ABSTRACT:
An apparatus may include a root of trust for measurement (RTM) module coupled to a verified platform security property policy module and a comparison module. The comparison module may operate to prevent transfer of control to an operating system (and/or halt the boot process) if a policy included in the platform security property policy module is violated. A system may include a memory coupled to a processor, a platform security property policy module, and a comparison module. The memory may include an RTM. A method may include beginning execution at an entry point within an RTM, determining that the RTM is trustworthy, determining that a main initialization code associated with a platform is trustworthy and transferring control to the main initialization code, and otherwise, refraining from transferring control to the main initialization code.
