Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mobile stations relay data between network entities without verification mechanisms, then device complexity is reduced and ease of operation is improved, but data integrity and reliability deteriorate
Solution Approach 1:
The patent implements feedback mechanisms where receiving mobile stations send acknowledgments back to transmitting mobile stations to confirm successful data relay. This feedback loop enables verification of data integrity without requiring complex centralized verification systems, thus improving reliability while maintaining acceptable device complexity
Solution Approach 2:
The patent introduces intermediary verification entities (such as network entities or trusted third parties) that mediate the verification process between mobile stations. These intermediaries handle the complex verification tasks, allowing mobile stations to maintain simpler architectures while still achieving high data integrity through the intermediary's verification services
2Reliability
If digitally signed acknowledgements are implemented for data relay verification, then data integrity is improved, but processing time and energy consumption increase
Solution Approach 1:
The patent applies preliminary action by pre-computing and storing digital signatures or verification keys before data relay operations. Mobile stations prepare verification credentials in advance, so that during actual data relay, the verification process can proceed more quickly without extensive real-time computation, thus reducing time loss while maintaining verification reliability
Solution Approach 2:
The patent employs parameter changes by adjusting the cryptographic strength and complexity of digital signatures based on the specific requirements of different data relay scenarios. For less critical data, simpler verification parameters are used to reduce processing time, while for critical data, stronger verification parameters are applied, thus optimizing the balance between verification reliability and time consumption
