1Reliability
If existing encryption algorithms are used, then current security systems can operate, but they are vulnerable to non-classical computations
Solution Approach 1:
The system dynamically switches between classical and post-quantum cryptographic algorithms based on the computational capabilities of the communication counterpart. This allows the security system to adapt its cryptographic strength to match the threat model, using post-quantum algorithms when facing potentially quantum-capable adversaries while maintaining compatibility with classical systems when quantum threats are not present.
Solution Approach 2:
The patent changes the cryptographic parameter set by introducing post-quantum cryptographic algorithms as an alternative to classical algorithms. This parameter change enables the system to resist non-classical computations while maintaining the same functional encryption and decryption operations, effectively upgrading security without changing the fundamental system architecture.
2Reliability
If post-quantum cryptographic algorithms are implemented, then security resilience against non-classical computations is improved, but system complexity increases
Solution Approach 1:
The system introduces a cryptographic capability negotiation mechanism that acts as an intermediary between the sender and receiver. This intermediary automatically selects the appropriate cryptographic algorithm (classical or post-quantum) based on mutual capability assessment, thereby managing the complexity of supporting multiple algorithms without requiring manual configuration or user intervention.
Solution Approach 2:
The cryptographic system is segmented into separate classical and post-quantum algorithm components, each handled independently. This modular segmentation allows the system to implement post-quantum cryptography without completely redesigning the existing classical cryptographic infrastructure, thereby managing complexity through incremental adoption and independent component management.
3Reliability
If cryptographic algorithms are rotated or substituted, then long-term security is improved, but operational overhead increases
Solution Approach 1:
The system performs preliminary capability assessment and algorithm selection during the initial connection establishment phase. By determining whether post-quantum or classical cryptography will be used before actual data transmission begins, the system avoids the need for mid-transmission algorithm switching, thereby reducing operational overhead and time loss while still enabling long-term security through post-quantum algorithms.
