摘要

PROBLEM TO BE SOLVED: To detect fraudulence such as exchange with a fraudulent board and malfunction, and to reduce processing 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 motion examination value by generating a synchronous code using packet information selected based on the divided number and generating a relative time code using timing information. The respective examination values are added to data signals to be transmitted to a latter part 20 or to the peripheral part 30. The latter part 20 includes an intermediate authentication means 22 for collating the correlation 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 is 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 an authentication means 32 for authenticating the motion of the main control par 10 based on the matching between the result of collation by the latter part 20 and the expected value.
