Engineering Contradiction Analysis
1Reliability
If conventional PQC technologies use hyper complicated encryption systems (such as Lattice, Code-based, Supersingular Elliptic Curve Isogency), then quantum attack-resistant operations can be implemented, but device complexity and data traffic increase significantly
Solution Approach 1:
The patent introduces a hybrid key exchange mechanism that acts as an intermediary between legacy cryptographic systems and quantum-resistant requirements. The system combines classical key exchange protocols with quantum key distribution (QKD) techniques, allowing legacy systems to maintain security without complete replacement. This intermediary approach enables gradual transition and maintains compatibility while achieving quantum attack resistance.
Solution Approach 2:
The patent segments the key exchange process into multiple independent stages: legacy key generation, quantum key generation, key combination, and verification. Each stage can be implemented and verified separately, reducing the overall system complexity. The segmentation allows selective implementation of quantum-resistant components without requiring complete system overhaul.
2Reliability
If PQC systems implement handshaking, encryption, and decryption mechanisms, then quantum attack resistance is achieved, but data traffic increases greatly causing replacement issues on existing HTTP web servers
Solution Approach 1:
The patent implements partial quantum resistance by selectively applying quantum key distribution only to critical key exchange operations rather than encrypting all data traffic. This partial action approach provides quantum attack resistance for the most security-sensitive operations while minimizing the increase in data traffic. The system uses classical encryption for bulk data transmission and reserves quantum mechanisms for key establishment.
3Adaptability or versatility
If current symmetric and asymmetric cryptography systems are used, then legacy compatibility is maintained, but vulnerabilities to quantum computing attacks and other security threats cannot be effectively avoided
Solution Approach 1:
The patent merges legacy cryptographic algorithms with quantum key distribution mechanisms into a unified hybrid system. The system combines the advantages of classical cryptography (proven security, legacy compatibility) with quantum cryptography (forward security, quantum attack resistance). The hybrid approach allows simultaneous operation of legacy and quantum-resistant components, achieving both compatibility and enhanced security.
4Ease of operation
If quantum key distribution is operated in a Hilbert space with orthonormal basis, then quantum operations can be performed, but the possibility of brute-force cracking by quantum computing attacks increases
Solution Approach 1:
The patent introduces asymmetric mathematical problems (such as lattice-based problems or code-based problems) into the quantum key exchange protocol. These asymmetric problems provide one-way functions that are easy to compute in one direction but difficult to reverse, even with quantum computing power. The asymmetry creates a mathematical barrier that prevents brute-force attacks while maintaining quantum operational capabilities.

AI summary
A quantum attack-resistant system for processes of cryptography key exchange comprises a linear space computing module, a manifold computing module, and a Banach space computing module. The system implements the technologies of homotopy morphing and key cloaking for facilitating the processes of key exchange to perform quantum attack-resistant operations in a mathematics space which is different from the spaces that generic quantum attacks work on, and then retrieve the original key in a Hilbert space after the processes of key exchange. The system not only avoids quantum attacks on key exchange processes, but also avoids the defects of current PQC solutions, the vulnerability of the main streamed symmetric & asymmetric encryption systems, and the limitation of quantum key operation in a Hilbert space. Both legacy key solution and quantum key solution are provided and implemented without requiring expensive devices.
