Abstract
A method and apparatus are disclosed for sharing an integrity security module in a dual-environment computing device. The apparatus include an integrity security module, one or more processors, a detection module and a regeneration module. The one or more processors may have access to the integrity security module and may operate in two distinct operating environments of a dual-environment computing device. The detection module may detect, during an initialization sequence, a power state transition of an operating environment of the dual-environment computing device. The regeneration module may regenerate one or more integrity values from a stored integrity metric log in response to detecting the power state transition of the operating environment of the dual-environment computing device.
