Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If asymmetric key pairs are used for encryption, then security is improved, but computation cost increases
Solution Approach 1:
The patent segments the encryption system into two parts: asymmetric key pairs are used only for initial key exchange and authentication, while symmetric keys are used for actual message encryption. This division allows the system to benefit from the security of asymmetric encryption without bearing its high computational cost for all encryption operations.
Solution Approach 2:
The patent introduces symmetric keys as an intermediary between the asymmetric key exchange and the actual communication. The symmetric key acts as a mediator that is established through asymmetric encryption but then used for efficient symmetric encryption, bridging the gap between security requirements and computational efficiency.
2Reliability
If identity verification is performed for every message, then security is improved, but communication efficiency decreases
Solution Approach 1:
The patent performs identity verification and key exchange in advance before actual communication begins. Once identities are verified and symmetric keys are established, subsequent messages can be encrypted and transmitted without repeated verification processes, improving communication efficiency while maintaining security.
Solution Approach 2:
The patent implements periodic identity verification rather than verification for every single message. The verification is performed at predetermined intervals or when key expiration is reached, allowing efficient communication during verified periods while maintaining security through regular re-verification.
3Reliability
If certificates are frequently configured, then security is improved, but device complexity increases
Solution Approach 1:
The patent makes the asymmetric key pair serve multiple functions: authentication, key exchange, and establishing trust relationships. This multi-functionality reduces the need for separate certificate configurations for different purposes, simplifying device complexity while maintaining comprehensive security coverage.

AI summary
Embodiments of this application provide a communication method, apparatus, and system, to ensure secure and efficient communication when an unmanned aerial system accesses a mobile communication system. The method includes: Second user equipment sends a second message, first user equipment sends a first message to a network device in response to the second message, to request to perform identity verification on the second user equipment, and the network device verifies whether an identity of the second user equipment is valid, and sends, to the first user equipment, a verification result indicating whether the identity of the second user equipment is valid. Alternatively, the first user equipment sends a third message for request the second user equipment to reply with information used for remote identification, and the second user equipment replies with a fourth message, where the fourth message includes the information used for remote identification on the second user equipment, and the third message and the fourth message are encrypted by using corresponding keys.
