ABSTRACT:
Methods and apparatus for implementing a secure resume are disclosed. In an example, a method of securely resuming operation of a processor from a low power state to an active state includes detecting a resume event, calculating a metric of information stored in memory locations, wherein the information is used by the processor to resume operation from the low power state to the active state and comparing the calculated metric to a stored metric and resuming operation from the low power state to the active state if the calculated metric and the stored metric match.
