Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional data security approaches are used in cloud computing, then ease of operation is maintained, but security reliability is insufficient against quantum computing threats
Solution Approach 1:
The system segments security functions into distinct modules: quantum key distribution for key generation, trusted computing modules for key storage and protection, and classical communication for data transmission. This segmentation allows each component to specialize in specific security tasks, improving overall reliability while managing complexity through modular architecture
Solution Approach 2:
The patent introduces quantum key distribution as an intermediary mechanism between communicating parties, enabling secure key exchange without direct exposure of cryptographic keys. The trusted computing module acts as an intermediary that verifies platform integrity and protects sensitive operations, thereby enhancing security reliability without requiring complete system redesign
2Reliability
If quantum key distribution and trusted computing are implemented, then security against quantum threats is improved, but device complexity increases
Solution Approach 1:
The system dynamically negotiates quantum keys for each communication session, allowing security parameters to adapt to current threats and requirements. The trusted computing module dynamically verifies platform integrity and adjusts security operations based on runtime conditions, providing quantum-level security without static rigid architecture
Solution Approach 2:
The patent replaces classical cryptographic key exchange mechanisms with quantum key distribution, substituting mathematical problem-solving with quantum physical principles. This substitution provides provable security against quantum attacks while the trusted computing module handles the complex key management operations, separating security concerns from application logic
3Reliability
If dynamic monitoring and authentication of user behaviors is implemented, then security detection capability is improved, but processing time increases
Solution Approach 1:
The trusted computing module performs preliminary measurements of platform configuration registers and generates trustworthiness information during system initialization and boot-up. This preliminary action allows authentication to proceed quickly during runtime, as the foundation of trust has already been established without requiring extensive real-time analysis
Solution Approach 2:
The system continuously monitors platform integrity and user behaviors, providing feedback to the trusted computing module. This feedback mechanism enables dynamic adjustment of security operations, allowing the system to maintain high authentication capability while minimizing processing time through intelligent resource allocation based on current security needs

Data Source
AI summary
One embodiment described herein provides a system and method for ensuring data and computation security. During operation, a server receives a key-negotiation request from a client and authenticates the client. In response to the client authenticating the server, the server negotiates, via a quantum-key-distribution process, a secret key shared between the client and the server; and stores the secret key in a trusted-computing module.
