Platform Certificate Attestation With Embedded Component Roots
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Managing and verifying the certificates for numerous components on a platform is complex and time-consuming, leading to inefficiencies and increased risk of errors, especially when components are replaced, removed, or added during the platform's lifecycle, and maintaining up-to-date root certificates adds another layer of complexity.
Innovation Solution
Embedding root certificates for components into a platform certificate, consolidating management into a single platform certificate to streamline verification processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If individual root certificates are managed separately for each component, then verification accuracy is maintained, but verification complexity and time increase significantly
Solution Approach 1:
The patent merges multiple individual component certificates and their associated root certificates into a single platform certificate. This consolidation allows verifiers to validate entire platforms with one certificate rather than managing separate verification processes for each component, directly reducing verification complexity while maintaining security through the unified certificate structure
2Measurement precision
If multiple individual component certificates are verified separately, then component identity verification is accurate, but verification time increases
Solution Approach 1:
By combining multiple component certificates into a single platform certificate that contains embedded root certificates for all components, the system enables parallel verification of entire platforms in one operation rather than sequential verification of individual components, significantly reducing total verification time while maintaining accuracy
3Reliability
If root certificates are updated for each component change, then certificate accuracy is maintained, but management complexity increases
Solution Approach 1:
The unified platform certificate embeds all component root certificates in a single structure, allowing centralized management and updates. When components change, the system can update the platform certificate in one operation rather than managing multiple separate certificate files, reducing management complexity while maintaining reliability through the consolidated approach
4Reliability
If verifiers acquire root certificates from external trusted sources, then verification reliability is ensured, but verification fails in air-gapped networks
Solution Approach 1:
The platform certificate embeds component root certificates within its structure, creating a nested certificate hierarchy where trusted root certificates are contained inside the platform certificate. This allows verifiers to obtain all necessary trusted certificates from a single local source without needing external connections, enabling verification in air-gapped environments while maintaining reliability

AI summary
Systems and methods for streamlined platform attestation are described. In an illustrative, non-limiting embodiment, an Information Handling System (IHS) may include a processor and a memory coupled to the processor. The memory may have program instructions stored thereon that, upon execution, cause the IHS to: read root certificates for a plurality of components of the IHS; and embed the root certificates for the plurality of components into a platform certificate.
