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 the regular main control board and the controlled board, There has been a problem that it is not possible to prevent unauthorized control by an unauthorized control signal that is output.

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

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

Further, when the third computer at the rear stage receives the authentication information from the main control unit, two expected values indicate whether the generation method of the authentication data of the authentication information matches a predetermined current generation method. It is possible to generate the latter authentication result data indicating the authentication result of the main control unit based on the determination result and transmit it to the peripheral part. When the authentication of the main control unit is established, the third computer specifies the generation method associated with the expected value that matches the inspection value constituting the authentication data as the next generation method, and the subsequent generation method information The subsequent generation method information stored in the storage means can be updated to indicate the next generation method. On the other hand, the second computer in the peripheral part can perform a predetermined process in the gaming machine based on the control command received from the main control part, according to the latter authentication result data received from the latter part.

An authentication program for a gaming machine according to a thirteenth aspect of the present invention includes a main control unit that transmits a control command, a peripheral unit that performs predetermined processing based on the control command transmitted by the main control unit, and the main control unit. An authentication program for a gaming machine comprising a subsequent stage for performing authentication of the control unit, wherein the first computer of the main control unit and authentication data used by the peripheral unit for authentication of the main control unit are determined in advance. The inspection value storage means is associated with two predetermined generation methods in a one-to-one manner from among three or more generation methods for generating arbitrarily using at least one of the obtained inspection value and other values. Based on at least one of the selected inspection value and the other value, a selection unit that randomly selects one inspection value from two different inspection values stored by the generation method information storage unit Memory Authentication data generating means for generating the authentication data of the current generation method indicated by the generated generation method information, authentication information generating means for generating authentication information having the generated authentication data, and the generated authentication information The main control-side transmitting means for transmitting to the subsequent stage unit via the peripheral unit, and the generation method associated with the selected inspection value is determined as the next generation method, and the next generation method is indicated. Functioning as a determination unit that updates the generation method information in the generation method information storage unit, the third computer in the rear stage unit, the rear side reception unit that receives the authentication information from the main control unit, and the received authentication whether the current generation method indicated by the second-stage generation method information stored in the second-stage generation method information storing means of the second part and the generation method of the authentication data of the information matches, the two Each and using the matched and the two kinds of the two expected value expected value storage means of the second part as each and two expected value associated with the one-to-one is stored in the method of generating the test values A post-stage authentication result data generating means for generating post-stage authentication result data indicating the authentication result of the main control unit based on the determination result, and a post-stage side for transmitting the generated post-stage authentication result data to the peripheral unit When the authentication of the transmission means and the main control unit is established, the generation method associated with the expected value that matches the inspection value constituting the authentication data is identified as the next generation method and the subsequent stage Functioning as a specifying means for updating the side generation method information, the second computer in the peripheral part, a transfer means for transferring the authentication information received from the main control part to the succeeding part, and a succeeding part recognition from the succeeding part. A game machine authentication program for causing a peripheral side receiving means for receiving test result data and a processing means for performing the predetermined processing based on the control command in accordance with the received post-authentication result data.

  According to the gaming machine authentication program of the present invention described in claim 13, when the first computer of the main control unit randomly selects one inspection value from the two inspection values in the inspection value storage means, Based on at least one of the selected inspection value and another value, the generation method authentication data indicated by the generation method information stored in the generation method information storage means is generated. The first computer can generate authentication information having the generated authentication data, and can transmit the generated authentication information to the subsequent stage part via the peripheral part. The first computer can determine the generation method associated with the selected inspection value as the next generation method, and update the generation method information in the generation method information storage means to indicate the next generation method. . On the other hand, the second computer in the peripheral part transfers the authentication information received from the main control part to the subsequent part. Further, when the third computer at the rear stage receives the authentication information from the main control unit, two expected values indicate whether the generation method of the authentication data of the authentication information matches a predetermined current generation method. It is possible to generate the latter authentication result data indicating the authentication result of the main control unit based on the determination result and transmit it to the peripheral part. When the authentication of the main control unit is established, the third computer specifies the generation method associated with the expected value that matches the inspection value constituting the authentication data as the next generation method, and the subsequent generation method information The subsequent generation method information stored in the storage means can be updated to indicate the next generation method. On the other hand, the second computer in the peripheral part can perform a predetermined process in the gaming machine based on the control command received from the main control part, according to the latter authentication result data received from the latter part.

  As described above, according to the present invention, two inspection values are associated with two predetermined generation methods from among three or more generation methods of authentication data, and the main control side generates the next generation method. Generates authentication data for the current generation method using at least one of the inspection value corresponding to the method and other values, generates authentication information having the authentication data, and transmits it to the subsequent stage via the peripheral unit Since the latter part can specify the authentication data generation method based on two expected values that match the two inspection values on the main control side, the authentication data generation method and the inspection value can be specified. By performing authentication on the main control side based on the above, it is possible to prevent an unauthorized analyst from using authentication information illegally. In addition, when the authentication on the main control side is established, the latter part specifies the next generation method based on the inspection value of the authentication data, so an unauthorized analyst analyzes the authentication information. Since it becomes difficult and the peripheral side can detect based on the next generation method that the authentication data has been used illegally by an unauthorized analyst, the authentication strength of the authentication information can be increased. Moreover, since two types of generation methods can be selectively used from three or more types, a plurality of combination patterns of two types of generation methods can be used even in the same series of gaming machines. Since the combination pattern of the types of generation methods can be used instead, the authentication information can be made versatile. 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 the two inspection values can be stored in advance, it is not necessary to perform a complicated calculation when generating the authentication information, and an increase in processing load on the main control side can be prevented. In addition, since the latter part transmits the control command from the main control side to the peripheral side as it is, the latter part can perform the authentication process and the peripheral side can perform the predetermined process. A delay in processing can be prevented. Therefore, the authentication information can be made to be versatile by making it difficult to analyze the authentication information illegally.

  In the above-described gaming machine, since the generation methods corresponding to each of the inspection value, the composite value, and the dummy data are used as the three or more types of generation methods, it becomes even more difficult for the fraud analyst to analyze the authentication data. be able to. Since other values corresponding to the second generation method can use a plurality of types of data, it is possible to increase the number of types of generation methods, making the analysis of authentication data and the generation method even more difficult. can do.

  In the gaming machine described above, since the other value of the second generation method is used as the history data of the control command, the history data is a value that changes according to the transmission of the control command. The authentication data to be generated is a variable value, which can make analysis by an unauthorized analyst even more difficult. In addition, since it is possible to determine whether or not the control command histories of both the main control side and the latter part match, the latter part performs authentication on the main control side taking into account the legitimacy of the control command. Can do.

  In the gaming machine described above, since the history data and the subsequent-stage history data indicate the history of the control command for a plurality of times, even if the number of authentication information transmissions is reduced, the control command fraud that occurred during that time is detected. Therefore, it is possible to improve the authentication accuracy. 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 gaming machine described above, if the latter part cannot extract the inspection value from the authentication data, the predetermined generation method is specified as the next generation method, and one of the two generation methods is determined as the inspection value. Since it is possible to generate only with different data, it is possible to make it difficult for an unauthorized analyst to analyze two types of test values, so that unauthorized use of authentication information can be prevented and detection accuracy can be improved. it can.

Various embodiments such as a configuration to be connected can be used.

(Functional configuration of main control board and peripheral board)
First, a functional configuration of the main control board 310 having a function as the main control unit 201 will be described with reference to FIG. The main control board 310 is a functional unit that transmits a control command for operating the peripheral board 330, and includes a data storage unit 311, a determination unit 312, an authentication data generation unit 314, an authentication information generation unit 315, and a main control side transmission. A portion 316 is included. 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 the inspection value storage means and history data storage means of the present invention, and stores various data such as control command data, history data, generation method information, and two types of inspection values. As the data storage unit 311, for example, a part of the ROM 212 and the RAM 213 (see FIG. 2) of the main control unit 201 can be used. The data storage unit 311 has a storage area for storing authentication information transmitted to the peripheral unit. The authentication information stored in the data storage unit 311 can have various different embodiments such as a configuration for storing only one transmission, and a configuration for storing a plurality of transmissions in time series.

  The data storage unit 311 arbitrarily uses at least one of a predetermined inspection value and other values as authentication data used by the rear stage unit 202B of the peripheral substrate 330 for authentication of the main control board 310 (main control unit). Among the three or more types of generation methods that are generated in this manner, two different inspection values associated with two predetermined generation methods in a one-to-one manner are stored. The two inspection values are determined in accordance with two generation methods determined at the time of design or the like for the pachinko gaming machine 100, and are stored in the data storage unit 311 at the time of manufacturing the pachinko gaming machine 100 or the like. Each of the two inspection values is different data, for example, a checksum of two different predetermined areas in the ROM 212 of the main control unit 201, a predetermined unique value, and the like. The three types of generation methods will be described later.

  The data storage unit 311 stores history data indicating a history of control commands transmitted from the main control board 310 to the peripheral board 330. The history data is updated by history data generation 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 determination unit 312 corresponds to a determination unit of the present invention, and randomly determines the next generation method of the authentication data to be used for the next authentication of the main control board 310 from the two generation methods. The next generation method is set in the generation method information and stored in the data storage unit 311 or the like. The determination unit 312 randomly determines the next generation method using a random number or the like, thereby making it difficult for the fraud analyst to analyze it illegally.

  The authentication data generation unit 314 corresponds to the authentication data generation unit of the present invention, and is determined based on at least one of the inspection value associated with the next generation method determined by the determination unit 312 and another value. The unit 312 generates authentication data for the generation method determined last time, that is, the generation method indicated by the generation method information. For example, the authentication data generation unit 314 randomly generates a plurality of types of data as authentication data, such as only the inspection value, a combined value of the inspection value and another value, and other values. Then, the authentication data generation unit 314 generates authentication data by using an initial generation method that is a predetermined initial value in the first process, and in the second and subsequent processes, the determination unit is determined in the previous process. Since the next generation method is determined in 312, the next generation method is used as the current generation method to generate authentication data. In addition, although the case where the other value in the present embodiment is the above-described history data will be described, instead of this, for example, a variable value such as the number of transmissions of control commands and authentication information in the pachinko gaming machine 100, the inspection It may be a predetermined fixed value different from the value.

  The authentication information generation unit 315 corresponds to the authentication information generation unit of the present invention, and generates authentication information having the authentication data generated by the authentication data generation unit 314. The authentication information generation unit 315 according to the present embodiment will be described for the case of generating authentication information having authentication data and an authentication command different from the control command, but instead, authentication information having only authentication data and You can also As described above, in the authentication information, one of the authentication data generated by the authentication data generation unit 314 is set irregularly.

  The main control side transmission unit 316 corresponds to the main control side transmission unit of the present invention, and the authentication information generated by the authentication information generation unit 315 and the control command data for controlling the peripheral unit 202A are transmitted to the peripheral unit of the peripheral substrate 330. The data is transmitted to the rear stage 202B via 202A. The main control side transmission unit 316 of the present embodiment transmits the control command data to the peripheral portion 202A of the peripheral substrate 330 as a control signal. Further, the main control side transmission unit 316 transmits the authentication information as an authentication information signal that is a signal different from the control signal, to the subsequent stage unit 202B via the peripheral unit 202A. Thereby, in pachinko gaming machine 100, the control signal and the authentication information signal are differentiated.

  In the pachinko gaming machine 100 of the present invention, two types of generation methods are determined in advance from among three or more types of generation methods at the time of design, etc., and a program for performing processing corresponding thereto and two inspection values are stored in the main control board 310. Is stored in advance in the data storage unit 311 at the time of manufacture. Then, the pachinko gaming machine 100 generates authentication data for one of the two generation methods using at least one of the inspection value and the other value, and generates authentication information having the authentication data. The main control board 310 transmits data to the rear stage part 202B of the peripheral board 330 via the peripheral part 202A, and the rear stage part 202B adopts a configuration in which the main control board 310 is authenticated based on the authentication data generation method. Yes. Therefore, the pachinko gaming machine 100 can make it difficult to illegally analyze the authentication data even if one kind of authentication information is used, so that security is improved and the authentication information is versatile. Can be made.

  Next, a functional configuration of the peripheral board 330 having a function as a peripheral part such as the above-described effect control unit 202A will be described. As shown in FIG. 3, the peripheral board 330 includes a peripheral part (effect control part) 202 </ b> A and a rear stage part 202 </ b> B. And the peripheral board | substrate 330 is comprised so that bidirectional | two-way communication is possible between the peripheral part (effect control part) 202A and the back | latter stage part 202B. In this embodiment, the peripheral board 330 having the production control unit 202A and the rear stage part 202B will be described, but instead, a peripheral board provided with the rear stage part 202B on the prize ball control unit 203 side. You can also

  First, the post-stage unit 202B includes a post-stage reception unit 331, a post-stage storage unit 332, a post-stage authentication result data generation unit 333, a post-stage transmission unit 334, and a specification unit 335.

  The post-stage receiving unit 331 corresponds to the post-stage receiving unit of the present invention, and the main control board 310 transmits authentication information and the like transmitted from the peripheral unit 202A to the peripheral unit 202A. The rear-stage receiving unit 331 of the present embodiment receives the authentication information from the main control board 310 via the peripheral unit 202A, for example, by receiving an authentication information signal corresponding to the authentication information. Further, the rear receiving unit 331 receives the control signal transferred from the peripheral unit 202A separately from the authentication information signal.

  The post-stage storage unit 332 corresponds to the expected value storage means, the post-stage generation method information storage means, and the post-stage history data storage means of the present invention. The post-stage storage unit 332 has two expectation values that coincide with each of the two inspection values to be received from the main control board 310, that is, the two inspection values stored in the data storage unit 311 of the main control board 310. The value is memorized. As a result, if the expected value matches the authentication data set in the authentication information, the rear stage portion 202B of the peripheral substrate 330 can determine that the authentication data is a normal inspection value. If the authentication data does not match the expected value, it can be determined that the authentication data is not an inspection value.

  The rear-stage storage unit 332 stores each of the plurality of expected values in a one-to-one correspondence with each of the two types of generation methods used in the main control board 310. For example, the peripheral storage unit 332 stores generation method identification data indicating two types of generation methods in association with expected values, thereby specifying the generation method from the expected value.

  The latter-stage storage unit 332 stores latter-stage generation method information indicating the current generation method. The latter generation method information includes the next generation method data indicating the next generation method used for the next generation of the authentication data specified based on the expected value that matches the inspection value. It is updated by the specifying unit 335 described later.

  The post-stage storage unit 332 stores a plurality of control command data received from the main control unit 201 in time series, and stores post-stage history data indicating the history of the received control command data. The rear stage 202B of the peripheral board 330 has rear stage history data generation means for generating rear stage history data by the same generation method as the history data generation means of the main control board 310, and the rear stage storage section 332 The latter-stage history data is updated by the latter-stage history data generating means at a timing corresponding to the update timing of the main control board 310. Therefore, if only the control command data transmitted from the main control board 310 is received, the latter-stage history data matches the history data on the main control side. Can be determined to be received.

  The post-authentication result data generation unit 333 corresponds to post-authentication result data generation means of the present invention. The authentication data generation method of the authentication information received by the post-stage reception unit 331 is a post-stage storage unit (post-stage side generation method). Information storage means) 332 that uses the two expected values to determine whether or not it matches the current generation method indicated by the subsequent generation method information of the 332, and the latter part that indicates the authentication result of the main control board 310 based on the determination result. Generate authentication result data. 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).

  As an example of the authentication method of the latter-stage authentication result data generation unit 333, it is determined whether or not the authentication data of the authentication information matches the expected value, the determination result matches the expected value, and the determination result If the specified current generation method matches the generation method specified in advance in the previous process, the authentication information of the main control board 310 is established because the authentication information is valid. If the authentication data does not match the expected value, or if the authentication data generation method does not match, the authentication information is not legitimate, and the authentication of the main control board 310 is not established. . As another authentication method, an authentication data generation method is analyzed using authentication data for authentication information and two expected values, and whether or not the generated generation method matches the current generation method. If they match, authentication is established, and if they do not match, authentication is not established. As described above, by authenticating the main control board 310 based on the validity of the inspection value and the generation method, it is possible to improve the strength of the security compared to performing authentication only by checking the inspection value. Further, as another authentication method, an embodiment in which authentication of the main control board 310 is performed by paying attention to any one of whether the inspection value and the expected value are the same, the generation method is the same, or the like. You can also

  The post-stage transmission unit 334 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 333 to the peripheral unit 202A. Then, the post-stage transmission unit 334 transmits the generated post-stage authentication result data to the peripheral unit 202A as a post-stage authentication result signal, for example.

  The specifying unit 335 corresponds to the specifying unit of the present invention. When the authentication of the main control board 310 is established by the post-authentication result data generation unit 333, the specifying unit 335 is associated with the expected value that matches the inspection value constituting the authentication data. The generated generation method is specified as the next generation method, and the subsequent generation method information stored in the subsequent storage unit 332 is updated so as to be the specified next generation method.

  Next, the peripheral unit 202A includes a transfer unit 351, a peripheral side reception unit 352, and a processing unit 353.

  The transfer unit 351 corresponds to a transfer unit of the present invention, receives authentication information and control command data from the main control board 310, and transfers the received authentication information and control command to the subsequent stage unit 202B. For example, when receiving the authentication information signal and the control signal corresponding to the authentication information from the main control board 310, the transfer unit 351 of the present embodiment transmits the authentication information signal and the control signal to the subsequent unit 202B as they are. The authentication information and control command data are transferred to the subsequent stage unit 202B. Note that, when there is no need to monitor the history of the control command data in the subsequent stage unit 202B, the transfer unit 351 transfers only the received authentication information to the subsequent stage unit 202B and does not transfer the control command data. You can also

  The peripheral side receiving unit 352 corresponds to the peripheral side receiving means of the present invention, and receives the post-stage authentication result data and the like transmitted by the post-stage part 202B of the peripheral board 330. Then, the peripheral side reception unit 352 of the present embodiment receives the post-stage authentication result data from the post-stage unit 202B, for example, by receiving a post-stage authentication result signal (described later) transmitted by the post-stage unit 202B.

  The processing unit 353 corresponds to the processing means of the present invention, and performs predetermined processing in the pachinko gaming machine 100 according to the subsequent authentication result data received from the subsequent unit 202B. The processing unit 353 extracts a control command from the control signal received from the main control board 310 and performs a predetermined process corresponding to the control command when the latter-stage authentication result data indicates that authentication is established. Moreover, the process part 353 alert | reports, when the said back | latter authentication result data has shown authentication failure. Note that the predetermined processing is performed in accordance with a control command from the main control unit 201 in the pachinko gaming machine 100, for example, processing such as loss processing, jackpot reach processing, jackpot start processing, jackpot round processing, jackpot end processing, etc. Is mentioned.

  In the present embodiment, data that is communicated between the peripheral unit 202A and the subsequent unit 202B is not encrypted. However, data that is communicated between the peripheral unit 202A and the subsequent unit 202B is also encrypted. It can also be configured.

The subsequent authentication program 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.

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

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

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

(Details of processing by each control unit)
Next, details of various processes performed by each control unit will be described. First, 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 the authentication information is generated, so that the processing load on the main control board 310 can be reduced. Further, each time the control unit 202 receives a control command, the post-stage unit 202 </ b> B of the peripheral board 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, a process for a jackpot reach command (when a jackpot reach command (see step S413 in FIG. 5) or a loss reach command (see step S419 in FIG. 5) is received) and a jackpot reach process will be described.

  First, the symbol variation process by the effect control unit 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, if it is determined that the symbol control command 202A has been received (S701: Yes), in step S702, the random effect selection random number is acquired, and in step S703, the variable effect is selected based on the acquired random number. The type is selected, and the process proceeds to step S704. In step S704, the effect control unit 202A transmits an effect start command for each variable effect to the lamp control unit 251 and the sound control unit 252, and the process proceeds to step S705.

  In step S705, the effect control unit 202A determines whether or not 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. An example of the identification data is an authentication command that is different from the control command of the control command data 1001. For example, a value such as hexadecimal 0xA0 is set. As a result, the post-stage unit 202B can identify whether or not the authentication information 1020 is based on the identification unit 1021. The authentication command is differentiated as a command system different from the control command described above.

  The data unit 1022 is set with one piece of authentication data generated by the authentication data generation unit 314 described above. The data unit 1022 of the present embodiment will be described with respect to a case where only authentication data is set. Alternatively, the data unit 1022 may be configured to set authentication data and other data in the data unit 1022. it can. Examples of other data include data accompanying an authentication command such as the accompanying data 1002 described above.

(Example of authentication data generation method)
Next, an example of three or more types of generation methods corresponding to authentication data will be described below. In order to simplify the description, three types of generation methods will be described, but four or more types of generation methods may be used.

  As shown in FIG. 12, for the generation of authentication data, it is possible to apply three types of generation methods, a first generation method M1, a second generation method M2, and a third generation method M3, which are determined in advance. . The first generation method M1 is a generation method for generating authentication data using only the inspection value. The first generation method M1 indicates a generation method in which one of the two types of inspection values described above is used as authentication data as it is. For example, the main control board 310 extracts from the data storage unit 311 the inspection value corresponding to the next generation method determined by the determination unit 312 based on the first generation method, and the authentication data that is the extracted inspection value. (Authentication data = inspection value).

  The second generation method M2 is a generation method for generating authentication data by combining the inspection value and the other value. The second generation method M2 indicates a generation method that generates a combined value obtained by combining one of the above-described two types of inspection values and history data (other values) to obtain authentication data. For example, in the second generation method M2, a test value and a history are combined with a predetermined function f to generate a combined value to be authentication data (authentication data = f (inspection value, history)). When the function f indicates the addition of the inspection value and the history, authentication data = inspection value + history. In addition to addition, the function f may be various embodiments such as various operations such as subtraction, multiplication, and bit operation, and a combination of these operations. As the history data used as other values, the history data of the data storage unit 311 described above is used.

  The third generation method M3 is a generation method for generating authentication data using only dummy data different from the inspection value. The third generation method M3 is for authenticating a predetermined individual value, variable value, and the like as they are. The generation method used as data is shown. That is, as long as the dummy data is a value different from the inspection value, either a fixed value or a variable value may be used.

  Moreover, when it is set as four or more types of production | generation methods, it can implement | achieve by increasing the combination pattern of the test value of the 2nd production | generation method mentioned above, and another value. For example, when other values such as the number of transmissions of the control command and the number of predetermined processings can be used, the number of generation methods can be increased by the number of types of other values.

  Next, an example of a design method of three or more generation methods, inspection values, and expected values will be described. First, as shown in FIG. 13, when the above-described three types of first generation method M1 to third generation method M3 are determined in advance, inspection values A1 to A3 are associated with each generation method M on a one-to-one basis. Then, the expected values B1 to B3 that coincide with each of the inspection values A1 to A3 are associated with each other in a one-to-one relationship, so that the expected values B1 to B3 and the first generation method M1 to the third generation method M3 are also associated one to one. It is done.

  For example, when applying the authentication method of the present invention to the pachinko gaming machine 100, the designer or the like arbitrarily selects two types of generation methods M from among the three types of first generation method M1 to third generation method M3. When it is decided to use the first generation method M1 and the second generation method M2, the two inspection values A1 and A2 are stored in the data storage unit 311 of the main control board 310 when the pachinko gaming machine 100 is manufactured. The two expected values B1 and B2 are stored in the peripheral storage unit 332 of the peripheral substrate 330 in a one-to-one correspondence with the first generation method M1 and the second generation method M2 (first and second storage steps). Then, each program for performing processing corresponding to the first generation method M1 and the second generation method M2 is stored in each of the main control board 310 and the peripheral board 330.

  In the present embodiment, the case where the first generation method M1 and the second generation method M2 are selected from the three generation methods M will be described, but instead, the first generation method M1 and the third generation method M2 are used. When M3 is selected, when the second generation method M2 and the third generation method M3 are selected, the inspection values, expected values, and programs associated with the respective cases shown in FIG. And stored in the peripheral substrate 330.

  Further, in this embodiment, a case where two types of generation methods M are selected for the pachinko gaming machine 100 will be described, but instead of this, for example, two types of generation methods are provided for each pachinko gaming machine 100. Various embodiments such as selecting M and selecting two types of generation methods M for each gaming machine manufacturer can be adopted. If a combination of a plurality of types of generation methods M is set for each of the pachinko gaming machines 100, there are a plurality of combinations of a plurality of types of generation methods M in the same series of pachinko gaming machines 100. Analysis can be made even more difficult.

(Processing for sending and receiving authentication information signals)
Below, the example of communication of the said authentication information signal performed between the main-control part 201 and a peripheral part is demonstrated. First, an example of an authentication information signal transmission procedure by the CPU 211 (first computer) of the main control unit 201 will be described with reference to the flowchart of FIG. The description will be made on the assumption that the above-described first generation method M1 and second generation method M2 are used.

  When the power of the pachinko gaming machine 100 is turned on (turned on), the main control unit 201 executes an authenticated process shown in FIG. 14 and determines whether or not it is a predetermined authentication timing in step S1201. If the main control unit 201 determines that it is not the authentication timing (S1201: No), the process proceeds to step S1209. 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 next generation method M set in the generation method information of the data storage unit 311 as the current generation method, and then proceeds to the processing of step S1203. When the next generation method M is not set in the generation method information, that is, in the first process, the initial generation method M predetermined as an initial value in the pachinko gaming machine 100 is set as the current generation method M. In the following description, it is assumed that the first generation method M is the first generation method M1.

  In step S1203, the main control unit 201 randomly selects the next setting method M to be used for generating authentication data in the next processing from the two predetermined first generation methods M1 and M2. The determined next generation method M is set in the generation method information of the data storage unit 311, and then the process proceeds to step S 1204. An example of a method for determining the next generation method M includes a method of determining using a random number or a pattern table.

  In step S1204, the main control unit 201 extracts the inspection value corresponding to the determined next generation method M from the two types of inspection values A1 and A2 stored in the data storage unit 311 and the RAM 213 or the like. Then, the process proceeds to step S1205.

  In step S1205, the main control unit 201 determines the current generation method, that is, the next time determined in the previous process, based on at least one of the inspection value associated with the determined next generation method M and the other value. Is generated and stored in the RAM 213 or the like, and then the process proceeds to step S1206. If the next generation method M1, the authentication data that is the inspection value is generated, and if the next generation method M2 is the next time, the combined value obtained by combining the inspection value and the history data (other values). That is, the authentication data is generated.

  In step S1206, the main control unit 201 sets a predetermined authentication command in the identification unit 1021 of the authentication information 1020, sets the generated authentication data in the data unit 1022, and generates authentication information 1020. The generated authentication information 1020 is stored in the data storage unit 311 or the like, and then the process proceeds to step S1207.

  In step S1207, the main control unit 201 encrypts the generated authentication information 1020 with a predetermined encryption method with the subsequent stage unit 202B, and in step S1208, each of the encrypted authentication information 1020 is encrypted. The authentication information signal is generated based on this and transmitted from the main control side transmission unit 316 to the peripheral unit 202A, so that the authentication information signal is transmitted to the subsequent stage unit 202B via the peripheral unit 202A, and then in step S1208 Proceed to processing. If encryption is not required between the main control unit 201 and the peripheral unit 202A and the post-stage unit 202B, the processing in step S1207 is deleted and the authentication information 1020 is transmitted to the peripheral unit 202A as it is.

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

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

  When executing the authentication side processing shown in FIG. 15, 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 stage 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 post-stage unit 202B initializes the determination result information and the like in the post-stage storage unit 332, and decrypts the received authentication information 1020 with a decryption method corresponding to the encryption method of the main control unit 201. The authentication data is extracted from the data portion 1022 of the authentication information 1020 and stored in the subsequent storage unit 332 or the like, 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 step S1305, the latter stage unit 202B compares the extracted authentication data with the two types of expected values of the rear side storage unit 332, and determines whether the authentication data matches one of the two types of expected values. Determine whether. If it is determined that the authentication data does not match the expected value (S1305: No), the latter stage unit 202B can determine that the authentication data is not generated by the first generation method M1, and the process of step S1307 is performed. move on. On the other hand, if the latter stage unit 202B determines that the authentication data matches the expected value (S1305: Yes), it can be determined as the authentication data generated by the first generation method M1, so in step S1306, The first generation method M1 is set in the determination result information of the subsequent-stage storage unit 332, and then the process proceeds to step S1307.

  In step S1307, the rear stage unit 202B corresponds to the second generation method M2 with each of the two types of expected values stored in the rear stage storage unit 332 and the history data stored in the rear stage storage unit 332. The synthesized value is synthesized by the synthesis method and stored in the RAM 23 or the like, and then the process proceeds to step S1308.

  In step S1308, the subsequent stage unit 202B compares the extracted authentication data with the combined value and determines whether the authentication data and the combined value match. If it is determined that the authentication data and the composite value do not match (S1308: No), the latter stage unit 202B can determine that the authentication data is not the authentication data generated by the second generation method M2, and the rear stage storage unit 332 Nothing is set in the determination result information, and the process proceeds to step S1310. On the other hand, when the latter stage unit 202B determines that the authentication data and the composite value match (S1308: Yes), it can be determined as the authentication data generated by the second generation method M2, and therefore in step S1309, The second generation method M2 is set in the determination result information of the downstream side storage unit 332, and then the process proceeds to step S1310.

  In step S1310, the subsequent stage unit 202B compares the determination result information in the subsequent stage storage unit 332 with the subsequent generation method information, and determines whether or not the authentication data generation method M matches the current setting method M. Determine. If it is determined that the post-stage unit 202B matches the current generation method (S1310: Yes), in step S1311, post-stage authentication result data indicating the establishment of authentication is generated and stored in the RAM 23 or the like, and then in step S1312. Proceed to processing. In step S1312, the subsequent stage unit 202B specifies the generation method M associated with the expected value that matches the authentication data in step S1305, and stores the specified generation method M as the next generation method M in the subsequent stage storage. Set to the subsequent generation method information of the unit 332, and then the process proceeds to step S1314. When the authentication data does not have an inspection value, the predetermined generation method M is set as the next generation method M.

  On the other hand, if the post-stage unit 202B determines in step S1310 that it does not match the current generation method (S1310: No), in step S1313, authentication for the main control unit 201 is not established, and the post-stage authentication result indicating that 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 335 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, when it is determined that the power source is turned off (S1315: Yes), the peripheral unit ends the process according to this flowchart.

  In the flowchart shown in FIG. 15, a case has been described in which a series of processing in steps S1307 to S1309 is executed even if it is determined in step S1305 that the authentication data matches the expected value (S1305: Yes). However, instead of this, in the case where they match, it is also possible to adopt an embodiment in which the process proceeds from step S1303 to step S1310.

  Next, a procedure for receiving various control signals, an authentication information signal, and a post-authentication result signal by the CPU 241 (second computer) of the peripheral unit 202A will be described with reference to a 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 authentication information)
Next, an example of a procedure for performing authentication of the main control board 310 by switching between the first generation method M1 and the second generation method M2 shown in FIG. 12 will be described with reference to the drawing in FIG.

  In FIG. 17, the main control board 310, which is the person to be authenticated, sets a predetermined first generation method M1 for the current generation from the generation method information in the data storage unit 311 (S1501). The main control board 310 randomly determines the second generation method M2 as the next generation method M from the first generation method M1 and the second generation method M2, and sets it as the generation method information in the data storage unit 311. (S1502). As shown in FIG. 13, the main control board 310 extracts the inspection value A2 associated with the determined second generation method M2 from the data storage unit 311 and checks the inspection value based on the current first generation method M1. A2 authentication data is generated (S1503). In this case, since the first generation method M1 indicates that the inspection value A is used as it is for the authentication data, authentication data that is the inspection value A2 is generated. Then, the main control board 310 sets the authentication command in the identification part 1021 of the authentication information 1020 and sets the generated authentication data in the data part 1022 to generate the authentication information 1020 (S1504), and the authentication information 1020 is set to the peripheral board. The data is transmitted to the rear stage part 202B of 330 via the peripheral part 202A (S1505). Therefore, the main control board 310 switches from the first generation method M1 to the second generation method M2 in the next authentication process.

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

  On the other hand, when the rear stage section 202B of the peripheral board 330 receives the authentication information 1020 from the main control board 310 (S1521), the authentication data in the data section 1022 of the authentication information 310 and the two stored in the rear stage storage section 332 The main control board 310 is authenticated by determining whether or not the expected value matches, and post-stage authentication result information 1030 having post-stage authentication result data indicating the authentication result is generated and stored in the post-stage storage unit 332. (S1522). In this case, since the authentication data is the inspection value A2 and coincides with the inspection value B2, the generation method M can be determined to be the first generation method M1. The first generation method M1 matches the current generation method M indicated by the subsequent-stage generation method information of the subsequent-stage storage unit 332. Therefore, the post-stage unit 202B establishes the authentication of the main control board 310 because the inspection value A2 is a regular one and the generation method also matches.

  When the authentication is established, the rear stage unit 202B specifies the second generation method M2 associated with the expected value B2 that matches the authentication data, and sets the specified second generation method M2 as the next generation method M as the subsequent stage. This is set in the subsequent generation method information on the side storage unit 332 (S1523). The post-stage unit 202B transmits a post-stage authentication result signal to which the post-stage authentication result information 1030 is added to the peripheral part 202A of the peripheral board 330 (S1524). Therefore, the rear stage unit 202B switches from the first generation method M1 to the second generation method M2 in the next authentication process.

  On the other hand, the peripheral part 202A of the peripheral board 330 is configured such that the control command data 1001 and the accompanying data received from the main control part 201 are received when the latter authentication result information 1030 received from the latter part 202B indicates that authentication is 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 second generation method M2 indicated by the generation method information in the data storage unit 311 as the current generation method M (S1531). The main control board 310 randomly determines the first generation method M1 as the next generation method M from the first generation method M1 and the second generation method M2, and sets it as the generation method information in the data storage unit 311. (S1532). As shown in FIG. 13, the main control board 310 extracts the inspection value A1 associated with the determined first generation method M1 from the data storage unit 311 and performs the inspection based on the current second generation method M2. Authentication data that is a combined value (= inspection value A1 + history data) obtained by combining the value A1 and the history data in the data storage unit 311 is generated (S1533). The main control board 310 sets the authentication command in the identification part 1021 of the authentication information 1020 and sets the generated authentication data in the data part 1022 to generate the authentication information 1020 (S1534). The authentication information 1020 is stored in the peripheral board 330. The data is transmitted to the rear stage section 202B via the peripheral section 202A (S1535). Therefore, the main control board 310 switches from the second generation method M2 to the first generation method M1 in the next authentication process.

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

  On the other hand, when the rear stage section 202B of the peripheral board 330 receives the authentication information 1020 from the main control board 310 (S1551), the authentication data in the data section 1022 of the authentication information 310 and the two data stored in the rear stage storage section 332 are stored. The main control board 310 is authenticated by determining whether or not the expected value matches, and post-stage authentication result information 1030 having post-stage authentication result data indicating the authentication result is generated and stored in the post-stage storage unit 332. (S1552). In this case, since the authentication data is a composite value and does not match the expected values B1 and B2, there is a possibility of the authentication data generated by the second generation method M2. Therefore, the latter stage unit 202B determines whether or not these expected values B1 and B2 and the latter stage history data match the synthesized value synthesized by the second generation method M2, and if they match, it is the second generation method M2. If they do not match, it is determined that the data is invalid. Therefore, the post-stage unit 202B establishes authentication of the main control board 310 if the authentication data and the composite value match and the generation method M also matches.

  When the authentication is established, the rear stage unit 202B specifies the first generation method M1 associated with the expected value B1 that constitutes the composite value that matches the authentication data, and sets the specified first generation method M1 next time. The generation method M is set in the subsequent-stage generation method information of the subsequent-stage storage unit 332 (S1553). The post-stage unit 202B transmits a post-stage authentication result signal added with the post-stage authentication result information 1030 to the peripheral part 202A of the peripheral board 330 (S1554). Therefore, the rear stage unit 202B switches from the second generation method M2 to the first generation method M1 in the next authentication process.

  On the other hand, the peripheral part 202A of the peripheral board 330 is configured such that the control command data 1001 and the accompanying data received from the main control part 201 are received when the latter authentication result information 1030 received from the latter part 202B indicates that authentication is 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). Thereafter, the same authentication process as described above is performed.

  According to the pachinko gaming machine 100 described above, two types of first and second generation methods M1 and M2 determined in advance from among three or more first generation methods M1 to M3 of authentication data. Two inspection values A1 and A2 are associated with each other, and the main control side generates the data for authentication of the current generation method M using at least one of the inspection value A corresponding to the next generation method M and other values, Since the authentication information 1020 having the authentication data is generated and transmitted to the rear stage part 202B of the peripheral board 330 via the peripheral part 202A, the rear stage part 202B has two inspection values A1, 1 of the main control board 310. Since the authentication data generation method M can be specified based on the two expected values B1 and B2 that coincide with A2, the authentication of the main control board 310 based on the authentication data generation method M and the inspection value A The In Ukoto, it is possible to prevent the illegal analysis who is illegally using the authentication information 1020. Further, when the authentication of the main control board 310 is established, the rear stage unit 202B specifies the next generation method M based on the inspection value A of the authentication data, so that an unauthorized analyst obtains the authentication information 1020. Since the subsequent stage 202B of the peripheral board 330 can detect that the authentication data has been used illegally by the fraud analyst, the subsequent stage 202B of the peripheral board 330 can detect the authentication information 1020. The authentication strength can be increased. In addition, since two types of generation methods M can be selectively used from among three or more types, a plurality of combination patterns of two types of generation methods can be used even in the same series of pachinko gaming machines 100. Since the combination pattern of two types of generation methods can be used instead for each time, the authentication information 1020 can be versatile. 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 the two inspection values can be stored in advance, it is not necessary to perform a complicated calculation when generating the authentication information 1020, and an increase in processing load on the main control unit 201 can be prevented. In addition, since the peripheral unit 202A transmits the control command from the main control unit 201 to the subsequent unit 202B as it is, the peripheral unit 202A can perform a predetermined process at the same time as the subsequent unit 202B performs an authentication process. Thus, it is possible to prevent a delay from occurring in the predetermined processing in the peripheral portion 202A. Therefore, it is possible to make the authentication information 1020 versatile by making it difficult to perform illegal analysis of the authentication information 1020.

  Further, in the pachinko gaming machine 100 described above, the three or more types of the first to third generation methods M1 to M3 are the generation methods M corresponding to each of the inspection value A, the composite value, and the dummy data. Analysis of authentication data by a person can be made even more difficult. Further, since other types of data corresponding to the second generation method M2 can use a plurality of types of data, it is possible to increase the types of generation methods, and further analyze the authentication data and the generation method M. Can be difficult.

  In the pachinko gaming machine 100 described above, since the other value of the second generation method M2 is used as the history data of the control command, the history data is a value that changes according to the transmission of the control command. The authentication data generated by the generation method M2 becomes a variable value, which can make analysis by an unauthorized analyst more difficult. Further, since it is possible to determine whether or not the control command histories of both the main control board 310 and the rear stage 202B of the peripheral board 330 match, the rear stage 202B takes into account the validity of the control command. Authentication of the control board 310 can be performed.

  Furthermore, 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 times the authentication information 1020 is transmitted is reduced, 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 addition, in the pachinko gaming machine 100 described above, when the inspection value A cannot be extracted from the authentication data, the subsequent generation unit 202B identifies the predetermined generation method M as the next generation method M, so that the two generation methods On the other hand, since it is possible to generate only one data different from the inspection value A, it is possible to make it difficult for an unauthorized analyst to analyze the two types of inspection values A. Prevention and improvement in detection accuracy can be achieved.

[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. 18, 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 data generation unit 314, the authentication information generation unit 315, the main control side transmission unit 316, and the selection unit 313 described above. Yes.

  The selection unit 313 corresponds to selection means of the present invention, and randomly selects one inspection value A from the two types of inspection values A1 and A2 stored in the data storage unit 311. The selection unit 313 selects one inspection value using a random number or the like. In the selection method of the selection unit 313, the selection pattern is preferably irregular in order to prevent unauthorized analysis.

  The determination unit 312 described above uses the generation method M (see FIG. 13) associated with the inspection value A selected by the selection unit 313 as the next generation method M of authentication data used for the next authentication of the main control board 310. And the generation method information of the data storage unit 311 (generation method information storage means) is updated so as to indicate the next generation method M.

  The authentication data generation unit 314 described above is based on at least one of the inspection value A selected by the selection unit 313 and another value, the generation method previously determined by the determination unit 312, that is, the generation method indicated by the generation method information M authentication data is generated. When the third generation method M3 is the next generation method M, the authentication data generation unit 314 generates authentication data that does not have the selected inspection value A.

  In the pachinko gaming machine 100 according to the second embodiment, two types of generation methods are determined in advance at the time of design, manufacture, etc. from among three or more types of generation methods, and a program for performing processing corresponding to the two types of generation values and two inspection values The data is stored in advance in the data storage unit 311 of the main control board 310 at the time of manufacture. Then, the pachinko gaming machine 100 generates authentication data for one of the two generation methods using at least one of the inspection value and the other value, and generates authentication information having the authentication data. The main control board 310 transmits data to the rear stage part 202B of the peripheral board 330 via the peripheral part 202A, and the rear stage part 202B adopts a configuration in which the main control board 310 is authenticated based on the authentication data generation method. Yes. Therefore, the pachinko gaming machine 100 can make it difficult to illegally analyze the authentication data even if one kind of authentication information is used, so that security is improved and the authentication information is versatile. Can be made.

  Subsequently, the peripheral portion 202A of the peripheral substrate 330 illustrated in FIG. 18 includes the transfer unit 351, the peripheral-side receiving unit 352, and the processing unit 353 described above as in the first embodiment. The post-stage unit 202B also includes the above-described post-stage reception unit 331, post-stage storage unit 332, post-stage authentication result data generation unit 333, post-stage transmission unit 334, and identification unit 335, as in the first embodiment. doing. 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 for causing the first computer to function as various means such as selection means, authentication data generation means, authentication information generation means, transmission means, and determination means in the claims. Side authentication program is stored. 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. In addition, the ROM 22 in the rear stage 202B of the peripheral board 330 causes the third computer to function as various means such as a rear side receiving means, a rear stage authentication result data generating means, a rear stage side transmitting means, and a specifying means in the claims. The subsequent authentication program 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. 19 and determines in step S1501 whether or not it is a predetermined authentication timing. If the main control unit 201 determines that it is not the authentication timing (S1501: No), the main control unit 201 proceeds to the process of step S1508. On the other hand, if the main control unit 201 determines that it is the authentication timing (S1501: Yes), the process proceeds to step S1502.

  In step S1502, the main control unit 201 sets the next generation method M set in the generation method information of the data storage unit 311 as the current generation method, and then proceeds to the processing of step S1503. When the next generation method M is not set in the generation method information, that is, in the first process, the initial generation method M predetermined as an initial value in the pachinko gaming machine 100 is set as the current generation method M. In the following description, it is assumed that the first generation method M is the first generation method M1.

  In step S1503, the main control unit 201 randomly selects one test value from the two test values A1 and A2 stored in the data storage unit 311 using a random number or the like, and stores it in the RAM 213 or the like. Thereafter, the process proceeds to step S1504.

  In step S1504, the main control unit 201 generates authentication data for the current generation method, that is, the next generation method determined in the previous process, based on at least one of the selected inspection value A and another value. Then, the data is stored in the RAM 213 or the like, and then the process proceeds to step S1505. If the next generation method M1, the authentication data that is the inspection value is generated, and if the next generation method M2 is the next time, the combined value obtained by combining the inspection value and the history data (other values). That is, the authentication data is generated.

  In step S1505, the main control unit 201 sets a predetermined authentication command in the identification unit 1021 of the authentication information 1020, sets the generated authentication data in the data unit 1022, and generates authentication information 1020. The generated authentication information 1020 is stored in the data storage unit 311 or the like, and then the process proceeds to step S1506.

  In step S1506, the main control unit 201 encrypts the generated authentication information 1020 with a predetermined encryption method with the peripheral unit, and in step S1507, based on each of the encrypted authentication information 1020. Then, an authentication information signal is generated 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 S1508. If encryption is not required between the main control unit 201 and the peripheral unit 202A and the subsequent unit 202B, the processing in step S1507 is deleted and the authentication information 1020 is transmitted to the subsequent unit 202B as it is.

  In step S1508, the main control unit 201 determines the generation method M corresponding to the selected inspection value A as the next generation method M and stores the determined next generation method M in the data storage as shown in FIG. Is set in the generation method information of the unit 311, and then the process proceeds to step S <b> 1509.

  In step S1509, 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 (S1509: No), the process returns to step S1501 and repeats a series of processes. On the other hand, when the main control unit 201 determines that the power is turned off (S1509: 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. 16 of the first embodiment and the authentication side process shown in FIG.

(Example 2 of authentication processing procedure using authentication information)
Next, an example of a procedure for performing authentication of the main control board 310 by switching between the first generation method M1 and the second generation method M2 shown in FIG. 12 will be described with reference to the drawing of FIG.

  In FIG. 19, the main control board 310, which is the person to be authenticated, sets a predetermined first generation method M1 from the generation method information in the data storage unit 311 (S1701). When the main control board 310 randomly selects one inspection value A2 from the two inspection values A1 and A2 (S1702), the main control board 310 is used for authentication of the selected inspection value A2 based on the current first generation method M1. Data is generated (S1703). The main control board 310 sets the authentication command in the identification section 1021 of the authentication information 1020 and the generated authentication data in the data section 1022 to generate the authentication information 1020 (S1704). The authentication information 1020 is stored in the peripheral board 330. The data is transmitted to the rear stage section 202B via the peripheral section 202A (S1705). Then, as shown in FIG. 13, the main control board 310 determines the second generation method M2 associated with the selected inspection value A2 as the next generation method M, and generates the generation method information in the data storage unit 311. The setting is made (S1706). Therefore, the main control board 310 switches from the first generation method M1 to the second generation method M2 in the next authentication process.

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

  On the other hand, when the rear stage section 202B of the peripheral board 330 receives the authentication information 1020 from the main control board 310 (S1721), the authentication data in the data section 1022 of the authentication information 310 and the two stored in the rear stage storage section 332 The main control board 310 is authenticated by determining whether or not the expected value matches, and post-stage authentication result information 1030 having post-stage authentication result data indicating the authentication result is generated and stored in the post-stage storage unit 332. (S1722). In this case, since the authentication data is the inspection value A2 and coincides with the inspection value B2, the generation method M can be determined to be the first generation method M1. The first generation method M1 matches the current generation method M indicated by the subsequent-stage generation method information of the subsequent-stage storage unit 332. Therefore, the post-stage unit 202B establishes the authentication of the main control board 310 because the inspection value A2 is a regular one and the generation method also matches.

  When the authentication is established, the rear stage unit 202B specifies the second generation method M2 associated with the expected value B2 that matches the authentication data, and sets the specified second generation method M2 as the next generation method M as the subsequent stage. This is set in the subsequent generation method information of the side storage unit 332 (S1723). The post-stage unit 202B transmits a post-stage authentication result signal added with the post-stage authentication result information 1030 to the peripheral part 202A of the peripheral board 330 (S1724). Therefore, the rear stage unit 202B switches from the first generation method M1 to the second generation method M2 in the next authentication process.

  On the other hand, the peripheral part 202A of the peripheral board 330 is configured such that the control command data 1001 and the accompanying data received from the main control part 201 are received when the latter authentication result information 1030 received from the latter part 202B indicates that authentication is 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 second generation method M2 determined in advance from the generation method information in the data storage unit 311 (S1721). When the main control board 310 randomly selects one inspection value A2 from the two inspection values A1 and A2 (S1722), based on the second generation method M2 of this time, the inspection value A2 and the data storage unit 311 are selected. The authentication data is generated as a combined value (= inspection value A2 + history data) obtained by combining the history data (S1723). The main control board 310 sets the authentication command in the identification section 1021 of the authentication information 1020 and the generated authentication data in the data section 1022 to generate the authentication information 1020 (S 1724). The authentication information 1020 is stored in the peripheral board 330. The data is transmitted to the rear stage section 202B via the peripheral section 202A (S1725). Then, as shown in FIG. 13, the main control board 310 determines the second generation method M2 associated with the selected inspection value A2 as the next generation method M, and generates the generation method information in the data storage unit 311. Set (S1726). Therefore, the main control board 310 continues to use the second generation method M2 in the next authentication process.

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

  On the other hand, when the rear stage part 202B of the peripheral board 330 receives the authentication information 1020 from the main control board 310 (S1751), the authentication data in the data part 1022 of the authentication information 310 and the two data stored in the rear side storage part 332 are stored. The main control board 310 is authenticated by determining whether or not the expected value matches, and post-stage authentication result information 1030 having post-stage authentication result data indicating the authentication result is generated and stored in the post-stage storage unit 332. (S1752). In this case, since the authentication data is a composite value and does not match the expected values B1 and B2, there is a possibility of the authentication data generated by the second generation method M2. Therefore, the latter stage unit 202B determines whether or not these expected values B1 and B2 and the latter stage history data match the synthesized value synthesized by the second generation method M2, and if they match, it is the second generation method M2. If they do not match, it is determined that the data is invalid. Therefore, the post-stage unit 202B establishes authentication of the main control board 310 if the authentication data and the composite value match and the generation method M also matches.

  When the authentication is established, the rear stage unit 202B specifies the second generation method M2 associated with the expected value B2 that constitutes the composite value that matches the authentication data, and sets the specified second generation method M2 for the next time The generation method M is set in the subsequent-stage generation method information of the subsequent-stage storage unit 332 (S1753). The post-stage unit 202B transmits a post-stage authentication result signal to which the post-stage authentication result information 1030 is added to the peripheral unit 202B of the peripheral board 330 (S1754). Therefore, the subsequent stage unit 202B continues to use the second generation method M2 in the next authentication process.

  On the other hand, the peripheral part 202A of the peripheral board 330 is configured such that the control command data 1001 and the accompanying data received from the main control part 201 are received when the latter authentication result information 1030 received from the latter part 202B indicates that authentication is 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). Thereafter, the same authentication process as described above is performed.

  According to the pachinko gaming machine 100 described above, as in the first embodiment, two types of first and first predetermined ones of three or more first generation methods M1 to M3 of authentication data are determined. The two generation values M1 and M2 are associated with the two inspection values A1 and A2, and the main control side uses the inspection value A corresponding to the next generation method M and at least one of the other values. Since the authentication data is generated, the authentication information 1020 having the authentication data is generated and transmitted to the rear stage 202B of the peripheral board 330 via the peripheral part 202A, the rear stage 202B is connected to the main control board 310. Since the authentication data generation method M can be specified based on the two expected values B1 and B2 that match the two inspection values A1 and A2, the authentication data generation method M and the inspection value A are used. Main control By performing authentication of the plate 310, it is possible to prevent the illegal analyst illegally using the authentication information 1020. Further, when the authentication of the main control board 310 is established, the rear stage unit 202B specifies the next generation method M based on the inspection value A of the authentication data, so that an unauthorized analyst obtains the authentication information 1020. Since the subsequent stage 202B of the peripheral board 330 can detect that the authentication data has been used illegally by the fraud analyst, the subsequent stage 202B of the peripheral board 330 can detect the authentication information 1020. The authentication strength can be increased. In addition, since two types of generation methods M can be selectively used from among three or more types, a plurality of combination patterns of two types of generation methods can be used even in the same series of pachinko gaming machines 100. Since the combination pattern of two types of generation methods can be used instead for each time, the authentication information 1020 can be versatile. 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 the two inspection values can be stored in advance, it is not necessary to perform a complicated calculation when generating the authentication information 1020, and an increase in processing load on the main control unit 201 can be prevented. In addition, since the peripheral unit 202A transmits the control command from the main control unit 201 to the subsequent unit 202B as it is, the peripheral unit 202A can perform a predetermined process at the same time as the subsequent unit 202B performs an authentication process. Thus, it is possible to prevent a delay from occurring in the predetermined processing in the peripheral portion 202A. Therefore, it is possible to make the authentication information 1020 versatile by making it difficult to perform illegal analysis of the authentication information 1020.

  Further, in the pachinko gaming machine 100 described above, the three or more types of the first to third generation methods M1 to M3 are the generation methods M corresponding to each of the inspection value A, the composite value, and the dummy data. Analysis of authentication data by a person can be made even more difficult. Further, since other types of data corresponding to the second generation method M2 can use a plurality of types of data, it is possible to increase the types of generation methods, and further analyze the authentication data and the generation method M. Can be difficult.

  In the pachinko gaming machine 100 described above, since the other value of the second generation method M2 is used as the history data of the control command, the history data is a value that changes according to the transmission of the control command. The authentication data generated by the generation method M2 becomes a variable value, which can make analysis by an unauthorized analyst more difficult. Further, since it is possible to determine whether or not the control command histories of both the main control board 310 and the rear stage 202B of the peripheral board 330 match, the rear stage 202B takes into account the validity of the control command. Authentication of the control board 310 can be performed.

  Furthermore, 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 times the authentication information 1020 is transmitted is reduced, 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 addition, in the pachinko gaming machine 100 described above, when the inspection value A cannot be extracted from the authentication data, the subsequent generation unit 202B identifies the predetermined generation method M as the next generation method M, so that the two generation methods On the other hand, since it is possible to generate only one data different from the inspection value A, it is possible to make it difficult for an unauthorized analyst to analyze the two types of inspection values A. Prevention and improvement in detection accuracy can be achieved.

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

  As described above, the present invention is useful for a gaming machine in which fraud to the main control unit is concerned and a control board mounted on the gaming machine, and in particular, a pachinko gaming machine, a slot gaming machine, and a sparrow ball gaming machine. It can be applied to various other gaming machines. Even in these gaming machines, the same effects as those of the above-described embodiments can be obtained by configuring similarly to the above-described embodiments.
