GAME MACHINE, AUTHENTICATION METHOD AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To solve the problem of restriction in designing inevitably caused by a larger strength of security in the conventional game machines.SOLUTION: A control command and control data for controlling a performance or the pre-processing or the post processing of the performance pertaining to a game, an authentication data for attesting own authenticity and an order information for the execution by a CPU are outputted from the main control part 2a. A peripheral part 3a attests the authenticity for the connection state of the main control part using the order information while controlling the execution of the performance or the pre-processing or the post-processing of it based on the control command and outputs the authentication data. An authentication part 3b determines whether the main control part 2a is authentic or not, based on the authentication data outputted from the peripheral part 3a. The peripheral part 3a makes a notification to the effects if it is determined not to be authentic. The authentication part is thus arranged to attest the authenticity of the main control part and can reduce the burden on the peripheral part, thereby enabling the determination on whether the main control part is authentic or not with a larger strength of security than ever.
