Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pseudo-random number generation is used to generate session keys, then session authentication can be implemented, but the session keys become susceptible to brute force attacks as computing power increases
Solution Approach 1:
The patent replaces the mechanical/computational pseudo-random number generation system with a quantum mechanical system. Quantum key distribution uses the principles of quantum mechanics (superposition, entanglement, and measurement collapse) to generate truly random session keys. The quantum system fundamentally differs from classical computational systems, making the generated keys unpredictable and resistant to brute force attacks, as the security is based on physical laws rather than computational complexity.
Solution Approach 2:
The patent changes the fundamental parameter of randomness generation from algorithmic pseudo-randomness to quantum mechanical true randomness. By utilizing quantum states and their inherent probabilistic nature, the system generates session keys with entropy that cannot be reproduced or predicted, even with unlimited computing power. This parameter change transforms the security model from computational hardness to physical law-based security.
2Productivity
If traditional random number generation methods are used, then session keys can be generated efficiently, but the patterns in generation can be replicated by attackers with sufficient computing resources
Solution Approach 1:
The patent replaces the algorithmic random number generation mechanism with a quantum mechanical mechanism. Quantum key distribution protocols (such as BB84) use quantum states to generate random bits that are fundamentally unpredictable. The quantum system maintains efficiency through optimized quantum operations and classical post-processing, while achieving true unpredictability based on quantum measurement outcomes that cannot be determined until measured.
Solution Approach 2:
The patent transitions from the classical computational dimension to the quantum mechanical dimension. By utilizing quantum superposition and entanglement, the system generates randomness that exists in a higher-dimensional quantum state space. This dimensional transition allows for truly random key generation that cannot be replicated by classical computational methods, as the quantum states encode information in ways that are fundamentally inaccessible to classical systems.
