1Reliability

If data is encrypted using traditional encryption methods, then data security is improved, but computational resource consumption increases

Engineering Contradiction:

Improvedata securityVSAvoidcomputational resource consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The encryption process is divided into two distinct stages: a first encryption stage using a first key, and a second encryption stage using a second key derived from the first. This segmentation allows the system to use simpler, less computationally intensive encryption methods while maintaining security through the layered approach, thereby reducing overall computational resource consumption.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system performs preliminary encryption actions by encrypting data with a first key before generating a second key from the first encrypted data. This preliminary action establishes a foundation that simplifies subsequent encryption operations and reduces the computational burden of later processing stages.

Solution Approach 1:

The encryption process is divided into two distinct stages: a first encryption stage using a first key, and a second encryption stage using a second key derived from the first encrypted data. This segmentation allows the system to use simpler, less computationally intensive encryption methods while maintaining security through the layered approach, thereby reducing overall computational resource consumption.

Inventive Principle:

Solution Approach 2:

The system employs a first key that can be discarded after use in the first encryption stage, and generates a second key from the encrypted output of the first stage. This approach allows the use of simpler, less expensive encryption operations in the second stage, improving processing speed while maintaining security through the initial stronger encryption layer.
