<P>PROBLEM TO BE SOLVED: To detect a fraudulent act to a main control part 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 110, an intermediate control part 180 and a peripheral part 300. The main control part 110 includes: a main ROM 110b stored with predetermined game information and the initial setting information of the game machine; a main CPU 110a for performing an arithmetic operation according to the game information; an authentication information generation part 500 which uses a specific encryption circuit 502 of two or more kinds of encryption circuits 502 to encrypt an inspection value read from the main ROM 110b and generates authentication information; a first transmission part 520a for transmitting control information to the intermediate control part 180; and a second transmission part 520b for transmitting the authentication information. The main CPU 110a selects one of the plurality of encryption circuits 502 provided in the authentication information generation part 500 as one of the pieces of the initial setting information in boot processing, and the authentication information generation part 500 generates the authentication information using the selected encryption circuit 502. <P>COPYRIGHT: (C)2012,JPO&INPIT |
