Engineering Contradiction Analysis
1Quantity of substance
If data compression is used to increase storage capacity, then storage efficiency improves, but data security deteriorates
Solution Approach 1:
The patent segments data into fixed-size blocks and applies separate encryption keys to each block. This segmentation allows the system to maintain high security through multiple independent encryption operations while achieving compression through selective storage of only encrypted block data, rather than storing entire files with traditional encryption methods.
Solution Approach 2:
The patent creates a composite encryption system that combines multiple encryption layers: initial block cipher encryption, followed by secondary encryption using generated keys, and optional tertiary encryption. This composite approach achieves both high security and compression efficiency by strategically applying different encryption methods to different data portions.
2Reliability
If traditional encryption methods are used to protect data, then data security improves, but computational power requirements increase
Solution Approach 1:
The patent applies partial encryption action by encrypting only the necessary portions of data with multiple key layers, rather than applying full-strength encryption to entire data sets. The system uses generated keys for secondary encryption on selected blocks, reducing overall computational overhead while maintaining security through targeted multi-layer protection on critical data segments.
3Reliability
If block cipher encryption is used to secure data transmission, then data security improves, but bandwidth requirements increase
Solution Approach 1:
The patent extracts and stores only the essential encrypted block data, omitting redundant information. By using fixed-size block encryption and generating keys selectively, the system extracts only the necessary security-critical components for transmission, reducing bandwidth consumption compared to transmitting entire encrypted files with traditional methods.
