Abstract:
In one embodiment, the present invention includes a method for obtaining a pre-boot authentication (PBA) image from a non-volatile storage that is configured with full disk encryption (FDE), and storing the PBA image in a memory. Then a callback protocol can be performed between a loader executing on an engine of a chipset and an integrity checker of a third party that provided the PBA image to confirm integrity of the PBA image, the PBA image is executed if the integrity is confirmed, and otherwise it is deleted. Other embodiments are described and claimed.
