High assurance configuration security processor (HACSP) for computing devices

A High Assurance Configuration Security Processor (HACSP) for a computing device may perform real-time integrity measurements of an actual bitstream run-time performance against what is expected. The HACSP may be self-contained and have a relatively small footprint. The HACSP may be vendor-agnostic, and may be a trusted system application for the computing device. The HACSP may ensure the security of user application bitstream load and update during device configuration, and may implement security mechanisms for independent secure trusted attestation and integrity measurement mechanisms to report and provide reliable evidence about the ?trustworthiness? of the system during user bitstream execution.
