Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If identity verification is performed using conventional methods in unmanned aerial systems, then security can be maintained, but communication efficiency and resource utilization deteriorate due to lack of standardized protocols
Solution Approach 1:
The patent applies universality by enabling the unmanned aerial system to utilize the mobile communication network's existing identity verification infrastructure. The UAS device can authenticate through the network device using standard mobile communication protocols, making the verification process multi-functional by serving both UAS-specific security needs and general mobile network authentication requirements.
Solution Approach 2:
The network device serves as an intermediary between the UAS device and the verification system. Instead of direct peer-to-peer verification, the UAS device communicates authentication requests through the network device, which mediates the identity verification process and returns verification results, thereby improving communication efficiency through standardized protocols.
2Reliability
If asymmetric encryption is used for secure communication, then security is improved, but computational overhead and resource consumption increase
Solution Approach 1:
The patent changes the encryption parameter from asymmetric to symmetric encryption. The network device and UAS device use symmetric encryption algorithms for secure communication, which significantly reduces computational overhead and energy consumption while maintaining security requirements. This parameter change optimizes the balance between security and resource utilization in UAS operations.
3Reliability
If frequent certificate configurations are implemented for secure communication, then security is enhanced, but channel resource occupation and system complexity increase
Solution Approach 1:
The patent implements self-service by enabling the UAS device to automatically obtain and manage encryption certificates through the mobile communication network's existing infrastructure. The device can autonomously acquire certificates during network attachment or service activation, eliminating the need for manual configuration and reducing system complexity while maintaining frequent certificate updates for security.
