GAME MACHINE, AUTHENTICATION METHOD, AND AUTHENTICATION PROGRAM

摘要

PROBLEM TO BE SOLVED: To detect fraudulence such as exchanging a main control board carrying a regular main control board with a false main control board and to reduce a processing load on a CPU constituting a periphery part.SOLUTION: The game machine includes a main control unit 21 to output control signals including control command data and authentication data to an authentication unit 202, an authentication unit 202 to authenticate a main control unit 201, and a periphery part 203 to carry out prescribed processing based on control command data. The authentication unit 202 authenticates the main control unit 201 based on authentication data and supplies authentication results and control command data to the periphery part 203. The periphery part 203 carries out processing according to authentication results.
