GAME MACHINE, MAIN CONTROLLER, MAIN CONTROL BOARD, POST-STAGE PART, PERIPHERAL BOARD, AUTHENTICATION METHOD, AND AUTHENTICATION PROGRAM

摘要

PROBLEM TO BE SOLVED: To detect a fraudulent act or false operation due to the exchange of a main control board of a game machine for a fraudulent board and to reduce processing load on a peripheral part.

SOLUTION: The main controller 10 of the game machine 1 includes an individual test value generator 12 for generating a first or second individual test value when a control command to be output is a first or second control command, adds the first individual test value to the first control command or the second individual test value to the second control command, and transmits it to a post-stage part 20 or the peripheral part 30. The post-stage part 20 includes a first individual authentication part 24 for collating the added first individual test value with a first arithmetic value held in advance when receiving the first control command to authenticate the main controller 10 and transmits the result of authentication to the peripheral part 30. The peripheral part 30 includes a second individual authentication part for collating the added second individual test value with a second arithmetic value held in advance when receiving the second control command or authenticating the main controller 10 on the basis of the result of authentication received from the post-stage part 20.
