Description

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

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

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

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

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

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

When receiving the authentication information from the main control unit, the peripheral unit determines whether the authentication data of the authentication information matches the expected value or the peripheral side history data, and the authentication of the main control unit is performed based on the determination result. I do. Then, if the authentication data matches the expected value, the peripheral unit can similarly switch the history generation method of the peripheral side history data generation means by the same switching method as that of the main control unit.

  According to the gaming machine authentication method of the present invention described in claim 7, when the main control unit transmits a control command to the peripheral unit according to the operation of the gaming machine, the history data indicating the history is generated as a history generation method. Generate with The main control unit generates authentication information having the history data as authentication data and transmits it to the peripheral unit. Further, when the main control unit randomly determines to switch the history generation method, the main control unit generates authentication information having the individual identification value stored in the individual identification value storage unit as authentication data, and transmits it to the peripheral unit. The history generation method of the history data generation means can be switched by a predetermined switching method from a plurality of predetermined history generation methods. On the other hand, when the peripheral unit receives a control command from the main control unit, the peripheral unit performs predetermined processing corresponding to the control command, and transmits peripheral side history data indicating the history of the control command received from the main control unit to the main control unit. It is generated by the same history generation method. When receiving the authentication information from the main control unit, the peripheral unit determines whether the authentication data of the authentication information matches the expected value or the peripheral side history data, and the authentication of the main control unit is performed based on the determination result. I do. Then, if the authentication data matches the expected value, the peripheral unit can similarly switch the history generation method of the peripheral side history data generation means by the same switching method as that of the main control unit.

  As described above, according to the present invention, the main control unit transmits the authentication information having either one of the history data indicating the history of the control command or the individual identification value to the peripheral part, and the authentication information having the individual identification value is transmitted. Since the history generation method for generating history data in response to transmission is switched, history data can be generated by switching the history generation method, making it difficult to analyze the history data generation method. In addition, it can be difficult to estimate whether the authentication information has history data or an individual identification value. In addition, since the peripheral section only has to switch the history generation method of the peripheral side history data in the same way as the main control section in response to the reception of the authentication information having the individual identification value, it is easy to synchronize with the main control section, and the authentication information is illegal. When this occurs, the history generation methods do not match, which can contribute to prevention of fraud. And since the peripheral unit has confirmed and authenticated the communication continuity of the control command based on the history data, it can detect unauthorized communication switching by an unauthorized control command. It can contribute to prevention. Since the history generation method is switched, the continuity of the history data to be generated is lost, and unauthorized analysis of the history data used for authentication information can be made difficult. Unauthorized use can be prevented. Specifically, fraud analysis based on the relationship (corresponding relationship) between the appearance order of control commands and the appearance order of history data can be made difficult. Furthermore, since the individual identification value can be stored in advance, it is not necessary to perform a complicated calculation when generating authentication information, and an increase in processing load on the main control unit can be prevented. Therefore, the communication continuity of the control command can be confirmed and the analysis of authentication information used for authentication can be made difficult.

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

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

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

When the prize ball control unit 203 detects a game operation by the sensor of the launch unit 292, the game ball 103 is intermittently fired by driving a solenoid or the like in response to the detected game operation, and the game area 103 of the game board 101 is played. A game ball is sent out.

  The main control unit 201, the effect control unit 202, and the prize ball control unit 203 configured as described above are provided on different printed circuit boards (main control board, effect board, and prize ball board). The configuration of the board of the pachinko gaming machine 100 is not limited to this. For example, the prize ball control unit 203 has various different configurations such as being provided on the same printed circuit board as the main control unit 201 or the effect control unit 202. be able to.

(Functional configuration of main control board and peripheral board)
First, a functional configuration of the main control board 310 having a function as the main control unit 201 will be described with reference to FIG. The main control board 310 is a functional unit that transmits a control command for operating the peripheral board 330, and includes a data storage unit 311, a history data generation unit 312, a selection unit 313, an authentication information generation unit 314, a switching unit 315, and transmission. Part 316. The main control board 310 is formed of a board different from the peripheral board 330 and is electrically connected so as to communicate with the peripheral board 330.

  The data storage unit 311 corresponds to the individual identification value storage means of the present invention, such as transmitted control command data (control command), authentication information, individual identification value, history generation method data (history generation method), switching information, etc. Various data are stored. As the data storage unit 311, for example, a part of the ROM 212 and the RAM 213 (see FIG. 2) of the main control unit 201 can be used. The data storage unit 311 has a storage area for storing a plurality of control commands and a plurality of authentication information transmitted to the peripheral unit in a time series as log data. The number of control commands and authentication information stored in the data storage unit 311 can be arbitrarily set. Further, the timing of storing the control command and authentication information in the data storage unit 311 can be arbitrarily determined at the time when it is determined, after being transmitted to the peripheral unit, and the like.

  The data storage unit 311 stores one or a plurality of individual identification values. The individual identification value is a value used by the peripheral board 330 for authentication (individual value identification) of the main control board 310 (main control unit). When a plurality of individual identification values are used, different data are used. As an example of the individual identification value, there are a checksum of a plurality of types of predetermined areas in the ROM 212 of the main control unit 210, a predetermined unique value, and the like. The history generation method data indicates the history generation method used by the history data generation unit 312, and an initial value is set at the time of startup or the like, and thereafter, the switching unit 315 performs switching.

  The history data generation unit 312 corresponds to a history data generation unit of the present invention, and history data indicating a history of control commands transmitted from the main control board 310 to the peripheral board (peripheral part) 330 is set in a predetermined history generation method. Generate with The history data generation unit 312 is a history generation method at a predetermined generation timing such as an arbitrary timing from the generation (determination) of a control command to the peripheral part of the control command in the pachinko gaming machine 100, for example. History data is generated and stored based on the control command data stored in the data storage unit 311. Then, the history data generation unit 312 calculates control command data for a predetermined number of transmissions based on a history generation method such as an error detection method, a predetermined encryption method, an exclusive OR, etc. Is generated. That is, in the history generation method, when generating history data for a control command, for example, the number of retroactive transmission of a single control command, the retroactive range of a plurality of types of control commands, etc. Stipulate. When the history data generation unit 312 generates the history data as a checksum, the history data is a total value obtained by taking a total value of a plurality of single types of control command data or a total of a plurality of control command data. Note that the history data can use the control command for one time such as the previous time or a predetermined number of times as it is, thereby simplifying the process when generating authentication information, which will be described later.

  The history data generation unit 312 according to the present embodiment will be described with respect to a case where the history data stored in the data storage unit 311 is updated and stored in the generated history data. In this case, the data storage unit 311 functions as history data storage means. Instead of this, for example, the history data may be stored in a register of the CPU 211, a predetermined storage area of the RAM 213, or the like. Also, the history data generating means and the storage means can be realized by dedicated hardware. If the history data generation unit 312 generates the same history data as the individual identification value, for example, the authentication information generation unit 314 does not generate authentication information having the history data, or the transmission unit 316 The authentication information including the history data is discarded without being transmitted. Alternatively, various embodiments may be adopted in which the history data generation unit 312 is designed so as to generate history data having a value different from the individual identification value, or corresponds to bit adjustment of history data.

  The selection unit 313 corresponds to the selection unit of the present invention, and the individual identification value stored in the data storage unit (individual identification value storage unit) 311 and the history data generated by the history data generation unit (history data generation unit) 312. Either of these is selected at random. The selection unit 313 uses a random number or the like so that the selection frequency between the individual identification value and the history data becomes random. The selection unit 313 can adjust the selection frequency by setting a random number or the like. For example, by setting a random number or the like so that only one out of ten selections becomes an individual identification value and increasing the selection frequency of history data, the continuity of communication of control commands is intensively monitored. Therefore, detection of unauthorized communication switching can be expected. In the present invention, since the history generation method is switched according to the occurrence of the individual identification value, the frequency of switching the history generation method can be increased by setting the selection frequency of the individual identification value high. It is possible to increase the difficulty of a simple analyst analyzing the switching timing.

  The authentication information generation unit 314 corresponds to the authentication information generation unit of the present invention. The authentication information used by the peripheral unit for authentication of the main control unit is either the individual identification value selected by the selection unit (selection unit) 313 or the history data. Either one is generated as authentication data. That is, when history data is selected by the selection unit 313, the authentication information generation unit 314 generates authentication information in which history data is set in the authentication data of the authentication information. Further, when the individual identification value is selected by the selection unit 313, the authentication information generation unit 314 generates authentication information in which the individual identification value is set in the authentication data of the authentication information. Therefore, the authentication information has authentication data, and either one of history data or individual identification value is set in the authorization data.

  The switching unit 315 corresponds to the switching unit of the present invention. When the selection unit (selection unit) 313 selects an individual identification value, the history generation method of the history data generation unit (history data generation unit) 312 is determined in advance. The plurality of history generation methods are switched by a predetermined switching method, and the history generation method data in the data storage unit 311 is set. For example, the switching unit 315 can switch between two types of history generation methods, or switch a plurality of history generation methods in order.

  The transmission unit 316 corresponds to a transmission unit of the present invention, and each of authentication information generated by the authentication information generation unit 314 and a plurality of control commands for controlling the peripheral substrate 330 is transmitted to the peripheral substrate (peripheral unit) 330. Send. Then, the transmission unit 316 of this embodiment transmits control command data from the main control board 310 to the peripheral board 330 as a control signal. For example, the transmission unit 316 transmits the authentication information to the peripheral board 330 as an authentication information signal that is a signal different from the control signal transmitted from the main control board 310 to the peripheral board 330. Thereby, in pachinko gaming machine 100, the control signal and the authentication information signal are differentiated.

  Next, a functional configuration of the peripheral board 330 having functions as peripheral parts such as the effect control unit 202 and the prize ball control unit 203 described above will be described. As shown in FIG. 3, the peripheral board 330 includes a receiving unit 331, a peripheral side storage unit 332, a peripheral side history data generation unit 333, an authentication unit 334, and a peripheral side switching unit 335.

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

  The peripheral side storage unit 332 corresponds to expected value storage means of the present invention. As the peripheral storage unit 332, for example, a part of the ROM 242 and the RAM 243 (see FIG. 2) of the effect control unit 202 can be used. The peripheral storage unit 332 also has a storage area for storing a plurality of control commands and a plurality of authentication information received from the main control board 310 as log data in a time series manner, like the main control board 310. Yes.

  The peripheral-side storage unit 332 displays one or more individual identification values to be received from the main control board 310 described above, that is, an expected value that matches the individual identification value stored in the data storage unit 311 of the main control board 310. I remember it. As a result, the peripheral board 330 can determine that the authentication data is a regular individual identification value if the authentication data set in the authentication information matches the expected value. Further, if the authentication data set in the authentication information does not match the expected value, it can be determined that it is not an individual identification value. The peripheral side storage unit 332 stores history generation method data similar to that of the main control unit 201. The history generation method data indicates a history generation method used by the peripheral side history data generation unit 333. An initial value is set at the time of startup or the like, and thereafter, the peripheral side switching unit 335 switches the data.

  The peripheral side history data generation unit 333 corresponds to the peripheral side history data generation means of the present invention, and the peripheral side history data indicating the history of the control command received from the main control board 310 is the same as the history generation of the main control board 310. Generate by method. The peripheral history data generation unit 333 receives the same history generation method and peripheral memory as the main control board 310 at a predetermined peripheral generation timing such as when a control command is received from the main control board 310, after receiving the control command. Based on the control command data stored in the unit 332, peripheral history data is generated and stored. That is, the peripheral history data generation unit 333 calculates control command data for a predetermined number of receptions based on a history generation method such as an error detection method, a predetermined encryption method, an exclusive OR, etc. Generate data. Therefore, if the peripheral side history data receives only the control command data transmitted by the main control board 310, it will match the history data of the main control board 310. It can be determined that data is being received.

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

  The authentication unit 334 corresponds to an authentication unit of the present invention, and based on a determination result whether or not authentication data of the received authentication information matches the expected value or the peripheral history data, a main control board ( The main control unit 310 is authenticated. If the authentication data matches the peripheral history data, the authentication unit 334 can determine that the authentication data has history data set and the control command used to generate the peripheral history data is valid. Establish authentication. If the authentication data matches the expected value, the authentication unit 334 establishes authentication because an individual identification value is set in the authentication data and it can be determined that a valid individual identification value has been received. That is, the authentication unit 334 establishes authentication of the main control board 310 when either the continuity of the communication state or the received individual identification value is valid. Note that the authentication unit 334 may be an embodiment in which authentication is established when it is determined that both the continuity of the communication state and the received individual identification value are valid.

  The peripheral side switching unit 335 corresponds to the peripheral side switching unit of the present invention, and when the authentication data of the received authentication information matches the expected value, the history generation method of the peripheral side history data generation unit 333 is changed to the main control. Similarly to the switching unit 315 of the substrate 310, switching is performed by a predetermined switching method from a plurality of predetermined history generation methods. Therefore, since the switching unit 315 and the peripheral side switching unit 335 can switch the history generation method with the synchronized switching timing and the same switching method, different history generation methods unless the peripheral board 330 receives unauthorized authentication information. It will not be switched to.

  The peripheral board 330 configured as described above performs a predetermined process in the pachinko gaming machine 100 in accordance with each of a plurality of types of control commands received from the main control board 310. The peripheral board 330 performs the predetermined processing corresponding to the control command indicated by the received control signal when the authentication unit 334 is authenticated, and notifies when the authentication is not established. The predetermined process is a process corresponding to each of a plurality of types of control commands from the main control unit 201 in the pachinko gaming machine 100. For example, an outage process, a jackpot reach process, a jackpot start process, a jackpot round process, Examples include jackpot end processing.

  The pachinko gaming machine 100 of the present invention transmits authentication information in which either history data or individual identification value is set from the main control board 310 to the peripheral board 330, and the peripheral board 330 is based on the history data of the authentication information. In this configuration, authentication is performed based on the continuity of communication of control commands, and authentication is performed based on the individual identification of the main control board 310 based on the individual identification value of the authentication information. The main control board 310 and the peripheral board 330 change the history data of the authentication information irregularly because the history generation method is switched by the same switching method according to the appearance of the authentication information having the individual identification value. Therefore, unauthorized analysis of authentication information can be made difficult. Therefore, even if the authentication information is transmitted alone from the main control unit 201 to the peripheral board 330, it can be difficult to easily analyze it.

  In the present embodiment, a case will be described in which the CPU 211 of the main control board 310 functions as the first computer in the claims and each of the CPUs 241 and 281 of the peripheral board 330 functions as the second computer in the claims. The ROM 212 of the main control board 310 is a main control side for causing the first computer to function as various means such as history data generation means, selection means, authentication information generation means, switching means, and transmission means in the claims. Remembers the authentication program. Each of the ROMs 242 and 282 of the peripheral board 330 is a peripheral for causing the second computer to function as various means such as receiving means, peripheral history data generating means, authentication means, and peripheral switching means in the claims. Side authentication program is stored. That is, the authentication program of the present invention is constituted by the main control side authentication program and the peripheral side authentication program.

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

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

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

(Details of processing by each control unit)
Next, details of various processes performed by each control unit will be described. First, control processing of the effect control unit 202 by the main control unit 201 will be described. 4 to 9, the authentication data and the accompanying data are not considered in order to clarify the control processing procedure of the effect control unit 202. That is, in the description of FIGS. 4 to 9, “send a command” means “send a control signal including data (control command data) indicating the command”. The presence or absence of data is not considered.

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

  In step S402, the main control unit 201 transmits a power-on command to each peripheral unit such as the effect control unit 202 and the prize ball control unit 203, and the process proceeds to step S403. When the power-on command is transmitted by this process, the effect control unit 202 controls the lamp control unit 251, the sound control unit 252, and the symbol display unit 104 for effect control at the time of power-on (specifically, Transmits a control command instructing lighting of a lamp, sound output, display of a demonstration (demo) screen, and the like.

  In step S <b> 403, the main control unit 201 refers to the unlottery winning number data stored in the ROM 212 or the RAM 213, and determines whether or not the unlotted winning number is zero. The number of undrawn winnings is the number obtained by subtracting the number of times that a lottery corresponding to the winning ball has been performed (number of already drawn lots) from the number of winning balls detected at the start winning opening 105 (number of winnings). If the main control unit 201 determines that the number of undrawn winning prizes is not zero (S403: No), the process proceeds to step S410. On the other hand, if the main control unit 201 determines that the number of undrawn winning prizes is zero (S403: Yes), in step S404, the main control unit 201 measures the time elapsed since the demonstration was started, and proceeds to the process of step S405. To do.

  The main control unit 201 determines whether or not a predetermined time has elapsed since the demonstration was started. If the main control unit 201 determines that the predetermined time has not elapsed since the demonstration was started (S405: No), the main control unit 201 proceeds to the process of step S407. On the other hand, if the main control unit 201 determines that a predetermined time has elapsed since the demonstration was started (S405: Yes), in step S406, the main control unit 201 transmits a customer waiting demonstration command to the effect control unit 202, and the process of step S407 Migrate to

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

  In step S412, the main control unit 201 determines whether or not the jackpot determination random number is a jackpot random number. If the main control unit 201 determines that it is a jackpot random number (S412: Yes), it transmits a jackpot reach command (symbol variation command) to the effect control unit 202 in step S413. In step S414, the main control unit 201 determines whether the symbol variation time has elapsed. When determining that the symbol variation time has not elapsed (S414: No), the main control unit 201 repeats this determination process to wait for the symbol variation time to elapse. On the other hand, if the main control unit 201 determines that the symbol variation time has elapsed (S414: Yes), in step S415, the main control unit 201 transmits a symbol stop command to the effect control unit 202, and the process proceeds to step S416.

  In step S416, the main control unit 201 transmits a jackpot start command to the effect control unit 202. Subsequently, in step S417, the main control unit 201 sequentially transmits commands corresponding to each of the rounds in the jackpot to the effect control unit 202. To do. When the transmission of the jackpot command for all rounds is completed, the main control unit 201 transmits the jackpot end command to the effect control unit 202 in step S418, and proceeds to the process of step S422.

  If the main control unit 201 determines in step S412 that the random number is not a big hit random number (S412: No), in step S419, the main control unit 201 transmits an outlier reach command (design variation command) to the effect control unit 202, and in step S420. Transition to processing. In step S420, the main control unit 201 determines whether the symbol variation time has elapsed. When determining that the symbol variation time has not elapsed (S420: No), the main control unit 201 repeats this determination process to wait for the symbol variation time to elapse. On the other hand, if the main control unit 201 determines that the symbol variation time has elapsed (S420: Yes), in step S421, the main control unit 201 transmits a symbol stop command to the effect control unit 202, and the process proceeds to step S422.

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

  The various commands in FIGS. 4 and 5 described above correspond to the control commands of the present invention, and the main control board 310 stores the control command data in the data storage unit 311 as a history each time the various control commands are transmitted. ing. In response to the storage of the control command data, the main control board 310 updates the history data in the data storage unit 311. Note that the history data is updated when a plurality of types of authentication information is generated, so that the processing load on the main control board 310 can be reduced. The peripheral board 330 stores the control command data as a history in the peripheral side storage unit 332 each time various control commands are received, and updates the peripheral side history data in the peripheral side storage unit 332.

  Next, an example of the transmission timing of the jackpot related commands (jackpot reach command, jackpot start command, jackpot command, jackpot end command) from the main control unit 201 to the effect control unit 202 in the pachinko gaming machine 100 is shown in FIG. To explain.

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

  In the following, a process for a jackpot reach command (when a jackpot reach command (see step S413 in FIG. 5) or a loss reach command (see step S419 in FIG. 5) is received) and a jackpot reach process will be described.

  First, the symbol variation process by the effect control unit 202 will be described with reference to the flowchart shown in FIG. The effect control unit 202 determines whether or not a symbol variation command is received from the main control unit 201 in step S701 shown in FIG. When it is determined that the symbol variation command has not been received (S701: No), the effect control unit 202 repeats this determination process to wait for the symbol variation command to be received. On the other hand, when determining that the symbol variation command has been received (S701: Yes), the effect control unit 202 acquires a random effect selection random number in step S702, and in step S703, based on the acquired random number, The type is selected, and the process proceeds to step S704. In step S704, the effect control unit 202 transmits an effect start command for each variable effect to the lamp control unit 251 and the audio control unit 252, and the process proceeds to step S705.

  In step S705, the effect control unit 202 determines whether the effect time has elapsed. If the effect control unit 202 determines that the effect time has elapsed (S705: Yes), the effect control unit 202 proceeds to the process of step S707. On the other hand, when it is determined that the effect time has not elapsed (S705: No), the effect control unit 202 determines whether or not a symbol stop command has been received from the main control unit 201 in step S706. And when it determines with the production | presentation control part 202 not receiving the symbol stop command (S706: No), it returns to the process of step S705 and repeats a series of processes. On the other hand, when determining that the symbol stop command has been received (S706: Yes), the effect control unit 202 transmits the effect stop command to the lamp control unit 251 and the voice control unit 252 in step S707, and according to this flowchart. End the process.

  Next, the big hitting process by the effect control unit 202 will be described with reference to the flowchart shown in FIG. The effect control unit 202 determines whether or not a jackpot start command (see step S416 in FIG. 5) is received from the main control unit 201 in step S801 shown in FIG. When it is determined that the jackpot start command has not been received (S801: No), the effect control unit 202 repeats this determination process to wait for reception of the jackpot start command. On the other hand, when determining that the jackpot start command has been received (S801: Yes), the effect control unit 202 transmits a jackpot start processing command to the lamp control unit 251 and the voice control unit 252 in step S802, and step S803. Move on to processing.

  In step S803, the effect control unit 202 determines whether or not a round-by-round jackpot command (see step S417 in FIG. 5) has been received from the main control unit 201. When it is determined that the jackpot command has not been received (S803: No), the effect control unit 202 repeats this determination process to wait for reception of the jackpot command. On the other hand, when determining that the jackpot command has been received (S803: Yes), the effect control unit 202 rounds corresponding to the round jackpot commands received by the lamp control unit 251 and the voice control unit 252 in step S804. Another processing command is transmitted, and the process proceeds to step S805.

  In step S805, the effect control unit 202 determines whether or not a jackpot end command (see step S418 in FIG. 5) has been received from the main control unit 201. When it is determined that the jackpot end command has not been received (S805: No), the effect control unit 202 repeats this determination process to wait for reception of the jackpot end command. On the other hand, if it is determined that the jackpot end command has been received (S805: Yes), the effect control unit 202 transmits a jackpot end processing command to the lamp control unit 251 and the voice control unit 252 in step S806, and this flowchart. The process by is terminated.

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

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

  In step S <b> 906, the lamp control unit 251 determines whether an effect stop command has been received from the effect control unit 202. When it is determined that the effect stop command has not been received (S906: No), the lamp control unit 251 waits for the reception of the effect stop command by repeating this determination process. On the other hand, if the lamp control unit 251 determines that an effect stop command has been received (S906: Yes), in step S907, the lamp control unit 251 stops the output of the lamp data and ends the process according to this flowchart.

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

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

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

(Authentication information data format)
Next, an example in which an authentication information signal different from the control signal 1010 described above has authentication information will be described. In the present embodiment, a description will be given on the assumption that the main control unit 201 outputs an authentication information signal to the peripheral unit to transmit the authentication information from the main control unit 201 to the peripheral unit.

  In FIG. 11, authentication information 1020 includes an identification unit 1021 and a data unit 1022. The identification unit 1021 is set with identification data that can identify the authentication information 1020. An example of the identification data is one type of authentication command. For example, hexadecimal values such as 0xA0 and 0xB0 are set. Thereby, the peripheral part can identify the authentication information 1020 based on the identification part 1021. The authentication command is differentiated from the control command data 1001 by using a command different from the control command of the control command data 1001 described above.

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

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

(Example of history generation method)
In the present embodiment, a case will be described in which the history data generation unit 312 of the main control board 310 and the peripheral side history data generation unit 333 of the peripheral board 330 switch the history generation method based on the history generation method information illustrated in FIG. 13. To do.

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

  The history data generation unit 312 and the peripheral side history data generation unit 333 switch a plurality of history generation methods indicated by the history generation method information by a common switching method determined in advance. As an example of the switching method, there are sequentially switching from the top, specifying the switching order, specifying the switching pattern, and the like. For example, when sequentially switching the history generation method information of FIG. 13A, first, the “addition” history generation method is used, and then the next “subtraction” history generation method according to the generation of the individual identification value. Switch to Further, when the history generation method information in FIG. 13A is switched by the switching pattern, the switching pattern is switched to the first, third, second, and fourth. Thus, if the switching method can be used in common, the switching method can be arbitrarily set.

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

  When the pachinko gaming machine 100 is powered on (turned on), the main control unit 201 executes the authenticated side processing shown in FIG. 14 and based on the control command stored in the data storage unit 311 in step S1201. It is determined whether or not a control command is generated. If the main control unit 201 determines that a control command has not been generated (S1201: No), the main control unit 201 proceeds to the process of step S1203. On the other hand, if the main control unit 201 determines that a control command has been generated (S1201: Yes), in step S1202, the history generation method data in the data storage unit 311 and the control command to be generated by the history generation method. Based on the data, history data is generated and stored in the data storage unit 311, and then the process proceeds to step S 1203.

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

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

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

  In step S1209, the main control unit 201 encrypts the authentication information 1020 generated this time with a predetermined encryption method with the peripheral unit, and in step S1210, based on the encrypted authentication information 1020. An authentication information signal is generated and transmitted from the transmission unit 316 to the peripheral unit, and then the process proceeds to step S1211. If encryption is not required between the main control unit 201 and the peripheral unit, the processing in step S1209 is deleted, and the authentication information 1020 is transmitted to the peripheral unit as it is.

  In step S1211, the main control unit 201 determines whether or not the pachinko gaming machine 100 is powered off. If the main control unit 201 determines that the power is not turned off (S1211: No), the main control unit 201 returns to the process of step S1201 and repeats a series of processes. On the other hand, when the main control unit 201 determines that the power is turned off (S1211: Yes), the process according to this flowchart ends.

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

  When the authentication processing shown in FIG. 15 is executed, the peripheral unit determines whether or not a control command has been received from the main control unit 201 with reference to the peripheral storage unit 332 in step S1301. When it is determined that the peripheral unit has not received the control command (S1301: No), the process proceeds to step S1303. On the other hand, when it is determined that the peripheral unit has received the control command (S1301: Yes), in step S1302, the history generation method data and the history generation method of the peripheral storage unit 332 are the same as the main control unit 201. Based on the control command data to be generated, peripheral history data is generated and stored in the peripheral storage unit 332, and then the process proceeds to step S1303.

  In step S <b> 1303, the peripheral unit determines whether the receiving unit 331 has received authentication information (authentication information signal) 1020 from the main control unit 201. If the peripheral unit determines that the authentication information 1020 has not been received (S1303: No), the process proceeds to step S1312. On the other hand, if it is determined that the authentication information 1020 has been received (S1303: Yes), the peripheral unit proceeds to the process of step S1304.

  In step S1304, the peripheral unit decrypts the received authentication information 1020 with a decryption method corresponding to the encryption method of the main control unit 201, extracts authentication data from the data unit 1022 of the authentication information 1020, and It memorize | stores in the memory | storage part 332, and it progresses to the process of step S1305 after that. If encryption is not required between the main control unit 201 and the peripheral unit, the decryption process in step S1304 is deleted.

  In step S1305, the peripheral unit determines that the authentication data is the history data (based on the determination result of whether or not the received authentication data matches the peripheral history data stored in advance in the peripheral storage unit 332). It is determined whether or not it is peripheral side history data). When the peripheral unit determines that the authentication data is history data (S1305: Yes), the control command received from the main control unit 201 is regular, and the continuity of communication is valid. In step S1306, authentication based on history data for the main control unit 201 is established, and then the process proceeds to step S1312.

  On the other hand, if the peripheral unit determines that the authentication data is not history data (S1305: No), in step S1307, does the authentication data match the expected value stored in advance in the peripheral side storage unit 332? Determine whether or not. If the peripheral unit determines that the authentication data matches the expected value (S1307: Yes), since the individual identification value received from the main control unit 201 is a normal one, in step S1308, the individual identification is performed. Authentication by value is established, and then the process proceeds to step S1309. In step S 1309, the peripheral unit switches one history generation method from among a plurality of predetermined history generation methods using the switching method in the same manner as the main control unit 201, so that the changed history generation method is obtained. The history generation method data in the peripheral storage unit 332 is updated, and then the process proceeds to step S1312. On the other hand, if the peripheral portion determines that the authentication data does not match the expected value (S1307: No), the authentication data does not match any of the peripheral history data and the expected value. In step S1311, for example, a notification signal is output from the speaker 262 (see FIG. 2) or the like, and then the process proceeds to step S1312.

  In step S1312, the peripheral unit determines whether or not the pachinko gaming machine 100 is powered off. If it is determined that the power source is not turned off (S1312: No), the peripheral unit 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 (S1312: Yes), the peripheral unit ends the process according to this flowchart.

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

  In FIG. 16, when the main control board 310 that is a person to be authenticated transmits a control command to the peripheral board 330 in accordance with the operation of the pachinko gaming machine 100, the control command is stored in the data storage unit 311 (S1401). Then, the main control board 310 generates history data based on the transmitted control command and the first history generation method and stores it in the data storage unit 311 (S1402). On the other hand, when the peripheral board 330 receives the control command, the peripheral board 330 stores the received control command in the peripheral-side storage unit 332 and performs a predetermined process corresponding to the control command (S1451). Then, similarly to the main control board 310, the peripheral board 330 generates peripheral side history data based on the received control command and the first history generation method, and stores it in the peripheral side storage unit 332 (S1452).

  Thereafter, when the main control board 310 randomly selects the history data of the history data and the individual identification value (S1403), the main control board 310 generates authentication information 1020 having the history data as authentication data and transmits it to the peripheral board 310. (S1404). On the other hand, since the authentication data of the received authentication information 1020 matches the peripheral history data, the peripheral board 330 performs authentication based on the continuity of control command communication with the main control board 310 (S1453).

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

  After that, when the main control board 310 randomly selects an individual identification value among the history data and the individual identification value (S1407), the main control board 310 generates authentication information 1020 having the individual identification value as authentication data and generates it on the peripheral board 310. Transmit (S1408). Then, the main control board 310 switches the first history generation method to the second history generation method and stores it in the data storage unit 311 (S1409). On the other hand, since the authentication data of the received authentication information 1020 matches the expected value, the peripheral board 330 performs authentication based on the individual authentication of the main control board 310 (S1456). Then, similarly to the main control board 310, the peripheral board 330 switches the first history generation method to the second history generation method and stores it in the peripheral storage unit 332 (S1457).

  When the main control board 310 transmits the next control command to the peripheral board 330, the main control board 310 stores the control command in the data storage unit 311 (S1410). Then, the main control board 310 generates history data based on the transmitted control command and the second history generation method and stores it in the data storage unit 311 (S1411). On the other hand, when the peripheral board 330 receives the control command, the peripheral board 330 stores the received control command in the peripheral-side storage unit 332 and performs a predetermined process corresponding to the control command (S1458). Then, similarly to the main control board 310, the peripheral board 330 generates peripheral side history data based on the received control command and the second history generation method, and stores it in the peripheral side storage unit 332 (S1459).

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

  According to the pachinko gaming machine 100 described above, the main control board 310 transmits authentication information 1020 having either history data indicating the history of control commands or individual identification values to the peripheral board 330, and has an individual identification value. Since the history generation method for generating history data in response to the transmission of the authentication information 1020 is switched, history data can be generated by switching the history generation method, making it difficult to analyze the history data generation method. In addition, it can be difficult to estimate whether the authentication information 1020 has history data or an individual identification value. Further, since the peripheral board 330 only has to switch the history generation method of the peripheral history data in the same manner as the main control board 310 in response to the reception of the authentication information 1020 having the individual identification value, it is easy to synchronize with the main control board 310, If fraud occurs in the authentication information 1020, the history generation methods do not match, which can contribute to fraud prevention. Since the peripheral board 310 is configured to confirm and authenticate the communication continuity of the control command based on the history data, it can detect unauthorized communication switching due to an unauthorized control command. It can contribute to prevention of switching. And since the history generation method is switched, the continuity of the history data to be generated is lost, and it is possible to make unauthorized analysis of history data difficult, so that unauthorized analysts use authentication information illegally. Can be prevented. Furthermore, since the individual identification value can be stored in advance, it is not necessary to perform a complicated calculation when generating the authentication information, and an increase in the processing load on the main control board 310 can be prevented. Therefore, the communication continuity of the control command can be confirmed, and the analysis of the authentication information 1020 used for authentication can be made difficult.

  In the pachinko gaming machine 100 described above, if the history data and the peripheral history data indicate the history of control commands for a plurality of times, even if the number of authentication information transmissions is reduced, fraudulent control commands that occurred during that time are detected. Therefore, it is possible to improve the authentication accuracy. Then, by setting the history data and the peripheral history data to values obtained by calculating past history data, analysis by an unauthorized analyst can be made even more difficult.

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

  The main control board 310 includes the data storage unit 311, the history data generation unit 312, the selection unit 313, the authentication information generation unit 314, the switching unit 315, the transmission unit 316, the counting unit 317 indicated by the broken line in FIG. It comprises and has.

  The counting unit 317 corresponds to the counting unit of the present invention, counts the number of appearances of the authentication information 1020 having the individual identification value, and stores the number of appearances in the data storage unit 311. Then, a switching condition indicating whether the switching unit 315 switches the history generation method based on the number of appearances is stored as a part of a program executed by the data storage unit 311 or the main control board 310. Then, the switching unit 315 is configured to switch the history generation method as described above when the number of appearances counted by the counting unit 317 satisfies the switching condition.

  The peripheral board 330 includes the receiving unit 331, the peripheral side storage unit 332, the peripheral side history data generation unit 333, the authentication unit 334, the peripheral side switching unit 335, the peripheral side counting unit 336 indicated by a broken line in FIG. It comprises and has.

  The peripheral side counting unit 336 corresponds to the peripheral side counting means of the present invention, counts the number of times the authentication information 1020 having the individual identification value from the main control board 310 is received, and stores the number of receptions in the peripheral side storage unit 332. To do. Then, a switching condition indicating whether or not the peripheral side switching unit 335 switches the history generation method based on the number of times of reception is stored as a part of a program executed by the peripheral side storage unit 332 and the peripheral board 330. This switching condition is the same switching condition as that of the main control board 310. Then, the peripheral side switching unit 335 is configured to switch the history generation method as described above when the number of receptions counted by the peripheral side counting unit 336 satisfies the switching condition.

  That is, the number of appearances of the counting unit 317 is the number of authentication information 1020 having an individual identification value transmitted from the main control board 310 to the peripheral board 330, and the number of receptions of the peripheral side counting part 336 is controlled by the peripheral board 330. This is the number of authentication information 1020 having the individual identification value received from the board 310. Therefore, the number of appearances counted by the counting unit 317 and the number of receptions counted by the peripheral side counting unit 336 are the same unless the unauthorized authentication information is generated. Therefore, the switching unit 315 and the peripheral side switching unit The switching of the history generation method can be synchronized by using a common switching condition in 335.

(Other processing related to transmission / reception of authentication information signal)
Below, the communication example of the said authentication information signal performed between the main control part 201 and a peripheral part in the structure mentioned above is demonstrated. First, an example of another transmission procedure of the authentication information signal by the CPU 211 (first computer) of the main control unit 201 will be described with reference to the flowchart of FIG. Note that the basic processing of the flowchart shown in FIG. 17 is the same as the flowchart shown in FIG. 14 described above, and therefore only different parts will be described.

  When the power of the pachinko gaming machine 100 is turned on (turned on), the main control unit 201 executes the authentication-side processing shown in FIG. In step S1222, the number of appearances of the individual identification value that has appeared is counted and stored in the data storage unit 311. Then, in step S1222, it is determined whether the counted number of appearances satisfies the switching condition. When the main control unit 201 determines that the number of appearances does not satisfy the switching condition (S1222: No), the main control unit 201 proceeds to the process of step S1209 described above. On the other hand, when the main control unit 201 determines that the number of appearances satisfies the switching condition (S1222: Yes), the main control unit 201 selects one of a plurality of predetermined history generation methods in the same manner as the process of step S1208 described above. The two history generation methods are switched by the switching method, the history generation method data in the data storage unit 311 is updated so as to be the switched history generation method, and then the process proceeds to step S1209 described above. Thereafter, the processes of steps S1209 to S1211 described above are executed.

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

  Next, a procedure of another reception process of the authentication information signal by the CPUs 241 and 281 (second computer) in the peripheral part will be described with reference to the flowchart of FIG. Since the basic processing of the flowchart shown in FIG. 18 is the same as the flowchart shown in FIG. 15 described above, only different parts will be described.

  When the authentication unit processing shown in FIG. 18 is executed, the peripheral unit ends the processing of steps S1301 to S1308. In step S1321, the peripheral unit counts the number of receptions of the received individual identification value and stores it in the peripheral storage unit 332. Thereafter, in step S1322, it is determined whether the counted number of receptions satisfies the switching condition. When it is determined that the number of receptions does not satisfy the switching condition (S1322: No), the peripheral unit proceeds to the process of step S1312 described above. On the other hand, when it is determined that the number of receptions satisfies the switching condition (S1322: Yes), the peripheral unit selects one history generation method from among a plurality of predetermined history generation methods as in step S1309 described above. Is switched by the switching method, the history generation method data in the peripheral storage unit 332 is updated so as to be the switched history generation method, and then the process proceeds to the above-described step S1312. Thereafter, the processes of steps S1310 to S1312 described above are executed.

  Next, an example of the operation of the pachinko gaming machine 100 configured as described above will be described. First, even if the main control board 310 generates the authentication information 1020 having the individual identification value, the history generation method is not immediately switched. Thereafter, the main control board 310 counts the number of appearances each time the authentication information 1020 having the individual identification value appears, and switches the history generation method when the number of appearances satisfies the switching condition. On the other hand, the peripheral board 330 does not immediately switch the history generation method even when the authentication information 1020 having the individual identification value is received. Thereafter, the peripheral board 330 counts the number of times of receiving the authentication information 1020 having the individual identification value, and switches the history generation method when the number of times of reception satisfies the switching condition.

  According to the pachinko gaming machine 100 described above, the main control board 310 transmits authentication information 1020 having either history data indicating the history of control commands or individual identification values to the peripheral board 330, and has an individual identification value. Since the history generation method for generating history data in response to the transmission of the authentication information 1020 is switched, history data can be generated by switching the history generation method, making it difficult to analyze the history data generation method. In addition, it can be difficult to estimate whether the authentication information 1020 has history data or an individual identification value. Further, since the peripheral board 330 only has to switch the history generation method of the peripheral history data in the same manner as the main control board 310 in response to the reception of the authentication information 1020 having the individual identification value, it is easy to synchronize with the main control board 310, If fraud occurs in the authentication information 1020, the history generation methods do not match, which can contribute to fraud prevention. Since the peripheral board 310 is configured to confirm and authenticate the communication continuity of the control command based on the history data, it can detect unauthorized communication switching due to an unauthorized control command. It can contribute to prevention of switching. And since the history generation method is switched, the continuity of the history data to be generated is lost, and it is possible to make unauthorized analysis of history data difficult, so that unauthorized analysts use authentication information illegally. Can be prevented. Furthermore, since the individual identification value can be stored in advance, it is not necessary to perform a complicated calculation when generating the authentication information, and an increase in the processing load on the main control board 310 can be prevented. Therefore, the communication continuity of the control command can be confirmed, and the analysis of the authentication information 1020 used for authentication can be made difficult.

  In the pachinko gaming machine 100 described above, the main control board 310 and the peripheral board 330 count the number of appearances and receptions of individual identification values, and switch the history generation method by the switching method when the number of times satisfies the switching condition. As a result, it is possible to further complicate the switching timing of the generated history data and the history generation method, so that unauthorized analysis can be made more difficult.

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

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

  For example, as shown in FIG. 19, the main control board 310 stores the switching information H1 in association with the individual identification value C1, and the switching information H2 in association with the individual identification value C2, and stores them in the data storage unit 311. The switching information H1 and H2 are set, for example, as “history generation method D1” and “history generation method D2,” “shift one”, “shift three”, and the like for a table indicating a plurality of history generation methods. The selection unit 313 described above randomly selects one of the three options of the history data, the individual identification value C1, and the individual identification value C2. The switching unit 315 described above uses a history generation method based on the switching information H1 when the selection unit 313 selects the individual identification value C1, and based on the switching information H2 when the selection unit 313 selects the individual identification value C2. Switch. Further, the peripheral board 330 stores the switching information H1 and H2 in association with the expected values B1 and B2 corresponding to the individual identification values C1 and C2 of the main control board 310 and stores them in the peripheral storage unit 332. The peripheral side switching unit 335 described above switches the switching information H1 when the authentication unit 334 establishes authentication by matching the individual identification value C1 and the expected value B1, and the authentication unit 334 determines that the individual identification value C2 and the expected value. When authentication is established by matching with B2, the history generation method is switched based on the switching information H2.

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

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

(Functional configuration of main control board and peripheral board)
First, as shown in FIG. 20, the pachinko gaming machine 100 has a main control board 310 having a function as the main control unit 201 and functions as peripheral units such as the above-described effect control unit 202 and prize ball control unit 203. And a peripheral substrate 330 having the same. The main control board 310 is electrically connected so as to communicate with the peripheral board 330.

  The main control board 310 includes the data storage unit 311, the history data generation unit 312, the switching unit 315, the transmission unit 316, the first authentication information generation unit 314a, the second authentication information generation unit 314b, and the determination unit 318. , And is configured.

  The first authentication information generation unit 314a corresponds to a first authentication information generation unit of the present invention, and the authentication information 1020 used by the peripheral board (peripheral part) 330 for authentication of the main control board (main control part) 310 is The history data generated by the history data generation unit 312 is generated so as to have authentication data. That is, the first authentication information generation unit 314a generates the authentication information 1020 of the data type K1 shown in FIG.

  The second authentication information generation unit 314b corresponds to a second authentication information generation unit of the present invention, and is stored in the data storage unit (individual identification value storage unit) 311 when the determination unit 318 described later switches. The authentication information 1020 is generated so as to have an individual identification value as the authentication data. That is, the second authentication information generation unit 314b generates the authentication information 1020 of the data type K2 shown in FIG.

  Note that the first authentication information generation unit 314a and the second authentication information generation unit 314b may be configured separately, or may be configured as a single unit, such as the authentication information generation unit 314 described above.

  The determination unit 318 corresponds to a determination unit of the present invention, and randomly determines whether or not to switch the history generation method of the history data generation unit 312. The determination unit 318 randomly determines whether or not to switch using a random number or the like so that the probability of occurrence of switching becomes a predetermined frequency. Then, the switching unit 315 determines the history generation method of the history data generation unit (history data generation unit) 312 from among a plurality of predetermined history generation methods in response to the determination by the determination unit 318 to switch. Switching is performed by a predetermined switching method, and the history generation method data in the data storage unit 311 is set. For example, the switching unit 315 can switch between two types of history generation methods, or switch a plurality of history generation methods in order.

  The transmitting unit 316 controls the authentication information 1020 having history data generated by the first authentication information generating unit 314a, the authentication information 1020 having the solid identification value generated by the second authentication information generating unit 314b, and the peripheral board 330. Each of the plurality of control commands to be transmitted is transmitted to the peripheral board (peripheral part) 330. The transmitter 316 transmits each piece of authentication information to the peripheral board 330 as the authentication information signal.

  Subsequently, the peripheral board 330 includes a receiving unit 331, a peripheral side storage unit 332, a peripheral side history data generation unit 333, an authentication unit 334, and a peripheral side switching unit 335, as in the first embodiment. . Since the peripheral substrate 330 can be realized with the same configuration as that of the first embodiment, the description thereof is omitted.

  The pachinko gaming machine 100 configured in this manner transmits authentication information in which either history data or individual identification value is set from the main control board 310 to the peripheral board 330, and the peripheral board 330 stores the history data of the authentication information. The authentication is performed based on the continuity of communication of the control command based on the control information, and the authentication is performed based on the individual identification of the main control board 310 based on the individual identification value of the authentication information. When the main control board 310 decides to switch randomly, the history generation system is switched by the switching system and the authentication information having the solid identification value is transmitted to the peripheral board 330. Since the history generation method is switched by the same switching method in response to reception of authentication information having an individual identification value, the history data of authentication information can be irregularly changed, so that unauthorized analysis of authentication information is performed. Can be difficult. Therefore, even if the authentication information is transmitted alone from the main control unit 201 to the peripheral board 330, it can be difficult to easily analyze it.

  In the present embodiment, a case will be described in which the CPU 211 of the main control board 310 functions as the first computer in the claims and each of the CPUs 241 and 281 of the peripheral board 330 functions as the second computer in the claims. The ROM 212 of the main control board 310 includes various data such as history data generation means, first authentication information generation means, second authentication information generation means, switching means, transmission means, determination means, etc. A main control side authentication program for functioning as a means is stored. Each of the ROMs 242 and 282 of the peripheral board 330 is a peripheral for causing the second computer to function as various means such as receiving means, peripheral history data generating means, authentication means, and peripheral switching means in the claims. Side authentication program is stored. That is, the authentication program of the present invention is constituted by the main control side authentication program and the peripheral side authentication program.

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

  When the power of the pachinko gaming machine 100 is turned on (turned on), the main control unit 201 executes the authenticated-side process shown in FIG. 21 and based on the control command stored in the data storage unit 311 in step S1501. It is determined whether or not a control command is generated. If the main control unit 201 determines that no control command has been generated (S1501: No), the main control unit 201 proceeds to the process of step S1503. On the other hand, if the main control unit 201 determines that a control command is generated (S1501: Yes), in step S1502, the history generation method data in the data storage unit 311 and the control command to be generated by the history generation method. Based on the data, history data is generated and stored in the data storage unit 311, and then the process proceeds to step S 1503.

  In step S1503, the main control unit 201 determines whether it is a predetermined authentication timing. If the main control unit 201 determines that it is not the authentication timing (S1503: No), the process proceeds to step S1511. On the other hand, if the main control unit 201 determines that it is the authentication timing (S1503: Yes), the process proceeds to step S1504.

  In step S1504, the main control unit 201 determines whether to switch the history generation method based on a random number or the like, stores the determination result in the RAM 213, etc., and then proceeds to the processing of step S1505. In step S1505, the main control unit 201 determines whether or not to switch based on the determination result. If the main control unit 201 determines that it has not been switched (S1505: No), authentication information in which authentication command C is set in the identification unit 1021 and history data as authentication data is set in the data unit 1022 in step S1506. (History data) 1020 is generated and stored in the data storage unit 311, and then the process proceeds to step S <b> 1509.

  On the other hand, if the main control unit 201 determines that it is determined to switch (S1505: Yes), in step S1507, the authentication command C is set in the identification unit 1021, and the individual identification value as authentication data is set in the data unit 1022. Authentication information (individual identification value) 1020 is generated and stored in the data storage unit 311, and then the process proceeds to step S 1508. In step S1508, the main control unit 201 switches one history generation method from among a plurality of predetermined history generation methods using the switching method, and the data storage unit 311 so that the switched history generation method is obtained. The history generation method data is updated, and then the process proceeds to step S1509.

  In step S1509, the main control unit 201 encrypts the authentication information 1020 generated this time using a predetermined encryption method with the peripheral unit, and in step S1510, based on the encrypted authentication information 1020. An authentication information signal is generated and transmitted from the transmission unit 316 to the peripheral unit, and then the process proceeds to step S1511. If encryption is not required between the main control unit 201 and the peripheral unit, the processing in step S1509 is deleted, and the authentication information 1020 is transmitted to the peripheral unit as it is.

  In step S1511, the main control unit 201 determines whether or not the pachinko gaming machine 100 is powered off. If the main control unit 201 determines that the power is not turned off (S1511: No), the main control unit 201 returns to the process of step S1501 and repeats a series of processes. On the other hand, when the main control unit 201 determines that the power is turned off (S1511: Yes), the process according to this flowchart ends.

  Subsequently, the authentication information signal reception processing procedure performed by the peripheral CPUs 241 and 281 (second computer) can use the authentication-side processing shown in FIG. To do.

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

  In FIG. 22, when the main control board 310 that is the person to be authenticated transmits a control command to the peripheral board 330 in accordance with the operation of the pachinko gaming machine 100, the control command is stored in the data storage unit 311 (S1601). Then, the main control board 310 generates history data based on the transmitted control command and the first history generation method and stores it in the data storage unit 311 (S1602). On the other hand, when the peripheral board 330 receives the control command, the peripheral board 330 stores the received control command in the peripheral-side storage unit 332 and performs a predetermined process corresponding to the control command (S1651). Then, similarly to the main control board 310, the peripheral board 330 generates peripheral history data based on the received control command and the first history generation method, and stores it in the peripheral storage unit 332 (S1652).

  Thereafter, when the main control board 310 randomly determines that the history generation method is not switched (S1603), the main control board 310 generates authentication information 1020 having history data associated in advance as authentication data without switching the history generation method. To the peripheral board 310 (S1604). On the other hand, since the authentication data of the received authentication information 1020 matches the peripheral history data, the peripheral board 330 performs authentication based on the continuity of control command communication with the main control board 310 (S1653).

  When the main control board 310 transmits the next control command to the peripheral board 330, the main control board 310 stores the control command in the data storage unit 311 (S1605). Then, the main control board 310 generates history data based on the transmitted control command and the first history generation method, and stores it in the data storage unit 311 (S1606). On the other hand, when the peripheral board 330 receives the control command, the peripheral board 330 stores the received control command in the peripheral-side storage unit 332 and performs a predetermined process corresponding to the control command (S1654). Then, similarly to the main control board 310, the peripheral board 330 generates peripheral side history data based on the received control command and the first history generation method, and stores it in the peripheral side storage unit 332 (S1655).

  After that, when switching the history generation method, the main control board 310 determines at random (S1607), and generates authentication information 1020 having an individual identification value associated in advance as the authentication data for switching the history generation method. The data is transmitted to the peripheral board 310 (S1608). Then, the main control board 310 switches the first history generation method to the second history generation method and stores it in the data storage unit 311 (S1609). On the other hand, since the authentication data of the received authentication information 1020 matches the expected value, the peripheral board 330 performs authentication based on the individual authentication of the main control board 310 (S1656). Then, similarly to the main control board 310, the peripheral board 330 switches the first history generation method to the second history generation method and stores it in the peripheral storage unit 332 (S1657).

  When the main control board 310 transmits the next control command to the peripheral board 330, the main control board 310 stores the control command in the data storage unit 311 (S1610). Then, the main control board 310 generates history data based on the transmitted control command and the second history generation method and stores it in the data storage unit 311 (S1611). On the other hand, when receiving the control command, the peripheral board 330 stores the received control command in the peripheral side storage unit 332 and performs a predetermined process corresponding to the control command (S1658). Then, similarly to the main control board 310, the peripheral board 330 generates peripheral side history data based on the received control command and the second history generation method, and stores it in the peripheral side storage unit 332 (S1659). Thereafter, the same processing is performed.

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

  According to the pachinko gaming machine 100 described above, as in the first embodiment, the main control board 310 transmits authentication information 1020 having either history data indicating the history of control commands or individual identification values to the peripheral board 330. Since the history generation method for generating history data is switched in response to the transmission of the authentication information 1020 having the individual identification value, the history data can be generated by switching the history generation method. Analysis of the generation method can be made difficult, and it can be made difficult to guess whether the authentication information 1020 has history data or an individual identification value. Further, since the peripheral board 330 only has to switch the history generation method of the peripheral history data in the same manner as the main control board 310 in response to the reception of the authentication information 1020 having the individual identification value, it is easy to synchronize with the main control board 310, If fraud occurs in the authentication information 1020, the history generation methods do not match, which can contribute to fraud prevention. Since the peripheral board 310 is configured to confirm and authenticate the communication continuity of the control command based on the history data, it can detect unauthorized communication switching due to an unauthorized control command. It can contribute to prevention of switching. And since the history generation method is switched, the continuity of the history data to be generated is lost, and it is possible to make unauthorized analysis of history data difficult, so that unauthorized analysts use authentication information illegally. Can be prevented. Furthermore, since the individual identification value can be stored in advance, it is not necessary to perform a complicated calculation when generating the authentication information, and an increase in the processing load on the main control board 310 can be prevented. Therefore, the communication continuity of the control command can be confirmed, and the analysis of the authentication information 1020 used for authentication can be made difficult.

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

  Further, in the present embodiment, a case where the first authentication information generation unit 314a generates authentication information 1020 having history data in response to the determination that the determination unit 318 of the main control board 310 does not switch the history generation method will be described. did. Instead of this, after the first authentication information generation unit 314a generates the authentication information 1020 having history data, the determination unit 318 may determine whether to switch the history generation method at a predetermined timing. it can. That is, the main control board 310 normally generates authentication information 1020 having history data, and generates authentication information 1020 having an individual identification value when the determination unit 318 determines to switch. With such a configuration, it is possible to reduce the communication frequency of the individual identification value and increase the communication frequency of the history data.

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

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