Pre-authorized virtualization engine for dynamic firmware measurement

A virtual BIOS engine may be configured to, during runtime of an operating system, in response to an operating system event for updating firmware, load onto an isolated compute domain of the processor to emulate firmware update processes of a non-transitory computer-readable media with a virtual non-transitory computer-readable media and emulate the firmware update processes of the cryptoprocessor with a virtual cryptoprocessor, extract a firmware payload to the virtual non-transitory computer-readable media, and execute a virtual trust chain to measure the firmware payload in the virtual non-transitory computer-readable media.
