Engineering Contradiction Analysis
1Reliability
If IC devices use proprietary and non-configurable encryption/decryption algorithms, then data security is provided, but users cannot select preferred security measures and the devices are vulnerable to attacks
Solution Approach 1:
The patent implements dynamic configurability of encryption and decryption algorithms in IC devices. The system allows users to select and configure different cryptographic standards (AES, DES, 3DES, RC4, RC5, RC6, IDEA, SAFER, Serpent, Twofish, Blowfish, CAST, LOCHS, MARS, Rijndael) through programmable logic circuits. This dynamic configuration capability resolves the contradiction by making the previously fixed proprietary algorithms changeable while maintaining security functionality.
Solution Approach 2:
The patent changes the parameter of algorithm configurability from fixed to variable. By implementing a configurable interface that allows selection of different cryptographic standards and key lengths, the system transforms the static encryption/decryption functionality into a dynamic parameter-driven system. This enables users to adapt security parameters to their specific needs while maintaining robust data protection.
2Object-affected harmful factors
If IC devices apply encryption and decryption algorithms to I/O data, then data protection against interception and alteration is achieved, but the proprietary nature restricts user control over security measures
Solution Approach 1:
The patent enables users to independently configure and control encryption/decryption settings in IC devices. Through the configurable interface, users can select their preferred cryptographic algorithms, manage keys, and adjust security parameters according to their specific requirements. This self-service capability resolves the contradiction by empowering users to control their own security measures rather than being restricted to proprietary defaults.
Solution Approach 2:
The patent implements a universal encryption/decryption framework that supports multiple cryptographic standards within a single IC device. The configurable logic circuits can be programmed to handle various algorithms (AES, DES, 3DES, RC4, RC5, RC6, IDEA, SAFER, Serpent, Twofish, Blowfish, CAST, LOCHS, MARS, Rijndael), making the device adaptable to different security requirements and applications while maintaining ease of use through a unified interface.
