Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If encryption/decryption, message authentication, and checksum processing are performed by separate hardware processing circuits, then processing speed is improved, but processing efficiency deteriorates due to multiple redundant accesses to the same data
Solution Approach 1:
The patent combines multiple separate processing circuits (encryption/decryption, message authentication, checksum) into a single integrated data processing unit. This unified structure processes all three types of data simultaneously in one pass, eliminating the need for multiple separate accesses to the same data and thereby resolving the contradiction between individual processing speed and overall processing efficiency.
Solution Approach 2:
The data processing unit is designed with multi-functionality to perform encryption/decryption, message authentication, and checksum processing within a single circuit. This universal processor can handle multiple processing types concurrently, allowing the system to maintain high speed while improving efficiency by avoiding redundant data accesses.
2Adaptability or versatility
If multiple types of processing are performed independently in separate layers, then each processing can be executed separately, but overlapping data reads and writes cause deterioration of processing efficiency
Solution Approach 1:
The patent merges multiple independent processing layers into a single integrated data processing unit that handles encryption/decryption, message authentication, and checksum processing simultaneously. This combination eliminates overlapping data accesses while maintaining the versatility to perform different processing types as needed.
Solution Approach 2:
The unified data processing unit enables continuous processing by reading data once and performing all necessary processing operations in sequence without interruption or redundant accesses. This continuous action eliminates the inefficiencies caused by separate layer processing while maintaining adaptability for different processing requirements.
