Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The advent of quantum computing poses a significant threat to secure data transmission between quantum-equipped and non-quantum-equipped devices, as quantum-equipped devices can break non-quantum encryption schemes, rendering existing communication methods vulnerable and causing dropped or discarded data, extended processing times, and potential data exposure.
Innovation Solution
A quantum network gateway (QNG) is introduced into the communication network to facilitate secure communications between non-quantum-equipped and quantum-equipped devices, using quantum-resistant encryption techniques, authentication methods, and quantum-based encryption/decryption to establish a quantum-secured communication tunnel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If quantum-equipped devices use quantum computing to break encryption, then security of data transmission is compromised, but this creates vulnerability to attacks and data exposure
Solution Approach 1:
The patent converts the harmful capability of quantum computers to break encryption into a beneficial security mechanism by using quantum key distribution (QKD) and quantum random number generation. The quantum system's inherent properties (superposition, entanglement, no-cloning theorem) are used to create encryption keys that are fundamentally secure against quantum attacks, turning the quantum threat into a quantum solution for security.
Solution Approach 2:
The patent changes the cryptographic parameters from classical encryption schemes to quantum-resistant schemes. This includes using quantum key distribution protocols (BB84, E91) that rely on quantum mechanical principles rather than computational complexity, and implementing post-quantum cryptographic algorithms that are designed to resist quantum computing attacks.
2Reliability
If quantum-resistant encryption techniques are implemented, then security against quantum attacks is improved, but device complexity increases
Solution Approach 1:
The patent introduces a quantum network gateway as an intermediary component that bridges classical and quantum communication infrastructures. This gateway handles the complex quantum operations (qubit generation, transmission, measurement) and presents a simplified interface to end devices, thereby reducing the complexity burden on individual devices while maintaining quantum security.
Solution Approach 2:
The patent segments the quantum communication system into distinct functional modules: quantum key distribution module, quantum random number generation module, quantum authentication module, and classical communication module. This modular segmentation allows each component to be optimized independently and simplifies the overall system architecture and deployment.
3Reliability
If authentication and encryption processes are enhanced for quantum security, then data protection is improved, but processing time increases
Solution Approach 1:
The patent implements preliminary quantum key distribution and authentication processes before actual data transmission. Quantum keys are generated and shared in advance through QKD protocols, and device authentication is performed beforehand using quantum-secured channels. This preliminary action ensures that when data needs to be transmitted, the secure cryptographic material is already in place, reducing real-time processing delays.

AI summary
A quantum communication system for enabling secured communications between non-quantum equipped and quantum equipped devices comprises a non-quantum equipped network device configured to transmit a connection request, a quantum authentication server configured to verify a connection between the non-quantum equipped network device and a quantum network gateway, the quantum network gateway enabling communications between the non-quantum equipped network device and the quantum authentication server. The quantum network gateway includes at least one quantum processor, and a quantum application, which when executed by the quantum processor, cause the quantum application to receive, from the non-quantum equipped network device, a request to communicate with an application server, generate a quantum token, transmit the quantum token to the quantum authentication server for authentication of the communication request, and set up, a communication tunnel between the quantum network gateway and the application server for communicating on behalf of the non-quantum equipped network device.
