Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The industry lacks an effective approach to ensure the security of information handling system hardware during transit from the manufacturer to the intended end user, as existing security measures are inadequate in detecting tampering with hardware components.

Innovation Solution

An information handling system with a BIOS that stores a hardware profile during creation and verifies it during boot, issuing an alert if any discrepancies are found, thereby detecting potential tampering by comparing the new hardware profile to the stored profile.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If hardware components are replaced during transit to mimic original components, then the system appears secure, but malicious operations can be performed undetected

Engineering Contradiction:

Improvehardware securityVSAvoidundetected tampering

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent applies preliminary action by creating a hardware profile during manufacturing that captures unique identifying information of hardware components before they can be tampered with. This profile is stored securely and used for later verification during system boot, enabling detection of any hardware replacements or modifications that occur during transit or deployment.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent implements feedback by continuously verifying hardware integrity through comparison of the stored hardware profile with the current hardware configuration during each system boot. This creates a closed-loop security mechanism where any deviation from the original hardware state is detected and can trigger security responses, providing ongoing verification rather than a one-time check.

Inventive Principle:

Principle #23Feedback

2Reliability

If traditional security measures are used, then software integrity can be verified, but hardware tampering cannot be detected

Engineering Contradiction:

Improvesoftware securityVSAvoidhardware verification capability

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent applies universality by creating a hardware profile verification mechanism that works across different hardware platforms and component types. The solution is not limited to specific hardware architectures but can verify integrity of various information handling resources including processors, memory, storage devices, and network interfaces, making it broadly applicable to different system configurations.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent uses the hardware profile as an intermediary that bridges the gap between hardware components and security verification. Instead of directly verifying hardware integrity through complex hardware-level checks, the profile serves as a portable, verifiable representation of the hardware state that can be compared against the current system configuration, simplifying the verification process while maintaining security.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Reliability

If hardware verification is implemented, then tampering can be detected, but additional verification steps are required during boot

Engineering Contradiction:

Improvehardware integrity detectionVSAvoidboot verification time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent applies partial action by implementing hardware verification that can be selectively enabled or disabled through a boot mode parameter. Users can choose to perform full hardware profile verification during boot when security is a priority, or bypass this step when speed is more important and hardware tampering is not a concern. This allows the system to balance security requirements against boot time requirements based on the specific operational context.

Inventive Principle:

Principle #16Partial or excessive action

AI summary

A method comprising may include storing, in a BIOS comprising a program of instructions executable by the processor and configured to cause the processor to initialize one or more information handling resources of an information handling system, a hardware profile of the information handling system, the hardware profile comprising identifying information of one or more information handling resources of the information handling system recorded during creation of the hardware profile. The method may also include, during a boot of the information handling system in a hardware verification mode, creating a new hardware profile comprising identifying information of the one or more information handling resources, comparing the new hardware profile to the hardware profile stored in the BIOS, and if the new hardware profile differs from the hardware profile stored in the BIOS, issuing an alert indicating potential tampering with hardware of the information handling system after creation of the profile.
