摘要: A secure smart card or other modular memory device is plugged into (or otherwise connected to) a port of game controller board internal to gaming machine, where it not accessible player. The programmed detect an encrypted “challenge” message from the host CPU and output “response.” If determines that response has expected properties, then verifies program (an application program) also authentic, can be played. challenge/request exchange may performed periodically ensure still installed. improper, will issue halt command play game.
