摘要： A system and method for providing a secure boot architecture, in accordance with one embodiment of the present invention, includes a processor having an atomic state machine and a physically protected storage area. The atomic state machine stores a state of the processor in a state save map upon a boot-mode event. The atomic state machine also authenticates an object of a Pre-BIOS Boot Vector Region (PBBVR) in response to the boot-mode event. The PBBVR may be stored in the physically protected storage area. The atomic state machine loads the PBBVR from the physically protected storage area into an overlay memory if the PBBVR is successfully authenticated. The processor executes the PBBVR from the overlay memory if the PBBVR is successfully authenticated. The atomic state machine may also receive a candidate PBBVR upgrade image, authenticate the candidate PBBVR upgrade image, and replace the current PBBVR with a new PBBVR contained in the candidate PBBVR upgrade image if the new PBBVR in the candidate PBBVR upgrade image is authenticated.
摘要翻译：根据本发明的一个实施例的用于提供安全引导架构的系统和方法包括具有原子状态机和物理保护存储区域的处理器。原子状态机在引导模式事件时将处理器的状态存储在状态保存映射中。原子状态机还会响应引导模式事件来鉴别BIOS引导向导区域（PBBVR）的对象。 PBBVR可以存储在物理保护的存储区域中。如果PBBVR成功认证，原子状态机将PBBVR从物理保护的存储区域加载到重叠存储器中。如果PBBVR被成功认证，处理器将从覆盖存储器执行PBBVR。原子状态机还可以接收候选PBBVR升级映像，认证候选PBBVR升级映像，并且如果候选PBBVR升级映像中的新PBBVR被认证，则将当前PBBVR替换为候选PBBVR升级映像中包含的新PBBVR。
