Abstract
A programmable processor calculates a hash value of a memory region, then monitors program operation to detect a security monitoring system initialization. The hash value is added to extend a security measurement sequence if the security monitoring system initialization clears a security state. Processors that implement similar methods, and systems using such processors, are also described and claimed.
