<P>PROBLEM TO BE SOLVED: To detect a fraudulent action to a main control board of a game machine and to reduce processing loads of the main control part. <P>SOLUTION: The game machine 1 includes the main control part 10 and a peripheral part 30. The main control part 10 includes: a data storage part 510 where game information is stored; a main CPU core 500 for carrying out an operation according to the game information; a first transmission part 520a and a second transmission part 520b for transmitting information to the peripheral part 30; and an encryption part 530 for generating authentication data by reading and encrypting an inspection value stored in the data storage part 510. When making the first transmission part 520a transmit a control command, the main CPU core 500 outputs a write signal of the control command and also writes the control command to the first transmission part 520a. With the output of the write signal as a trigger, the encryption part 530 writes the authentication data to the second transmission part 520b to be transmitted to the peripheral part 30. <P>COPYRIGHT: (C)2012,JPO&INPIT |
