摘要

PROBLEM TO BE SOLVED: To detect fraudulent actions by the exchange of a proper main control board of a game machine and a fraudulent main control board or the like and malfunctions of the game machine, and to reduce processing loads of the CPU of a peripheral part. SOLUTION: The main control part 10 includes an inspection value generation means 13 for generating a plurality of inspection values by performing a binomial operation using data obtained by dividing predetermined data stored in a data storage means 11 are divided, and an addition means 14 for adding the inspection values to a control command selected beforehand, transmitting it to the post-stage part 20 through a peripheral part 30, and selecting a kind of a specified control command to add the inspection value when performing authentication processing next time on the basis of the number of divided data. The post-stage part 20 includes an authentication means 22 for authenticating the main control part 10 on the basis of whether or not an operation value stored in an operation value storage means 21 storing operation values obtained by performing the binomial operation using the predetermined data stored in the data storage means 11 and the operation result of performing the binomial operation using the plurality of inspection values added to the specified control command match.
