Abstract: Apparatus, systems, and methods may operate to receive operational power from a primary power supply at a processor housed within a wagering game machine, where the processor is operable to present a wagering game. Further activities may include determining that the wagering game machine is currently in a hibernation state, authenticating at least one hibernation file, and resuming operation of the wagering game machine to a base operation state defined by the at least one hibernation file. Additional apparatus, systems, and methods are disclosed.

Abstract: 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.
