SMI FOR ELECTRONIC GAMING MACHINE SECURITY AND STABILITY

摘要

A system and method for providing security services to an electronic gaming machine (EGM) utilizes system management interrupts (SMIs) triggered by security events to invoke execution by the EGM processor of one or more SMI handlers configured to provide a security service. Security events include the opening of an access panel on the EGM, an AC power loss to the EGM, a request for security attestation, a request for a secure encryption key, and other events requiring a secure operation to be carried out.

主权项

1. An electronic gaming machine (EGM) comprising:
a processor for executing tasks within the EGM, the processor being configured to provide a system management mode (SMM) triggered via a system management interrupt (SMI); a nonvolatile memory having therein a basic input/output system (BIOS), the BIOS including one or more SMI handlers, the one or more SMI handlers being configured to provide a security service to the EGM; and a volatile memory wherein the BIOS is loaded upon start-up of the processor and wherein an operating system (OS) kernel memory data is stored.
