ABSTRACT:
A processing system may include a processing unit and nonvolatile storage responsive to the processing unit. The nonvolatile storage may include a candidate boot code module and an authentication code module. The processing unit may be configured to execute code from the authentication code module before executing code from the candidate boot code module. The authentication code module may have instructions which, when executed by the processing unit, cause the processing unit to read a processor identifier from the processing unit and determine whether the processor belongs to a predetermined set of processors associated with a specific vendor, based at least in part on the identifier, before executing any instructions from the candidate boot code module. The processing system may also test authenticity of the candidate boot code module before executing any instructions from the candidate boot code module. Other embodiments are described and claimed.
