Solution Overview
Problem
Traditional session authentication methods rely on pseudo-random number generation, which becomes vulnerable to brute force attacks due to increased computing power, allowing attackers to replicate session keys and compromise user sessions.

Engineering Contradiction Analysis
1Reliability
If pseudo-random number generation is used for session key generation, then session authentication can be implemented, but the session key becomes vulnerable to brute force attacks due to increased computing power
Solution Approach 1:
The patent replaces traditional pseudo-random number generation (mechanical/computational system) with quantum random number generation using quantum bits and quantum bases. This substitution introduces fundamental quantum uncertainty that cannot be overcome by increased computing power, thereby resolving the vulnerability to brute force attacks while maintaining session authentication functionality
Solution Approach 2:
The patent changes the fundamental parameter of randomness generation from computational pseudo-randomness to quantum physical randomness. By using quantum bits encoded in different quantum bases (e.g., polarization states), the system generates truly random session keys whose unpredictability is based on quantum mechanics rather than computational complexity, thus eliminating brute force attack vectors
2Productivity
If traditional pseudo-random number generation methods are used, then session IDs can be generated, but patterns in the generation method allow attackers to replicate session keys
Solution Approach 1:
The patent replaces pattern-based pseudo-random generation with quantum mechanical random generation. The quantum measurement process inherently produces unpredictable outcomes based on quantum superposition and collapse, eliminating any deterministic patterns that attackers could exploit while maintaining efficient session ID generation
Solution Approach 2:
The patent performs preliminary quantum key distribution and session key generation before actual communication occurs. By establishing the session key through quantum measurement in advance, the system ensures that the key is generated with true randomness before any communication takes place, preventing attackers from predicting or replicating the key
