Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If hardware system implementation is used for cryptography system, then performance is improved, but adaptability deteriorates
Solution Approach 1:
The patent applies dynamics by making the cryptography system reconfigurable through FPGA technology. The hardware can be dynamically reprogrammed to execute different crypto algorithms, transitioning from a static hardware implementation to a dynamic, adaptable system that maintains high performance while supporting multiple algorithms.
Solution Approach 2:
The patent implements universality by designing a cryptography system that can perform multiple functions through a single hardware platform. The FPGA-based architecture allows the same physical system to execute various crypto algorithms (AES, DES, RSA, etc.), making it a universal cryptography solution rather than a dedicated single-algorithm device.
2Productivity
If crypto algorithm is incorporated within hardware-based implementation, then performance is improved, but ease of operation deteriorates
Solution Approach 1:
The system uses FPGA reconfigurability to dynamically load and switch between different crypto algorithms through software updates. This allows the hardware to maintain high encryption rates while enabling easy upgradability and algorithm switching without physical modifications.
Solution Approach 2:
The patent implements preliminary action by pre-configuring the FPGA hardware architecture with reusable cryptographic building blocks and structures. This preliminary setup enables rapid algorithm switching and easy upgradability, as the basic infrastructure is already in place and only needs to be reprogrammed for different algorithms.
3Productivity
If hardware-based implementation is used, then performance is improved, but device complexity increases
Solution Approach 1:
The patent segments the cryptography system into distinct components: the FPGA hardware platform, the crypto algorithms stored externally, and the control software. This segmentation allows the system to achieve high performance through hardware acceleration while managing complexity by separating the algorithm logic from the execution platform, avoiding CCI classification.
Solution Approach 2:
The patent introduces an intermediary layer (the FPGA configuration memory and control software) between the hardware platform and the crypto algorithms. This intermediary allows the system to function as a high-performance hardware device while maintaining flexibility and avoiding the complexities associated with CCI status through proper architectural design.
4Adaptability or versatility
If processor-based implementation is used for cryptography system, then adaptability is improved, but performance deteriorates
Solution Approach 1:
The patent merges the advantages of both hardware and software approaches by combining FPGA reconfigurability with processor-based control. The FPGA provides hardware-level performance for encryption operations, while the processor handles algorithm selection and configuration, achieving both high adaptability and high performance.
Solution Approach 2:
The system achieves universality by using a single FPGA platform that can be configured to execute multiple crypto algorithms at hardware speeds. This multi-functional design allows the system to adapt to different algorithms while maintaining high encryption rates, overcoming the performance limitations of conventional processor-based implementations.
