Supporting UE Identity Authentication for Secure Cooperative Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multiple user equipment cooperative communications, data transmission security is compromised when unrelated UEs are involved, leading to impaired user experience due to unauthorized data acquisition and transmission.
Innovation Solution
Implementing a method where supporting UE performs identity authentication on benefitted UE using a friend UE short-distance identifier list, ensuring only related UEs establish a communication link, thereby securing data transmission and enhancing user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If supporting UE allows any short-distance UE to access data transmission, then spectral utilization efficiency is improved, but data transmission security deteriorates
Solution Approach 1:
The patent applies preliminary action by performing identity authentication on the benefitted UE before establishing the cooperative communication link. The supporting UE checks whether the benefitted UE's identifier matches its pre-stored friend UE identifier list, and only after successful authentication does it proceed to receive and forward data. This pre-authentication mechanism ensures security is established before data transmission begins, resolving the contradiction between open access for spectral efficiency and security requirements.
2Reliability
If supporting UE performs identity authentication on benefitted UE, then data transmission security is improved, but communication establishment complexity increases
Solution Approach 1:
The patent applies local quality by implementing authentication only in the specific local context where the supporting UE needs to verify the benefitted UE's identity before data transmission. The authentication mechanism is not universally applied to all communication scenarios but is locally activated only when cooperative communication is initiated. This localized approach adds security where needed without unnecessarily complicating the entire communication system.
Solution Approach 2:
The patent uses copying by having the supporting UE pre-store a list of friend UE identifiers (a simplified copy of identity information) that can be quickly compared against the incoming benefitted UE's identifier. Instead of performing complex real-time identity verification, the system uses a pre-copied identifier list for rapid matching, reducing the computational complexity of the authentication process while maintaining security.
3Reliability
If supporting UE authenticates benefitted UE using friend UE identifier list, then user experience is improved through secure communication, but processing time increases
Solution Approach 1:
The patent applies copying by using pre-stored friend UE identifier lists that contain simplified identity information. When authentication is needed, the supporting UE performs a direct comparison between the benefitted UE's identifier and the pre-copied identifiers in its list, rather than performing complex real-time verification. This copying approach significantly reduces authentication processing time while maintaining security, thereby improving user experience without excessive time loss.

AI summary
Embodiments of the present disclosure provide a method that includes receiving, by supporting user equipment UE, a pairing request message sent by a network side; and acquiring, by the supporting UE, a friend UE short-distance identifier list when self supporting capability information of the supporting UE indicates that the supporting UE supports a friend UE. The method also includes performing, by the supporting UE, identity authentication on the benefitted UE according to the friend UE short-distance identifier list and a short-distance identifier of a benefitted UE that is carried in the pairing request message. The method also includes performing, by the supporting UE, pairing processing with the benefitted UE, and sending a pairing response message to the network side, if the benefitted UE has been authenticated.
