Description

  The present invention relates to a gaming machine, a main control board, a peripheral board, an gaming machine authentication method, and an authentication program that include a plurality of boards and perform authentication of communication between these boards.

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

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

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

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

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

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

  As described above, according to the present invention, a plurality of types of setting patterns and a plurality of types of authentication values are associated with each other in a one-to-one correspondence with the next setting pattern so that the main control side becomes the current setting pattern. The authentication value and the history data indicating the history of the control command are set to generate a plurality of types of authentication information, and the plurality of types of authentication information are transmitted to the subsequent stage via the peripheral side. By performing authentication on the main control side based on the authentication value set for each of the multiple types of authentication information, the history data setting pattern, and the validity of the control command indicated by the history data, an unauthorized analyst It is difficult to analyze multiple types of authentication information, and it is possible to prevent unauthorized analysts from using the authentication information illegally, and that the control command is illegally used by the unauthorized analyst on the rear stage and the peripheral side. It can be known. Furthermore, since the number of setting patterns can be increased by increasing the number of plural types of authentication information, the authentication strength can be increased. In addition, it is more difficult for an unauthorized analyst to analyze setting pattern switching in a gaming machine by specifying a setting pattern corresponding to the authentication value from the expected value in the subsequent stage and setting it as the next setting pattern. It can be. In addition, since the latter part performs authentication processing for the main control side and transmits the subsequent authentication result to the peripheral side, the peripheral side only needs to refer to the subsequent authentication result without performing the authentication process. The processing load on the peripheral CPU can be reduced. Furthermore, since a plurality of types of authentication values can be stored in advance, it is not necessary to perform complicated calculations when generating authentication information, and an increase in processing load on the main control side can be prevented. In addition, since the peripheral side transfers control commands received from the main control side to the subsequent stage, and the subsequent stage manages the history of control commands from the main control section, control history management is unnecessary on the peripheral side. Therefore, it is possible to prevent an increase in processing load on the peripheral side due to security improvement. Moreover, since the peripheral side can transfer the control command received from the main control side to the subsequent stage and perform predetermined processing, the peripheral side and the subsequent stage can perform processing simultaneously. It is possible to prevent a delay in the processing. Therefore, it is possible to prevent the data transmitted from the main control side to the peripheral side from being used for unauthorized control and reduce the processing load on the peripheral CPU without using complicated calculations. Further, even if the authentication process is complicated, it does not affect the effect process on the peripheral side, so that it is possible to improve both the security and the fun of the game.

  In the gaming machine described above, since multiple authentication values can be set for multiple types of authentication information, the number of setting patterns used between the main control side and the subsequent stage can be increased. It is even more difficult for an analyst to analyze multiple types of authentication information, and it is possible to prevent an unauthorized analyst from using the authentication information illegally, and that the data is illegally used by the unauthorized analyst. Can be detected in the part. In addition, since the peripheral side only needs to refer to the subsequent authentication result without performing the authentication process, the processing load on the peripheral CPU can be reduced.

  In the above-mentioned gaming machine, the history data and the latter-stage history data indicate the history of the control command for a plurality of times. Therefore, it is possible to improve the authentication accuracy. Then, by setting the history data and the latter-stage history data to values obtained by calculating past history data, analysis by an unauthorized analyst can be made even more difficult.

  In the above-described gaming machine, history data can be set for all types of authentication information, and in this case, the initial setting pattern is set as the next setting pattern, so analysis of setting pattern switching is performed. Therefore, it is possible to prevent unauthorized use and improve detection accuracy.

  In the above-described gaming machine, the main control side transmits the plurality of types of authentication information to the subsequent stage in the order of the plurality of types of authentication information defined by the setting pattern. Since the authentication on the main control side can be performed based on the authentication value of the authentication data set for each type of authentication information, the setting pattern of the history data and their order, the authentication accuracy can be improved without using complicated calculations. Improvements can be made.

  In the above-described gaming machine, since multiple types of authentication information generated by the main control side are transmitted to the subsequent stage in an irregular order via the peripheral side, an unauthorized analyst analyzes the multiple types of authentication information. It is even more difficult to prevent the unauthorized analyst from using the authentication information illegally, and the latter part can detect that the data is illegally used by the unauthorized analyst.

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 determination unit 312, an authentication value extraction unit 314, an authentication information generation unit 315, and a main control side transmission unit. 316 is configured. The main control board 310 is formed of a board different from the peripheral board 330, and is electrically connected so as to be communicable with the peripheral portion 202A of the peripheral board 330.

  The data storage unit 311 corresponds to history data storage means, pattern information storage means, and authentication value storage means of the present invention, and stores various data such as control command data, history data, pattern information, and multiple types of authentication values. ing. As the data storage unit 311, for example, a part of the ROM 212 and the RAM 213 (see FIG. 2) of the main control unit 201 can be used. The data storage unit 311 has a storage area for storing a plurality of types of authentication information transmitted from the main control board 310 to the rear stage unit 202B via the peripheral unit 202A in time series. The number of types of authentication information stored in the data storage unit 311 is defined by the number of information used for one authentication of the main control board 310. Since each of a plurality of types of authentication information has control command data, in the present embodiment, the case where the control command data is used as a history will be described. Instead, a plurality of types of authentication information is used. Apart from that, the control command data may be stored in the data storage unit 311.

  The history data stored in the data storage unit 311 is data indicating the history of the control command transmitted from the main control unit 201 (main control board 310) to the rear stage unit 202B via the peripheral unit 202A. The history data is updated by history data generating means for generating history data at a predetermined update timing such as generation of a control command, transmission of the control command to the peripheral portion 202A, and the like. Then, the history data generation means generates the history data by calculating the control command data for a predetermined number of transmissions by, for example, an error detection method, a predetermined encryption method, an exclusive OR, etc., and the generated history data The history data stored in the data storage unit 311 is updated to the data. When history data is used as a checksum, the history data is a total value obtained by summing up a plurality of control command data. Note that the history data can use the control command for one time such as the previous time or a predetermined number of times as it is, thereby simplifying the process when generating authentication information, which will be described later.

  The pattern information is information indicating a plurality of types of setting patterns for setting an authentication value used for the authentication or the history data in each of a plurality of types of authentication information used for authentication of the main control unit 201. For example, the pattern information is a data structure, table, or the like having flag data indicating whether authentication data set in each of a plurality of types of authentication information is valid or invalid as an authentication value of the main control unit 201. Realize. That is, when valid authentication data is valid data and invalid authentication data is invalid data, an authentication value is set for valid data, and the history data is set for invalid data. When a plurality of invalid data are set in a plurality of types of authentication information, history data may be set for all invalid data, or history data may be set only for at least one invalid data. Anyway.

  The plurality of types of authentication values are associated one-to-one with each of the plurality of types of setting patterns indicated by the pattern information. Each of the plurality of types of authentication values is different data, and examples thereof include checksums of a plurality of types of predetermined areas in the ROM 212 of the main control unit 201, predetermined unique values, and the like.

  The determining unit 312 corresponds to a determining unit of the present invention, determines a next setting pattern to be used for the next authentication of the main control unit 201 from a plurality of types of setting patterns indicated by the pattern information, and determines the determined setting pattern. The next set pattern data shown is stored in the data storage unit 311 or the like. The determination unit 312 makes it difficult for an unauthorized analyst to analyze illegally by determining the next set pattern irregularly using a random number or the like.

  The authentication value extraction unit 314 corresponds to the authentication value extraction unit of the present invention, extracts the authentication value associated with the next setting pattern determined by the determination unit 312 from the data storage unit (authentication value storage unit) 311, The extracted authentication value is stored in the RAM 213 or the like. Then, the authentication value extracted by the authentication value extraction unit 314 becomes an authentication value used for the current authentication.

  The authentication information generation unit 315 corresponds to the authentication information generation unit of the present invention, and the authentication value extracted by the authentication value extraction unit 314 and the history data stored in the data storage unit 311 are determined in advance. A plurality of types of authentication information are generated so as to be set by a setting pattern. The current setting pattern determined in advance is an initial setting pattern that is a predetermined initial value in the first process of the authentication information generation unit 315, and the previous process is performed in the second and subsequent processes. The determined setting pattern is the next time.

  When generating authentication information indicating that the setting pattern is valid, the authentication information generation unit 315 sets the authentication value extracted by the authentication value extraction unit 314 as authentication data and generates authentication information. Further, when generating authentication information indicating that the setting pattern is invalid, the authentication information generation unit 315 sets the history data stored in the data storage unit 311 as authentication data and generates authentication information. That is, each of the plurality of types of authentication information is information having authentication data, and the authentication data is valid data that is an authentication value or invalid data that is different from the authentication value of the main control unit 201.

The subsequent authentication result data generation unit 335 has a valid control command history, and valid data (authentication value) and invalid data (history data) are included in each of a plurality of types of authentication information according to the current setting pattern. If set, it is determined that the main control board 310 is a legitimate main control board 310 and authentication is established. Further, the post-authentication result data generation unit 335 determines that the control command history is not valid, or is not set according to the current setting pattern, and is an unauthorized main control board 310, and authentication is not established. To do. The post-authentication result data generation unit 335 generates post-authentication result data indicating whether authentication of the main control board 310 (main control unit) has been established. That is, the latter-stage authentication result data indicates an authentication result indicating whether or not the latter-stage unit 202B has authenticated the main control board 310 (main control unit 201).

  The post-stage transmission unit 336 corresponds to the post-stage transmission unit of the present invention, and transmits the post-stage authentication result data generated by the post-stage authentication result data generation unit 335 to the peripheral unit 202A.

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, the control process of the effect control unit 202A 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 202A. That is, in the description of FIGS. 4 to 9, “send a command” means “send a control signal including data (control command data) indicating the command”. The presence or absence of data is not considered.

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

  In step S402, the main control unit 201 transmits a power-on command to each peripheral unit such as the effect control unit 202A 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 202A 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 410. 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 202A, and the process of step S407 Migrate to

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

  In step S412, the main control unit 201 determines whether or not the jackpot determination random number is a jackpot random number. If the main control unit 201 determines that it is a jackpot random number (S412: Yes), in step S413, the main control unit 201 transmits a jackpot reach command (symbol variation command) to the effect control unit 202A. 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 202A, 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 202A. Subsequently, in step S417, the main control unit 201 sequentially transmits commands corresponding to each of the big hits (jackpot command) to the effect control unit 202A. To do. Then, 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 202A 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 (symbol variation command) to the effect control unit 202A. 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 202A, and proceeds to the process of step S422.

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

  The various commands in FIGS. 4 and 5 described above correspond to the control commands of the present invention, and the main control board 310 stores the control command data in the data storage unit 311 as a history each time the various control commands are transmitted. ing. In response to the storage of the control command data, the main control board 310 updates the history data in the data storage unit 311. Note that the history data is updated when a plurality of types of authentication information is generated, so that the processing load on the main control board 310 can be reduced. In addition, every time the control unit 202 receives the various control commands, the post-stage unit 202 </ b> B of the peripheral substrate 330 stores the control command data in the post-stage storage unit 332 as a history, and updates the post-stage history data of the post-stage storage unit 332. To do.

  Next, referring to the drawing of FIG. 6 for 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 202A in the pachinko gaming machine 100 To explain.

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

  In the following, description will be given of a process when the symbol changes (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.

  First, the symbol variation process by the effect control unit 202A will be described with reference to the flowchart shown in FIG. The effect control unit 202A 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 202A repeats this determination process to wait for the symbol variation command to be received. On the other hand, when it is determined that the symbol variation command has been received (S701: Yes), the effect control unit 202A 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. Then, in step S704, the effect control unit 202A 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 202A determines whether the effect time has elapsed. When it is determined that the production time has elapsed (S705: Yes), the production control unit 202A 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 202A determines whether or not a symbol stop command has been received from the main control unit 201 in step S706. And when it determines with the effect control part 202A 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, if the effect control unit 202A determines that the symbol stop command has been received (S706: Yes), in step S707, the effect stop command is transmitted to the lamp control unit 251 and the voice control unit 252, and according to this flowchart. The process ends.

  Next, the big hitting process by the effect control unit 202A will be described with reference to the flowchart shown in FIG. The effect control unit 202A determines whether or not a jackpot start command (see step S416 in FIG. 5) has been 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 202A waits for reception of the jackpot start command by repeating this determination process. On the other hand, if it is determined that the jackpot start command has been received (S801: Yes), the effect control unit 202A 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 202A determines whether 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 202A waits for reception of the jackpot command by repeating this determination process. On the other hand, when it is determined that the jackpot command has been received (S803: Yes), the effect control unit 202A has a round corresponding to the round jackpot command received by the lamp control unit 251 or the voice control unit 252 in step S804. Another processing command is transmitted, and the process proceeds to step S805.

  In step S805, the effect control unit 202A determines whether 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 202A waits for reception of the jackpot end command by repeating this determination process. On the other hand, when it is determined that the jackpot end command has been received (S805: Yes), the effect control unit 202A 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 a production start command is received from the production control unit 202A (during symbol variation) will be described. Then, in step S901 illustrated in FIG. 9, the lamp control unit 251 determines whether or not an effect start command has been received from the effect control unit 202A. When it is determined that the effect start command has not been received (S901: No), the lamp control unit 251 waits for the reception of the effect start command by repeating this determination process. On the other hand, if the lamp control unit 251 determines that an effect start command has been received (S901: Yes), in step S902, the command-specific data prepared in advance for each command is read, and the process proceeds to step S903.

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

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

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

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

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

(Authentication information data format)
Next, an example in which an authentication information signal different from the control signal 1010 described above has authentication information will be described. In this embodiment, it is assumed that the main control unit 201 transmits an authentication information signal from the main control unit 201 to the rear stage unit 202B by outputting an authentication information signal to the rear stage unit 202B via the peripheral unit 202A. To do.

  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 are a plurality of different types of authentication commands. For example, hexadecimal values such as 0xA0 and 0xB0 are set. As a result, the post-stage unit 202B can identify each of a plurality of types of authentication information 1020 based on the identification unit 1021. The authentication command can be differentiated from the control command data 1001 by using a command different from the control command of the control command data 1001 described above.

  In the data unit 1022, based on the setting pattern described above, either the valid authentication value used for authentication of the main control unit 201 or the history data invalid as the authentication value is set as the authentication data. In the authentication data, the authentication value is valid data, and the history data is invalid data. In addition, when valid data is set in a plurality of authentication commands, for example, an authentication value is set only for a predetermined authentication command in which all authentication values are set, and other authentication commands are set in other cases. The authentication value can be set to various embodiments. In the case where there are a plurality of invalid data, history data is set for all in this embodiment, but instead, history data is set only for predetermined authentication information, and otherwise authentication values and history are set. An embodiment in which data different from the data is set may be employed. Further, the data unit 1022 may have other configurations such as attaching other data to the authentication value or history data.

  Subsequently, the post-stage authentication result signal shown in FIG. 11 includes the post-stage authentication result information 1030 indicating the authentication result obtained by authenticating the main control unit 201 using the plural types of authentication information 1020 described above by the post-stage unit 202B. Send to. The latter authentication result information 1030 includes an identification unit 1031 and a result unit 1032. In the identification unit 1031, identification data that can identify the subsequent authentication result information 1030 is set. As the identification data, various embodiments such as diverting data set in the identification unit 1021 of the authentication information 1020 or using predetermined data can be used.

  Next, an example in which a plurality of types of authentication information 1020 used in one authentication process of the main control unit 210 is set as one set will be described below.

  First, when two authentication information 1020 are set as one set, different authentication commands C1 and C2 are set in the identification unit 1021 of each authentication information 1020 as shown in FIG. When the setting pattern indicates that the authentication command C1 is invalid (history) and the authentication command C2 is valid (authentication), the data portion 1022 corresponding to the authentication command C1 includes the history data invalid as an authentication value. Some invalid data is set, and valid data as the authentication value is set in the data portion 1022 corresponding to the authentication command C2. Thereby, generation of one set of authentication information 1020 is completed.

  Subsequently, when generating three pieces of authentication information 1020 as one set using two kinds of authentication commands C1 and C2, as shown in FIG. 13, the identification command 102 in the identification unit 1021 of the two pieces of authentication information 1020 includes the authentication command C1. The authentication command C2 is set in the identification unit 1021 of the remaining one authentication information 1020. If the setting pattern indicates that the authentication command C1 is invalid (history) and the authentication command C2 is valid (authentication), invalid data that is history data is stored in each of the two data portions 1022 corresponding to the authentication command C1. Is set, and valid data as the authentication value is set in one data portion 1022 corresponding to the authentication command C2. Thereby, the generation of the authentication information 1020 for one set is completed.

  Subsequently, when three different pieces of authentication information 1020 are set as one set, as shown in FIG. 14, different authentication commands C1, C2, and C3 are set in the identification unit 1021 of each piece of authentication information 1020. When the setting pattern indicates that the authentication commands C1 and C2 are valid (authentication) and the authentication command C3 is invalid (history), each of the data portions 1022 corresponding to the authentication commands C1 and C2 includes the authentication value. Some valid data is set, and invalid data which is the history data is set in the data portion 1022 corresponding to the authentication command C3. Thereby, the generation of three different types of authentication information 1020 in one set is completed.

  As described above, since multiple types of authentication information 1020 are set with the above-described setting patterns corresponding to a plurality of types of authentication commands C1 to C3, effective authentication values and history data are set by switching the plurality of types of setting information. Since the authentication value set in the type of authentication information 1020 and the setting pattern of the history data can be switched, it is difficult for an unauthorized analyst to analyze it.

(Setting pattern switching example)
Next, a configuration example for switching a plurality of types of setting patterns by the main control unit 201 and specifying the setting pattern to be switched by the subsequent stage unit 202B using an authentication value will be described.

  In FIG. 15, when using four setting patterns P1 to P4, the main control unit 201 uses four authentication values A1 to A4 corresponding to each of the setting patterns P1 to P4. The pattern information D is information indicating a plurality of types of setting patterns P1 to P4. In the present embodiment, the pattern information D is information indicating the setting pattern P in association with each setting of the setting commands C1 and C2. Specifically, in the setting pattern P1, the authentication command C1 is invalid (history), and the authentication command C2 is invalid (history). In the setting pattern P2, the authentication command C1 is invalid (history), and the authentication command C2 is valid (authentication). In the setting pattern P3, the authentication command C1 is valid (authentication), and the authentication command C2 is invalid (history). In the setting pattern P4, the authentication command C1 is valid (authentication), and the authentication command C2 is valid (authentication). Since the setting patterns P1 to P4 and the authentication values A1 to A4 included in the pattern information D are associated one-to-one, the link destination can be traced from each of the authentication value A and the setting pattern P. The setting pattern P defines the order of the authentication command C1 and the authentication command C2 as the authentication (transmission) order, so that elements of the order can be added to the setting pattern and the number of setting patterns can be increased. .

  As shown in FIG. 16, the subsequent stage unit 202 </ b> B corresponding to this stores the expected values B <b> 1 to B <b> 4 that match the authentication values A <b> 1 to A <b> 4 in the subsequent stage storage unit 332. Then, the rear stage unit 202B stores the setting patterns P1 to P4 corresponding to the authentication values A1 to A4 in association with the expected values B1 to B4, respectively. Thereby, the latter stage part 202B can specify one setting pattern P from the expected value B. The association between the expected values B1 to B4 and the setting patterns P1 to P4 of the present embodiment will be described on the assumption that the expected values B1 to B4 are associated with the pattern information D described above. An embodiment in which the data indicating the expected values B1 to B4 and the setting patterns P1 to P4 are associated with each other may be employed.

  In this case, a program corresponding to each of the setting patterns P1 to P4 is stored in advance, and when the setting patterns P1 to P4 are detected, the corresponding program is started, and each authentication corresponding to the setting patterns P1 to P4 is started. This can be handled by adopting an embodiment in which processing such as data determination is performed. In the case of the setting pattern P2, the subsequent stage unit 202B of the present embodiment has invalid data (history) in the data unit 1022 corresponding to the authentication command C1, and valid data (authentication) in the data unit 1022 corresponding to the authentication command C2. A case where it is determined that the setting patterns match if received and set in order will be described, but instead of this, an embodiment in which the order does not matter can be used.

(Processing for sending and receiving authentication information signals)
Hereinafter, an example of communication of the authentication information signal performed between the main control unit 201 and the subsequent stage unit 202B will be described. First, an example of an authentication information signal transmission procedure by the CPU 211 (first computer) of the main control unit 201 will be described with reference to a flowchart of FIG.

  When the power of the pachinko gaming machine 100 is turned on (turned on), the main control unit 201 executes an authenticated process shown in FIG. 17 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 process proceeds to step S1208. 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 sets the setting pattern set in the next setting pattern data in the data storage unit 311 as the current setting pattern, and then proceeds to the processing in step S1203. When a setting pattern is not set in the next setting pattern data, that is, in the first process, an initial setting pattern predetermined as an initial value in the pachinko gaming machine 100 is set as the current setting pattern.

  In step S1203, the main control unit 201 randomly determines the next setting pattern to be used for the next authentication of the main control unit 201 from the plurality of types of setting patterns P indicated by the pattern information D, and the determined next time Is set in the next set pattern data in the data storage unit 311, and then the process proceeds to step S <b> 1204. An example of a method for determining the next setting pattern is a method of determining using a random number.

  In step S1204, the main control unit 201 extracts an authentication value corresponding to the determined next setting pattern from the plurality of authentication values A stored in the data storage unit 311 and stores it in the RAM 213 or the like. Thereafter, the process proceeds to step S1205.

  In step S1205, the main control unit 201 sets each of a plurality of types of authentication commands corresponding to the current setting pattern in each of the identification units 1021 of the plurality of types of authentication information 1020, and each of the plurality of types of authentication commands. In the data section 1022 corresponding to the authentication data, the valid data that is the authentication value or the invalid data that is the history data stored in the data storage section 311 is set to match the current setting pattern, and a plurality of types of authentication information 1020 are set. Is stored in the data storage unit 311 or the like, and then the process proceeds to step S1206.

  When the setting pattern indicates only one of valid and invalid, only the authentication value or history data is set in the plural types of authentication information 1020. When the setting pattern defines the order of the plurality of types of authentication information 1020, the main control unit 201 generates a plurality of types of authentication information 1020 so that the order is the same. Further, when generating multiple types of authentication information 1020 in an irregular order, for example, the multiple types of authentication information 1020 are generated so that the order of the multiple types of authentication commands C1 to C5 is switched. Further, when a plurality of valid authentication values are set in the plurality of types of authentication information 1020, the authentication value set in the authentication information 1020 predetermined in the pachinko gaming machine 100 is used.

  In step S1206, the main control unit 201 encrypts the generated plurality of types of authentication information 1020 with a predetermined encryption method with the subsequent stage unit 202B, and in step S1207, the plurality of types of encrypted information. By generating an authentication information signal based on each of the authentication information 1020 and transmitting it from the main control side transmission unit 316 to the peripheral unit 202A, the authentication information signal is transmitted to the subsequent unit 202B via the peripheral unit 202A. Thereafter, the process proceeds to step S1208. If encryption is not required between the main control unit 201 and the post-stage unit 202B, the processing in step S1206 is deleted, and a plurality of types of authentication information 1020 are transmitted as they are to the post-stage unit 202B via the peripheral unit 202A. To do.

  In step S1208, 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 (S1208: 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 (S1208: Yes), the process according to this flowchart ends.

  Next, a procedure for receiving a plurality of types of authentication information by the CPU 21 (third computer) of the rear stage unit 202B will be described with reference to the flowchart of FIG.

  When executing the authentication side processing shown in FIG. 18, the rear stage unit 202B determines whether or not the control signal is received from the main control unit 201 via the peripheral unit 202A by the rear side reception unit 331 in step S1301. When determining that the control signal is not received (S1301: No), the rear stage unit 202B proceeds to the process of step S1303.

  On the other hand, if it is determined that the control signal is received (S1301: Yes), the subsequent stage unit 202B stores the control commands included in the control signal in the subsequent stage storage unit 332 in time series in step S1302, As described above, the history data is generated based on the control command and stored in the subsequent-stage storage unit 332, and then the process proceeds to step S1303. Note that the history data can be generated by storing the control commands in time series in the process of step S1302 and generating the history data when generating the authentication information.

  In step S1303, the rear stage unit 202B determines whether the rear side reception unit 331 has received authentication information (authentication information signal) 1020 from the main control unit 201 via the peripheral unit 202A. When the latter stage unit 202B determines that the authentication information 1020 has not been received (S1303: No), the process proceeds to the process of step S1315. On the other hand, when determining that the authentication information 1020 has been received (S1303: Yes), the subsequent stage unit 202B proceeds to the process of step S1304.

  In step S1304, the latter stage unit 202B decrypts the received authentication information 1020 with a decryption method corresponding to the encryption method of the main control unit 201, extracts the authentication data from the data part 1022 of the authentication information 1020, and performs the subsequent stage. The data is stored in the side storage unit 332 and the like, and the reception counter of the rear side storage unit 332 is incremented (+1), and then the process proceeds to step S1305. If encryption is not required between the main control unit 201 and the subsequent unit 202B, the decryption process in step S1304 is deleted. In the present embodiment, a case is described in which reception of one set of authentication information described above is confirmed using a reception counter. Instead of this, for example, a different set of embodiments such as using one set of flag data is used. can do.

  In step S1305, the rear stage unit 202B compares the extracted authentication data with a plurality of expected values in the rear stage storage unit 332, and determines whether the authentication data matches the expected value. If the subsequent section 202B determines that the authentication data matches the expected value (S1305: Yes), since the authentication data is valid, it is set in the identification section 1021 of the received authentication information 1020 in step S1306. The authentication data which is the valid data set in the data part 1022 of the authentication information 1020 is set in the validity determination result information of the post-stage storage unit 332, etc. Is stored in the rear-stage storage unit 332 and the like, and then the process proceeds to step S1308. The validity determination result information has a data structure in which a plurality of authentication commands and validity / invalidity can be set as a pair of data, and when the determination for all the authentication commands is completed, a plurality of types of authentication information 1020 are obtained. The setting pattern is shown.

  On the other hand, if the latter stage unit 202B determines that the authentication data does not match the expected value (S1305: No), the authentication data is invalid data, and therefore the identification unit 1021 of the received authentication information 1020 is received in step S1307. The invalidation data indicating “invalid” is associated with the authentication command C set to “invalid” and set in the validity determination result information of the post-stage storage unit 332 or the like, and the invalid data set in the data portion 1022 of the authentication information 1020 Certain history data is stored in the subsequent storage unit 332 and the like, and then the process proceeds to step S1308.

  In step S1308, the post-stage unit 202B compares the reception counter of the post-stage storage unit 332 with the number of patterns indicated by the setting pattern (the number of authentication commands), and has received all authentication information 1020 from the main control unit 201? Determine whether or not. If the latter stage unit 202B determines that all the authentication information 1020 has not been received (S1308: No), the process proceeds to step S1315. On the other hand, if it is determined that all the authentication information 1020 has been received (S1308: Yes), the subsequent stage unit 202B clears the reception counter of the subsequent stage storage unit 332, and then proceeds to the process of step S1309.

  In step S <b> 1309, the subsequent stage unit 202 </ b> B determines whether the above-described history data matches the subsequent stage side history data stored in the subsequent stage storage unit 332, and receives it from the main control unit 201. It is determined whether or not the control command is valid. If the subsequent stage 202B determines that the history data does not match the subsequent-stage history data and the control command is not valid (S1309: No), the process proceeds to step S1313. On the other hand, if the subsequent stage unit 202B determines that the history data matches the subsequent stage side history data and the control command is valid (S1309: Yes), the process proceeds to step S1310.

  In step S1310, the rear stage unit 202B determines whether or not the determination result indicated by the validity determination result information in the rear side storage unit 332 and the like matches the current setting pattern. As an example of the determination method, the determination result of validity (authentication) / invalidity (history) corresponding to a plurality of types of authentication commands C and the validity / invalidity of the authentication command C indicated by the setting pattern completely match. It is determined whether or not. When the order of a plurality of types of authentication information 1020 is added to the authentication determination, it is determined whether or not the validity determination result information is set according to the order of the authentication command C indicated by the setting pattern.

  If the latter stage unit 202B determines that it matches the current setting pattern (S1310: Yes), in step S1311, the authentication to the main control unit 201 is established, and the latter stage authentication result data indicating the establishment of the authentication is generated and stored in the RAM 23 or the like. Then, the process proceeds to step S1312. In step S1312, the subsequent stage unit 202B identifies a setting pattern associated with an expected value that matches the authentication data determined to be valid in the current authentication process, and uses the identified setting pattern as the next setting pattern. The next set pattern data in the side storage unit 332 is set, and then the process proceeds to step S1314.

  When a plurality of valid authentication values are set as authentication data in a plurality of types of authentication information 1020, for example, the authentication information 1020 corresponding to a desired authentication command, order, etc. agreed upon between each other is set. Use the authenticated value. Also, which valid data (authentication value) in the plurality of valid authentication information 1020 is used for specifying the next setting pattern can be variously different embodiments. It is also possible to adopt an embodiment in which priority is assigned and an authentication value corresponding to an authentication command having a predetermined priority is used for the identification.

  On the other hand, if it is determined in step S1310 that it does not match the current setting pattern (S1310: No), the latter stage unit 202B determines that the authentication to the main control unit 201 is not established in step S1313, and the latter stage authentication result indicating that the authentication is not established. Data is generated and stored in the RAM 23 or the like, and then the process proceeds to step S1314.

  In step S1314, the post-stage unit 202B sets the generated post-stage authentication result data in the result unit 1032 to generate post-stage authentication result information 1030, and generates a post-stage authentication result signal to which the post-stage authentication result information 1030 is added. Transmission is performed from the rear transmission unit 336 to the peripheral unit 202A, and then the process proceeds to step S1315.

  The post-stage unit 202B determines whether or not the pachinko gaming machine 100 is powered off in step S1315. When determining that the power is not turned off (S1315: No), the rear stage unit 202B returns to the process of step S1301 and repeats a series of processes. On the other hand, if it is determined that the power is turned off (S1315: Yes), the rear stage unit 202B ends the process according to this flowchart.

  Next, a procedure for receiving various control signals, a plurality of types of authentication information signals, and a subsequent authentication result signal by the CPU 241 (second computer) of the peripheral unit 202A will be described with reference to the flowchart of FIG.

  In step S1401, the peripheral unit 202A determines whether or not the control signal 1010 has been received from the main control unit 201. If the peripheral unit 202A determines that the control signal 1010 has been received (S1401: Yes), the control signal 1010 is transferred (transmitted) from the transfer unit 351 to the subsequent stage unit 202B as it is in step S1402, and then the process of step S1403 is performed. move on. In step S1403, the peripheral unit 202A performs predetermined processing based on the control command data 1001 and the accompanying data 1002 included in the received control signal 1010, and then proceeds to processing in step S1408.

  On the other hand, if it is determined that the peripheral unit 202A has not received the control signal 1010 (S1401: No), it is determined in step S1404 whether authentication information (authentication information signal) 1020 has been received from the main control unit 201. To do. If it is determined that the authentication information 1020 has been received (S1404: Yes), the peripheral unit 202A transfers (transmits) the authentication information 1020 as it is from the transfer unit 351 to the subsequent unit 202B in step S1405, and then performs the process of step S1408. Proceed to On the other hand, when it is determined that the peripheral information 202A has not received the authentication information 1020 (S1404: No), the process proceeds to step S1406.

  In step S1406, the peripheral unit 202A determines whether or not the post-authentication result signal is received from the post-stage unit 202B based on whether or not the received signal includes the identification unit 1031. If the peripheral section 202A determines that the subsequent authentication result signal has not been received (S1406: No), the peripheral section 202A proceeds to the process of step S1408. On the other hand, if the peripheral unit 202A determines that the post-authentication result signal has been received (S1406: Yes), the process proceeds to step S1407.

  In step S1407, the peripheral unit 202A refers to the result part 1032 of the received subsequent authentication result signal, and determines whether or not the subsequent authentication result signal indicates that authentication has been established. If the peripheral unit 202A determines that the subsequent authentication result indicates that the authentication is successful (S1407: Yes), the peripheral unit 202A stores the authentication result in the RAM 243 or the like, and then proceeds to the process of step S1408.

  In step S1408, the peripheral unit 202A determines whether or not the pachinko gaming machine 100 is powered off. If it is determined that the power is not turned off (S1408: No), the peripheral unit 202A returns to the process of step S1401 and repeats a series of processes. On the other hand, when it is determined that the power source is turned off (S1408: Yes), the peripheral unit 202A ends the process according to this flowchart.

  On the other hand, if it is determined in step S1407 that the subsequent authentication result does not indicate that the authentication is successful (S1407: No), the peripheral unit 202A outputs a notification signal from, for example, the speaker 262 (see FIG. 2) or the like in step S1409. Then, the process according to this flowchart is terminated. As for the processing of the peripheral portion 202A when the subsequent authentication result does not indicate that authentication is successful, that is, when authentication is not successful, the processing of the peripheral portion 202A is continued only by outputting a notification signal. Also good.

(Example of authentication processing procedure using multiple types of authentication information)
Next, an example of a procedure for performing authentication of the main control board 310 by switching a plurality of types of setting patterns P1 to P4 using the pattern information D shown in FIG. 15 will be described with reference to the drawing of FIG. .

  In FIG. 20, the main control board 310, which is the person to be authenticated, sets a preset current setting pattern P1 from the pattern information D (S1501). The main control board 310 determines the initial setting pattern P2 as the next setting pattern, and sets the result as the next setting pattern data in the data storage unit 311 (S1502). Then, the main control board 310 extracts the authentication value A2 associated with the next setting pattern P2 from the data storage unit 311 (S1503).

  The main control board 310 sets each of the authentication commands C1, C2 in the order corresponding to the current setting pattern P1 in each of the identification units 1021 of the plurality of types of authentication information 1020, and the current setting pattern P1 is the authentication command C1. , C2 indicate invalid data setting, the history data of the data storage unit 311 which is invalid data different from the authentication value A2 is stored in the data unit 1022 corresponding to each of the authentication commands C1, C2. A plurality of types of authentication information 1020C1 and C2 that are set as authentication data and match the current setting pattern P1 are generated (S1504). Then, the main control board 310 transmits authentication information 1020C1 and C2 in which invalid data is set to both sides to the peripheral portion 202A of the peripheral board 330 (S1505).

  Thus, in the authentication processing procedure, the authentication information 1020 corresponding to each of the authentication commands C1 and C2 is represented as authentication information 1020C1 and C2, respectively. And although the case where the authentication information 1020C1 and C2 are transmitted in that order will be described, the order may be reversed.

  On the other hand, the peripheral part 202A of the peripheral board 330 transfers the authentication information 1020C1 and C2 received from the main control board 310 to the subsequent stage part 202B (S1511).

  On the other hand, when the rear stage part 202B of the peripheral board 330 receives a plurality of types of authentication information 1020C1 and C2 from the peripheral part 202A (S1521), the authentication part C1 and C2 for each authentication command C1 and C2 set for the authentication command C1 and C2 Then, it is determined whether or not the authentication data in the data unit 1022 and the plurality of expected values stored in the subsequent storage unit 332 match, and setting patterns for a plurality of types of authentication information 1020 are detected (S1522). Then, the post-stage unit 202B compares the history data set in the data part 1022 of the predetermined authentication information 1020 with the post-stage side history data of the post-stage storage unit 332 and receives it from the main control board 310. The validity of the control command is determined (S1523).

  When determining that the control command is valid, the subsequent stage unit 202B determines whether or not the determination result indicated by the validity determination result information matches the current setting pattern P1 that is the initial value, and based on the determination result Authentication of the main control board 310, generating post-authentication result information 1030 having post-authentication result data indicating the authentication result, and adding the post-authentication result information 1030 to the peripheral part of the peripheral board 330 It transmits to 202A (S1524). In this case, the post-stage unit 202B establishes authentication of the main control board 310 when both of the authentication commands C1 and C2 are invalid (history). Then, when the authentication of the main control board 310 is established, the latter stage unit 202B uses the predetermined setting pattern P2 as the next setting pattern because no authentication value is set in the authentication information 1020C1 and C2 received this time. And set in the next set pattern data in the latter storage unit 332 (S1525), and the second and subsequent authentication processes are performed.

  Further, the peripheral portion 202A of the peripheral board 330 has the control command data 1001 and accompanying data received from the main control portion 201 when the post-authentication result information 1030 received from the post-stage portion 202B indicates that authentication has been established. When the predetermined processing corresponding to 1002 can be executed and the subsequent authentication result information 1030 does not indicate that authentication has been established, a notification signal is output (S1512).

  Subsequently, the main control board 310 sets the setting pattern P2 indicated by the next setting pattern data in the data storage unit 311 as the current setting pattern P2 (S1531). Then, the main control board 310 randomly determines the next set pattern as the set pattern P3 from the pattern information D, and sets the result as the next set pattern data in the data storage unit 311 (S1532). Then, the main control board 310 extracts the authentication value A3 associated with the next setting pattern P3 from the data storage unit 311 (S1533).

  The main control board 310 sets the authentication commands C1 and C2 in the order corresponding to the current setting pattern P2 in each of the identification units 1021 of the plurality of types of authentication information 1020, and the current setting pattern P2 is the authentication command C1. , C2 indicate the setting of invalid (history) data and valid (authentication value) data, the data portion 1022 corresponding to each of the authentication commands C1, C2 has a data storage unit 311 different from the authentication value A3. The invalid data that is the history data and the valid data that is the authentication value A3 are sequentially set as authentication data to generate a plurality of types of authentication information 1020C1 and C2 that match the current setting pattern P2 (S1534). Then, the main control board 310 transmits the authentication information 1020C1 and C2 with valid data set on one side to the peripheral portion 202A of the peripheral board 330 (S1535).

  On the other hand, the peripheral part 202A of the peripheral board 330 transfers the authentication information 1020C1 and C2 received from the main control board 310 to the subsequent stage part 202B (S1541).

  On the other hand, when the rear stage section 202B of the peripheral board 330 receives a plurality of types of authentication information 1020C1 and C2 from the main control board 310 via the peripheral section 202A (S1551), it is set in the identification section 1021 of the authentication information 1020C1 and C2. For each of the authentication commands C1 and C2, it is determined whether or not the authentication data of the data unit 1022 and the plurality of expected values stored in the subsequent storage unit 332 match, and the plurality of types of authentication information 1020C1 and C2 A setting pattern is detected (S1552). Then, the post-stage unit 202B compares the history data set in the data part 1022 of the authentication information 1020C1 with the post-stage side history data of the post-stage storage unit 332, and determines the control command received from the main control board 310. The validity is determined (S1553).

  If the subsequent stage unit 202B determines that the control command is valid, whether or not the determination result indicated by the validity determination result information matches the current setting pattern P2 specified as the next setting pattern in the previous authentication process. And authenticating the main control board 310 based on the determination result, generating post-stage authentication result information 1030 having post-stage authentication result data indicating the authentication result, and adding the post-stage authentication result information 1030 The authentication result signal is transmitted to the peripheral portion 202A of the peripheral substrate 330 (S1554). In this case, the post-stage unit 202B establishes authentication of the main control board 310 when the authentication command C1 is invalid and the authentication command C2 is valid. Then, when the authentication of the main control board 310 is established, the rear stage unit 202B sets the setting pattern P3 associated with the expected value B3 of the rear side storage unit 332 that matches the authentication data (authentication value A3) determined to be valid. The identification pattern is specified and set in the next set pattern data in the latter-stage storage unit 332 (S1555), and the subsequent authentication processing is performed.

  Further, the peripheral portion 202A of the peripheral board 330 has the control command data 1001 and accompanying data received from the main control portion 201 when the post-authentication result information 1030 received from the post-stage portion 202B indicates that authentication has been established. When the predetermined processing corresponding to 1002 can be executed and the subsequent authentication result information 1030 does not indicate that authentication has been established, a notification signal is output (S1542).

  In the above-described authentication processing procedure, the case where the authentication information 1020C1 and C2 are transmitted from the main control board 310 to the peripheral board 330 in the order specified by the setting pattern P has been described. Instead, the transmission order is irregular. It may be changed to.

  According to the pachinko gaming machine 100 described above, a plurality of types of setting patterns P1 to P4 and a plurality of types of authentication values A1 to A4 are associated one-to-one, and the main control unit 201 becomes the current setting pattern P. As described above, the authentication value A corresponding to the next setting pattern P and the history data indicating the history of the control command are set to generate a plurality of types of authentication information 1020, and the plurality of types of authentication information 1020 are transferred to the subsequent stage unit 202B. Since transmission is performed via the peripheral portion 202A, the authenticity of the control command indicated by the authentication value A, the history data setting pattern P, and the history data set in each of the plurality of types of authentication information 1020 by the subsequent portion 202B. By authenticating the main control unit 201 based on the above, it becomes difficult for an unauthorized analyst to analyze a plurality of types of authentication information 1020. It is possible to detect that the control commands by and unauthorized analyst can be prevented from unauthorized use are misused later portion 202B and a peripheral portion 202A. Furthermore, since the number of setting patterns P can be increased by increasing the number of types of authentication information 1020, the authentication strength can be increased. In addition, the latter stage unit 202B identifies the setting pattern P corresponding to the authentication value A from the expected value B and sets it as the next setting pattern P, so that switching of the setting pattern P in the pachinko gaming machine 100 is an unauthorized analyst. Can be made more difficult to analyze. Further, since the rear stage unit 202B performs the authentication process for the main control unit 201 and transmits the subsequent stage authentication result to the peripheral unit 202A, the peripheral unit 202A only refers to the subsequent stage authentication result without performing the authentication process. Therefore, the processing load on the CPU 241 in the peripheral portion 202A can be reduced. Furthermore, since a plurality of types of authentication values A can be stored in advance, it is not necessary to perform complicated calculations when generating the authentication information 1020, and an increase in the processing load on the main control unit 201 can be prevented. Also, since the peripheral unit 202A transfers the control command received from the main control unit 201 to the subsequent unit 202B, and the subsequent unit 202B manages the history of control commands from the main control unit 201, the peripheral unit 202A Since control command history management is not required, it is possible to prevent an increase in processing load on the peripheral portion 202A due to improved security. In addition, since the peripheral unit 202A can transfer the control command data received from the main control unit 201 to the subsequent unit 202B and perform a predetermined process, the peripheral unit 202A and the subsequent unit 202B can perform processing simultaneously. Therefore, it is possible to prevent a delay from occurring in the predetermined processing in the peripheral portion 202B. Therefore, it is possible to prevent the data transmitted from the main control unit 201 to the peripheral unit 202A and the subsequent unit 202B from being used for illegal control and to reduce the processing load on the CPU 241 of the peripheral unit 202A without using complicated calculations. be able to. Further, even if the authentication process is complicated, it does not affect the effect process by the peripheral portion 202A, so that it is possible to improve both the security and the fun of the game.

  In the pachinko gaming machine 100 described above, since a plurality of authentication values A can be set for a plurality of types of authentication information 1020, the number of setting patterns P used between the main control unit 201 and the subsequent unit 202B is increased. Therefore, it becomes even more difficult for an unauthorized analyst to analyze a plurality of types of authentication information 1020, and an unauthorized analyst can be prevented from using the authentication information 1020 illegally, and data can be obtained by an unauthorized analyst. Can be detected by the rear-stage unit 202B. In addition, since the peripheral unit 202A only needs to refer to the subsequent authentication result without performing the authentication process, it is possible to reduce the processing added by the CPU 241 of the peripheral unit 202A.

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

  In the pachinko gaming machine 100 described above, history data can be set for all of a plurality of types of authentication information 1020. In this case, the initial setting pattern is set as the next setting pattern. Since switching analysis can be made more difficult, unauthorized use can be prevented and detection accuracy can be improved.

  In the pachinko gaming machine 100 described above, the main control unit 201 transmits the plurality of types of authentication information 1020 to the subsequent stage unit 202B via the peripheral unit 202A in the order of the plurality of types of authentication information 1020 defined by the setting pattern P. By doing so, the post-stage unit 202B authenticates the main control unit 201 based on the authentication data valid (authentication value) and invalid (history data) patterns set in each of a plurality of types of authentication information 1020 and their order. Therefore, it is possible to improve the authentication accuracy without using a complicated calculation.

  In the pachinko gaming machine 100 described above, if multiple types of authentication information 1020 generated by the main control unit 201 are transmitted in an irregular order to the subsequent stage unit 202B via the peripheral unit 202A, a plurality of unauthorized analysts can be obtained. It becomes even more difficult to analyze the type of authentication information, and it is possible to prevent an unauthorized analyst from using the authentication information illegally and to detect that the data is illegally used by the unauthorized analyst at the subsequent stage 202B. be able to.

[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, the pachinko gaming machine 100 includes the control unit 200 shown in FIG. The control unit 200 includes a main control unit 201, an effect control unit (peripheral unit) 202A, a rear stage unit 202B, and a prize ball control unit 203. As shown in FIG. 21, the pachinko gaming machine 100 includes a main control board 310 having a function as the main control unit 201, and a peripheral board 330 having the above-described effect control unit 202A and the rear stage unit 202B. Is configured. 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 312, the authentication information generation unit 315, the main control side transmission unit 316, and the selection unit 313 described above.

  The selection unit 313 corresponds to the selection unit of the present invention, and randomly selects one authentication value from a plurality of types of authentication values stored in the data storage unit 311. The selection unit 313 selects one authentication value using a random number or the like. Note that the selection unit 313 can also select a plurality of authentication values corresponding to the number of settings when the setting pattern indicates the setting of valid data in a plurality of authentication information.

  The determination unit 312 described above determines the setting pattern associated with the authentication value selected by the selection unit 313 as the next setting pattern used for the next authentication of the main control board 310, and indicates the determined setting pattern next time. The setting pattern data is stored in the data storage unit 311 or the like.

  The authentication information generation unit 315 described above generates a plurality of types of authentication information 1020 so that the authentication value selected by the selection unit 313 and the history data are set according to the previously set setting pattern. The current setting pattern determined in advance is an initial setting pattern that is a predetermined initial value in the first process of the authentication information generation unit 315, and the previous process is performed in the second and subsequent processes. The determined setting pattern is the next time. If the setting pattern indicates a plurality of valid data (authentication) settings, an authentication value associated with the next setting pattern is set in the predetermined authentication information 1020 and set in the current setting pattern. Multiple types of authentication information 1020 are generated.

  Similarly to the first embodiment, the pachinko gaming machine 100 according to the second embodiment also combines the authentication information 1020 in which a valid authentication value is set and the authentication information 1020 in which history data is set, from the main control board 310 to the peripheral board 330. Is transmitted to the subsequent stage section 202B via the peripheral section 202A, and the subsequent stage section 202B detects the setting patterns of the plurality of types of authentication information 1020, and based on the validity of the control command and the detected setting pattern, A configuration that performs authentication is adopted. Therefore, the pachinko gaming machine 100 can improve security by authenticating by combining a plurality of types of setting patterns, and it is easy to send authentication information from the main control unit 201 to the peripheral board 330 alone. Can be difficult to analyze.

  Subsequently, the peripheral portion 202A of the peripheral substrate 330 illustrated in FIG. 21 includes the transfer unit 351, the peripheral side receiving unit 352, and the processing unit 353 described above, as in the first embodiment. Similarly to the first embodiment, the rear stage unit 202B also includes the rear stage side reception unit 331, the rear stage side storage unit 332, the setting pattern detection unit 333, the validity determination unit 334, the rear stage authentication result data generation unit 335, and the rear stage side. A transmission unit 336 and a specifying unit 337 are included. As described above, the peripheral substrate 330 can be realized by the same configuration as that of the first embodiment, and thus the description thereof is omitted.

  Also in the second embodiment, the CPU 211 of the main control board 310 is the first computer in the claims, and the CPU 241 of the peripheral part (effect control unit) 202A of the peripheral board 330 is the second computer in the claims of the peripheral board 330. A case will be described in which the CPU 21 of the rear stage unit 202B functions as the third computer in the claims. The ROM 212 of the main control board 310 is a main control side authentication program for causing the first computer to function as various means such as selection means, authentication information generation means, main control side transmission means, and determination means in the claims. Is remembered. The ROM 242 of the peripheral portion 202A of the peripheral board 330 stores a peripheral side authentication program for causing the second computer to function as various means such as transfer means, peripheral side receiving means, and processing means. Yes. Further, the ROM 22 of the rear stage 202B of the peripheral board 330 includes various types of the third computer, such as a rear side receiving means, a setting pattern detecting means, a validity determining means, a subsequent authentication result data generating means, and a specifying means. A post-stage authentication program for functioning as a means is stored. That is, the authentication program of the present invention is constituted by the main control side authentication program, the peripheral side authentication program, and the subsequent stage side authentication program.

(Processing for sending and receiving authentication information signals)
Hereinafter, an example of communication of the authentication information signal performed between the main control unit 201 and the subsequent stage unit 202B will be described. 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 in step S1601 whether or not it is a predetermined authentication timing. If the main control unit 201 determines that it is not the authentication timing (S1601: No), the main control unit 201 proceeds to the process of step S1608. On the other hand, if the main control unit 201 determines that it is the authentication timing (S1601: Yes), the process proceeds to step S1602.

  In step S1602, the main control unit 201 sets the setting pattern set in the next setting pattern data in the data storage unit 311 as the current setting pattern, and then proceeds to the processing of step S1603. When a setting pattern is not set in the next setting pattern data, that is, in the first process, an initial setting pattern predetermined as an initial value in the pachinko gaming machine 100 is set as the current setting pattern.

  In step S1603, the main control unit 201 selects one authentication value from among a plurality of types of expected values stored in the data storage unit 311 using a random number or the like and stores it in the RAM 213 or the like, and then in step S1604. Proceed to processing. In this flowchart, the case where one authentication value is selected is described for the sake of simplification of description, but a configuration in which a plurality of authentication values are selected may be used instead.

  In step S1604, the main control unit 201 sets each of a plurality of types of authentication commands corresponding to the current setting pattern in each of the identification units 1021 of the plurality of types of authentication information 1020, and each of the plurality of types of authentication commands. In the data section 1022 corresponding to the above, the valid data that is the selected authentication value and the invalid data that is the history data stored in the data storage section 311 are set so as to match the current setting pattern, and a plurality of types The authentication information 1020 is generated and stored in the data storage unit 311 and the like, and then the process proceeds to step S1605.

  When the setting pattern defines the order of the plurality of types of authentication information 1020, the main control unit 201 generates the plurality of types of authentication information 1020 so that the order is the same. Further, when generating multiple types of authentication information 1020 in an irregular order, for example, the multiple types of authentication information 1020 are generated so that the order of the multiple types of authentication commands C1 to C5 is switched. Further, when a plurality of valid authentication values are set in the plurality of types of authentication information 1020, at least an authentication value is set in the authentication information 1020 predetermined in the pachinko gaming machine 100.

  In step S1605, the main control unit 201 encrypts the generated plurality of types of authentication information 1020 with a predetermined encryption method with the subsequent unit 202B, and in step S1606, the plurality of types of encrypted information. An authentication information signal is generated based on each of the authentication information 1020 and transmitted from the main control side transmission unit 316 to the rear stage unit 202B via the peripheral unit 202A, and then the process proceeds to step S1607. If encryption is not required between the main control unit 201 and the subsequent unit 202B, the processing in step S1605 is deleted and a plurality of types of authentication information 1020 are transmitted to the peripheral unit 202A as they are.

  In step S1607, the main control unit 201 specifies a setting pattern corresponding to the selected authentication value from among a plurality of types of setting patterns P indicated by the pattern information D, and the specified setting pattern is stored in the main control unit 201. The next set pattern data in the data storage unit 311 is set as the next set pattern to be used for the next authentication, and then the process proceeds to step S1608.

  In step S1608, the main control unit 201 determines whether or not the pachinko gaming machine 100 is turned off. If the main control unit 201 determines that the power is not turned off (S1608: No), the main control unit 201 returns to the process of step S1601 and repeats a series of processes. On the other hand, when the main control unit 201 determines that the power is turned off (S1608: Yes), the process according to this flowchart ends.

  Subsequently, the control signal and the subsequent authentication result signal received by the CPU 241 (second computer) in the peripheral portion 202A of the peripheral board 330, and the authentication performed by the CPU 21 (third computer) in the rear portion 202B. The procedure of the information signal reception process can use the process shown in FIG. 19 of the first embodiment and the authentication-side process shown in FIG. 18 as they are, and detailed description thereof will be omitted.

(Example 2 of authentication processing procedure using multiple types of authentication information)
Next, referring to the drawing of FIG. 23, an example of the processing procedure 2 in the case of performing authentication of the main control board 310 by switching a plurality of types of setting patterns P1 to P4 using the pattern information D shown in FIG. explain.

  In FIG. 23, the main control board 310 that is the person to be authenticated sets a preset current setting pattern P2 from the pattern information D (S1701). Then, the main control board 310 randomly extracts one authentication value A2 from a plurality of types of authentication values A1 to A4 (S1702).

  The main control board 310 sets the authentication commands C1 and C2 in the order corresponding to the current setting pattern P2 in each of the identification units 1021 of the plurality of types of authentication information 1020, and the current setting pattern P2 is the authentication command C1. , C2 indicate invalid data and valid data settings, the invalid data and authentication value A2 that are the history data different from the authentication value A2 are stored in the data portion 1022 corresponding to each of the authentication commands C1 and C2. Are sequentially set as authentication data, and a plurality of types of authentication information 1020C1 and C2 matching the current setting pattern P2 are generated (S1703). Then, the main control board 310 transmits authentication information 1020C1 and C2 in which valid data is set on one side to the peripheral portion 202A of the peripheral board 330 (S1704). Then, the main control board 310 determines the setting pattern P2 associated with the selected authentication value A2 as the next setting pattern used for the next authentication of the main control board 310, and the result is the next time in the data storage unit 311. The setting pattern data is set (S1705). That is, the main control board 310 continues to use the setting pattern P2 in the next authentication process.

  Thus, in the authentication processing procedure, the authentication information 1020 corresponding to each of the authentication commands C1 and C2 is represented as authentication information 1020C1 and C2, respectively. And although the case where the authentication information 1020C1 and C2 are transmitted in that order will be described, the order may be reversed.

  On the other hand, the peripheral part 202A of the peripheral board 330 transfers the authentication information 1020C1 and C2 received from the main control board 310 to the subsequent stage part 202B (S1711).

  On the other hand, when the rear stage unit 202B of the peripheral board 330 receives a plurality of types of authentication information 1020C1 and C2 from the peripheral unit 202A (S1721), for each authentication command C1 and C2 set in the identification unit 1021 of the authentication information 1020C1 and C2 Then, it is determined whether or not the authentication data in the data unit 1022 and the plurality of expected values stored in the subsequent storage unit 332 match, and setting patterns for a plurality of types of authentication information 1020 are detected (S1722). Then, the rear stage unit 202B compares the history data set in the data part 1022 of the authentication information 1020C1 in which invalid data is set with the peripheral side history data of the rear stage storage unit 332 and receives it from the main control board 310. The validity of the control command being performed is determined (S1723).

  When determining that the control command is valid, the subsequent stage unit 202B determines whether or not the determination result indicated by the validity determination result information matches the current setting pattern P2 that is the initial value, and based on the determination result Authentication of the main control board 310, generating post-authentication result information 1030 having post-authentication result data indicating the authentication result, and adding the post-authentication result information 1030 to the peripheral part of the peripheral board 330 It transmits to 202B (S1724). In this case, the post-stage unit 202B establishes authentication of the main control board 310 when the authentication command C1 is invalid and the authentication command C2 is valid. Then, the post-stage unit 202B identifies the setting pattern P2 associated with the expected value B2 of the post-stage storage unit 332 that matches the authentication data (authentication value A2) determined to be valid, and the next setting of the post-stage storage unit 332 The pattern data is set (S1725), and the second and subsequent authentication processes are performed.

  Further, the peripheral portion 202A of the peripheral board 330 has the control command data 1001 and accompanying data received from the main control portion 201 when the post-authentication result information 1030 received from the post-stage portion 202B indicates that authentication has been established. When the predetermined processing corresponding to 1002 can be executed and the subsequent authentication result information 1030 does not indicate that authentication has been established, a notification signal is output (S1712).

  Subsequently, the main control board 310 sets the setting pattern P2 indicated by the next setting pattern data in the data storage unit 311 as the current setting pattern P2 (S1731). Then, the main control board 310 randomly extracts one authentication value A4 from a plurality of types of authentication values A1 to A4 (S1732).

  The main control board 310 sets the authentication commands C1 and C2 in the order corresponding to the current setting pattern P2 in each of the identification units 1021 of the plurality of types of authentication information 1020, and the current setting pattern P2 is the authentication command C1. , C2 indicate invalid data and valid data settings, so that the data portion 1022 corresponding to each of the authentication commands C1 and C2 is different from the authentication value A4 with the invalid data and the authentication value A4 that are history data. Certain valid data is sequentially set as authentication data, and a plurality of types of authentication information 1020C1 and C2 matching the current setting pattern P2 are generated (S1733). Then, the main control board 310 transmits authentication information 1020C1 and C2 in which valid data is set on one side to the peripheral portion 202A of the peripheral board 330 (S1734). Then, the main control board 310 determines the setting pattern P4 associated with the selected authentication value A4 as the next setting pattern to be used for the next authentication of the main control board 310, and the result is the next time in the data storage unit 311. The setting pattern data is set (S1735). That is, in the next authentication process, the setting pattern P2 is switched to the setting pattern P4.

  On the other hand, the peripheral part 202A of the peripheral board 330 transfers the authentication information 1020C1 and C2 received from the main control board 310 to the subsequent stage part 202B (S1741).

  On the other hand, when the rear stage section 202B of the peripheral board 330 receives a plurality of types of authentication information 1020C1 and C2 from the main control board 310 (S1751), each authentication command C1 and C2 set in the identification section 1021 of the authentication information 1020C1 and C2 In addition, it is determined whether or not the authentication data of the data unit 1022 and the plurality of expected values stored in the subsequent storage unit 332 match, and setting patterns for a plurality of types of authentication information 1020C1 and C2 are detected ( S1752). Then, the post-stage unit 202B compares the history data set in the data part 1022 of the authentication information 1020C1 with the post-stage side history data of the post-stage storage unit 332, and determines the control command received from the main control board 310. The validity is determined (S1753).

  If the subsequent stage unit 202B determines that the control command is valid, whether or not the determination result indicated by the validity determination result information matches the current setting pattern P2 specified as the next setting pattern in the previous authentication process. And authenticating the main control board 310 based on the determination result, generating post-stage authentication result information 1030 having post-stage authentication result data indicating the authentication result, and adding the post-stage authentication result information 1030 The authentication result signal is transmitted to the peripheral portion 202B of the peripheral substrate 330 (S1754). Then, when the authentication of the main control board 310 is established, the subsequent stage unit 202B sets the setting pattern P4 associated with the expected value B4 of the rear side storage unit 332 that matches the authentication data (authentication value A4) determined to be valid. Then, the next setting pattern data in the subsequent storage unit 332 is specified (S1755), and the subsequent authentication processing is performed.

  Further, the peripheral portion 202A of the peripheral board 330 has the control command data 1001 and accompanying data received from the main control portion 201 when the post-authentication result information 1030 received from the post-stage portion 202B indicates that authentication has been established. When the predetermined processing corresponding to 1002 can be executed and the subsequent authentication result information 1030 does not indicate that authentication has been established, a notification signal is output (S 1742).

  In the authentication processing procedure 2 described above, the case where the authentication information 1020C1 and C2 are transmitted from the main control board 310 to the peripheral board 330 in the order defined by the setting pattern P has been described. It may be changed to a rule.

  According to the pachinko gaming machine 100 described above, a plurality of types of setting patterns P1 to P4 and a plurality of types of authentication values A1 to A4 are associated one-to-one, and the main control unit 201 becomes the current setting pattern P. As described above, the authentication value A corresponding to the next setting pattern P and the history data indicating the history of the control command are set to generate a plurality of types of authentication information 1020, and the plurality of types of authentication information 1020 are transferred to the subsequent stage unit 202B. Since transmission is performed via the peripheral portion 202A, the authenticity of the control command indicated by the authentication value A, the history data setting pattern P, and the history data set in each of the plurality of types of authentication information 1020 by the subsequent portion 202B. By authenticating the main control unit 201 based on the above, it becomes difficult for an unauthorized analyst to analyze a plurality of types of authentication information 1020. It is possible to detect that the control commands by and unauthorized analyst can be prevented from unauthorized use are misused later portion 202B and a peripheral portion 202A. Furthermore, since the number of setting patterns P can be increased by increasing the number of types of authentication information 1020, the authentication strength can be increased. In addition, the latter stage unit 202B identifies the setting pattern P corresponding to the authentication value A from the expected value B and sets it as the next setting pattern P, so that switching of the setting pattern P in the pachinko gaming machine 100 is an unauthorized analyst. Can be made more difficult to analyze. Further, since the rear stage unit 202B performs the authentication process for the main control unit 201 and transmits the subsequent stage authentication result to the peripheral unit 202A, the peripheral unit 202A only refers to the subsequent stage authentication result without performing the authentication process. Therefore, the processing load on the CPU 241 in the peripheral portion 202A can be reduced. Furthermore, since a plurality of types of authentication values A can be stored in advance, it is not necessary to perform complicated calculations when generating the authentication information 1020, and an increase in the processing load on the main control unit 201 can be prevented. Also, since the peripheral unit 202A transfers the control command received from the main control unit 201 to the subsequent unit 202B, and the subsequent unit 202B manages the history of control commands from the main control unit 201, the peripheral unit 202A Since control command history management is not required, it is possible to prevent an increase in processing load on the peripheral portion 202A due to improved security. In addition, since the peripheral unit 202A can transfer the control command data received from the main control unit 201 to the subsequent unit 202B and perform a predetermined process, the peripheral unit 202A and the subsequent unit 202B can perform processing simultaneously. Therefore, it is possible to prevent a delay from occurring in the predetermined processing in the peripheral portion 202B. Therefore, it is possible to prevent the data transmitted from the main control unit 201 to the peripheral unit 202A and the subsequent unit 202B from being used for illegal control and to reduce the processing load on the CPU 241 of the peripheral unit 202A without using complicated calculations. be able to. Further, even if the authentication process is complicated, it does not affect the effect process by the peripheral portion 202A, so that it is possible to improve both the security and the fun of the game.

  In the pachinko gaming machine 100 described above, since a plurality of authentication values A can be set for a plurality of types of authentication information 1020, the number of setting patterns P used between the main control unit 201 and the subsequent unit 202B is increased. Therefore, it becomes even more difficult for an unauthorized analyst to analyze a plurality of types of authentication information 1020, and an unauthorized analyst can be prevented from using the authentication information 1020 illegally, and data can be obtained by an unauthorized analyst. Can be detected by the rear-stage unit 202B. In addition, since the peripheral unit 202A only needs to refer to the subsequent authentication result without performing the authentication process, it is possible to reduce the processing added by the CPU 241 of the peripheral unit 202A.

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

  In the pachinko gaming machine 100 described above, history data can be set for all of a plurality of types of authentication information 1020. In this case, the initial setting pattern is set as the next setting pattern. Since switching analysis can be made more difficult, unauthorized use can be prevented and detection accuracy can be improved.

  In the pachinko gaming machine 100 described above, the main control unit 201 transmits the plurality of types of authentication information 1020 to the subsequent stage unit 202B via the peripheral unit 202A in the order of the plurality of types of authentication information 1020 defined by the setting pattern P. By doing so, the post-stage unit 202B authenticates the main control unit 201 based on the authentication data valid (authentication value) and invalid (history data) patterns set in each of a plurality of types of authentication information 1020 and their order. Therefore, it is possible to improve the authentication accuracy without using a complicated calculation.

  In the pachinko gaming machine 100 described above, if multiple types of authentication information 1020 generated by the main control unit 201 are transmitted in an irregular order to the subsequent stage unit 202B via the peripheral unit 202A, a plurality of unauthorized analysts can be obtained. It becomes even more difficult to analyze the type of authentication information, and it is possible to prevent an unauthorized analyst from using the authentication information illegally and to detect that the data is illegally used by the unauthorized analyst at the subsequent stage 202B. be able to.

  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, etc., 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.
