Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If both traditional channel and quantum channel are used for key derivation and authentication, then the completeness of cryptographic processes is improved, but the system is exposed to cyber risks such as Replay Attack or DDoS Attack
Solution Approach 1:
The patent extracts the authentication and key derivation processes from the traditional channel and relocates them entirely to the quantum channel. By removing the traditional channel's involvement in these critical security functions, the system eliminates the security vulnerabilities associated with traditional communication while maintaining complete cryptographic processes through quantum-only operations.
Solution Approach 2:
The patent introduces quantum states as an intermediary carrier for both key derivation and authentication. Instead of using separate channels for different cryptographic functions, the quantum channel serves as a unified intermediary that handles all security-critical operations, thereby eliminating the need for traditional channel participation and its associated risks.
2Object-affected harmful factors
If only quantum channel is used for key derivation and authentication, then the security against cyber attacks is improved, but signal-decay issues lead to transmission instability
Solution Approach 1:
The patent performs preliminary error detection and correction operations on quantum states before they are fully utilized for key derivation. By preparing and validating quantum states in advance, the system compensates for potential signal decay effects, ensuring transmission stability while maintaining security through quantum-only operations.
Solution Approach 2:
The patent implements feedback mechanisms where measurement results from quantum states are used to adjust and optimize subsequent quantum operations. This feedback loop allows the system to compensate for signal decay effects in real-time, maintaining transmission stability while operating exclusively through the quantum channel.
3Manufacturing precision
If filter module with multiple filtering units is used, then the quality of quantum keys is improved, but the device complexity increases
Solution Approach 1:
The patent merges multiple filtering functions into a unified filter module structure. By combining Bell measurement, maximum entanglement filtering, entropy calculation, and DOF filtering into an integrated module, the system achieves high-quality quantum key generation while reducing the operational complexity compared to separate independent filtering systems.
Solution Approach 2:
The patent segments the filtering process into distinct functional units that operate in sequence. By dividing the complex filtering task into manageable segments (Bell measurement unit, entanglement filtering unit, entropy calculation unit, DOF filtering unit), the system maintains high key quality while making the overall device more manageable and implementable.

AI summary
A system for use in quantum encryption, decryption, and encoding, comprises a photon production sub-system, a transmission channel sub-system, and a data encoding sub-system. The transmission channel sub-system makes use of the combination of quantum state vectors derived from the photon production sub-system for optical communication with quantum key. The data encoding sub-system includes a plurality of dynamic data encoding modules, and at least one of these modules performs to express the quantum key with bases in an individual Hilbert Space, and divides the transmitting data into segments for data encoding with the individual space bases. In addition to the use in data encoding, the sub-system can also improve the signal-decays and the eavesdropping issue within the quantum channel via implementation of the Laplace Transformation unit and the Quantum Fourier Transformation unit.
