BIOS MODULE PROVISIONING SEQUENCE VERIFICATION SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18296720 titled 'BIOS MODULE PROVISIONING SEQUENCE VERIFICATION SYSTEM
The abstract describes a system for verifying a BIOS module provisioning sequence using a BIOS subsystem, TPM, and BIOS storage system.
- The BIOS subsystem provides BIOS modules in a provisioning sequence using firmware volumes.
- For each BIOS module provided, the system retrieves a module identifier and updates provisioning sequence information.
- After provisioning, the BIOS subsystem sends the sequence information to the TPM for verification.
Potential Applications: - Secure boot processes in computer systems - Ensuring the integrity of BIOS modules during provisioning
Problems Solved: - Preventing unauthorized changes to BIOS modules - Enhancing system security by verifying the provisioning sequence
Benefits: - Improved system security and integrity - Protection against malicious firmware modifications
Commercial Applications: Title: Secure BIOS Module Provisioning System for Enhanced System Security This technology can be used in industries where data security is critical, such as finance, healthcare, and government sectors. It can also be implemented in servers, workstations, and other computing devices to safeguard against unauthorized firmware changes.
Prior Art: Researchers can explore existing patents related to BIOS security, TPM integration, and firmware verification to understand the evolution of this technology.
Frequently Updated Research: Researchers in the field of cybersecurity and system integrity may conduct studies on the effectiveness of BIOS module provisioning verification systems in preventing cyber threats.
Questions about BIOS Module Provisioning Sequence Verification: 1. How does the system ensure the authenticity of the BIOS modules during the provisioning sequence? The system retrieves a module identifier for each BIOS module and updates provisioning sequence information to verify the authenticity of the modules.
2. What role does the TPM play in the verification process? The TPM receives the BIOS module provisioning sequence information and compares it to verification information to ensure the integrity of the provisioning sequence.
Original Abstract Submitted
A BIOS module provisioning sequence verification system includes a BIOS subsystem coupled to a TPM and a BIOS storage system including a plurality of firmware volumes. The BIOS subsystem provides a plurality of BIOS modules in a BIOS module provisioning sequence using the plurality of firmware volumes and, for each of the plurality of BIOS modules when that BIOS module is provided during the BIOS module provisioning sequence: retrieves a BIOS module identifier associated with that BIOS module, and updates BIOS module provisioning sequence information using that BIOS module identifier. Following the provisioning of the BIOS modules in the BIOS module provisioning sequence, the BIOS subsystem provides the BIOS module provisioning sequence information to the TPM, with the BIOS module provisioning sequence information configured to be compared to BIOS module provisioning sequence verification information to verify the BIOS module provisioning sequence.
