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 power source on-command for designating the application or the initialization of the power source and control data, the first authentication data for attesting own authenticity and 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 processing based on the power source on-command and outputs the first authentication data. The peripheral part 3a determines whether the main control part 2a is authentic or not, based on the second authentication data to be generated and outputted by an intermediate part 3b and makes a notification to the effects if it is determined not to be authentic. The intermediate part generates an intermediate data for the determination on the authenticity of the main control part to reduce the burden on the peripheral part as compared with the case of making the peripheral part carry out all of the processing for the authentication, thereby enabling the determination on whether the main control part is authentic or not with a larger strength of security than ever.
