PROBLEM TO BE SOLVED: To detect fraudulence such as exchange with a fraudulent board and malfunction, and to reduce loads in a peripheral part. SOLUTION: A main control unit 10 of the game machine 1 includes a means 13 for generating an individual examination value by dividing prescribed data and carrying out the semigroup operation, and a means 14 for generating a synchronous code by using packet information selected based on a divided number and generating a relative time code and a motion examination value by using timing information. The respective examination values are added to data signals to be transmitted to an intermediate part 20. The intermediate part 20 includes an intermediate authentication means 22 for collating the correlations of the packet information included in the received motion examination value with an expected value and checking whether the relative time code increases in time series. The result of collation and the individual examination value are added to the data signals to be transmitted to the peripheral part 30. The peripheral part 30 carries out the individual authentication of the main control unit 10 by subjecting the received individual examination value to connection processing, and includes a motion authentication means 32 for authenticating the motion of the main control unit 10 based on the matching between the result of collation by the intermediate part 20 and the expected value.
