Hardware Functionality Scan for Secure Session Key Generation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional computer security systems, particularly in PCs, are vulnerable to unauthorized access due to their open architecture, which allows easy tampering and access points for hackers, unlike closed systems like consumer electronics devices, where hardware components are harder to modify, making them more secure.
Innovation Solution
Implementing a hardware functionality scan (HFS) system and a unique session key system in PCs to verify the authenticity of hardware components and establish a secure encryption key, similar to consumer electronics devices, by using complex queries and one-way functions to generate and manage unique session keys independently within the CPU and graphics/audio codec devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an open architecture PC system is used, then hardware components can be easily replaced and the system is more adaptable, but security is compromised due to multiple access points for unauthorized users
Solution Approach 1:
The system divides security verification into separate functional modules: hardware functionality scan module, unique session key generation module, and content decryption module. Each hardware component (CPU, graphics device, audio device) performs specific security functions independently, allowing the system to maintain open hardware replaceability while ensuring security through modular verification processes
Solution Approach 2:
The patent introduces a hardware functionality scan as an intermediary verification mechanism between the open hardware architecture and the security requirements. This scan acts as a mediator that authenticates hardware components without restricting their replaceability, enabling the system to accept various hardware components while maintaining security through standardized verification protocols
2Ease of operation
If conventional security systems are used in PCs, then the system remains open and accessible, but unauthorized access and content interception become more likely
Solution Approach 1:
The system performs preliminary security actions by conducting hardware functionality scans and generating unique session keys before content decryption occurs. This preliminary verification ensures that only authenticated hardware components can access protected content, preventing unauthorized access while maintaining system openness for legitimate operations
Solution Approach 2:
Each hardware component (CPU, graphics device, audio device) performs self-verification through the hardware functionality scan and generates its own unique session key independently. This self-service approach allows the system to maintain ease of operation with accessible hardware while automatically enforcing security measures without requiring external intervention or restricting user access
3Reliability
If hardware components are made secure like consumer electronics, then unauthorized access is prevented, but the open architecture and ease of hardware replacement are lost
Solution Approach 1:
The patent implements a universal hardware functionality scan that can verify multiple types of hardware components (CPU, graphics devices, audio devices) through a single standardized process. This universal verification mechanism enables secure hardware replacement across different component types while maintaining the open architecture's adaptability, as any compliant hardware can be verified and integrated
