Engineering Contradiction Analysis
1Reliability
If classical key distribution algorithms are used, then computational simplicity is maintained, but security vulnerability increases due to advancements in computing power and quantum computers
Solution Approach 1:
The patent replaces traditional computational cryptographic systems with a physics-based timing system. Instead of relying on mathematical one-way functions that are vulnerable to computational advances, the system uses physical timer circuits with inherent timing characteristics that are difficult to replicate or predict, substituting computational security with physical security.
Solution Approach 2:
The timer circuits are designed to be self-powered using energy harvesting techniques, eliminating the need for external power sources or batteries. This self-service capability ensures continuous operation and maintains timing accuracy without requiring manual intervention for power management, while the physical timing characteristics provide inherent security.
2Reliability
If quantum key distribution is used, then security guarantees are improved, but portability and ease of use deteriorate due to dedicated communication links and calibration requirements
Solution Approach 1:
The patent creates a classical system that copies or emulates the security properties of quantum key distribution using conventional hardware. The synchronized timer circuits generate timing patterns that serve as cryptographic keys, replicating the security functionality of quantum systems without requiring quantum hardware, specialized communication links, or complex calibration procedures.
Solution Approach 2:
The timer-based authentication system is designed to be universally applicable across different platforms and communication channels. Unlike quantum systems that require dedicated infrastructure, this system can operate on standard IoT devices and use existing communication infrastructure, making it both secure and portable.
3Device complexity
If static identifiers are used for authentication, then implementation simplicity is maintained, but security deteriorates due to vulnerability to theft, counterfeiting, and replay attacks
Solution Approach 1:
The patent transitions from static authentication identifiers to dynamic timing-based credentials. The timer circuits continuously generate changing timing patterns that serve as authentication credentials, making them dynamic and time-varying. This dynamism prevents replay attacks and counterfeiting while maintaining relatively simple implementation through hardware timer circuits.
