Adaptation Layer Identity Reconfiguration for Secure Relay Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication networks, especially for vehicle-to-everything (V2X) communication, there is a lack of effective security protection for the adaptation layer headers, which can lead to misuse of remote UE identities during relay communication, compromising network security.
Innovation Solution
Configuring and reconfiguring the identity of a remote UE within the adaptation layer, allowing nodes involved in relay communication to update the adaptation layer headers adaptively, ensuring secure handling of identities and preventing misuse.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If remote UE identity is carried in adaptation layer header for relay communication, then relay communication functionality is enabled, but security protection is lost and identity may be disclosed or misused
Solution Approach 1:
The patent implements dynamic identity management by enabling reconfiguration of the remote UE identity in the adaptation layer header. The identity can be changed from a first identity to a second identity through reconfiguration signaling, making the system adaptive to security requirements while maintaining relay communication functionality. This dynamic approach allows the identity to be updated periodically or based on security policies, preventing static identity exposure.
Solution Approach 2:
The patent changes the identity parameter in the adaptation layer header from a fixed value to a reconfigurable parameter. By allowing the remote UE identity to be reconfigured between different values (first identity and second identity), the system transforms a security vulnerability into a secure dynamic parameter that can adapt to different communication scenarios and security requirements.
2Object-affected harmful factors
If remote UE identity is reconfigured dynamically, then security is improved, but node coordination complexity increases
Solution Approach 1:
The patent introduces reconfiguration signaling as an intermediary mechanism to coordinate identity changes across multiple nodes. The signaling process acts as a mediator that synchronizes the identity updates between the remote UE, relay UE, and network nodes, ensuring that all parties receive and process the identity reconfiguration information in a coordinated manner, thereby managing the complexity of multi-node synchronization.
Solution Approach 2:
The patent implements feedback mechanisms through reconfiguration signaling that provides status information about identity changes to all involved nodes. The signaling includes feedback about whether the reconfiguration was successful, enabling nodes to adjust their behavior accordingly and maintain consistency across the relay communication path without requiring complex centralized coordination.
