摘要

PROBLEM TO BE SOLVED: To detect a fraudulent action such as the exchange of a main control board of a game machine with an improper board and malfunction associated with that, and to reduce the processing load of a periphery part.;SOLUTION: A main control part 10 of a game machine 1 includes: an individual inspection value generation means 13 for generating an individual inspection value by dividing prescribed data and executing semigroup computing; and an operation inspection value generation means 14 for generating an operation inspection value by generating a cord synchronously with the use of packet information selected on the basis of the number of divisions. Each inspection value is added to a data signal and is transmitted to an intermediate part 20. The intermediate part 20 includes an intermediate authentication means 22 for collating a correlative relationship of the packet information included in the received operation inspection value with an expected value, adds a collated result and the individual inspection value to the data signal, and transmits it to a periphery part 30. The periphery part 30 includes an authentication means 32 for executing individual authentication of the main control part 10 by applying connection processing to the received individual inspection value, and for executing operation authentication of the main control part 10 based on whether or not the collated result in the intermediate part 20 corresponds to the expected value.;COPYRIGHT: (C)2011,JPO&INPIT
