Description

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

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

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

JP 11-333108 A

  However, when the above-described conventional technology is used, the alteration of the program data can be detected, but if an unauthorized control board is connected between the authorized main control board and the controlled board, this unauthorized control board is used. It is not possible to prevent unauthorized control by an unauthorized control signal output from.

  FIG. 24 is an explanatory diagram showing an outline of a fraud prevention technique according to the prior art. FIG. 25 is an explanatory diagram showing an example of inserting an unauthorized control board. 24 and 25, the unauthorized control will be described in detail with reference to the unauthorized control board. As shown in FIG. 24, the regular main control board 1501 normally sends the regular control signal RS to the peripheral board 1502. The output of the peripheral substrate 1502 is controlled. A regular main control board 1501 is provided with an inspection port 1503. The program data recorded in the ROM or the like provided inside the regular main control board 1501 is inspected from the inspection port 1503 to inspect whether the regular main control board 1501 is fraudulent.

  However, as shown in FIG. 25, an illegal control board 1601 may be inserted between the regular main control board 1501 and the peripheral board 1502 in order to perform illegal control of the gaming machine. The unauthorized control board 1601 discards or ignores the authorized control signal RS output from the authorized main control board 1501 and outputs an unauthorized control signal FS to the peripheral board 1502 instead.

  In the case of the prior art, the peripheral board 1502 cannot determine whether the input signal is the normal control signal RS or the illegal control signal FS. Therefore, when an unauthorized control signal FS is input to the peripheral board 1502, there is a problem that an unauthorized operation cannot be detected and an operation corresponding to the control content of the unauthorized control signal FS is performed.

  Further, since the inspection port 1503 is provided on the regular main control board 1501, even if the inspection using the inspection port 1503 is performed, the inspection result for the regular main control board 1501 is returned. Therefore, even if the inspection port 1503 is provided, there is a problem that unauthorized control by the unauthorized control board 1601 cannot be detected.

  FIG. 26 is an explanatory diagram showing an outline of signal switching by the signal switching circuit. As shown in FIG. 26, in an unauthorized control board 1601, a signal switching circuit 1603 may be mounted in addition to an unauthorized CPU 1602 that outputs an unauthorized control signal FS. When the signal switching circuit 1603 is mounted, the unauthorized control board 1601 causes the normal control signal RS to be output during initial diagnosis or inspection operation of the control signal RS output from the normal CPU 1504, and during other operations, It can be switched to output an unauthorized control signal FS. In other words, the normal control signal RS output from the normal CPU 1504 can be output only when the inspection using the inspection port 1503 or the operation diagnosis of the CPU is performed by the signal switching circuit 1603.

  For this reason, a new authentication method is being studied in which a legitimate main control board 1501 is authenticated by using data and signals different from the control of the peripheral board 1502 and an unauthorized control board 1601 is detected. However, for example, in an authentication method in which a single authentication data or authentication signal is independently transmitted from the regular main control board 1501 to the peripheral board 1502, it is easy for an unauthorized analyst to analyze, and it is necessary to make the analysis difficult. It was. In addition, if encryption is performed at the time of transmission, the processing of each of the regular main control board 1501 and the peripheral board 1502 becomes complicated, resulting in a problem that the processing load increases.

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

  In order to solve the above-described problems caused by the prior art, the present invention prevents the data transmitted from the main control unit to the peripheral unit from being used for unauthorized control without using complicated calculations and It is an object of the present invention to provide a gaming machine, a main control board, a peripheral board, a gaming machine authentication method, and a certification program that can reduce the processing load on the CPU.

Therefore, it is possible to prevent the data transmitted from the main control side to the peripheral side from being used for unauthorized control and reduce the processing load on the peripheral CPU without using complicated calculations. Further, even if the authentication process is complicated, it does not affect the effect process on the peripheral side, so that it is possible to improve both the security and the fun of the game.

  Also, in the gaming machine described above, since a plurality of effective authentication values can be set for a plurality of types of authentication information, the number of setting patterns used between the main control side and the intermediate unit is increased. Therefore, it is even more difficult for an unauthorized analyst to analyze multiple types of authentication information, preventing unauthorized analysts from using authentication information illegally, and unauthorized use of data by unauthorized analysts. This can be detected in the middle part. In addition, since the peripheral side only needs to refer to the intermediate authentication result without performing the authentication process, it is possible to reduce the processing added by the CPU on the peripheral side.

  Furthermore, in the gaming machine described above, it is possible to set invalid authentication data for all of a plurality of types of authentication information. In this case, the initial setting pattern is set as the next setting pattern. Therefore, it is possible to prevent unauthorized use and improve detection accuracy.

  Further, in the gaming machine described above, since the main control side transmits the plurality of types of authentication information to the intermediate unit in the order of the plurality of types of authentication information defined by the setting pattern, the intermediate unit includes a plurality of types of authentication information. Since authentication on the main control side can be performed based on the valid and invalid patterns of authentication data set in each piece of information and their order, the accuracy of authentication can be improved without using complicated calculations. .

  Furthermore, in the gaming machine described above, since the plurality of types of authentication information generated by the main control side are transmitted to the intermediate part in an irregular order, an unauthorized analyst analyzes the plurality of types of authentication information. It becomes even more difficult, and it is possible to prevent an unauthorized analyst from using the authentication information illegally, and to detect that the data is illegally used by the unauthorized analyst at the intermediate part.

Then, the peripheral side reception unit 351 receives the control signal from the intermediate unit 202A.

  The processing unit 352 corresponds to the processing means of the present invention, and performs predetermined processing in the pachinko gaming machine 100 according to the intermediate authentication result data received from the intermediate unit 202A. When the intermediate authentication result data indicates that authentication has been established, the processing unit 352 performs the predetermined processing corresponding to the control command indicated by the control signal received from the intermediate unit 202A, and indicates that authentication has not been established. Will alert you. The predetermined process is a process corresponding to a control command from the main control unit 201 in the pachinko gaming machine 100. For example, a loss process, a jackpot reach process, a jackpot start process, a jackpot round process, a jackpot end process, etc. Can be mentioned.

  In the present embodiment, a description will be given of a configuration in which data communicated between the intermediate unit 202A and the peripheral unit 202B is transmitted without encryption. However, as described in the main control board 310 and the intermediate unit 202A described above.

(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 202B every time a game ball wins the start winning opening 105, and the effect control unit 202B 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 202B when the occurrence of the jackpot is determined, and the effect control unit 202B aligns with a predetermined symbol and stops the variable display, Control is performed to open the special winning opening 109. The effect control unit 202B 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 202B 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 202B. 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 202B and the prize ball control unit 203, and the process proceeds to step S403. When the power-on command is transmitted by this processing, the effect control unit 202B 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 for instructing lamp lighting, sound output, demonstration screen display, 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 0 (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 202B, and the process of step S407 Migrate to

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

  In step S412, the main control unit 201 determines whether or not the jackpot determination random number is a jackpot random number. If the main control unit 201 determines that it is a jackpot random number (S412: Yes), in step S413, the main control unit 201 transmits a jackpot reach command (symbol variation command) to the effect control unit 202B. In step S414, the main control unit 201 determines whether or not 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, when 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 202B, and proceeds to the process of step S416.

  In step S416, the main control unit 201 transmits a jackpot start command to the effect control unit 202B. 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 202B. To do. Then, when transmission of the jackpot command for all the rounds is completed, the main control unit 201 transmits a jackpot end command to the effect control unit 202B in step S418, and the process proceeds to 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 a loss reach command (symbol variation command) to the effect control unit 202B. 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 202B, and proceeds to the process of step S422.

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

  Next, with reference to the drawing of FIG. 6, 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 202B in the pachinko gaming machine 100 is referred to. To explain.

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

  In the following, description will be given of a process when the symbol changes (when a jackpot reach command (see step S413 in FIG. 5) or a loss reach command (see step S419 in FIG. 5) is received) and a jackpot reach.

  First, the symbol variation process by the effect control unit (peripheral unit) 202B will be described with reference to the flowchart shown in FIG. The effect control unit 202B 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 202B waits for the symbol variation command to be received by repeating this determination process. On the other hand, if it is determined that the symbol change command has been received (S701: Yes), the effect control unit 202B acquires a random effect selection random number in step S702, and in step S703, the variable effect is selected based on the acquired random number. The type is selected, and the process proceeds to step S704. In step S704, the effect control unit 202B 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 202B determines whether or not the effect time has elapsed. When it is determined that the production time has elapsed (S705: Yes), the production control unit 202B 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 202B determines whether or not a symbol stop command has been received from the main control unit 201 in step S706. And when it determines with the effect control part 202B 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 202B 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. The process ends.

  Next, the big hitting process by the effect control unit 202B will be described with reference to the flowchart shown in FIG. The effect control unit 202B 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 202B waits for reception of the jackpot start command by repeating this determination process. On the other hand, if it is determined that the jackpot start command has been received (S801: Yes), the effect control unit 202B 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 202B 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 202B repeats this determination process to wait for the jackpot command to be received. On the other hand, when it is determined that the jackpot command has been received (S803: Yes), the effect control unit 202B has a round corresponding to the round jackpot command received by the lamp control unit 251 or the voice control unit 252 in step S804. Another processing command is transmitted, and the process proceeds to step S805.

  In step S805, the effect control unit 202B 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 202B waits for the reception of the jackpot end command by repeating this determination process. On the other hand, if it is determined that the jackpot end command has been received (S805: Yes), the effect control unit 202B 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 202B (during symbol variation) will be described. Then, the lamp control unit 251 determines whether or not an effect start command is received from the effect control unit 202B 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 S906, the lamp control unit 251 determines whether an effect stop command has been received from the effect control unit 202B. 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, description will be made on the assumption that the main control unit 201 outputs an authentication information signal to the intermediate unit 202A, thereby transmitting the authentication information from the main control unit 201 to the intermediate unit 202A.

  In FIG. 11, authentication information 1020 includes an identification unit 1021 and a data unit 1022. The identification unit 1021 is set with identification data that can identify the authentication information 1020. As an example of the identification data, there are a plurality of different types of authentication commands. For example, hexadecimal values such as 0xA0 and 0xB0 are set. Accordingly, the intermediate unit 202A can identify each of the plurality of types of authentication information 1020 based on the identification unit 1021. The authentication command can be differentiated from the control command data 1001 by using a command different from the control command of the control command data 1001 described above.

  In the data unit 1022, authentication data of either a valid authentication value or an invalid value used for authentication of the main control unit 201 is set based on the setting pattern described above. The authentication data includes valid data as valid data and invalid data as invalid data. In addition, when valid data is set in a plurality of authentication commands, for example, an authentication value is set only for a predetermined authentication command in which all authentication values are set, and other authentication commands are set in other cases. The authentication value can be set to various embodiments. Note that the data unit 1022 may have other configurations such as attaching other data to a valid authentication value or an invalid value.

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

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

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

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

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

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

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

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

  The intermediate unit 202A corresponding to this stores the expected values B1 to B4 that match the authentication values A1 to A4 in the intermediate storage unit 332 as shown in FIG. The intermediate unit 202A stores the setting patterns P1 to P4 corresponding to the authentication values A1 to A4 in association with the expected values B1 to B4, respectively. Thereby, the intermediate part 202A can identify one setting pattern P from the expected value B. The association between the expected values B1 to B4 and the setting patterns P1 to P4 of the present embodiment will be described on the assumption that the expected values B1 to B4 are associated with the pattern information D described above. An embodiment in which the data indicating the expected values B1 to B4 and the setting patterns P1 to P4 are associated with each other may be employed. In this case, a program corresponding to each of the setting patterns P1 to P4 is stored in advance, and when the setting pattern P1 to P4 is specified, the corresponding program is started, and each authentication corresponding to the setting pattern P1 to P4 is started. This can be dealt with by adopting an embodiment that performs processing such as data validity judgment. In the case of the setting pattern P2, the intermediate unit 202A of the present embodiment receives and sets invalid data in the data unit 1022 corresponding to the authentication command C1 and valid data in that order in the data unit 1022 corresponding to the authentication command C2. If it is, the case where the authentication of the main control unit 201 is established will be described, but instead of this, an embodiment in which the order does not matter can be adopted.

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

  When the power of the pachinko gaming machine 100 is turned on (turned on), the main control unit 201 executes an authenticated process shown in FIG. 17 and determines whether or not it is a predetermined authentication timing in step S1201. If the main control unit 201 determines that it is not the authentication timing (S1201: No), the process proceeds to step S1208. On the other hand, if the main control unit 201 determines that it is the authentication timing (S1201: Yes), the process proceeds to step S1202.

  In step S1202, the main control unit 201 sets the setting pattern set in the next setting pattern data in the data storage unit 311 as the current setting pattern, and then proceeds to the processing in step S1203. When a setting pattern is not set in the next setting pattern data, that is, in the first process, an initial setting pattern predetermined as an initial value in the pachinko gaming machine 100 is set as the current setting pattern.

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

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

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

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

  In step S1206, the main control unit 201 encrypts the generated plurality of types of authentication information 1020 with a predetermined encryption method with the intermediate unit 202A. In step S1207, the main control unit 201 encrypts the plurality of types of authentication information 1020. An authentication information signal is generated based on each of the authentication information 1020 and transmitted from the main control side transmission unit 316 to the intermediate unit 202A, and then the process proceeds to step S1208. If encryption is not required between the main control unit 201 and the intermediate unit 202A, the processing in step S1206 is deleted, and a plurality of types of authentication information 1020 are transmitted to the intermediate unit 202A as they are.

  In step S1208, the main control unit 201 determines whether or not the pachinko gaming machine 100 is powered off. If the main control unit 201 determines that the power is not turned off (S1208: No), the main control unit 201 returns to the process of step S1201 and repeats a series of processes. On the other hand, when the main control unit 201 determines that the power is turned off (S1208: Yes), the process according to this flowchart ends.

  Next, a procedure for receiving a plurality of types of authentication information by the CPU 231 (second computer) of the intermediate unit 202A will be described with reference to the flowchart of FIG.

  When executing the authentication-side process shown in FIG. 18, intermediate section 202A determines whether or not authentication information (authentication information signal) 1020 has been received from main control section 201 by receiving section 331 in step S1301. If the intermediate unit 202A determines that the authentication information 1020 has not been received (S1301: No), the process proceeds to step S1312. On the other hand, if the intermediate unit 202A determines that the authentication information 1020 has been received (S1301: Yes), the process proceeds to step S1302.

  In step S1302, the intermediate unit 202A decrypts the received authentication information 1020 using a decryption method corresponding to the encryption method of the main control unit 201, extracts the authentication data from the data unit 1022 of the authentication information 1020, and performs intermediate processing. The data is stored in the side storage unit 332 and the like, the reception counter of the intermediate side storage unit 332 is incremented (+1), and then the process proceeds to step S1303. If encryption is not required between the main control unit 201 and the intermediate unit 202A, the decryption process in step S1302 is deleted. In the present embodiment, a case is described in which reception of one set of authentication information described above is confirmed using a reception counter. Instead of this, for example, a different set of embodiments such as using one set of flag data is used. can do.

  In step S1303, the intermediate unit 202A compares the extracted authentication data with a plurality of expected values in the intermediate storage unit 332 and determines whether the authentication data matches the expected value. If the intermediate unit 202A determines that the authentication data matches the expected value (S1303: Yes), since the authentication data is valid, the intermediate unit 202A is set in the identification unit 1021 of the received authentication information 1020 in step S1304. Valid data indicating “valid” is associated with the authentication command C being set in the validity determination result information of the intermediate storage unit 332 and the like, and then the process proceeds to step S1306. The validity determination result information has a data structure in which a plurality of authentication commands and validity / invalidity can be set as a pair of data. On the other hand, if the intermediate unit 202A determines that the authentication data does not match the expected value (S1303: No), the authentication data is invalid, and thus the identification unit 1021 of the received authentication information 1020 receives the authentication data in step S1305. Invalid data indicating “invalid” is associated with the set authentication command C and set in the validity determination result information of the intermediate storage unit 332 and the like, and then the process proceeds to step S1306.

  Whether the intermediate unit 202A has received all the authentication information 1020 from the main control unit 201 by comparing the reception counter of the intermediate storage unit 332 with the number of patterns (the number of authentication commands) indicated by the setting pattern in step S1306 Determine whether or not. If the intermediate unit 202A determines that all authentication information 1020 has not been received (S1306: No), the process proceeds to step S1312. On the other hand, if the intermediate unit 202A determines that all the authentication information 1020 has been received (S1306: Yes), the intermediate unit 202A clears the reception counter of the intermediate storage unit 332, and then proceeds to the processing of step S1307.

  In step S1307, the intermediate unit 202A determines whether the validity determination result indicated by the validity determination result information in the intermediate storage unit 332 or the like matches the current setting pattern. As an example of the determination method, it is determined whether the validity / invalidity determination result corresponding to a plurality of types of authentication commands C and the validity / invalidity of the authentication command C indicated by the setting pattern completely match. . When the order of a plurality of types of authentication information 1020 is added to the authentication determination, it is determined whether or not the validity determination result information is set according to the order of the authentication command C indicated by the setting pattern.

  If it is determined that the intermediate unit 202A matches the current setting pattern (S1307: Yes), in step S1308, authentication for the main control unit 201 is established, intermediate authentication result data indicating the establishment of authentication is generated, and stored in the RAM 233 or the like. Then, the process proceeds to step S1309. In step S1309, the intermediate unit 202A identifies the setting pattern associated with the expected value that matches the authentication data determined to be valid in the current authentication process, and uses the identified setting pattern as the next setting pattern. The next set pattern data in the side storage unit 332 is set, and then the process proceeds to step S1311.

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

  On the other hand, if the intermediate unit 202A determines in step S1307 that it does not match the current setting pattern (S1307: No), in step S1310, authentication for the main control unit 201 is not established, and an intermediate authentication result indicating that authentication is not established. Data is generated and stored in the RAM 233 or the like, and then the process proceeds to step S1311.

  In step S1311, the intermediate unit 202A sets the generated intermediate authentication result data in the result unit 1032 to generate intermediate authentication result information 1030, and generates an intermediate authentication result signal with the intermediate authentication result information 1030 added thereto. Transmission is performed from the transmission unit 335 to the peripheral unit 202B, and then the process proceeds to step S1312.

  In step S1312, the intermediate unit 202A 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 is turned off (S1312: Yes), the intermediate unit 202A ends the process according to this flowchart.

  Next, the procedure of receiving various control signals and intermediate authentication result signals by the CPU 241 (third computer) of the peripheral unit 202B will be described with reference to the flowchart of FIG.

  In step S1401, the peripheral unit 202B determines whether or not the control signal 1010 has been received from the intermediate unit 202A. If it is determined that the control signal 1010 has been received (S1401: Yes), the peripheral unit 202B performs predetermined processing based on the control command data 1001 and the accompanying data 1002 included in the received control signal 1010 in step S1402. Thereafter, the process proceeds to step S1405.

  On the other hand, when it is determined that the peripheral unit 202B has not received the control signal 1010 (S1401: No), in step S1403, based on whether or not the received signal includes the identification unit 1031, the intermediate unit It is determined whether an intermediate authentication result signal is received from 202A. If the peripheral unit 202B determines that the intermediate authentication result signal has not been received (S1403: No), the process proceeds to step S1405. On the other hand, if it is determined that the intermediate authentication result signal is received (S1403: Yes), the peripheral unit 202B proceeds to the process of step S1404.

  In step S1404, the peripheral unit 202B refers to the result unit 1032 of the received intermediate authentication result signal, and determines whether or not the intermediate authentication result signal indicates that authentication has been established. If the peripheral unit 202B determines that the intermediate authentication result indicates that authentication has been established (S1404: Yes), the peripheral unit 202B stores the authentication result in the RAM 243 or the like, and then proceeds to the processing of step S1405.

  In step S1405, the peripheral unit 202B determines whether or not the pachinko gaming machine 100 is powered off. If it is determined that the power is not turned off (S1405: No), the peripheral unit 202B returns to the process of step S1401 and repeats a series of processes. On the other hand, when it is determined that the power is turned off (S1405: Yes), the peripheral unit 202B ends the process according to this flowchart.

  On the other hand, if it is determined in step S1404 that the intermediate authentication result does not indicate that authentication has been established (S1405: No), the peripheral unit 202B outputs a notification signal from, for example, the speaker 262 (see FIG. 2) or the like in step S1406. Then, the process according to this flowchart is terminated. As for the processing of the peripheral portion 202B when the intermediate authentication result does not indicate that authentication has been established, that is, when authentication has not been established, the processing of the peripheral portion 202B is continued only by outputting a notification signal. Also good.

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

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

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

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

  On the other hand, when the intermediate section 202A of the peripheral board 330 receives a plurality of types of authentication information 1020C1 and C2 from the main control board 310 (S1511), each of the authentication commands C1 and C2 set in the identification section 1021 of the authentication information 1020C1 and C2 In addition, it is determined whether the authentication data is valid based on whether or not the authentication data of the data unit 1022 and the plurality of expected values stored in the intermediate storage unit 332 match, and the determination result Is set in the validity determination result information of the intermediate storage unit 332 or the like (S1512). Then, the intermediate unit 202A determines whether or not the determination result indicated by the validity determination result information matches the current setting pattern P1 that is the initial value, and the authentication result of the main control board 310 based on the determination result. Intermediate authentication result information 1030 having intermediate authentication result data is generated, and an intermediate authentication result signal with the intermediate authentication result information 1030 added is transmitted to the peripheral portion 202B of the peripheral board 330 (S1513). In this case, the intermediate unit 202A establishes authentication of the main control board 310 when both of the authentication commands C1 and C2 are invalid. When the authentication of the main control board 310 is established, the intermediate unit 202A sets the predetermined setting pattern P2 as the next setting pattern because no authentication value is set in the authentication information 1020C1 and C2 received this time. And the next set pattern data in the intermediate storage unit 332 is set (S1514), and the second and subsequent authentication processes are performed.

  Further, the peripheral portion 202B of the peripheral board 330 receives the control received from the main control portion 201 via the intermediate portion 202A when the intermediate authentication result information 1030 of the intermediate authentication result signal received from the intermediate portion 202A indicates that authentication has been established. A predetermined signal corresponding to the command data 1001 and the accompanying data 1002 can be executed, and if the intermediate authentication result information 1030 does not indicate that authentication has been established, a notification signal is output (S1521).

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

  The main control board 310 sets the authentication commands C1 and C2 in the order corresponding to the current setting pattern P2 in each of the identification units 1021 of the plurality of types of authentication information 1020, and the current setting pattern P2 is the authentication command C1. , C2 indicate invalid data and valid data settings, the data portion 1022 corresponding to each of the authentication commands C1, C2 includes invalid data different from the authentication value A3 and valid data that is the authentication value A3. Are sequentially set as authentication data, and a plurality of types of authentication information 1020C1 and C2 matching the current setting pattern P2 are generated (S1534). Then, the main control board 310 transmits authentication information 1020C1 and C2 in which valid data is set on one side to the peripheral board 330 (S1535).

  On the other hand, when the intermediate section 202A of the peripheral board 330 receives a plurality of types of authentication information 1020C1 and C2 from the main control board 310 (S1541), each authentication command C1 and C2 set in the identification section 1021 of the authentication information 1020C1 and C2 In addition, it is determined whether the authentication data is valid based on whether or not the authentication data of the data unit 1022 and the plurality of expected values stored in the intermediate storage unit 332 match, and the determination result Is set in the validity determination result information of the intermediate storage unit 332 or the like (S1542). Then, the intermediate unit 202A determines whether or not the determination result indicated by the validity determination result information matches the current setting pattern P2 specified as the next setting pattern in the previous authentication process. Based on this, the main control board 310 is authenticated (S1543). In this case, the intermediate unit 202A establishes authentication of the main control board 310 when the authentication command C1 is invalid and the authentication command C2 is valid. Then, when the authentication of the main control board 310 is established, the intermediate unit 202A has a setting pattern P3 associated with the expected value B3 of the intermediate storage unit 332 that matches the authentication data (authentication value A3) determined to be valid. It is specified and set in the next set pattern data of the intermediate storage unit 332 (S1544), and the subsequent authentication processing is performed.

  Further, the peripheral portion 202B of the peripheral board 330 receives the control received from the main control portion 201 via the intermediate portion 202A when the intermediate authentication result information 1030 of the intermediate authentication result signal received from the intermediate portion 202A indicates that authentication has been established. A predetermined process corresponding to the command data 1001 and the accompanying data 1002 can be executed, and if the intermediate authentication result information 1030 does not indicate that authentication has been established, a notification signal is output (S1551).

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

  According to the pachinko gaming machine 100 described above, a plurality of types of setting patterns P1 to P4 and a plurality of types of authentication values A1 to A4 are associated one-to-one, and the main control unit 201 becomes the current setting pattern P. As described above, the authentication value A corresponding to the next setting pattern P is set to generate a plurality of types of authentication information 1020, and the plurality of types of authentication information 1020 are transmitted to the intermediate unit 202A. 202A authenticates the main control unit 201 based on the valid authentication value A setting patterns P1 to P4 set in the plural types of authentication information 1020, so that an unauthorized analyst analyzes the plural types of authentication information 1020. It is difficult to do so, and it is possible to prevent an unauthorized analyst from using the authentication information 1020 illegally, and the fact that the data has been used illegally by the unauthorized analyst 202A It can be detected. Furthermore, since the number of setting patterns P1 to P4 can be increased by increasing the number of plural types of authentication information 1020, the authentication strength can be increased. In addition, the intermediate unit 202A identifies the setting pattern corresponding to the authentication value A from the expected value B and sets the next setting pattern P1 to P4, so that the switching of the setting pattern P1 to P4 in the pachinko gaming machine 100 is illegal. This makes it more difficult for an analyst to analyze. Furthermore, since a plurality of types of authentication values A can be stored in advance, it is not necessary to perform complicated calculations when generating the authentication information 1020, so that an increase in processing load on the main control unit 201 can be prevented. Since the intermediate unit 202A performs the authentication process for the main control unit 201 and transmits the intermediate authentication result to the peripheral unit 202B, the peripheral unit 202B only needs to refer to the intermediate authentication result without performing the authentication process. Therefore, the processing addition of the CPU 241 in the peripheral portion 202B can be reduced. Therefore, it is possible to prevent the data transmitted from the main control unit 201 to the peripheral unit 202B from being used for unauthorized control and reduce the processing load on the CPU 241 of the peripheral unit 202B without using complicated calculations. Further, even if the authentication process is complicated, it does not affect the effect process by the peripheral portion 202B, so that both the improvement of security and the fun of the game can be achieved.

  In the pachinko gaming machine 100 described above, since a plurality of valid authentication values A can be set for a plurality of types of authentication information 1020, a setting pattern used between the main control unit 201 and the intermediate unit 202A. Since the number of Ps can be increased, it becomes even more difficult for an unauthorized analyst to analyze a plurality of types of authentication information 1020, and an unauthorized analyst can be prevented from using the authentication information 1020 illegally. The fraudulent analyst can detect at the periphery that the data has been used illegally.

  Furthermore, in the pachinko gaming machine 100 described above, it is possible to set invalid authentication data for all of a plurality of types of authentication information 1020, in which case the initial setting pattern is set to the next setting pattern P. Therefore, the analysis of the switching of the setting pattern P can be made more difficult, so that unauthorized use can be prevented and detection accuracy can be improved.

  Further, in the pachinko gaming machine 100 described above, if the main control unit 201 transmits the plurality of types of authentication information 1020 to the intermediate unit 202A in the order of the plurality of types of authentication information 1020 defined by the setting pattern P, The intermediate unit 202A can perform authentication of the main control unit 201 based on the valid and invalid patterns and the order of the authentication data set in each of a plurality of types of authentication information 1020, so that complicated calculations are not used. Therefore, it is possible to improve the authentication accuracy.

  Furthermore, in the pachinko gaming machine 100 described above, if the plurality of types of authentication information 1020 generated by the main control unit 201 are transmitted to the intermediate unit 202A in an irregular order, an unauthorized analyst may use a plurality of types of authentication information. It is even more difficult to analyze 1020, and it is possible to prevent an unauthorized analyst from using the authentication information 1020 illegally and to detect that the data is illegally used by the unauthorized analyzer by the intermediate unit 202A. it can.

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

(Functional configuration of main control board and peripheral board)
First, the pachinko gaming machine 100 includes the control unit 200 shown in FIG. The control unit 200 includes a main control unit 201, an intermediate unit 202A, an effect control unit 202B, and a prize ball control unit 203. As shown in FIG. 19, the pachinko gaming machine 100 includes a main control board 310 having a function as the main control unit 201, and a peripheral board 330 having the intermediate unit 202A and the effect control unit 202B described above. Is configured. The main control board 310 is electrically connected so as to communicate with the peripheral board 330.

  The main control board 310 includes the data storage unit 311, the determination unit 312, the authentication information generation unit 315, the main control side transmission unit 316, and the selection unit 313 described above.

  The selection unit 313 corresponds to the selection unit of the present invention, and randomly selects one authentication value from a plurality of types of authentication values stored in the data storage unit 311. The selection unit 313 selects one authentication value using a random number or the like. In addition, the selection part 313 can also select the some authentication value according to the number, when the setting pattern has shown the setting of effective data to several authentication information.

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

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

  Similarly to the first embodiment, the pachinko gaming machine 100 according to the second embodiment also combines authentication information in which a valid authentication value is set and invalid authentication information, and transmits the combination from the main control board 310 to the intermediate section 202A of the peripheral board 330. The intermediate unit 202A employs a configuration for authenticating the main control board 310 based on the setting patterns of the plurality of types of authentication information. Therefore, the pachinko gaming machine 100 can improve security by authenticating by combining a plurality of types of setting patterns, and it is easy to send authentication information from the main control unit 201 to the peripheral board 330 alone. Can be difficult to analyze.

  Subsequently, the intermediate unit 202A of the peripheral board 330 illustrated in FIG. 21 is similar to the first embodiment in that the intermediate side reception unit 331, the intermediate side storage unit 332, the validity determination unit 333, the intermediate authentication result data generation unit 334, and the like. An intermediate transmission unit 335 and a specifying unit 336 are included. The peripheral portion 202B also includes the peripheral-side receiving portion 351 and the processing portion 352 described above as in the first embodiment. As described above, the peripheral substrate 330 can be realized by the same configuration as that of the first embodiment, and thus the description thereof is omitted.

  In the present embodiment, the CPU 211 of the main control board 310 is the first computer in the claims, and the CPU 231 of the intermediate section 202A of the peripheral board 330 is the second computer of the claims, and the CPU 241 of the effect control section 202B of the peripheral board 330. Will be described as functioning as the third computer in the claims. The ROM 212 of the main control board 310 is a main control side authentication program for causing the first computer to function as various means such as selection means, authentication information generation means, main control side transmission means, and determination means in the claims. Is remembered. The ROM 232 of the intermediate portion 202A of the peripheral board 330 includes the intermediate computer receiving means, validity determining means, intermediate authentication result data generating means, intermediate transmitting means, specifying means, etc. The intermediate side authentication program for functioning as various means is stored. Further, the ROM 242 of the peripheral portion 202B of the peripheral board 330 stores a peripheral side authentication program for causing the third computer to function as various means such as peripheral side receiving means and processing means in the claims. That is, the authentication program of the present invention is constituted by the main control side authentication program, the intermediate side authentication program, and the peripheral side authentication program.

(Processing for sending and receiving authentication information signals)
Hereinafter, a communication example of the authentication information signal performed between the main control unit 201 and the intermediate unit 202A will be described. First, an example of the authentication information signal transmission procedure 2 by the CPU 211 (first computer) of the main control unit 201 will be described with reference to the flowchart of FIG.

  When the power of the pachinko gaming machine 100 is turned on (turned on), the main control unit 201 executes an authenticated process shown in FIG. 22 and determines in step S1601 whether or not it is a predetermined authentication timing. If the main control unit 201 determines that it is not the authentication timing (S1601: No), the main control unit 201 proceeds to the process of step S1608. On the other hand, if the main control unit 201 determines that it is the authentication timing (S1601: Yes), the process proceeds to step S1602.

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

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

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

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

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

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

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

  Subsequently, the authentication information signal reception processing procedure performed by the CPU 231 (second computer) of the intermediate unit 202A on the peripheral board 330, and the control signal and the intermediate authentication performed by the CPU 241 (third computer) of the peripheral unit 202B. As the result signal reception processing procedure, the authentication side processing shown in FIG. 18 of the first embodiment and the processing shown in FIG.

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

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

  The main control board 310 sets the authentication commands C1 and C2 in the order corresponding to the current setting pattern P2 in each of the identification units 1021 of the plurality of types of authentication information 1020, and the current setting pattern P2 is the authentication command C1. , C2 indicate invalid data and valid data settings, the data portion 1022 corresponding to each of the authentication commands C1, C2 includes invalid data different from the authentication value A3 and valid data that is the authentication value A2. Are sequentially set as authentication data, and a plurality of types of authentication information 1020C1 and C2 matching the current setting pattern P2 are generated (S1703). Then, the main control board 310 transmits authentication information 1020C1 and C2 in which valid data is set on one side to the intermediate portion 202A of the peripheral board 330 (S1704). Then, the main control board 310 determines the setting pattern P2 associated with the selected authentication value A2 as the next setting pattern used for the next authentication of the main control board 310, and the result is the next time in the data storage unit 311. The setting pattern data is set (S1705). That is, the main control board 310 continues to use the setting pattern P2 in the next authentication process.

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

  On the other hand, when the intermediate section 202A of the peripheral board 330 receives a plurality of types of authentication information 1020C1 and C2 from the main control board 310 (S1711), each of the authentication commands C1 and C2 set in the identification section 1021 of the authentication information 1020C1 and C2 In addition, it is determined whether the authentication data is valid based on whether or not the authentication data of the data unit 1022 and the plurality of expected values stored in the intermediate storage unit 332 match, and the determination result Is set in the validity determination result information of the intermediate storage unit 332 or the like (S1712). Then, the intermediate unit 202A determines whether or not the determination result indicated by the validity determination result information matches the current setting pattern P1 that is the initial value, and the authentication result of the main control board 310 based on the determination result. Intermediate authentication result information 1030 having intermediate authentication result data is generated, and an intermediate authentication result signal to which the intermediate authentication result information 1030 is added is transmitted to the peripheral portion 202B of the peripheral board 330 (S1713). In this case, the peripheral board 330 establishes authentication of the main control board 310 when the authentication command C1 is invalid and the authentication command C2 is valid. Then, the intermediate unit 202A identifies the setting pattern P2 associated with the expected value B2 of the intermediate storage unit 332 that matches the authentication data (authentication value A2) determined to be valid, and the next setting of the intermediate storage unit 332 The pattern data is set (S1714), and the second and subsequent authentication processes are performed.

  Further, the peripheral portion 202B of the peripheral board 330 receives the control received from the main control portion 201 via the intermediate portion 202A when the intermediate authentication result information 1030 of the intermediate authentication result signal received from the intermediate portion 202A indicates that authentication has been established. A predetermined process corresponding to the command data 1001 and the accompanying data 1002 can be executed, and if the intermediate authentication result information 1030 does not indicate that authentication has been established, a notification signal is output (S1721).

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

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

  On the other hand, when the intermediate section 202A of the peripheral board 330 receives a plurality of types of authentication information 1020C1 and C2 from the main control board 310 (S1741), each of the authentication commands C1 and C2 set in the identification section 1021 of the authentication information 1020C1 and C2 In addition, it is determined whether the authentication data is valid based on whether or not the authentication data of the data unit 1022 and the plurality of expected values stored in the intermediate storage unit 332 match, and the determination result Is set in the validity determination result information of the intermediate storage unit 332 or the like (S 1742). Then, the intermediate unit 202A determines whether or not the determination result indicated by the validity determination result information matches the current setting pattern P2, and the intermediate authentication result indicating the authentication result of the main control board 310 based on the determination result. Intermediate authentication result information 1030 having data is generated, and an intermediate authentication result signal to which the intermediate authentication result information 1030 is added is transmitted to the peripheral portion 202B of the peripheral board 330 (S1743). In this case, the intermediate unit 202A establishes authentication of the main control board 310 when the authentication command C1 is invalid and the authentication command C2 is valid. Then, the intermediate unit 202A specifies the setting pattern P4 associated with the expected value B4 of the intermediate storage unit 332 that matches the authentication data (authentication value A4) determined to be valid, and the next setting of the intermediate storage unit 332 The pattern data is set (S1744), and subsequent authentication processing is performed.

  Further, the peripheral portion 202B of the peripheral board 330 receives the control received from the main control portion 201 via the intermediate portion 202A when the intermediate authentication result information 1030 of the intermediate authentication result signal received from the intermediate portion 202A indicates that authentication has been established. A predetermined process corresponding to the command data 1001 and the accompanying data 1002 can be executed, and if the intermediate authentication result information 1030 does not indicate that authentication has been established, a notification signal is output (S1751).

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

  According to the pachinko gaming machine 100 described above, a plurality of types of setting patterns P1 to P4 and a plurality of types of authentication values A1 to A4 are associated one-to-one, and the main control unit 201 becomes the current setting pattern P. As described above, the authentication value A corresponding to the next setting pattern P is set to generate a plurality of types of authentication information 1020, and the plurality of types of authentication information 1020 are transmitted to the intermediate unit 202A. 202A authenticates the main control unit 201 based on the valid authentication value A setting patterns P1 to P4 set in the plural types of authentication information 1020, so that an unauthorized analyst analyzes the plural types of authentication information 1020. It is difficult to do so, and it is possible to prevent an unauthorized analyst from using the authentication information 1020 illegally, and the fact that the data has been used illegally by the unauthorized analyst 202A It can be detected. Furthermore, since the number of setting patterns P1 to P4 can be increased by increasing the number of plural types of authentication information 1020, the authentication strength can be increased. In addition, the intermediate unit 202A identifies the setting pattern corresponding to the authentication value A from the expected value B and sets the next setting pattern P1 to P4, so that the switching of the setting pattern P1 to P4 in the pachinko gaming machine 100 is illegal. This makes it more difficult for an analyst to analyze. Furthermore, since a plurality of types of authentication values A can be stored in advance, it is not necessary to perform complicated calculations when generating the authentication information 1020, so that an increase in processing load on the main control unit 201 can be prevented. Since the intermediate unit 202A performs the authentication process for the main control unit 201 and transmits the intermediate authentication result to the peripheral unit 202B, the peripheral unit 202B only needs to refer to the intermediate authentication result without performing the authentication process. Therefore, the processing addition of the CPU 241 in the peripheral portion 202B can be reduced. Therefore, it is possible to prevent the data transmitted from the main control unit 201 to the peripheral unit 202B from being used for unauthorized control and reduce the processing load on the CPU 241 of the peripheral unit 202B without using complicated calculations. Further, even if the authentication process is complicated, it does not affect the effect process by the peripheral portion 202B, so that both the improvement of security and the fun of the game can be achieved.

  In the pachinko gaming machine 100 described above, since a plurality of valid authentication values A can be set for a plurality of types of authentication information 1020, a setting pattern used between the main control unit 201 and the intermediate unit 202A. Since the number of Ps can be increased, it becomes even more difficult for an unauthorized analyst to analyze a plurality of types of authentication information 1020, and an unauthorized analyst can be prevented from using the authentication information 1020 illegally. The fraudulent analyst can detect at the periphery that the data has been used illegally.

  Furthermore, in the pachinko gaming machine 100 described above, it is possible to set invalid authentication data for all of a plurality of types of authentication information 1020, in which case the initial setting pattern is set to the next setting pattern P. Therefore, the analysis of the switching of the setting pattern P can be made more difficult, so that unauthorized use can be prevented and detection accuracy can be improved.

  Further, in the pachinko gaming machine 100 described above, if the main control unit 201 transmits the plurality of types of authentication information 1020 to the intermediate unit 202A in the order of the plurality of types of authentication information 1020 defined by the setting pattern P, The intermediate unit 202A can perform authentication of the main control unit 201 based on the valid and invalid patterns and the order of the authentication data set in each of a plurality of types of authentication information 1020, so that complicated calculations are not used. Therefore, it is possible to improve the authentication accuracy.

  Furthermore, in the pachinko gaming machine 100 described above, if the plurality of types of authentication information 1020 generated by the main control unit 201 are transmitted to the intermediate unit 202A in an irregular order, an unauthorized analyst may use a plurality of types of authentication information. It is even more difficult to analyze 1020, and it is possible to prevent an unauthorized analyst from using the authentication information 1020 illegally and to detect that the data is illegally used by the unauthorized analyzer by the intermediate unit 202A. it can.
