SECURE BOOT PROCEDURE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18237247 titled 'SECURE BOOT PROCEDURE
Simplified Explanation
The abstract describes a method for providing protection for a secure boot procedure by halting an open sub-system during the verification of boot firmware, and then allowing the open sub-system to resume the boot procedure once the firmware is verified.
- Verification of boot firmware is performed to ensure its authenticity and integrity.
- During firmware verification, the open sub-system is halted to prevent it from executing the boot procedure.
- The open sub-system can only resume the boot procedure after the firmware is successfully verified.
- The open sub-system remains inactive even after verification until it is placed into the resume state again.
Potential Applications
- Secure boot procedures in computer systems
- Protection against unauthorized firmware modifications
Problems Solved
- Preventing unauthorized access during the boot process
- Ensuring the integrity of the boot firmware
Benefits
- Enhanced security for boot procedures
- Protection against malicious attacks on firmware
Original Abstract Submitted
Protection for a secure boot procedure can be provided in addition to cryptographic verification of boot firmware associated with the boot procedure. While the boot firmware is being verified, an open sub-system can be placed into a halt state, during which the open sub-system is prevented from performing the boot procedure. The open sub-system can be subsequently placed into a resume state to further perform the boot procedure when the boot firmware is verified. The open sub-system is still prevented from performing the boot procedure even if the boot firmware is verified unless the open sub-system is placed into the resume state again.
