Trusted boot verification for information handling systems
The patent US12074980B2 outlines a computing environment designed to ensure the trusted state of information handling systems through a series of cryptographic and verification processes. The primary components include a first information handling system that receives a chained cryptographic hash value from a trusted platform module (TPM) of a second information handling system, along with patch identities for updated firmware across various components. The system also processes an event log generated by the TPM, retrieves layered endorsements linked to the patch identities, and compares the received hash value and event information against stored signatures to ascertain whether the second information handling system has booted into a trusted state.
Additionally, the patent describes methods for remediation if the second information handling system fails to boot into a trusted state. This includes reinstalling updated firmware as necessary. The layered endorsements, which contain signatures of reference integrity measurements, are crucial for validating the integrity of the firmware. The patent also specifies that the second information handling system may comprise various components, including baseboard management controllers and expansion cards, which can encompass a range of functionalities from graphics processing to artificial intelligence. Overall, the patent emphasizes a structured approach to maintaining system integrity through cryptographic validation and remediation processes.
