Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The modular arrangement of security control modules (SCMs) and host processor modules (HPMs) in computing environments is vulnerable to identity manipulation attacks, where unauthorized access occurs due to swapping SCMs between secure and unsecure areas, compromising system integrity.

Innovation Solution

Implement a management system with an SCM validation engine that performs multiple validations, including cryptographic device identity checks and manifest certificate verifications, to ensure authorized connections between SCMs and HPMs, using DevID and platform certificates to detect unauthorized swaps.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If SCMs are made modular and interchangeable between secure and unsecure areas, then adaptability and ease of operation are improved, but security vulnerability increases due to identity manipulation attacks

Engineering Contradiction:

Improveinterchangeability of SCMsVSAvoididentity manipulation attack vulnerability

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The system performs preliminary validation actions before allowing SCM operations. The validation engine checks cryptographic device identities and manifest certificates beforehand to ensure the SCM is authorized for its intended operational area, preventing unauthorized swaps before they can compromise security

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The validation engine continuously monitors SCM identities and operational contexts, providing feedback when mismatches are detected. This feedback mechanism enables real-time detection of unauthorized SCM swaps and triggers appropriate security responses

Inventive Principle:

Principle #23Feedback

2Reliability

If multiple validation checks are performed on SCMs, then security and reliability are improved, but device complexity increases

Engineering Contradiction:

Improvesystem security integrityVSAvoidvalidation system complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The validation system is segmented into distinct functional components: cryptographic device identity validation, manifest certificate validation, and operational context verification. Each segment handles a specific aspect of validation, making the overall complex system manageable and maintainable through modular design

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The validation engine acts as an intermediary between the SCM and the operational system. It mediates all SCM interactions by performing necessary validations without requiring the rest of the system to understand or implement complex validation logic, thereby isolating complexity to a single component

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

In some examples, a system can validate a security module connected to a processor module using a cryptographic device identity of the security module, and perform a manifest certificate check based on a manifest certificate containing information representing a security processor in the security module.
