Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex encryption algorithm is used to process the data, then the security of the data is improved, but the computing resources occupied increase and the calculation takes a long time
Solution Approach 1:
The encryption process is divided into multiple stages: generating random numbers, creating data mapping information, deriving first and second encryption keys, encrypting data description information, and encrypting the data itself. This segmentation allows each component to perform a specific function efficiently, avoiding the need for a single complex encryption algorithm while maintaining security.
Solution Approach 2:
The patent performs preliminary actions by generating random numbers and creating data mapping information before the actual encryption process. The data mapping information is pre-determined based on device information, and encryption keys are derived in advance. These preliminary steps enable the main encryption operation to be more efficient since the groundwork is already laid.
2Reliability
If a complex encryption algorithm is used to process the data, then the security of the data is improved, but the computing resources occupied increase
Solution Approach 1:
The patent changes parameters dynamically by using random numbers and device-specific information to generate encryption keys. Instead of using a fixed complex algorithm, the system adapts the encryption parameters based on the specific data and device context, allowing for more efficient resource utilization while maintaining security.
Solution Approach 2:
The patent introduces intermediary elements such as random numbers and data mapping information that facilitate the encryption process. These intermediaries act as mediators between the raw data and the encryption operation, enabling more efficient key derivation and data processing without requiring computationally intensive algorithms.
