Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If homomorphic encryption operations are performed on encrypted ciphertext, then data security is improved, but operation speed and processing efficiency deteriorate
Solution Approach 1:
The patent creates a simulation environment that copies the structure and behavior of the homomorphic encryption system without actually performing cryptographic operations. The simulator replicates encryption schemes, key management, and operation flows in plaintext, enabling fast verification while maintaining security testing capabilities without the computational overhead of real encrypted operations
Solution Approach 2:
The simulation apparatus acts as an intermediary between security verification and performance testing. It mediates by providing a middle-ground environment that mimics encrypted operation behavior without requiring actual cryptographic computation, thus bridging the gap between security requirements and speed requirements
2Ease of operation
If decryption is performed by the server to retrieve or process stored data, then data accessibility is improved, but resource consumption and time loss increase
Solution Approach 1:
The patent performs verification and testing actions in advance through the simulation environment before deploying actual homomorphic encryption operations. By pre-validating algorithms, operations, and system configurations in the simulator, the need for time-consuming decryption and re-verification during actual operations is reduced, enabling faster data processing
3Measurement precision
If homomorphic encryption systems are developed and verified using actual encrypted operations, then verification accuracy is improved, but development time and computational resources increase
Solution Approach 1:
The simulation apparatus creates accurate copies of the homomorphic encryption system's operational structure, algorithms, and data flows in plaintext form. This copying approach maintains verification accuracy by preserving the logical relationships and operational sequences while eliminating the computational burden of actual cryptographic operations, enabling rapid development and testing iterations
Solution Approach 2:
The patent changes the operational parameters from actual encrypted data to simulated plaintext representations that mirror the encryption structure. By transforming the verification medium while preserving the operational logic, the system maintains measurement precision for algorithm validation while dramatically improving development throughput and reducing resource consumption
