Abstract
Secure fast platform hibernation and resumption for computing systems. An embodiment of an apparatus includes a processor to operate according to an operating system, the processor to transition the apparatus to a first reduced power state in response to a request, the transition to the first reduced power state including the processor to store context data for the apparatus in a volatile system memory, and logic to transition the apparatus to a second reduced power state, the logic to write the context data from the volatile system memory to a nonvolatile memory for the transition to the second reduced power state, wherein the logic is to implement one or more security measures for the writing of the context data into the nonvolatile memory.
