BIOS MODULE PROVISIONING SEQUENCE VERIFICATION SYSTEM - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240338452 titled 'BIOS MODULE PROVISIONING SEQUENCE VERIFICATION SYSTEM

The abstract describes a system for verifying a BIOS module provisioning sequence, involving a BIOS subsystem, a TPM, and a BIOS storage system with multiple firmware volumes.

  • The BIOS subsystem provides BIOS modules in a provisioning sequence using the firmware volumes.
  • For each BIOS module provided, the system retrieves a module identifier and updates provisioning sequence information.
  • After all modules are provisioned, the BIOS subsystem sends the provisioning sequence information to the TPM for verification.

Key Features and Innovation:

  • Utilizes a TPM to verify the BIOS module provisioning sequence.
  • Enhances security by ensuring the correct BIOS modules are provisioned in the correct order.
  • Streamlines the BIOS module provisioning process for improved efficiency.

Potential Applications:

  • Computer systems with BIOS modules that require secure provisioning.
  • Devices that rely on BIOS modules for functionality and security.

Problems Solved:

  • Ensures the integrity of the BIOS module provisioning process.
  • Prevents unauthorized or incorrect BIOS modules from being provisioned.

Benefits:

  • Enhanced security for BIOS module provisioning.
  • Improved system reliability and performance.
  • Simplified management of BIOS modules.

Commercial Applications:

  • Secure provisioning of BIOS modules in enterprise servers.
  • Enhanced security features for consumer electronics with BIOS modules.

Questions about BIOS Module Provisioning Sequence Verification: 1. How does the system ensure the correct order of BIOS modules in the provisioning sequence? 2. What are the potential risks if the BIOS module provisioning sequence is not verified correctly?

Frequently Updated Research: Research on advancements in TPM technology for enhanced BIOS security.


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.
