible to minimize the addition to the conventional command system and prevent the processing of the main control unit from becoming complicated. Furthermore, since the peripheral part can detect that the authentication information has been used illegally by the fraud analyst based on the data type of the authentication information, the authentication strength of the authentication information can be increased. Therefore, even if data used for authentication and authentication is changed with one type of authentication information, there is an effect that it is possible to make unauthorized analysis of the authentication information and the change difficult.

  In the gaming machine described above, when the main control unit generates authentication information having the third inspection value again before detecting the detection target control command, the peripheral unit also detects the detection target control command before detecting the detection target control command. When the authentication information having the third inspection value is received again, it is possible to prevent the detection target control command from being switched before detecting the detection target control command if the switching of the detection target control command is prohibited. Processing complexity can be prevented. And since the authentication information which has a 3rd test value can be used like a dummy between a main control part and a peripheral part, an illegal analysis can be made still more difficult.

  In the gaming machine described above, the main control unit, when detecting the generation or transmission of the detection target control command, when the number of again generated authentication information having the third inspection value satisfies a predetermined switching condition, In addition, when the peripheral unit detects the reception of the detection target control command from the main control unit, the number of times the authentication information having the third inspection value is received again satisfies the same switching condition as the main control unit. If the detection target control command is switched again among a plurality of predetermined detection target control commands, the detection target control command can be switched before the change by the expected value change data. Can be further complicated. Also, depending on the switching condition, there are cases where the detection target control command is switched and switching is not performed depending on the detection of the authentication information having the third inspection value, so that unauthorized analysis can be made even more difficult.

  In the above gaming machines, for example, jackpot-related commands in gaming machines such as jackpot reach command, jackpot start command, jackpot command, jackpot end command, etc. are set as detection target control commands. Therefore, if an invalid jackpot related command is sent to the peripheral part holding the expected value change data, the peripheral part detects it as a detection target control command, changes the expected value, and the main control The inspection value of the part and the expected value of the peripheral part can be made inconsistent. Therefore, it is possible to contribute to improving the accuracy of detecting the occurrence of fraud.

  In the gaming machine described above, since the expected value change data is a test value that is a predetermined initial value and a correction value that changes the expected value, the main control unit and the peripheral unit have predetermined test values and expected values. Since it is only necessary to change the value with the expected value changing data, the changing process can be simplified.

  In the above-mentioned gaming machine, since the expected value change data is the coefficient value for changing the previously changed inspection value and expected value, the inspection value and expected value can be accumulated and changed. Analysis of values can be made even more difficult, and unauthorized use of inspection values and expected values can be prevented.

  In the above-described gaming machine, the expected value changing data for absorbing the difference between the inspection value and the expected value is stored in the peripheral portion in advance and the expected value changing data for absorbing the difference between the inspection value and the expected value is the main control. Since the part has generated and transmitted to the peripheral part, the expected value can be matched with the inspection value of the main control part by changing the expected value with the expected value change data by the peripheral part. Therefore, it is possible to make it difficult to analyze and use the inspection value and the expected value by an unauthorized analyst.

(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, a switching determination unit 312, a determination unit 313, a first extraction unit 314, a second extraction unit 315, An authentication data generation unit 316, an expected value change data generation unit 317, an authentication information generation unit 318, a transmission unit 319, an update unit 320, a control command detection unit 321, a main control side change unit 322, and a detection target switching unit 323 are provided. Configured. The main control board 310 is formed of a board different from the peripheral board 330 and is electrically connected so as to communicate with the peripheral board 330.

  The data storage unit 311 corresponds to the inspection value storage unit and the type information storage unit of the present invention, and includes an inspection value, authentication information, type information, authentication data, expected value change data, detection target control command information, switching information, Etc. 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 authentication information transmitted to the peripheral unit. The authentication information stored in the data storage unit 311 can have various different embodiments such as a configuration for storing only one transmission, and a configuration for storing a plurality of transmissions in time series.

  The authentication data is data used by the peripheral board 330 (peripheral part) for authentication of the main control board 310 (main control part), and is generated by the CPU 211 described above. The expected value changing data is data for changing the three types of inspection values of the main control unit 201 and the three types of expected values of the peripheral unit. Generate irregularly by executing, or generate based on an arbitrary counter, a predetermined value, or the like.

  The data storage unit 311 stores three different kinds of inspection values predetermined for the pachinko gaming machine 100 at the time of design, manufacture, and the like. The three types of inspection values include a first inspection value, a second inspection value, and a third inspection value. For example, checksums of three different predetermined areas in the ROM 212 of the main control unit 201 are determined in advance. Specific values, odd and even numbers, magnitude-related values, and the like.

  Each of the first inspection value and the second inspection value is associated one-to-one with the data type indicating which data the authentication information has among the above-described authentication data and expected value change data. . Specifically, type data for indicating the data type is associated with each of the first test value and the second test value. The third inspection value is defined as switching of a detection target control command to be described later.

  The third inspection value of the present embodiment is stored in the data storage unit 311 in association with detection target control command information indicating a detection target control command to be detected by the control command detection unit 321 described later. In the detection target control command information, data indicating the latest detection target control command is set, and data set according to switching of the detection target control command changes. In this embodiment, in order to simplify the description, a case will be described in which two types of control commands, a predetermined jackpot start command and a jackpot end command, are switched as detection target control commands. The third inspection value may be stored in the data storage unit 311 in association with the above-described data type.

  In addition, the third inspection value can store the detection target control command in association with the switching information indicating the switching method. The switching information is information indicating a plurality of types of detection target control commands to be switched in advance from among a plurality of types of control commands and a switching method of the plurality of types of detection target control commands. . As an example of the switching information, a switching table indicating a plurality of types of detection target control commands determined in advance, a method for switching detection targets based on the switching order, and a plurality for selecting from a plurality of types of detection target control commands And a method of switching the detection target based on the selection pattern and the switching order of the plurality of selection patterns. And switching information can also be set as embodiment integrated as a part of program for implement | achieving this invention.

  In the present embodiment, a case where three types of first to third inspection values and corresponding first to third expected values are used will be described. Instead, a plurality of third inspection values and third expected values are used. By using types, it is possible to obtain three or more types of inspection values and expected values. In that case, an embodiment that uses only a predetermined one of the two types of third inspection value and the third expected value, or different switching information for each of the two types of third inspection value and the third expected value. This can be dealt with by an embodiment that uses the switching information for both of them.

  The type information has a data structure indicating the data type of the authentication information generated by the main control unit 201 this time. For example, the type information includes current type data and next type data, and each type of data is data for identifying authentication data and expected value change data. It should be noted that the type information can have a data structure of only the current type data by setting the next type data at the end of the authentication process.

  The switching determination unit 312 corresponds to the switching determination unit of the present invention, and randomly determines whether to switch the different data types. That is, the switching determination unit 312 is means for determining which data type to switch between the authentication data and the expected value changing data, or to switch the detection target control command. For example, the switching determination unit 312 makes irregular determination by using a random number, a table, or the like, thereby making it difficult for the fraud analyst to analyze it illegally.

  The determination unit 313 corresponds to a determination unit of the present invention. When the switching determination unit 312 determines to switch the data type, the data type of the authentication information that the main control board 310 generates next time is the authentication data and the expected value. Randomly determined from the two types of data for change. Then, the determination unit 313 determines the next data type irregularly using, for example, a random number, a table, or the like so that the authentication data and the expected value change data are in an irregular order. It makes it difficult for an analyst to analyze it illegally.

  The first extraction unit 314 corresponds to a first extraction unit of the present invention, and stores a first inspection value or a second inspection value associated with the next data type determined by the determination unit 313 as a data storage unit (inspection value storage). Means) Extract from 311 and store the extracted inspection value in the RAM 213 or the like. Then, one inspection value extracted by the first extraction unit 314 becomes an inspection value used as authentication data for the authentication information generated this time.

  The second extraction unit 315 corresponds to the second extraction means of the present invention, and stores the third inspection value when the switching determination unit 312 determines not to switch the data type, that is, to switch the detection target control command. Unit (inspection value storage means) 311, and the extracted third inspection value is stored in the RAM 213 or the like. Then, the third inspection value extracted by the second extraction unit 315 becomes the inspection value used as authentication data for the authentication information generated this time.

  The authentication data generation unit 316 corresponds to the authentication data generation unit of the present invention. When the type information stored in the data storage unit 311 indicates authentication data, the authentication data generation unit 316 Authentication data having the inspection value extracted by the extraction unit 315 is generated, and the authentication data is stored in the data storage unit 311 or the like. Then, the authentication data generation unit 316 generates authentication data for the extracted inspection value using a data type that is a predetermined initial value in the first process, and in the second and subsequent processes, Since the next data type is determined by the determination unit 313 in this process, authentication data for the extracted inspection value is generated using the next data type. The authentication data generated in this way is one of three types of test values that are randomly extracted. In this embodiment, the case where the authentication data is the extracted inspection value will be described. Instead, for example, the extraction is performed by a predetermined calculation method between the main control unit 201 and the peripheral unit. It is also possible to use a value obtained by calculating the inspection value.

  The expected value change data generation unit 317 corresponds to the expected value change data generation means of the present invention. When the type information stored in the data storage unit 311 indicates the expected value change data, the determination unit In response to the determination of the expected value change data by 313, the expected value change data for changing each of the three types of inspection values of the main control board 310 and the three types of expected values of the peripheral board 330 is generated. The value change data is stored in the data storage unit 311 or the like. The expected value change data generation unit 317 generates expected value change data so as to have different values, irregular values, and the like at an arbitrary generation timing. The expected value changing data includes correction values, coefficient values, and the like, which will be described later.

  The authentication information generation unit 318 corresponds to the authentication information generation unit of the present invention, and includes authentication data generated by the authentication data generation unit 316 or expected value change data generated by the expected value change data generation unit 317. Generate information. When the authentication information generation unit 318 of the present embodiment generates authentication information having either one of authentication data or expected value change data and an authentication command different from the control command of the pachinko gaming machine 100 Will be described. Alternatively, the authentication information may have a data structure further including other data.

  The transmission unit 319 corresponds to a transmission unit of the present invention, and transmits each of the authentication information generated by the authentication information generation unit 318 and the control command data to the peripheral board (peripheral unit) 330 individually at different timings. Then, the transmission unit 319 of this embodiment transmits each of a plurality of types of control command data from the main control board 310 to the peripheral board 330 as a control signal. For example, the transmission unit 319 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.

  The update unit 320 corresponds to the update unit of the present invention, and updates the type information stored in the data storage unit 311 so as to indicate the next data type determined by the determination unit 313. The next data type indicated by the type information is used as the current data type in the next authentication process in the main control board 310.

  The control command detection unit 321 corresponds to a control command detection unit of the present invention, and generates authentication information having expected value change data by the authentication information generation unit 318 or transmits the authentication information to the peripheral part by the transmission unit 319. Accordingly, the generation or transmission of a detection target control command that is predetermined and set in the detection target control command information from a plurality of types of control commands in the pachinko gaming machine 100 is detected. That is, the control command detection unit 321 sets the change timing of the expected value change data generated by the expected value change data generation unit 317 when the detection target control command is generated or when it is transmitted to the peripheral part. 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 main control side changing unit 322 corresponds to the main control side changing unit of the present invention, and the data storage unit 311 (inspection value storage unit) is detected in response to the detection or generation of the detection target control command by the control command detection unit 321. ) Stored in the expected value changing data generation unit 317 generates at least one of the three types of the first inspection value, the second inspection value, and the third inspection value. Change based on data. The main control side changing unit 322 changes the three types of inspection values using a change method and expected value changing data that are predetermined between the main control board 310 and the peripheral board 330. As the change method, for example, various calculation methods such as +, −, *, /, AND, OR, XOR, and a predetermined function can be used.

  The detection target switching unit 323 corresponds to the detection target switching unit of the present invention, and the detection target control command detected by the control command detection unit 321 in response to generation or transmission of authentication information having the third inspection value. Switching is made among a plurality of predetermined detection target control commands. Therefore, since the timing for detecting the detection control command changes by switching the detection target control command detected by the control command detection unit 321, the change timing by the main control side change unit 322 also changes. An illegal analysis of the change timing can be made even more difficult. Then, the detection target switching unit 323 according to the present embodiment uses the detection target control command set in the detection target control command information as a reference, and sets a plurality of types of detection target control commands indicated by the switching information in a predetermined switching order. And the detected detection target control command is set in the detection target control command information.

  For example, when the switching information indicates two types of control commands, a jackpot start command and a jackpot end command, if the jackpot start command is set in the detection target control command information, the detection target switching unit 323 causes the jackpot start command To the jackpot end command, and the jackpot end command is set in the detection target control command information. Furthermore, since the switching information can be made more complicated by combining the control command related to the jackpot and the control command not related to the jackpot, illegal analysis can be made difficult.

  When the pachinko gaming machine 100 of the present invention uses three types of inspection values for authentication of the main control board 310, the main control board 310 can change these inspection values with the expected value change data, so that the peripheral board 330 acquires the expected value change data from the main control board 310, and changes the expected value corresponding to the inspection value with the expected value change data, so that the main control is performed based on the changed inspection value and expected value. A configuration for performing authentication of the substrate 310 is employed. In addition, since the change by the expected value change data can be switched in conjunction with each of a plurality of predetermined detection target control commands, it is difficult to perform an illegal analysis and the control command is used illegally. Can be expected to be difficult. Therefore, even if the pachinko gaming machine 100 authenticates with one type of authentication information, it can make it difficult to illegally analyze the authentication data, so that security can be improved.

  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 illustrated in FIG. 3, the peripheral board 330 includes a reception unit 331, a peripheral side storage unit 332, an authentication unit 333, a peripheral side control command detection unit 334, a peripheral side change unit 335, a peripheral side detection target switching unit 336, and a specifying unit. 337.

  The receiving unit 331 corresponds to a receiving unit of the present invention, and receives each of the authentication information transmitted by the main control board 310 and a plurality of types of control command data. 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. Then, the receiving unit 331 stores the history of the control command indicated by the received control signal in the peripheral side storage unit 332.

  The peripheral side storage unit 332 corresponds to the expected value storage unit and the peripheral side type information storage unit of the present invention. The peripheral side storage unit 332 has three types of inspection values to be received from the main control board 310 described above, that is, the first inspection value, the second inspection value, and the first inspection value stored in the data storage unit 311 of the main control board 310. Three types of expected values that match each of the three inspection values are stored. The three types of expected values include a first expected value corresponding to the first test value, a second expected value corresponding to the second test value, and a third expected value corresponding to the third test value. Have. As a result, if the inspection value of the authentication data set in the authentication information matches the expected value, the peripheral board 330 can determine that the authentication data is a normal inspection value. If the inspection value and the expected value of the authentication data do not match, it can be determined that the authentication data is not the inspection value. In the present embodiment, description will be made on the premise that the inspection value and the expected value are stored in advance, but the present invention can change the expected value by the above-described expected value changing data. Therefore, the expected value stored in advance may be a value different from the inspection value of the main control board 310, that is, a value that does not match. Note that the third expected value may be stored in the peripheral storage unit 332 in association with the data types described above, similarly to the main control board 310.

  Each of the first expected value and the second expected value is stored in the peripheral storage unit 332 in a one-to-one correspondence with the corresponding (matching) first test value and second test value. ing. Thus, the peripheral unit can specify the data type of the next authentication information determined by the main control unit 201 from the expected value that matches the inspection value received from the main control unit 201.

  The third expected value is stored in the peripheral storage unit 332 in association with the same information as the detection target control command information and the switching information associated with the corresponding (matched) third inspection value. And the peripheral side memory | storage part 332 of this embodiment has memorize | stored the said detection target control command information and switching information. As a result, when the third inspection value received from the main control unit 201 matches the third expected value, the peripheral unit detects the peripheral control command detection described later based on the detection target control command information and the switching information. The detection target control command detected by the unit 334 can be switched.

  The peripheral side storage unit 332 stores peripheral type information indicating the data type of the current authentication information. The peripheral side type information has the same data structure as the type information of the main control board 310 described above, and matches the data type indicated by the type information of the main control board 310 when no fraud has occurred. Therefore, the peripheral board 330 can grasp the data type of the received authentication information in advance by referring to the peripheral side type information before receiving the authentication information from the main control board 310.

  The authentication unit 333 corresponds to the authentication unit of the present invention. When the data type of the peripheral side type information indicates the authentication data, the authentication unit 333 stores the test value that is the authentication data and the peripheral side storage unit 332. The main control board 310 is authenticated by comparing each of the first to third inspection values. And as an example of the authentication method of the authentication part 333, it determines whether any one of a test value and the 1st-3rd expected value corresponds, and the expected value which corresponds in the 1st-3rd expected value is. If it exists, authentication of the main control board 310 is established, and if there is no matching expected value, authentication is not established.

  The peripheral side control command detection unit 334 corresponds to the peripheral side control command detection means of the present invention, and the data type of the peripheral side type information stored in the peripheral side storage unit 332 indicates expected value change data. In addition, in response to the reception of the authentication information having the expected value change data by the receiving unit 331, the detection target that is predetermined from the plurality of types of control commands in the pachinko gaming machine 100 and is the same as the main control board 310 The reception of the detection target control command set in the control command information from the main control board 310 is detected. In other words, the peripheral control command detection unit 334 sets the change timing of the expected value change data received from the main control board 310 when the detection target control command is received from the main control board 310. 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 changing unit 335 corresponds to the peripheral side changing unit of the present invention, and the peripheral side storage unit 332 (expected value storage unit) according to detection of reception of the detection target control command by the peripheral side control command detection unit 334. Changes at least one of the three types of first expected value, second expected value, and third expected value stored based on the expected value changing data included in the received authentication information. To do. The peripheral side changing unit 335 changes the expected value using the same changing method and expected value changing data as the main control side changing unit 320 of the main control board 310. Then, if the data type of the peripheral side type information indicates the expected value change data, the peripheral side changing unit 335 changes the expected value with the incorrect data when receiving the incorrect authentication information. Therefore, since the inspection value of the main control board 310 is changed to a value different from that of the main control board 310, authentication of subsequent authentication information is not established.

  The peripheral side detection target switching unit 336 corresponds to the peripheral side detection target switching unit of the present invention, and is detected by the peripheral side control command detection unit 334 in response to reception by the reception unit 331 of authentication information having the third inspection value. The detection target control command is switched among a plurality of types of detection target control commands as with the main control board 310. Accordingly, since the detection target control command detected by the peripheral side control command detection unit 334 is switched, the detection timing of the detection control command changes, so that the change timing by the peripheral side change unit 335 also changes. Therefore, it is possible to make it more difficult to perform an unauthorized analysis of the change timing. Then, similarly to the main control board 310, the peripheral side detection target switching unit 336 according to the present embodiment uses a plurality of types of detections indicated by the switching information based on the detection target control command set in the detection target control command information. The target control commands are switched in a predetermined switching order, and the switched detection target control command is set in the detection target control command information.

  The specifying unit 337 corresponds to the specifying unit of the present invention. When the authentication of the main control board 310 is established by the authentication unit 333, the data type associated with the expected value that matches the inspection value constituting the authentication data Alternatively, a predetermined data type is specified as the next data type, and the peripheral side type information stored in the peripheral side storage unit 332 is updated to be the specified next data type.

  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 333 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 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 a switching determination unit, a determination unit, a first extraction unit, a second extraction unit, an authentication data generation unit, an expected value change data generation unit in the claims of the first computer, A main control side authentication program for functioning as various means such as authentication information generation means, transmission means, update means, control command detection means, main control side change means, detection target switching means, etc. is stored. In addition, each of the ROMs 242 and 282 of the peripheral board 330 includes the receiving unit, the authenticating unit, the peripheral side control command detecting unit, the peripheral side changing unit, the peripheral side detection target switching unit, the specifying unit, The peripheral side authentication program for functioning as various means such as 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 FIG. 4 to FIG. 9, “send command” means “send a control signal including data (control command data) indicating the command”. The presence or absence of accompanying 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.

  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.

  In the present embodiment, a case will be described in which the above-described detection target control command is a control command related to jackpot in the pachinko gaming machine 100 among the above-described plurality of types of control commands. The control command related to jackpot corresponds to the jackpot related command such as the jackpot reach command, jackpot start command, jackpot command, jackpot end command, etc. described above. In addition, one type or two or more types of detection target control commands described above can be set as detection targets.

(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. As an example of the identification data, there is one type of authentication command different from the control command of the control command data 1001. For example, a value such as hexadecimal 0xA0 is set. Accordingly, the peripheral part can identify whether or not the authentication information 1020 is based on the identification part 1021. The authentication command is differentiated as a command system different from the control command.

  In the data part 1022, either one of the authentication data having any one of the above-described three types of first to third inspection values or the above-described expected value changing data is set. The data unit 1022 of the present embodiment will be described with respect to a case where authentication data or expected value change data is set, but instead, authentication data or expected value change data and other data are stored as data. The embodiment may be set in the unit 1022. Examples of other data include data accompanying an authentication command such as the accompanying data 1002 described above.

(Example of authentication information)
Next, an example of authentication data and expected value change data set in the data portion 1022 of the authentication information 1020 will be described below.

  As shown in FIG. 12, the data type of the authentication information 1020 includes authentication data K1 and expected value change data K2. When the data type of the authentication information 1020 is authentication data K1, the data portion 1022 of the authentication information 1020 contains three types of first inspection value A1, second inspection value A2, and third inspection value A3 (however, A1 Authentication data having any one of ≠ A2 ≠ A3) is set.

  When the data type of the authentication information 1020 is the expected value changing data K2, the expected value changing data having either the correction value C or the coefficient value F is set in the data portion 1022 of the authentication information 1020. The correction value C is a value for changing the predetermined expected value. As the correction value C, for example, the correction value C generated once at the start of the pachinko gaming machine 100, at the time of the first authentication, etc. may be used repeatedly, or the correction value C is irregularly changed by generating a plurality of times. However, in the present embodiment, a case where the correction value Cn (n is an integer) is irregularly changed every time the expected value changing data is generated will be described. When the correction value C is generated a plurality of times, it becomes a value for changing the common inspection value and expected value every time it is generated.

  The coefficient value F is a value for changing the expected value changed last time. That is, the coefficient value F is a value for accumulating and changing the inspection value and the expected value every time the inspection value and the expected value are changed. As with the correction value C, the coefficient value F generated once may be used repeatedly, or may be generated a plurality of times and the coefficient value Fn (n is an integer) may be changed irregularly.

  Next, an example of correspondence between the three types of inspection values A, the three types of expected values B, the data types K1 and K2 of the authentication information 1020, and the switching information H will be described.

  First, in the pachinko gaming machine 100, as shown in FIG. 13, when three types of first to third inspection values A1 to A3 for the main control board 310 are set, the three types of first to third inspections. First to third expected values B1 to B3 corresponding to the values A1 to A3 are set for the peripheral board 330. Then, the data types K1 and K2 of the authentication information 1020 shown in FIG. 12 are allocated to each of the first inspection value A1, the second inspection value A2, the first expected value B1, and the second expected value B2 of the three types. . The main control board 310 stores the first inspection value A1 and the second inspection value A2 in association with the data types K1 and K2 of the authentication information 1020. The peripheral board 330 stores the first expected value B1 and the second expected value B2 in association with the data types K1 and K2 of the authentication information 1020 that are the same as the corresponding first inspection value A1 and second inspection value A2. .

  Further, the switching of the detection target control command described above is assigned to the third inspection value A3 and the third expected value B3. Then, the main control unit board 310 detects the timing for generating or transmitting the authentication information 1020 having the third inspection value A3 as the switching timing of the detection target control command. On the other hand, the peripheral board 330 detects the timing of receiving the authentication information 1020 having the third inspection value A3 that matches the third expected value B3 as the switching timing of the detection target control command. The main control board 310 of the present embodiment stores the switching information H described above in association with the third inspection value A3. On the other hand, the peripheral board 330 stores the same switching information H as that of the main control board 330 in association with the third expected value B3. The main control board 310 stores the detection target control command information storing data indicating the detection target control command in association with the third inspection value A3, and the peripheral board 330 stores the detection target control value at the third expected value B3. The target control command information is stored.

  As described above, the switching information H is configured to indicate the switching order of a plurality of detection target control commands. In the present embodiment, in order to simplify the description, a case of a switching method in which two control commands of a jackpot start command and a jackpot end command are switched in that order will be described. For example, when starting the pachinko gaming machine 100, the main control board 310 sets the jackpot start command first indicated by the switching information H to the detection target control command information at a predetermined arbitrary timing, etc. When the switching timing is detected, the switching information H sets the next jackpot end command shown in the detection target control command information, thereby switching a plurality of detection target control commands. Similarly thereafter, the main control board 310 switches the detection target control command every time the switching timing is detected. On the other hand, the peripheral board 330 refers to the switching information H in the same manner as the main control board 310, and switches the detection target control command every time the switching timing is detected.

  Since the first to third inspection values A1 to A3 and the first to third expected values B1 to 3 are changed by the expected value changing data, the correspondence between the data types K1 and K2 and the switching information H is as follows. For example, it is possible to adopt various different embodiments such as updating the association every time it is changed, associating the changed value, and the initial value with each piece of information.

  Next, a modification example using the correction value Cn described above will be described. In pachinko gaming machine 100, first to third inspection values A1 to A1 correspond to first to third expected values B1 to B3 (A1 = B1, A2 = B2, A3 = B3), n is an integer, and change method Is assumed to be “+”.

  In the first change, when the main control board 310 generates the correction value C1, the main control board 310 transmits the correction value C1 to the peripheral board 330, and in response to detection of the change switching timing, the first inspection value A1 that is an initial value. Is changed by the correction value C1, the first inspection value A1 + C1, the second inspection value A2 which is the initial value is changed by the correction value C1, the second inspection value A2 + C1, and the third inspection value A3 which is the initial value is the correction value C1. To change to the third inspection value A3 + C1. On the other hand, the peripheral board 330 receives the correction value C1 from the main control board 310, and changes the first expected value B1, which is the initial value, by the correction value C1 in response to the detection of the change switching timing. B1 + C1, the second expected value B2 that is the initial value is changed by the correction value C1, and the second expected value B2 + C1, and the third expected value B3 that is the initial value is changed by the correction value C1 to be the third expected value B3 + C1. Therefore, since the matched inspection value and the expected value are changed with the same correction value, the first inspection value A1 + C1, the second inspection value A2 + C1, the third inspection value A3 + C1 of the main control board 310 and the first expectation of the peripheral board 330. When each of the values B1 + C1, the second expected value B2 + C1, and the third expected value B3 + C1 coincides, the peripheral board 330 has the inspection values A1 + C1, A2 + C1, A3 + C1 of the authentication information received from the main control board 310. Therefore, authentication of the main control board 310 can be established.

  In the second change, when the main control board 310 generates a correction value C2 that is different from the correction value C1, the main control board 310 transmits the correction value C2 to the peripheral board 330, and at an initial value according to the detection of the change switching timing. A first inspection value A1 is changed by a correction value C2 to change a first inspection value A1 + C2, a second inspection value A2 that is an initial value is changed by a correction value C2, a second inspection value A2 + C2, and a third inspection that is an initial value. The value A3 is changed with the correction value C2 to obtain a third inspection value A3 + C2. On the other hand, the peripheral board 330 receives the correction value C2 from the main control board 310, and changes the first expected value B1, which is the initial value, with the correction value C2 in response to the detection of the change switching timing. B1 + C2, the second expected value B2 that is the initial value is changed with the correction value C2, and the second expected value B2 + C2, and the third expected value B3 that is the initial value is changed with the correction value C2 to be the third expected value B3 + C2. Therefore, since the matched inspection value and the expected value are changed with the same correction value, the first inspection value A1 + C2, the second inspection value A2 + C2, the third inspection value A3 + C2 of the main control board 310, and the first expectation of the peripheral board 330. When the value B1 + C2, the second expected value B2 + C2, and the third expected value B3 + C2 coincide with each other, the peripheral board 330 has the inspection values A1 + C2, A2 + C2, A3 + C2 of the authentication information received from the main control board 310 being normal. Therefore, authentication of the main control board 310 can be established. The same change is made for the third and subsequent changes.

  Next, when the first inspection value A1 of the initial value on the main control board 310 and the first expected value B0 of the initial value on the peripheral board 330 do not match (A1 ≠ B0), they are changed by the correction value Cn. A modification example will be described. In order to simplify the description, the description is limited to the case where only the first inspection value A1 and the first expected values B0 and B1 are changed.

  In the first change, the main control board 310 generates a difference correction value C0 (= A1-B0) between the first inspection value A1 and the first expected value B0 stored in advance in the data storage unit 311 or the like. The difference correction value C0 is transmitted to the peripheral board 330. On the other hand, when the peripheral board 330 receives the difference correction value C0, the first expected value B0, which is the initial value, is changed to the first expected value B1 (= B0 + C0) by the difference correction value C0. As a result, the first expected value B1 is changed to a value that matches the first inspection value A1 of the main control board 310.

  In the second change, when the main control board 310 generates the correction value C1, the main control board 310 transmits the correction value C1 to the peripheral board 330, and in response to the detection of the change switching timing, the first inspection value A1 that is an initial value. Is changed by the correction value C1 to be the first inspection value A1 + C1. On the other hand, the peripheral board 330 receives the correction value C1 from the main control board 310, and changes the first expected value B1 changed last time with the correction value C1 in response to the detection of the change switching timing, thereby changing the first expected value B1 + C1. And Therefore, since the matched first inspection value A1 and first expected value B1 are changed by the same correction value C1, the first inspection value A1 + C1 of the main control board 310 and the first expected value B1 + C1 of the peripheral board 330 are equal. If it does, the peripheral board 330 can determine that the first inspection value A1 + C1 of the authentication information received from the main control board 310 is authentic, so that the authentication of the main control board 310 can be established. The third and subsequent changes are also made in the same manner as the second change.

  Next, when the first inspection value A0 of the initial value on the main control board 310 and the first expected value B0 of the initial value on the peripheral board 330 do not match (A0 ≠ B0), they are changed by the correction value Cn. Another modification will be described. In order to simplify the description, the description is limited to the case where only the first inspection value and the first expected value are changed.

  In the first change, the main control board 310 generates a difference correction value C0 (= A0−B0) between the first inspection value A0 and the first expected value B0 stored in advance in the data storage unit 311 or the like. The difference correction value C0 is stored in the data storage unit 311 or the like, and the initial first inspection value A0 is set as the first inspection value A1. The peripheral board 330 sets the initial first expected value B0 as the expected value B1. For example, when the main control board 310 adds the difference correction value C0 and the current value to create the current correction value C1, the main control board 310 transmits the correction value C1 to the peripheral board 330 and detects the change switching timing. Accordingly, the first inspection value A1, which is the initial value, is changed by the correction value C1 to obtain the first inspection value A1 + C1. On the other hand, the peripheral board 330 receives the correction value C1 from the main control board 310, and corrects the first expected value B1 with the correction value C1 to be the first expected value B1 + C1 in response to detection of the change switching timing. As a result, the main control board 310 generates a correction value C1 that absorbs the difference between the first inspection value A1 and the first expected value B0 and transmits it to the peripheral board 330, and the peripheral board 330 uses the first expected value B0 as it is. Correction and authentication will be sufficient.

  Next, using the coefficient value Fn described above, the previous first inspection value A1 (n−1), second inspection value A2 (n−1), third inspection value A3 (n−1), and first expectation. A modification example in which each of the value B1 (n−1), the second expected value B2 (n−1), and the third expected value B3 (n−1) is changed will be described. In the pachinko gaming machine 100, the first to third inspection values A1 to 3 correspond to the first to third expected values B1 to 3 (A1n = B1n, A2n = B2n, A3n = B3n), n is an integer, and the change method Is assumed to be “*”.

  In the first change, when the main control board 310 generates the coefficient value F1, the main control board 310 transmits the coefficient value F1 to the peripheral board 330, and in response to detection of the change switching timing, the first inspection value A11 that is an initial value. The first inspection value A12 is changed by the coefficient value F1, the second inspection value A21 which is the initial value is changed by the coefficient value F1, the second inspection value A22 and the third inspection value A31 which is the initial value is the coefficient value F1. To change to the third inspection value A32. On the other hand, the peripheral board 330 receives the coefficient value F1 from the main control board 310, and changes the first expected value B11, which is the initial value, by the coefficient value F1 in response to the detection of the change switching timing. B12, the second expected value B21, which is the initial value, is changed by the coefficient value F1, and the second expected value B22 is changed, and the third expected value B31, which is the initial value, is changed by the coefficient value F1, to be the third expected value B32. Therefore, since the matched inspection value and the expected value are changed by the same coefficient value, the first inspection value A12, the second inspection value A22, the third inspection value A32 of the main control board 310 and the first expectation of the peripheral board 330 are changed. When the value B12, the second expected value B22, and the third expected value B32 match, the peripheral board 330 receives the first inspection value A12, the second inspection value A22, the second inspection value of the authentication information received from the main control board 310. Since the three inspection values A32 can be determined to be regular, the authentication of the main control board 310 can be established.

  In the second change, when the main control board 310 generates the coefficient value F2 (F1 ≠ F2), the main control board 310 transmits the coefficient value F2 to the peripheral board 330, and in response to detection of the change switching timing, The 1 inspection value A12, the 2nd inspection value A22, and the 3rd inspection value A32 are changed by the coefficient value F2 to obtain the first inspection value A13, the second inspection value A23, and the third inspection value A33. On the other hand, the peripheral board 330 receives the coefficient value F2 from the main control board 310, and receives the first expected value B12, the second expected value B22, and the third expected value B32 that were changed last time in response to the detection of the change switching timing. The coefficient value F2 is changed to a first expected value B13, a second expected value B23, and a third expected value B33. Therefore, since the previously changed inspection value and the expected value are changed with the same coefficient value, the first inspection value A13, the second inspection value A23, the third inspection value A33 of the main control board 310 and the first of the peripheral board 330 are changed. When the expected value B13, the second expected value B23, and the third expected value B33 match, the peripheral board 330 receives the first test value A13, the second test value A23, and the authentication information received from the main control board 310. Since the third inspection value A33 can be determined to be regular, the authentication of the main control board 310 can be established. The third and subsequent changes are also made in the same manner as the second change.

  In the present embodiment, when the initial test value and the expected value are different values, the main control board 310 stores both the test value and the expected value. A case has been described in which expected value change data that absorbs the difference between a value and an expected value is generated. Instead, the main control board 310 stores in advance the difference data between the inspection value A and the expected value B in the data storage unit 311 and the like, and the correction value Cn and the coefficient value Fn described above based on the difference data. It can also be set as the embodiment which produces | generates. With such an embodiment, the main control board 310 can eliminate the need to store the expected value B of the peripheral board 330.

(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 the flowchart of FIG.

  When the power of the pachinko gaming machine 100 is turned on (turned on), the main control unit 201 executes an authenticated process shown in FIG. 14 and determines whether or not it is a predetermined authentication timing in step S1201. If the main control unit 201 determines that it is not the authentication timing (S1201: No), the main control unit 201 proceeds to the process of step S1222. On the other hand, if the main control unit 201 determines that it is the authentication timing (S1201: Yes), the process proceeds to step S1202.

  In step S1202, the main control unit 201 determines whether to switch different data types based on, for example, a random number generation result, and determines whether to switch data types based on the determination result. When the main control unit 201 determines that the data type is to be switched (S1202: Yes), in step S1203, the main control unit 201 sets the next data type set in the type information of the data storage unit 311 as the current data type, and then The process proceeds to step S1204. When the next data type is not set in the type information, that is, in the first process, the initial data type predetermined as an initial value in the pachinko gaming machine 100 is set as the current data type. In the following description, it is assumed that the initial data type is the data type K1 that is authentication data.

  In step S1204, the main control unit 201 determines whether or not the current data type is authentication data. When the data type is not the authentication data, that is, the expected value change data (S1204: No), the main control unit 201 proceeds to the process of step S1205. In step S1205, the main control unit 201 determines whether the detection target control command is being monitored based on whether monitoring start is set in the data storage unit 311 or the like. If the main control unit 201 determines that monitoring is in progress (S1205: Yes), since expected value change data has already been generated, in step S1206, the previous expected value change data, that is, data storage. The expected value change data stored in the unit 311 and the like is stored for generating the authentication information 1020, and then the process proceeds to step S1209. On the other hand, if the main control unit 201 determines that monitoring is not being performed (S1205: No), the process proceeds to step S1207.

  In step S1207, the main control unit 201 randomly generates expected value change data for changing the inspection value and the expected value using a predetermined generation method, and the generated expected value change data is authenticated. The data is stored in the data storage unit 311 or the like for generation of 1020, and then the process proceeds to step S1208. An example of a method for generating expected value change data is to generate the expected value change data by using the generation method using a random number or a pattern table. In step S1208, the main control unit 201 causes monitoring target control command monitoring processing shown in FIG. 15 described later to function, thereby starting monitoring transmission of the detection target control command indicated by the detection target control command information. Thereafter, the process proceeds to step S1209.

  In step S1209, the main control unit 201 determines a data type predetermined for generating expected value change data as the next data type and stores it in the RAM 213 or the like, and then proceeds to the processing of step S1218. The predetermined data type is determined in advance between the main control board 310 and the peripheral board 330.

  On the other hand, if the main control unit 201 determines in step S1204 that the data type is authentication data (S1204: Yes), in step S1210, the main control unit 201 generates the next time from the data type of the authentication data and the expected value change data. The data type of the authentication information is randomly determined and stored in the RAM 213 or the like, and then the process proceeds to step S1211.

  In step S1211, the main control unit 201 extracts the inspection value corresponding to the next data type determined in step S1210 from the first inspection value A1 or the second inspection value A2, and stores it in the RAM 213 or the like, and in step S1212. Then, authentication data having the extracted inspection value is generated and stored in the RAM 213 or the like for generation of the authentication information 1020, and then the process proceeds to step S1218. As a result, authentication data having one of the first inspection value A1 and the second inspection value A2 is created.

  If the main control unit 201 determines in step S1202 that the data type is not to be switched (S1202: No), in step S1213, the third inspection value A3 is extracted from the three types of inspection values and stored in the RAM 213 or the like in time series. And then the process proceeds to step S1214. In step S1214, the main control unit 201 generates authentication data having the extracted third inspection value A3 and stores it in the RAM 213 or the like, and then proceeds to the processing of step S1215. As a result, authentication data having the third inspection value A3 is created.

  In step S1215, the main control unit 201 determines whether or not the detection target control command is being monitored based on whether or not monitoring start is set in the data storage unit 311 or the like. If the main control unit 201 determines that monitoring is in progress (S1215: Yes), the process proceeds to step S1217 because expected value change data has already been generated. On the other hand, if the main control unit 201 determines that the monitoring is not being performed (S1215: No), in step S1216, a plurality of types indicated by the switching information H based on the detection target control command indicated by the detection target control command information. The detection target control command is switched to the detection target control command next to the reference detection target control command and stored in the detection target control command information, and then the process proceeds to step S1217. In step S1217, the main control unit 201 diverts the next data type set in the type information of the data storage unit 311 and then proceeds to the process of step S1218.

  In step S1218, the main control unit 201 sets a predetermined authentication command in the identification unit 1021 of the authentication information 1020, sets the generated authentication data or expected value change data in the data unit 1022, and sets the authentication information. 1020 is generated, the generated authentication information 1020 is stored in the data storage unit 311 or the like, and then the process proceeds to step S1219.

  In step S1219, the main control unit 201 encrypts the generated authentication information 1020 with a predetermined encryption method with the peripheral unit, and in step S1220, based on each of the encrypted authentication information 1020. Then, an authentication information signal is generated and transmitted from the transmission unit 317 to the peripheral unit, and then the process proceeds to step S1221. If encryption is not required between the main control unit 201 and the peripheral unit, the processing in step S1219 is deleted and the authentication information 1020 is transmitted to the peripheral unit as it is. In step S1221, the main control unit 201 updates the type information in the data storage unit 311 to indicate the next data type determined in step S1209 or step S1210, and then proceeds to the process of step S1222.

  In step S1222, 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 (S1222: 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 (S1222: Yes), the process according to this flowchart ends.

  Next, an example of the detection target control command monitoring process by the CPU 211 (first computer) of the main control unit 201 will be described with reference to the flowchart of FIG. In this embodiment, the case where the CPU 211 executes the detection target control command monitoring process and performs the above-described authenticated process and the detection target control command monitoring process in parallel will be described. A configuration realized by hardware can also be adopted.

  When executing the detection target control command monitoring process shown in FIG. 15, the main control unit 201 sets monitoring start in the data storage unit 311 and the like in step S1301, and transmits it from the main control unit 201 to the peripheral unit in step S1302. It is determined whether or not the control command is a detection target control command set in the detection target control command information, for example, a jackpot related command. If the main control unit 201 determines that the command is not a detection target control command (S1302: No), the main control unit 201 proceeds to the process of step S1303.

  In step S1303, 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 (S1303: No), the main control unit 201 returns to the process of step S1302, and repeats a series of processes. On the other hand, when the main control unit 201 determines that the power is turned off (S1303: Yes), the process according to this flowchart ends.

  If the main control unit 201 determines in step 1302 that the command is a detection target control command (S1302: Yes), based on the expected value change data stored in the data storage unit 311 in step S1304 in advance. At least one of the defined three types of first inspection value A1, second inspection value A2, and third inspection value A3 is changed by the above-described change method, and monitoring is terminated in the data storage unit 311 or the like in step S1305 Is set, and the expected value changing data used for the change is deleted, and then the processing according to this flowchart is terminated.

  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 executing the authentication side processing shown in FIG. 16, the peripheral unit determines whether or not authentication information (authentication information signal) 1020 has been received from the main control unit 201 by the receiving unit 331 in step S1401. If the peripheral unit determines that the authentication information 1020 has not been received (S1401: No), the process proceeds to step S1417. On the other hand, if it is determined that the authentication information 1020 has been received (S1401: Yes), the peripheral unit decrypts the received authentication information 1020 with a decryption method corresponding to the encryption method of the main control unit 201, and then step S1402 Proceed to the process. If encryption is not required between the main control unit 201 and the peripheral unit, the decryption process in step S1401 is deleted.

  In step S1402, the peripheral unit determines whether the peripheral type information in the peripheral storage unit 332 indicates authentication data. If it is determined that the peripheral portion indicates authentication data (S1402: Yes), in step S1403, the authentication data is extracted from the data portion 1022 of the received authentication information 1020 and stored in the peripheral side storage portion 332 or the like. Then, the process proceeds to step S1404.

  In step S1404, the peripheral unit compares the authentication data with each of the three types of first expected value B1, second expected value B2, and third expected value B3 stored in the peripheral storage unit 332. Then, it is determined whether or not it matches any expected value. When it is determined that the peripheral portion matches the expected value (S1404: Yes), in step S1405, authentication for the main control unit 201 is established, and the inspection values are stored in the RAM 243 or the like in time series, Thereafter, the process proceeds to step S1406.

  In step S1406, the peripheral unit determines whether or not the authentication data is the first inspection value A1 or the second inspection value A2 based on whether or not it matches the first expected value B1 or the second expected value B2. judge. When it is determined that the peripheral portion is the first inspection value A1 or the second inspection value A2 (S1406: Yes), in step S1407, the peripheral portion is associated with the expected value that matches the first inspection value A1 or the second inspection value A2. The specified data type is specified, and the specified data type is set as the next data type in the peripheral side type information of the peripheral side storage unit 332, and then the process proceeds to step S1417.

  If it is determined in step S1406 that the peripheral portion is not the first inspection value A1 or the second inspection value A2 (S1406: No), that is, if it is the third inspection value, the peripheral side memory is stored in step S1408. Based on whether monitoring start is set in the unit 332 or the like, it is determined whether or not the detection target control command is being monitored. If it is determined that the peripheral portion is being monitored (S1408: Yes), the process proceeds to step S1410. On the other hand, when it is determined that the peripheral portion is not being monitored (S1408: No), in step S1409, a plurality of types of detections indicated by the switching information H based on the detection target control command indicated by the detection target control command information. The target control command is switched to the detection target control command next to the reference detection target control command and stored in the detection target control command information, and then the process proceeds to step S1410. In step S1410, the peripheral unit diverts the next data type set in the peripheral side type information of the peripheral side storage unit 332, and then proceeds to the process of step S1417.

  On the other hand, if it is determined in step S1404 that the peripheral portion does not match the expected value (S1404: No), authentication in the main control unit 201 is not established in step S1411, and in step S1412, for example, the speaker 262 (FIG. 2). The notification signal is output from the reference) and the processing according to this flowchart is terminated.

  Further, when it is determined in step S1402 that the peripheral side type information does not indicate authentication data (S1402: No), that is, in the case where the peripheral portion indicates expected value change data, in step S1413, the peripheral side Based on whether monitoring start is set in the storage unit 332 or the like, it is determined whether or not the detection target control command is being monitored. If it is determined that the peripheral portion is being monitored (S1413: Yes), the processing proceeds to step S1416. On the other hand, if it is determined that the peripheral portion is not being monitored (S1413: No), in step S1414, the expected value change data is extracted from the data portion 1022 of the received authentication information 1020, and the peripheral side storage portion 332 and the like. In step S1415, the monitoring of the detection target control command indicated by the detection target control command information from the main control unit 201 is started by causing a peripheral side command monitoring process shown in FIG. 17 described later to function. Thereafter, the process proceeds to step S1416. Then, in step S 1416, the peripheral unit specifies a data type predetermined with the main control unit 201 as the next data type, and sets the specified data type as the next data type in the peripheral side storage unit 332. The peripheral type information is set, and then the process proceeds to step S1417.

  In step S1417, 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 (S1417: No), the processing returns to step S1401, and a series of processing is repeated. On the other hand, when it is determined that the power source is turned off (S1417: Yes), the peripheral unit ends the processing according to this flowchart.

  Next, an example of peripheral side command monitoring processing by the peripheral CPUs 241 and 281 (second computer) will be described with reference to the flowchart of FIG. In the present embodiment, as with the main control unit 201, the peripheral side command monitoring process is executed by one of the CPUs 241 and 281 and the above-described authentication side process and the peripheral side command monitoring process are performed in parallel. As will be described, instead of this, a configuration realized by other hardware may be employed.

  When the peripheral unit executes the peripheral side command monitoring process shown in FIG. 17, in step S1501, the monitoring start is set in the peripheral side storage unit 332 and the like, and in step S1502, the reception unit 331 receives the normal control from the main control unit 201. It is determined whether a control command is received based on whether a control signal is received. When it is determined that the peripheral unit has not received the control command (S1502: No), the process proceeds to step S1506. On the other hand, if it is determined that the peripheral part has received the control command (S1502: Yes), the process proceeds to step S1503.

  In step S1503, the peripheral unit determines whether or not the received control command is a detection target control command that is predetermined with the main control unit 201 and set in the detection target control command information. When it is determined that the peripheral portion is the detection target control command (S1503: Yes), in step S1504, based on the expected value changing data, the first expected value B1, the second expected value B2, At least one of the third expected values B3 is changed by the change method described above in the same manner as the main control unit 201, and in step S1505, the monitoring end is set in the peripheral storage unit 332 and the like, and the expectation used for the change The value change data is deleted, and then the processing according to this flowchart is terminated.

  If it is determined in step S1503 that the command is not a detection target control command (S1503: No), the peripheral unit determines in step S1506 whether the pachinko gaming machine 100 is powered off. If it is determined that the power source is not turned off (S1506: No), the peripheral unit returns to the process of step S1502 and repeats a series of processes. On the other hand, when it is determined that the power source is turned off (S1506: Yes), the peripheral unit ends the process according to this flowchart.

(Example of authentication processing procedure using authentication information)
Next, when the data types K1 and K2 shown in FIG. 12 are switched, the first to third inspection values and the first to third expected values are changed, and the change timing is changed to authenticate the main control board 310. An example of the procedure in the pachinko gaming machine 100 will be described with reference to the drawings of FIGS. In the present embodiment, it is assumed that the switching information H indicates that two types of detection target control commands, a jackpot start command and a jackpot end command, are switched in that order.

  In FIG. 18, when the main control board 310, which is the person to be authenticated, determines the data type switching and at random (S1601), it sets the predetermined data type K1 (S1602). The main control board 310 randomly determines the authentication information 1020 to be generated next time from the data types K1 and K2 as the data type K2 and updates the type information (S1603), and as shown in FIG. 13, the data type K2 Data for authentication of the second inspection value A2 associated with is generated (S1604). Then, the main control board 310 generates authentication information 1020 (A2) having the authentication data, and transmits the authentication information 1020 (A2) to the peripheral board 330 (S1605).

  On the other hand, the peripheral board 330 sets a predetermined data type K1 for this time (S1651), and receives authentication information 1020 (A2) from the main control board 310 (S1652), this time indicates authentication data. Therefore, it is determined whether or not the authentication data in the data portion 1022 of the authentication information 1020 (A2) matches the three types of expected values stored in the peripheral storage portion 332, thereby authenticating the main control board 310. Is performed (S1653). When the authentication is established, the peripheral substrate 330 corresponds to the second expected value B2 because the authentication data is the second inspection value A2, and therefore coincides with the second expected value B2 of the peripheral storage unit 332. The attached data type K2 is identified as the next data type, and the peripheral side type information of the peripheral side storage unit 332 is updated to indicate the data type K2 (S1654).

  Subsequently, when the main control board 310 determines at random the switching of the data type (S1606), the main control board 310 sets the data type K2 indicated by the type information in the data storage unit 311 as the current data type (S1607). The main control board 310 randomly determines the authentication information 1020 to be generated next time from the data types K1 and K2 as the data type K1, and updates the type information (S1608). The main control board 310 randomly generates the expected value change data C1 for changing the inspection value and the expected value by a predetermined generation method (S1609), and the authentication information 1020 having the expected value change data. (C1) is generated, and the authentication information 1020 (C1) is transmitted to the peripheral board 330 (S1610). When the main control board 310 detects the transmission of the jackpot start command, which is the detection target control command indicated by the detection target control command information in the data storage unit 311, to the peripheral board 330 (S 1611), the main control board 310 includes the expected value change data C 1. Based on the above-described changing method, the three types of inspection values are changed (S1612). In the present embodiment, it is assumed that the change method in the pachinko gaming machine 100 is “+”, and the main control board 310 has the first inspection value A1 + C1, the second inspection value A2 + C1, and the third inspection value A3 + C1, respectively. It has been changed.

  On the other hand, the peripheral board 330 sets the current data type K2 based on the peripheral side type information in the peripheral side storage unit 332 (S1655) and receives the authentication information 1020 (C1) from the main control board 310. Since the value change data is shown, the expected value change data C1 of the data portion 1022 of the authentication information 1020 (C1) is stored in the peripheral storage unit 332 or the like (S1656). The peripheral board 330 identifies a data type predetermined for generating expected value change data as the next data type, and updates the peripheral side type information of the peripheral side storage unit 332 to indicate this data type K1. (S1657). When the peripheral board 330 detects the reception of the jackpot start command, which is the detection target control command indicated by the detection target control command information in the peripheral-side storage unit 332, from the main control board 310 (S1658), the expected value change data C1 Based on the above, the three types of expected values in the peripheral storage unit 332 are changed by the above-described changing method (S1659). As a result, the peripheral board 330 is changed to the first expected value B1 + C1, the second expected value B2 + C1, and the third expected value B3 + C1 that match the inspection values of the main control board 310, respectively.

  Subsequently, when the main control board 310 randomly determines that the data type is not switched (S1613), the main control board 310 diverts the data type K1 indicated by the type information in the data storage unit 311 as the next data type (S1614). The main control board 310 generates authentication data for the third inspection value A3 + C1 extracted from the data storage unit 311 (S1615). Then, the main control board 310 generates authentication information 1020 (A3 + C1) having the authentication data, and transmits the authentication information 1020 (A3 + C1) to the peripheral board 330 (S1616). Then, the main control board 310 switches the detection target control command from the jackpot start command to the jackpot end command based on the switching information H described above and sets the detection target control command information in the detection target control command information (S1617).

  On the other hand, the peripheral board 330 sets the current data type K1 based on the peripheral side type information in the peripheral side storage unit 332 (S1660), and receives the authentication information 1020 (A3 + C1) from the main control board 310 (S1661). Since authentication data is shown this time, whether or not the authentication data A3 + C1 of the data portion 1022 of the authentication information 1020 (A3 + C1) matches the three types of expected values stored in the peripheral storage unit 332 And the main control board 310 is authenticated (S1662). When the authentication is established, the peripheral substrate 330 uses the data type K1 indicated by the peripheral side type information in the peripheral side storage unit 332 as the next data type because the authentication data is the third inspection value A3 + C1 ( S1663). Then, similarly to the main control board 310, the peripheral board 330 switches the detection target control command from the jackpot start command to the jackpot end command based on the switching information H described above, and sets the detection target control command information in the detection target control command information (S1664). .

  Subsequently, in FIG. 19, when the main control board 310 determines the data type switching and at random (S1618), the data type K1 indicated by the type information in the data storage unit 311 is set as the current data type (S1619). . The main control board 310 randomly determines the authentication information 1020 to be generated next time from the data types K1 and K2 as the data type K1, and updates the type information (S1620). The main control board 310 generates authentication data for the inspection value (A1 + C1) associated with the data type K1 (S1621). Then, the main control board 310 generates authentication information 1020 (A1 + C1) having the authentication data, and transmits the authentication information 1020 (A1 + C1) to the peripheral board 330 (S1622).

  On the other hand, the peripheral board 330 sets the current data type K1 based on the peripheral side type information in the peripheral side storage unit 332 (S1665), and receives the authentication information 1020 (A1 + C1) from the main control board 310 (S1466). Since authentication data is shown this time, it is determined whether or not the authentication data in the data portion 1022 of the authentication information 1020 (A1 + C1) matches the three types of expected values stored in the peripheral storage unit 332. The main control board 310 is authenticated by making a determination (S1667). When the authentication is established, the peripheral substrate 330 corresponds to the first expected value B1 + C1 because the authentication data is the first inspection value A1 + C1 and matches the first expected value B1 + C1 of the peripheral storage unit 332. The attached data type K1 is specified as the next data type, and the peripheral side type information in the peripheral side storage unit 332 is updated to indicate the data type K1 (S1668).

  Subsequently, when the main control board 310 determines at random the switching of the data type (S1623), the main control board 310 sets the data type K1 indicated by the type information in the data storage unit 311 as the current data type (S1624). The main control board 310 randomly determines the authentication information 1020 to be generated next time as the data type K2 from the data types K1 and K2, and updates the type information (S1625). The main control board 310 generates authentication data for the inspection value (A2 + C1) associated with the data type K2 (S1626). Then, the main control board 310 generates authentication information 1020 (A2 + C1) having the authentication data, and transmits the authentication information 1020 (A2 + C1) to the peripheral board 330 (S1627).

  On the other hand, the peripheral board 330 sets the current data type K1 based on the peripheral side type information in the peripheral side storage unit 332 (S1669), and receives the authentication information 1020 (A2 + C1) from the main control board 310 (S1670). Since authentication data is shown this time, it is determined whether or not the authentication data in the data portion 1022 of the authentication information 1020 (A2 + C1) matches the three types of expected values stored in the peripheral storage unit 332. The main control board 310 is authenticated by making a determination (S1671). Then, since the authentication data is the second inspection value A2 + C1 when the authentication is established, the peripheral board 330 matches the second expected value B2 + C1 of the peripheral storage unit 332, and therefore corresponds to the second expected value B2 + C1. The attached data type K2 is identified as the next data type, and the peripheral side type information of the peripheral side storage unit 332 is updated to indicate the data type K2 (S1672).

  Subsequently, when the main control board 310 randomly determines the switching of the data type (S1628), the main control board 310 sets the data type K2 indicated by the type information in the data storage unit 311 as the current data type (S1629). The main control board 310 randomly determines the authentication information 1020 to be generated next time as the data type K1 from the data types K1 and K2, and updates the type information (S1630). The main control board 310 randomly generates expected value change data C2 for changing the inspection value and the expected value by a predetermined generation method (S1631), and authentication information 1020 having the expected value change data. (C2) is generated, and the authentication information 1020 (C2) is transmitted to the peripheral board 330 (S1632). When the main control board 310 detects transmission of the jackpot end command, which is the detection target control command indicated by the detection target control command information in the data storage unit 311, to the peripheral board 330 (S 1633), the main control board 310 stores the expected value change data C 2. Based on the above-described changing method, three types of inspection values are changed (S1634). As a result, the main control board 310 is changed to the first inspection value A1 + C2, the second inspection value A2 + C2, and the third inspection value A3 + C2.

  On the other hand, the peripheral board 330 sets the current data type K2 based on the peripheral side type information in the peripheral side storage unit 332 (S1673), and is expected this time when receiving the authentication information 1020 (C2) from the main control board 310. Since the value change data is shown, the expected value change data C2 of the data portion 1022 of the authentication information 1020 (C2) is stored in the peripheral storage unit 332 or the like (S1674). The peripheral board 330 specifies the data type K1 predetermined for generating the expected value change data as the next data type, and uses the peripheral side type information of the peripheral storage unit 332 to indicate the data type K1. Update (S1675). When the peripheral board 330 detects reception of the jackpot end command, which is the detection target control command indicated by the detection target control command information in the peripheral storage unit 332, from the main control board 310 (S1676), the expected value changing data C1 Based on the above, the three types of expected values in the peripheral storage unit 332 are changed by the above-described changing method (S1677). Note that the peripheral board 330 has been changed to the first expected value B1 + C2, the second expected value B2 + C2, and the third expected value B3 + C2 that match the inspection values of the main control board 310, respectively. Thereafter, the same authentication process as described above is performed.

(Example of change procedure using expected value change data)
Next, an example of a changing procedure when each of the main control board 310 and the peripheral board 330 changes the inspection value and the expected value using the expected value changing data will be described with reference to the drawing of FIG.

  In FIG. 20, when generating the expected value change data, the main control board 310 stores the expected value change data in the data storage unit 311 and the like and transmits it to the peripheral board 330, which is indicated by the detection target control command information. Monitoring of the transmission of the detection target command to the peripheral board 330 is started (S1701). On the other hand, the peripheral board 330 temporarily stores the expected value change data received from the main control board 310 in the peripheral storage unit 332 and the like, and starts monitoring the reception of the detection target command indicated by the detection target control command information (S1751). ). Thereafter, when the main control board 310 transmits a non-detection target control command to the peripheral board 330 to control the peripheral board 330, the inspection value is not changed because the command is not a detection target control command (S1702). . When the peripheral board 330 receives the non-detection target control command from the main control board 310, the peripheral board 330 performs a predetermined process corresponding to the command and does not change the expected value (S1752). Then, when the main control board 310 transmits a detection target control command to the peripheral board 330 in order to control the peripheral board 330 (S1703), the command is a detection target control command and is stored in the data storage unit 311 or the like. Each of the first to third inspection values is changed with the expected value changing data (S1704). When the peripheral board 330 receives the detection target control command from the main control board 310, the peripheral board 330 performs a predetermined process corresponding to the command, and performs the first process based on the expected value change data stored in the peripheral side storage unit 332 and the like. 1 to 3 expected values are changed (S1753). Thereby, both the inspection value and the expected value are changed according to the generation of the detection target control command.

  When the main control board 310 generates authentication data having the third inspection value A3, the main control board 310 generates authentication information 1020 (A3) having the authentication data and transmits it to the peripheral board 330 (S1705). The main control board 310 switches the detection target control command based on the switching information H (S1706). On the other hand, the peripheral board 330 authenticates the main control board 310 based on the third inspection value A3 of the authentication information 1020 (A3) received from the main control board 310 (S1754). Similar to the main control board 310, the peripheral board 330 switches the detection target control command based on the switching information H (S1755).

  Subsequently, when generating the first expected value change data, the main control board 310 stores the first expected value change data in the data storage unit 311 and the like, and transmits it to the peripheral board 330 to detect the detection target control command. Monitoring of transmission of the detection target command indicated by the information to the peripheral board 330 is started (S1711). The peripheral board 330 temporarily stores the first expected value change data received from the main control board 310 in the peripheral storage unit 332 and the like, and starts monitoring the reception of the detection target command indicated by the detection target control command information (S1761). ). After that, when the main control board 310 generates second expected value change data different from the first expected value change data, the main control board 310 transmits the second expected value change data to the peripheral board 330, and the first expected value change data. Since the change data has already been stored, the second expected value change data is discarded (S1712). When the peripheral board 330 receives the second expected value change data from the main control board 310, the first expected value change data is already stored, and therefore the second expected value change data is discarded (S1762). .

  Further, when the main control board 310 generates the authentication information 1020 (A3) having the third inspection value A3 and transmits it to the peripheral board 330 during monitoring of the detection target control command, the detection indicated by the detection target control command information Switching of the target command is prohibited (S1713). On the other hand, since the peripheral board 330 is monitoring the detection target control command, the main control board 310 is authenticated based on the third inspection value A3 of the authentication information 1020 (A3) received from the main control board 310 (S1763). ), The switching of the detection target command indicated by the detection target control command information is prohibited and the authentication information 1020 (A3) is discarded (S1764). When the main control board 310 transmits a detection target control command to the peripheral board 330 in order to control the peripheral board 330 (S1714), the command is a detection target control command and is stored in the data storage unit 311 or the like. The inspection value is changed using the first expected value changing data (S1715). On the other hand, when the peripheral board 330 receives the detection target control command from the main control board 310, the peripheral board 330 performs a predetermined process corresponding to the command and stores the first expected value change data stored in the peripheral side storage unit 332 or the like. The expected value is changed based on (S1765).

  Subsequently, when generating the expected value change data, the main control board 310 stores the expected value change data in the data storage unit 311 and the like and transmits it to the peripheral board 330 (S1721). The peripheral board 330 temporarily stores the expected value change data received from the main control board 310 in the peripheral storage unit 332 or the like (S1771). Thereafter, when an unauthorized detection target control command is transmitted to the peripheral board 330, the peripheral board 330 performs a predetermined process corresponding to the received illegal detection target control command and stores it in the peripheral storage unit 332 or the like. The expected value is changed based on the expected value changing data (S1772). As a result, the inspection value of the main control board 310 and the expected value of the peripheral board 330 do not match (SS773). Therefore, thereafter, the peripheral portion 330 can no longer authenticate the main control board 310 and can detect fraud.

  According to the pachinko gaming machine 100 described above, the main control board 310 associates two types of data of the authentication information 1020 with each of the first inspection value A1 and the second inspection value A2 among the three types of inspection values. Since the authentication data is generated using the first inspection value A1 or the second inspection value A2, the authentication information 1020 including the authentication data is generated and transmitted to the peripheral substrate 330. Associates the data type with the expected value, so that when the expected value matches the inspection value of the authentication information 1020, the authentication of the main control board 310 can be established and the authentication information to be received next time Since the data type 1020 can be specified, an unauthorized analyst can be prevented from using the authentication information 1020 illegally. In addition, since the inspection value and the expected value change timing based on the expected value change data are associated with a predetermined detection target control command from a plurality of types of control commands, the expected value change data is generated and transmitted. Since the interval between the data and the change using the data can be irregular, it is possible to make illegal analysis difficult. In response to the detection of the same detection target control command as that of the main control board 310, the peripheral board 330 changes the expected value with the expected value change data received from the main control board 310 to obtain the inspection value of the main control board 310. Since they can be matched, the inspection value and the expected value can be changed between the main control board 310 and the peripheral board 330, and the analysis by an unauthorized analyst can be made more difficult. In addition, the main control board 310 and the peripheral board 330 generate a plurality of types of detection target control commands with predetermined detection target control commands in response to detection of generation or transmission and reception of the authentication information 1020 having the third inspection value. Since the switching is performed in a uniform manner, the change timing by the expected value change data can be made more complex, making unauthorized analysis difficult. Since only one type of authentication information 1020 has to be used, the addition to the conventional command system can be minimized and the processing of the main control board 310 can be prevented from becoming complicated. Furthermore, since the peripheral board 330 can detect that the authentication information 1020 has been used illegally by the fraud analyst by the data type of the authentication information 1020, the authentication strength of the authentication information 1020 can be increased. Therefore, even if the data used for authentication and authentication is changed with one type of authentication information 1020, the authentication information 1020 and the unauthorized analysis of the change can be made difficult.

  In the pachinko gaming machine 100 described above, when the main control board 310 generates the authentication information 1020 having the third inspection value again before detecting the detection target control command, the peripheral board 330 also detects the detection target control command. If the authentication information 1020 having the third inspection value is received again before detecting the detection target control command, the detection target control command is changed before the detection target control command is detected. Since switching can be prevented, complication of processing can be prevented. Since the authentication information 1020 having the third inspection value can be used as a dummy between the main control board 310 and the peripheral board 330, unauthorized analysis can be made even more difficult.

  In the pachinko gaming machine 100 described above, for example, the jackpot related command in the pachinko gaming machine 100 such as a jackpot reach command, a jackpot start command, a jackpot command, a jackpot end command, etc. is set as a detection target control command. Since an unauthorized jackpot related command is transmitted to the peripheral board 330 holding the expected value change data because it is easily used illegally, the peripheral board 330 detects it as a detection target control command and changes the expected value. Thus, the inspection value of the main control board 310 and the expected value of the peripheral board 330 can be made inconsistent. Therefore, it is possible to contribute to improving the accuracy of detecting the occurrence of fraud.

  In the pachinko gaming machine 100 described above, if the expected value change data is a test value that is a predetermined initial value and a correction value that changes the expected value, the main control unit 201 and the peripheral unit have a predetermined test value. Since the expected value only needs to be changed with the expected value changing data, the changing process can be simplified.

  In the pachinko gaming machine 100 described above, if the expected value change data is a coefficient value that changes the previously changed inspection value and the expected value, the inspection value and the expected value can be accumulated and changed. Analysis of the expected value can be made more difficult, and unauthorized use of the inspection value and the expected value can be prevented.

  In the pachinko gaming machine 100 described above, expected value changing data for preliminarily storing an expected value of a value different from the test value of the main control unit 201 in the peripheral portion and absorbing the difference between the test value and the expected value Is generated by the main control unit 201 and transmitted to the peripheral unit, the expected value is matched with the inspection value of the main control unit 201 by changing the expected value by the peripheral unit using the expected value changing data. Therefore, it is possible to make it difficult to analyze and use the inspection value and the expected value by an unauthorized analyst.

  Further, in the above-described embodiment, the main control board 310, when detecting the detection target control command, when the number of regenerated authentication information having the third inspection value satisfies a predetermined switching condition, Before detecting the reception of the detection target control command from the main control unit, the peripheral board 330 detects when the number of authentication information having the third inspection value received again satisfies the same switching condition as the main control unit. The target control command may be switched again among a plurality of types of detection target control commands determined in advance.

  For example, the same switching conditions indicating a predetermined number of times, a predetermined order (even number, odd number, etc.) and the like are stored in both the main control board 310 and the peripheral board 330. Then, the main control board 310 counts the number of generations of the authentication information having the third inspection value as a process when it is determined that the monitoring is being performed in step S1215 in the flowchart shown in FIG. 14 (S1215: Yes), It can be realized by determining whether or not the number of generations satisfies the switching condition and adding the process so that the process of step S1216 described above is executed when the switching condition is satisfied. As a result, when the detection target control command is being monitored and the switching condition is satisfied, the main control board 310 uses the detection target control command indicated by the detection target control command information as a reference, and a plurality of types of detection target control indicated by the switching information H. The command can be switched to the detection target control command next to the reference detection target control command and stored in the detection target control command information. Similarly, by adding processing similar to that of the main control board 310 described above as processing when it is determined that monitoring is being performed in step S1408 in the flowchart illustrated in FIG. 16 (S1408: Yes). Can be realized.

  By adopting such a configuration, the detection target control command can be switched before the change by the expected value change data, and therefore the change timing can be further complicated. Also, depending on the switching condition, there are cases where the detection target control command is switched and switching is not performed depending on the detection of the authentication information having the third inspection value, so that unauthorized analysis 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 mentioned above, the same code | symbol is attached | subjected and only a different part is demonstrated in detail.

(Functional configuration of main control board and peripheral board)
First, as shown in FIG. 21, the pachinko gaming machine 100 has a main control board 310 having a function as the main control unit 201 and functions as peripheral units such as the above-described effect control unit 202 and prize ball control unit 203. And a peripheral substrate 330 having the same. The main control board 310 is electrically connected so as to communicate with the peripheral board 330.

  The main control board 310 includes the data storage unit 311, the determination unit 313, the authentication data generation unit 316, the expected value change data generation unit 317, the authentication information generation unit 318, the transmission unit 319, the update unit 320, and the control command detection described above. 321, main control side changing unit 322, detection target switching unit 323, and selection unit 324.

  The selection unit 324 corresponds to the selection unit of the present invention, and when the type information indicates authentication data, the first inspection value and the second inspection value stored in the data storage unit (inspection value storage unit) 311. One test value is randomly selected from the value and the third test value. The selection unit 324 randomly selects one inspection value A using a random number or the like. In the selection method of the selection unit 324, the selection pattern is preferably irregular in order to prevent unauthorized analysis.

  The determination unit 313 described above authenticates the main control board 310 next time with the data types K1 and K2 (see FIG. 13) associated with the first inspection value A1 or the second inspection value A2 selected by the selection unit 324. The data type of the information 1020 is determined. Specifically, when the first inspection value A1 is selected, the next time is determined as the data type K1, and when the second inspection value A2 is selected, the next time is determined as the data type K2. Then, when the selection unit 324 selects the third inspection value A3, the determination unit 313 determines a predetermined data type as the next data type as in the first embodiment. Then, the authentication data generation unit 316 described above generates authentication data having one inspection value selected by the selection unit 324 when the type information indicates authentication data.

  When the pachinko gaming machine 100 according to the second embodiment uses the three types of inspection values for the authentication of the main control board 310 as in the first embodiment, the main control board 310 changes the inspection values with the expected value change data. Therefore, the peripheral board 330 acquires the expected value change data from the main control board 310, and changes the expected value corresponding to the inspection value with the expected value change data, thereby changing the inspection value A configuration is adopted in which the main control board 310 is authenticated based on the expected value. In addition, since the change by the expected value change data can be switched in conjunction with each of a plurality of predetermined detection target control commands, it is difficult to perform an illegal analysis and the control command is used illegally. Can be expected to be difficult. Therefore, even if the pachinko gaming machine 100 authenticates with one type of authentication information, it can make it difficult to illegally analyze the authentication data, so that security can be improved.

  Subsequently, as in the first embodiment, the peripheral board 330 includes the receiving unit 331, the peripheral side storage unit 332, the authentication unit 333, the peripheral side control command detection unit 334, the peripheral side change unit 335, and the peripheral side detection target switching unit 336. , And a specific unit 337. Since the peripheral substrate 330 can be realized with the same configuration as that of the first embodiment, the description thereof is omitted.

  In the second embodiment, the CPU 211 of the main control board 310 functions as the first computer in the claims, and the CPUs 241 and 281 of the peripheral board 330 function as the second computer in the claims. The ROM 212 of the main control board 310 determines the first computer in the claims, authentication data generation means, expected value change data generation means, authentication information generation means, transmission means, update means, control command detection A main control side authentication program for functioning as various means such as means, main control side changing means, detection target switching means, selection means, and the like is stored. In addition, each of the ROMs 242 and 282 of the peripheral board 330 includes the receiving unit, the authenticating unit, the peripheral side control command detecting unit, the peripheral side changing unit, the peripheral side detection target switching unit, the specifying unit, The peripheral side authentication program for functioning as various means such as 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 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 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 power of the pachinko gaming machine 100 is turned on (turned on), the main control unit 201 executes an authenticated process shown in FIG. 22 and determines whether or not it is a predetermined authentication timing in step S1801. If the main control unit 201 determines that it is not the authentication timing (S1801: No), the main control unit 201 proceeds to the process of step S1820. On the other hand, when the main control unit 201 determines that it is the authentication timing (S1801: Yes), the process proceeds to step S1802.

  In step S1802, the main control unit 201 sets the next data type set in the type information of the data storage unit 311 as the current data type, and then proceeds to the processing of step S1803. When the next data type is not set in the type information, that is, in the first process, the initial data type predetermined as an initial value in the pachinko gaming machine 100 is set as the current data type. In the following description, it is assumed that the initial data type is the data type K1 that is authentication data.

  In step S1803, the main control unit 201 determines whether or not the current data type is authentication data. When the data type is not the authentication data, that is, the expected value change data (S1803: No), the main control unit 201 proceeds to the process of step S1804. In step S1804, the main control unit 201 determines whether the detection target control command is being monitored based on whether monitoring start is set in the data storage unit 311 or the like. If the main control unit 201 determines that the monitoring is being performed (S1804: Yes), since the expected value changing data has already been generated, in step S1805, the previous expected value changing data, that is, the data storage. The expected value changing data stored in the unit 311 and the like is stored for generating the authentication information 1020, and then the process proceeds to step S1808. On the other hand, if the main control unit 201 determines that monitoring is not being performed (S1804: No), the process proceeds to step S1806.

  In step S1806, the main control unit 201 randomly generates expected value change data for changing the inspection value and the expected value by a predetermined generation method, and the generated expected value change data is authenticated. The data is stored in the data storage unit 311 or the like for generation of 1020, and then the process proceeds to step S1807. An example of a method for generating expected value change data is to generate the expected value change data by using the generation method using a random number or a pattern table. Then, in step S1807, the main control unit 201 causes the detection target control command monitoring process shown in FIG. 15 described above to function to start monitoring transmission of a predetermined detection target control command, and then in step S1808. Proceed to processing. Note that the detection target control command monitoring process shown in FIG. 15 can be used as it is, and thus detailed description thereof is omitted.

  In step S1808, the main control unit 201 determines a data type predetermined for generating expected value change data as the next data type and stores it in the RAM 213 or the like, and then proceeds to the process of step S1816. The predetermined data type is determined in advance between the main control board 310 and the peripheral board 330.

  On the other hand, when the main control unit 201 determines in step S1803 that the data type is authentication data (S1803: Yes), in step S1809, the three types of first inspection values stored in the data storage unit 311 are displayed. One inspection value is randomly selected from the second inspection value and the third inspection value and stored in the RAM 213 or the like. In step S1810, authentication data having the selected inspection value is generated and stored in the RAM 213 or the like. Thereafter, the process proceeds to step S1811. As a result, authentication data having any one of the three types of inspection values is created.

  In step S1811, the main control unit 201 determines whether the inspection value selected in step S1809 is the third inspection value. If the main control unit 201 determines that the inspection value is not the third inspection value (S1811: No), in step S1812, the main control unit 201 next generates a data type associated with the selected first inspection value or second inspection value. The data type of the authentication information 1020 is determined, and then the process proceeds to step S1816. On the other hand, when the main control unit 201 determines that it is the third inspection value (S1811: Yes), in step S1813, based on whether monitoring start is set in the data storage unit 311 or the like, the detection target control is performed. Determine whether the command is being monitored. If the main control unit 201 determines that monitoring is being performed (S1813: Yes), the process proceeds to step S1815 because expected value change data has already been generated. On the other hand, when the main control unit 201 determines that the monitoring is not being performed (S1813: No), in step S1814, a plurality of types indicated by the switching information H with reference to the detection target control command indicated by the detection target control command information. The detection target control command is switched to the detection target control command next to the reference detection target control command and stored in the detection target control command information, and then the process proceeds to step S1815. In step S1815, the main control unit 201 diverts the next data type set in the type information of the data storage unit 311 and then proceeds to the process of step S1816.

  In step S1816, the main control unit 201 sets a predetermined authentication command in the identification unit 1021 of the authentication information 1020, sets the generated authentication data in the data unit 1022, and generates authentication information 1020. The generated authentication information 1020 is stored in the data storage unit 311 or the like, and then the process proceeds to step S1817.

  In step S1817, the main control unit 201 encrypts the generated authentication information 1020 with a predetermined encryption method with the peripheral unit, and in step S1818, based on each of the encrypted authentication information 1020. Then, an authentication information signal is generated and transmitted from the transmission unit 317 to the peripheral unit, and then the process proceeds to step S1819. If encryption is not required between the main control unit 201 and the peripheral unit, the processing in step S1817 is deleted and the authentication information 1020 is transmitted to the peripheral unit as it is. In step S1819, the main control unit 201 updates the type information in the data storage unit 311 to indicate the next data type determined in step S1808 or step S1812, and then proceeds to the process of step S1820.

  In step S1820, 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 (S1820: No), the main control unit 201 returns to the process of step S1801 and repeats a series of processes. On the other hand, when the main control unit 201 determines that the power is turned off (S1820: Yes), the process according to this flowchart ends.

  Subsequently, the authentication information signal reception processing procedure performed by the peripheral CPUs 241 and 281 (second computer) uses the authentication-side processing shown in FIG. 16 and the peripheral-side command monitoring processing shown in FIG. Therefore, detailed description is omitted.

(Example 2 of authentication processing procedure using authentication information)
Next, when the data types K1 and K2 shown in FIG. 12 are switched, the first to third inspection values and the first to third expected values are changed, and the change timing is changed to authenticate the main control board 310. An example of the procedure in the pachinko gaming machine 100 will be described with reference to the drawings of FIGS. In the present embodiment, it is assumed that the switching information H indicates that two types of detection target control commands, a jackpot start command and a jackpot end command, are switched in that order.

  In FIG. 23, the main control board 310 which is the person to be authenticated sets a predetermined data type K1 for this time (S1901). The main control board 310 randomly selects one second inspection value A2 from the three types of inspection values in the data storage unit 311 (S1902), and generates authentication data for the second inspection value A2 (S1903). . The main control board 310 generates authentication information 1020 (A2) having the authentication data, and transmits the authentication information 1020 (A2) to the peripheral board 330 (S1904). Then, as shown in FIG. 13, the main control board 310 determines the data type K2 associated with the selected second inspection value A2, the authentication information 1020 to be generated next time as the data type K2, and the type information. Update (S1905).

  On the other hand, when the peripheral board 330 sets the predetermined data type K1 for this time (S1951) and receives the authentication information 1020 (A2) from the main control board 310 (S1952), this time indicates authentication data. Therefore, it is determined whether or not the authentication data in the data portion 1022 of the authentication information 1020 (A2) matches the three types of expected values stored in the peripheral storage portion 332, thereby authenticating the main control board 310. Is performed (S1953). When the authentication is established, the peripheral substrate 330 corresponds to the second expected value B2 because the authentication data is the second inspection value A2, and therefore coincides with the second expected value B2 of the peripheral storage unit 332. The attached data type K2 is specified as the next data type, and the peripheral side type information in the peripheral side storage unit 332 is updated to indicate the data type K2 (S1954).

  Subsequently, the main control board 310 sets the data type K2 indicated by the type information in the data storage unit 311 as the current data type (S1906). Since the type information indicates the data type K2, the main control board 310 randomly generates the expected value change data C1 for changing the inspection value and the expected value by a predetermined generation method (S1907). ), Authentication information 1020 (C1) having the expected value change data C1 is generated, and the authentication information 1020 (C1) is transmitted to the peripheral board 330 (S1908). Then, the main control board 310 updates the authentication information 1020 to be generated next time as the data type K1 for the predetermined data type K1, and updates the type information (S1909). When the main control board 310 detects the transmission of the jackpot start command, which is the detection target control command indicated by the detection target control command information in the data storage unit 311, to the peripheral board 330 (S 1910), the main control board 310 includes the expected value change data C 1. Based on the above-described changing method, three types of inspection values are changed (S1911). Accordingly, in this embodiment, it is assumed that the change method in the pachinko gaming machine 100 is “+”, and the main control board 310 is set to the first inspection value A1 + C1, the second inspection value A2 + C1, and the third inspection value A3 + C1. Each has been changed.

  On the other hand, the peripheral board 330 sets the current data type K2 based on the peripheral side type information of the peripheral side storage unit 332 (S1955) and receives the authentication information 1020 (C1) from the main control board 310. Since the value change data is shown, the expected value change data C1 of the data portion 1022 of the authentication information 1020 (C1) is stored in the peripheral storage unit 332 or the like (S1956). Then, the peripheral board 330 specifies a data type K1 predetermined for generating expected value change data as the next data type, and the peripheral side type of the peripheral side storage unit 332 indicates the data type K1. Information is updated (S1957). When the peripheral board 330 detects reception of the jackpot start command, which is the detection target control command indicated by the detection target control command information in the peripheral storage unit 332, from the main control board 310 (S1958), the expected value change data C1 Based on the above, the three types of expected values in the peripheral storage unit 332 are changed by the above-described changing method (S1959). The peripheral board 330 has been changed to the first expected value B1 + C1, the second expected value B2 + C1, and the third expected value B3 + C1 that match the inspection values of the main control board 310, respectively.

  Subsequently, the main control board 310 sets the data type K1 indicated by the type information in the data storage unit 311 as the current data type (S1912). The main control board 310 randomly selects one third inspection value A3 + C1 from the three types of inspection values in the data storage unit 311 (S1913), and generates authentication data for the third inspection value A3 + C1 (S1914). . The main control board 310 generates authentication information 1020 (A3 + C1) having the authentication data, and transmits the authentication information 1020 (A3 + C1) to the peripheral board 330 (S1915). Then, the main control board 310 diverts the data type K1 indicated by the type information in the data storage unit 311 as the next data type (S1916). Then, the main control board 310 switches the detection target control command from the jackpot start command to the jackpot end command based on the switching information H described above and sets the detection target control command information in the detection target control command information (S1917).

  On the other hand, the peripheral board 330 sets the current data type K1 based on the peripheral side type information in the peripheral side storage unit 332 (S1960), and receives the authentication information 1020 (A3 + C1) from the main control board 310 (S1961). Since authentication data is shown this time, it is determined whether or not the authentication data in the data portion 1022 of the authentication information 1020 (A3 + C1) matches the three types of expected values stored in the peripheral side storage portion 332. The main control board 310 is authenticated by making a determination (S1962). When the authentication is established, the peripheral substrate 330 uses the data type K1 indicated by the peripheral side type information in the peripheral side storage unit 332 as the next data type because the authentication data is the third inspection value A3 + C1 ( S1963). Then, similarly to the main control board 310, the peripheral board 330 switches the detection target control command from the jackpot start command to the jackpot end command based on the switching information H described above and sets the detection target control command information in the detection target control command information (S1964). .

  Subsequently, in FIG. 24, the main control board 310 sets the data type K1 indicated by the type information in the data storage unit 311 as the current data type (S1918). The main control board 310 randomly selects one first inspection value A1 + C1 from the three types of inspection values in the data storage unit 311 (S1919), and generates authentication data for the first inspection value A1 + C1 (S1920). . The main control board 310 generates authentication information 1020 (A1 + C1) having the authentication data, and transmits the authentication information 1020 (A1 + C1) to the peripheral board 330 (S1921). Then, the main control board 310 determines the data type K1 associated with the selected first inspection value A1 + C1 as the data type K1 for the authentication information 1020 to be generated next time and updates the type information (S1922).

  On the other hand, the peripheral board 330 sets the current data type K1 based on the peripheral side type information in the peripheral side storage unit 332 (S1965), and receives the authentication information 1020 (A1 + C1) from the main control board 310 (S1966). Since authentication data is shown this time, it is determined whether or not the authentication data in the data portion 1022 of the authentication information 1020 (A1 + C1) matches the three types of expected values stored in the peripheral storage unit 332. The main control board 310 is authenticated by making a determination (S1967). When the authentication is established, the peripheral substrate 330 corresponds to the first expected value B1 + C1 because the authentication data is the first inspection value A1 + C1 and matches the first expected value B1 + C1 of the peripheral storage unit 332. The attached data type K1 is specified as the next data type, and the peripheral type information in the peripheral storage unit 332 is updated to indicate the data type K1 (S1968).

  Subsequently, the main control board 310 sets the data type K1 indicated by the type information in the data storage unit 311 as the current data type (S1923). The main control board 310 randomly selects one second inspection value A2 + C1 from the three types of inspection values in the data storage unit 311 (S1924), and generates authentication data for the inspection value A2 + C1 (S1925). The main control board 310 generates authentication information 1020 (A2 + C1) having the authentication data, and transmits the authentication information 1020 (A2 + C1) to the peripheral board 330 (S1926). Then, the main control board 310 updates the data type K2 associated with the selected second inspection value A2 + C1 to the authentication information 1020 to be generated next time as the data type K2 and updates the type information (S1927).

  On the other hand, the peripheral board 330 sets the current data type K1 based on the peripheral side type information in the peripheral side storage unit 332 (S1969), and receives the authentication information 1020 (A2 + C1) from the main control board 310 (S1970). Since authentication data is shown this time, it is determined whether or not the authentication data in the data portion 1022 of the authentication information 1020 (A2 + C1) matches the three types of expected values stored in the peripheral storage unit 332. The main control board 310 is authenticated by making a determination (S1971). Then, since the authentication data is the second inspection value A2 + C1 when the authentication is established, the peripheral board 330 matches the second expected value B2 + C1 of the peripheral storage unit 332, and therefore corresponds to the second expected value B2 + C1. The attached data type K2 is specified as the next data type, and the peripheral side type information in the peripheral side storage unit 332 is updated to indicate the data type K2 (S1972).

  Subsequently, the main control board 310 sets the data type K2 indicated by the type information in the data storage unit 311 as the current data type (S1928). Since the type information indicates the data type K2, the main control board 310 randomly generates the expected value change data C2 for changing the inspection value and the expected value by a predetermined generation method (S1929). ), Authentication information 1020 (C2) having the expected value change data C2 is generated, and the authentication information 1020 (C2) is transmitted to the peripheral board 330 (S1930). Then, the main control board 310 updates the type information of the predetermined data type K1 by determining the authentication information 1020 to be generated next time as the data type K1 (S1931). When the main control board 310 detects the transmission of the jackpot end command, which is the detection target control command indicated by the detection target control command information in the data storage unit 311, to the peripheral board 330 (S 1932), the data is sent to the expected value change data C 2. Based on the above-described change method, the three types of inspection values are changed (S1933). As a result, the main control board 310 is changed to the first inspection value A1 + C2, the second inspection value A2 + C2, and the third inspection value A3 + C2.

  On the other hand, the peripheral board 330 sets the current data type K2 based on the peripheral side type information in the peripheral side storage unit 332 (S1973), and when the authentication information 1020 (C2) is received from the main control board 310, this time is expected. Since the value change data is shown, the expected value change data C2 of the data portion 1022 of the authentication information 1020 (C2) is stored in the peripheral storage unit 332 or the like (S1974). The peripheral board 330 specifies the data type K1 predetermined for generating the expected value change data as the next data type, and uses the peripheral side type information of the peripheral storage unit 332 to indicate the data type K1. Update (S1975). When the peripheral board 330 detects reception of the jackpot end command, which is the detection target control command indicated by the detection target control command information in the peripheral storage unit 332, from the main control board 310 (S1976), the expected value change data C1 Based on the above, the three types of expected values in the peripheral storage unit 332 are changed by the above-described changing method (S1977). As a result, the peripheral board 330 is changed to the first expected value B1 + C2, the second expected value B2 + C2, and the third expected value B3 + C2 that match the inspection values of the main control board 310, respectively. Thereafter, the same authentication process as described above is performed.

(Example of change procedure using expected value change data)
Next, the change procedure when each of the main control board 310 and the peripheral board 330 according to the second embodiment changes the inspection value and the expected value using the expected value change data is also the change procedure shown in FIG. Therefore, the description thereof is omitted.

  According to the pachinko gaming machine 100 described above, as in the first embodiment, the main control board 310 includes authentication information 1020 2 in each of the first inspection value A1 and the second inspection value A2 among the three types of inspection values. Data types are associated with each other, authentication data is generated using the first inspection value A1 or the second inspection value A2, and authentication information 1020 including the authentication data is generated and transmitted to the peripheral board 330. Therefore, the peripheral board 330 can establish authentication of the main control board 310 when the expected value matches the inspection value of the authentication information 1020 by associating the data type with the expected value. In addition, since the data type of the authentication information 1020 to be received next time can be specified, it is possible to prevent an unauthorized analyst from using the authentication information 1020 illegally. In addition, since the inspection value and the expected value change timing based on the expected value change data are associated with a predetermined detection target control command from a plurality of types of control commands, the expected value change data is generated and transmitted. Since the interval between the data and the change using the data can be irregular, it is possible to make illegal analysis difficult. In response to the detection of the same detection target control command as that of the main control board 310, the peripheral board 330 changes the expected value with the expected value change data received from the main control board 310 to obtain the inspection value of the main control board 310. Since they can be matched, the inspection value and the expected value can be changed between the main control board 310 and the peripheral board 330, and the analysis by an unauthorized analyst can be made more difficult. In addition, the main control board 310 and the peripheral board 330 generate a plurality of types of detection target control commands with predetermined detection target control commands in response to detection of generation or transmission and reception of the authentication information 1020 having the third inspection value. Since the switching is performed in a uniform manner, the change timing by the expected value change data can be made more complex, making unauthorized analysis difficult. Since only one type of authentication information 1020 has to be used, the addition to the conventional command system can be minimized and the processing of the main control board 310 can be prevented from becoming complicated. Furthermore, since the peripheral board 330 can detect that the authentication information 1020 has been used illegally by the fraud analyst by the data type of the authentication information 1020, the authentication strength of the authentication information 1020 can be increased. Therefore, even if the data used for authentication and authentication is changed with one type of authentication information 1020, the authentication information 1020 and the unauthorized analysis of the change can be made difficult.

  In the pachinko gaming machine 100 described above, when the main control board 310 generates the authentication information 1020 having the third inspection value again before detecting the detection target control command, the peripheral board 330 also detects the detection target control command. If the authentication information 1020 having the third inspection value is received again before detecting the detection target control command, the detection target control command is changed before the detection target control command is detected. Since switching can be prevented, complication of processing can be prevented. Since the authentication information 1020 having the third inspection value can be used as a dummy between the main control board 310 and the peripheral board 330, unauthorized analysis can be made even more difficult.

  In the pachinko gaming machine 100 described above, for example, the jackpot related command in the pachinko gaming machine 100 such as a jackpot reach command, a jackpot start command, a jackpot command, a jackpot end command, etc. is set as a detection target control command. Since an unauthorized jackpot related command is transmitted to the peripheral board 330 holding the expected value change data because it is easily used illegally, the peripheral board 330 detects it as a detection target control command and changes the expected value. Thus, the inspection value of the main control board 310 and the expected value of the peripheral board 330 can be made inconsistent. Therefore, it is possible to contribute to improving the accuracy of detecting the occurrence of fraud.

  In the pachinko gaming machine 100 described above, if the expected value change data is a test value that is a predetermined initial value and a correction value that changes the expected value, the main control unit 201 and the peripheral unit have a predetermined test value. Since the expected value only needs to be changed with the expected value changing data, the changing process can be simplified.

  In the pachinko gaming machine 100 described above, if the expected value change data is a coefficient value that changes the previously changed inspection value and the expected value, the inspection value and the expected value can be accumulated and changed. Analysis of the expected value can be made more difficult, and unauthorized use of the inspection value and the expected value can be prevented.

  In the pachinko gaming machine 100 described above, expected value changing data for preliminarily storing an expected value of a value different from the test value of the main control unit 201 in the peripheral portion and absorbing the difference between the test value and the expected value Is generated by the main control unit 201 and transmitted to the peripheral unit, the expected value is matched with the inspection value of the main control unit 201 by changing the expected value by the peripheral unit using the expected value changing data. Therefore, it is possible to make it difficult to analyze and use the inspection value and the expected value by an unauthorized analyst.

  Further, in the pachinko gaming machine 100 according to the second embodiment described above, the main control board 310 sets a switching condition in which the number of regenerated authentication information having the third inspection value is determined in advance before the detection target control command is detected. When the condition is satisfied, the number of the authentication information having the third inspection value received again before the peripheral board 330 detects reception of the detection target control command from the main control unit is the same switching condition as the main control unit. When the above condition is satisfied, the detection target control command may be switched again among a plurality of types of detection target control commands determined in advance.

  For example, the same switching conditions indicating a predetermined number of times, a predetermined order (even number, odd number, etc.) and the like are stored in both the main control board 310 and the peripheral board 330. Then, the main control board 310 counts the number of times the authentication information having the third inspection value is generated as a process when it is determined that the monitoring is being performed in step S1813 in the flowchart shown in FIG. 22 (S1813: Yes), It can be realized by determining whether or not the number of generations satisfies the switching condition and adding the process so as to execute the process of step S1814 described above when the switching condition is satisfied. As a result, when the detection target control command is being monitored and the switching condition is satisfied, the main control board 310 uses the detection target control command indicated by the detection target control command information as a reference, and a plurality of types of detection target control indicated by the switching information H. The command can be switched to the detection target control command next to the reference detection target control command and stored in the detection target control command information. Similarly, by adding processing similar to that of the main control board 310 described above as processing when it is determined that monitoring is being performed in step S1408 in the flowchart illustrated in FIG. 16 (S1408: Yes). Can be realized.

  By adopting such a configuration, the detection target control command can be switched before the change by the expected value change data, and therefore the change timing can be further complicated. Also, depending on the switching condition, there are cases where the detection target control command is switched and switching is not performed depending on the detection of the authentication information having the third inspection value, so that unauthorized analysis can be made even more difficult.

  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.
