Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If quantum key distribution (QKD) is used for secure data transmission, then security against quantum attacks is improved, but cost and implementation time increase significantly
Solution Approach 1:
The patent segments the data transmission process into multiple independent secure channels, each encrypted with separate quantum-safe keys. This allows the system to achieve quantum security without requiring a single complex QKD infrastructure, instead distributing security across multiple simpler channels that can be implemented independently
Solution Approach 2:
The patent introduces a quantum cloud platform as an intermediary service that provides quantum-safe encryption and key management capabilities. This mediator handles the complex quantum cryptographic operations in the cloud, allowing endpoint devices to access secure transmission without implementing complex QKD systems locally
2Reliability
If data is split into encrypted shards and transmitted over multiple channels, then security and reliability are improved, but transmission time and complexity increase
Solution Approach 1:
The patent divides data into encrypted shards that can be transmitted simultaneously over multiple secure channels. This segmentation enables parallel transmission, improving throughput while maintaining security through independent encryption of each shard
Solution Approach 2:
The patent performs data splitting and encryption of individual shards as preliminary actions before transmission. By preparing encrypted shards in advance and transmitting them simultaneously over multiple channels, the system reduces overall transmission time while maintaining security
