PROBLEM TO BE SOLVED: To solve the problem that restriction on design arises when the strength of security is increased in a conventional game machine.SOLUTION: Besides authenticating the connection device of a CPU, from a main control part 2a, a jackpot command for specifying a special prize state and first authentication data for authenticating that it is valid are outputted. A peripheral part 3a inputs the output of the main control part 2a, controls the execution of a performance or the like based on the jackpot command, and outputs the first authentication data. The peripheral part 3a determines whether or not the main control part 2a is valid on the basis of second authentication data which are generated in an intermediate part 3b and outputted. When it is determined that it is not valid, that effect is reported. Since intermediate data for determining whether or not the main control part is valid are generated in the intermediate part, burdens on the peripheral part are reduced compared to the case of executing the entire authentication processing in the peripheral part, the security is made stronger than before, and whether or not the main control part is valid is determined. |
