Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If ASICs are designed to perform only one specific cryptographic application, then computational speed is improved, but flexibility and adaptability deteriorate
Solution Approach 1:
The patent implements a configurable transformation block within the cryptographic ASIC that can be programmed to perform different transformation functions. This allows the same hardware circuit to adapt to multiple cryptographic applications and algorithms, resolving the contradiction between specialized speed and general flexibility by enabling a single device to serve multiple purposes through reconfiguration
2Device complexity
If cryptographic circuits use fixed transformation functions, then device complexity is reduced, but security and adaptability deteriorate
Solution Approach 1:
The patent introduces a dynamically reconfigurable transformation block that can change its operation based on configuration inputs. The circuit transitions from a static, fixed-function design to a dynamic, adaptable structure where transformation parameters can be modified without changing the physical hardware, thereby enhancing security while maintaining manageable complexity through systematic design
3Adaptability or versatility
If separate transformation blocks and hashing blocks are used, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent merges the transformation block and hashing block into a unified integrated circuit structure with shared resources and coordinated operation. By combining these functions into a single cohesive unit rather than separate independent blocks, the design reduces overall device complexity while preserving adaptability through the configurable transformation capabilities within the integrated architecture
