Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If different cryptographic software is developed for each communication partner and encryption scheme, then security and specificity are improved, but device complexity and adaptability deteriorate
Solution Approach 1:
The cipher engine is designed as a universal platform that can handle multiple cryptographic schemes (AES, RSA, ECC, ChaCha20, etc.) and serve multiple communication partners through a single software instance. The engine dynamically selects and configures appropriate cryptographic functions based on the communication partner and message type, eliminating the need for separate software for each partner while maintaining security specificity.
Solution Approach 2:
The cipher engine employs dynamic configuration where cryptographic schemes, keys, and parameters are selected and modified at runtime based on the communication partner identifier and message characteristics. This allows the system to adapt to different security requirements without requiring software changes or restarts, resolving the contradiction between maintaining specific security protocols and avoiding software complexity.
2Reliability
If cryptographic software is modified to use new encryption keys or schemes, then security is improved, but productivity and duration of action deteriorate due to stopping and restarting
Solution Approach 1:
The system pre-loads and maintains multiple cryptographic schemes and key pairs within the cipher engine before they are needed. When a communication partner or encryption scheme change is required, the engine can switch to a pre-configured scheme or dynamically generate new keys without interrupting the communication flow, thus maintaining productivity while improving security.
Solution Approach 2:
The cipher engine is designed to perform cryptographic operations continuously without stopping. The engine can dynamically update cryptographic parameters, switch between different encryption schemes, and manage multiple communication partners simultaneously, ensuring that security updates and key changes do not interrupt the communication stream and maintain continuous productive action.
3Reliability
If new software is developed for each new communication partner, then specificity and security are improved, but adaptability and productivity deteriorate
Solution Approach 1:
The cipher engine serves as a universal cryptographic platform that can accommodate multiple communication partners with different security requirements through a single software instance. The engine identifies the communication partner and automatically selects the appropriate cryptographic scheme and keys, providing partner-specific security without requiring separate software development for each partner.
Solution Approach 2:
The system maintains adaptability to different communication partners by dynamically changing cryptographic parameters such as encryption schemes, key lengths, and algorithm selections based on the partner identifier and security requirements. This allows the cipher engine to adapt to new partners and schemes without software modification, resolving the contradiction between partner-specific security and system adaptability.
