Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing authentication methods based on mathematical algorithms are used, then the authentication process is simple and easy to implement, but the security is vulnerable to quantum computing attacks and mathematical algorithm cracks
Solution Approach 1:
The patent introduces a quantum key distribution network as an intermediary between the user terminal and the authentication server. This intermediary distributes quantum keys that enable secure authentication without requiring the terminal and server to directly share sensitive information, thus enhancing security while maintaining system manageability
Solution Approach 2:
The patent replaces traditional mathematical algorithm-based encryption mechanisms with quantum key distribution mechanisms. By using quantum mechanical principles (quantum entanglement and quantum superposition) instead of mathematical complexity, the system achieves security that is fundamentally resistant to quantum computing attacks
2Reliability
If quantum key distribution network is introduced for high security authentication, then the security resistance against spoofing and deciphering attacks is significantly improved, but the system complexity and implementation difficulty increase
Solution Approach 1:
The quantum key distribution network automatically performs key generation, distribution, and management without requiring manual intervention. The system self-configures the authentication relationships between terminals and servers, reducing implementation complexity despite the advanced quantum technology involved
Solution Approach 2:
The quantum key distribution network is designed to serve multiple authentication scenarios and device types universally. By creating a standardized quantum authentication framework that can handle various authentication needs, the system reduces implementation difficulty through reusability and standardization
