<P>PROBLEM TO BE SOLVED: To provide a gaming machine detecting fraudulent act to a main control board and reducing a processing load of a main control unit. <P>SOLUTION: The gaming machine 1 includes: a data storage unit 510 for storing game information; a main CPU core 500 for calculation according to the game information; a transmission unit 520 for transmitting information to a presentation control unit 203; and an encryption unit 530 for reading and encrypting a check value stored in the data storage unit 510 and generating authentication data. The main CPU core 500 writes a control command into a data input unit 522 of the transmission unit 520 when transmitting the control command to the transmission unit 520, and outputs a write signal then. The encryption unit 530 writes the authentication data immediately after the control command written into a data input unit 522, with the write signal as the standard, in order to add the authentication data to the control command and transmit the authentication data. <P>COPYRIGHT: (C)2012,JPO&INPIT |
