METHODS AND APPARATUSES FOR RECOVERING USAGE OF TRUSTED PLATFORM MODULE
摘要:
Methods and systems to perform platform security in conjunction with hardware-base root of trust logic are presented. In one embodiment, a method includes determining whether a status from an authenticated code module is indicative of an error or not. The method further includes determining whether the hardware-based root of trust logic is enabled based on content in a non-volatile memory location. If the hardware-based root of trust is enabled and the status is indicative of an error, the method further includes writing to the non-volatile memory location to disable hardware-based root of trust logic during a next boot sequence. In one embodiment, a platform initializes and uses the trusted platform module in conjunction with the hardware-based root of trust logic or with a platform-based root of trust logic.
