Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional encryption techniques used in datacenter environments are vulnerable to quantum computing attacks, as they are non-quantum resilient, and current Quantum Key Distribution (QKD) solutions provide low secure key rates and are not economically viable for widespread deployment in hyperscale datacenters.
Innovation Solution
A quantum hybrid cryptography scheme is implemented using a hybrid quantum-classical transmitter and receiver system, which embeds qubits into classical bitstreams for transmission over optical communication channels, allowing for detection of eavesdropping and providing improved security through quantum-resistant cryptography techniques.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If traditional encryption techniques are used, then processing speed and simplicity are improved, but quantum security resilience deteriorates
Solution Approach 1:
The patent merges classical encryption techniques with quantum key distribution by embedding quantum-encrypted keys within classical data packets. This allows the system to maintain the processing speed of classical encryption while incorporating quantum security resilience through the embedded quantum keys, effectively resolving the contradiction between speed and security.
Solution Approach 2:
The patent creates a composite security system that combines classical cryptographic methods with quantum key distribution. The classical encryption provides fast processing while the quantum-encrypted keys provide security resilience, forming a composite solution that leverages the strengths of both approaches.
2Reliability
If pure quantum key distribution is used, then quantum security resilience is improved, but key transfer rate and economic viability deteriorate
Solution Approach 1:
The patent combines quantum key distribution with classical data transmission by embedding quantum-encrypted keys within classical packets. This hybrid approach enables the system to achieve both high key transfer rates through classical channels and quantum security resilience through the embedded quantum keys, resolving the contradiction between security and productivity.
Solution Approach 2:
The patent uses classical data packets as an intermediary to transport quantum-encrypted keys. This allows quantum keys to be transmitted through existing classical infrastructure, dramatically improving key transfer rates while maintaining quantum security resilience, thus resolving the contradiction between security and productivity.
3Reliability
If encryption is applied to all datacenter segments, then security coverage is improved, but computational resource consumption deteriorates
Solution Approach 1:
The patent segments the datacenter network into classical data packet channels and embedded quantum key channels. This segmentation allows quantum encryption to be applied selectively to key transmission portions while classical encryption handles bulk data, reducing overall computational resource consumption while maintaining comprehensive security coverage.
Solution Approach 2:
The patent extracts the quantum encryption function to handle only key generation and transmission, separating it from bulk data encryption. This extraction allows quantum security to be applied where most critical (key management) while using more efficient classical methods for less critical operations, reducing overall computational overhead.
