Temporary ID Provisioning for Secure D2D Discovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless networks, establishing a direct connection between user equipment (UE) poses security risks due to the potential exposure of identifying information when broadcasting network identifiers, which can compromise network security.
Innovation Solution
Implementing a system where UEs are provisioned with temporary IDs by a D2D Server, allowing them to broadcast these IDs over separate radio resources, thereby maintaining anonymity and enhancing network security by preventing identification without additional information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If UEs broadcast their network identifier to establish direct connections, then direct connection establishment is enabled, but network security is compromised due to exposure of identifying information
Solution Approach 1:
The patent introduces a D2D Server as an intermediary that provisions temporary IDs to UEs. These temporary IDs act as mediators between the UE and the direct connection establishment process, allowing UEs to discover and connect with each other without exposing their permanent network identifiers. The temporary ID serves as a safe intermediary representation that enables discovery while protecting the UE's true identity.
Solution Approach 2:
The patent creates a copy of the UE's identity in the form of a temporary ID that is provisioned by the D2D Server. This temporary ID copy is used for broadcasting and discovery purposes, while the original permanent identifier remains protected and undisclosed. The copy enables the discovery function without compromising the security of the original identifier.
2Object-affected harmful factors
If UEs use temporary IDs for discovery, then network security is enhanced by preventing identification, but the complexity of the discovery system increases due to temporary ID provisioning
Solution Approach 1:
The D2D Server automatically provisions temporary IDs to UEs without requiring complex manual configuration or user intervention. The server manages the temporary ID lifecycle autonomously, generating, distributing, and potentially revoking temporary IDs as needed. This self-service approach minimizes the operational complexity despite introducing temporary ID management, as the system handles the complexity internally without burdening the end users or requiring complex coordination between multiple entities.

AI summary
In embodiments, apparatuses, methods, and storage media may be described for establishing a direct connection between two UEs. Each UE may be provisioned with a temporary identifier by a server of a wireless network of the UE. The UEs may then be configured to broadcast the temporary IDs in radio signals over radio resources that are separate from the radio resources of the network. The temporary IDs may not contain identifying information of the broadcasting UE that is interpretable without receiving further information from the network.
