5G DS-TT Authentication via Transparent Wireless Forwarding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G wireless networks, there is a risk of unauthorized electronic intrusion that can maliciously control Time-Sensitive Networking (TSN) devices, potentially disrupting the synchronization of time-aware systems and networks, which can impact the coordination and communication across local and core networks.
Innovation Solution
Implementing a system where device-side translator functions (DS-TT) in 5G wireless networks are authenticated through the transparent wireless forwarding of identity and credential values, formatted as Port Management Information containers, to ensure only authorized devices can participate in the selection of the best master clock, thereby preventing malicious control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If DS-TT functions are allowed to participate in master clock selection without authentication, then network synchronization functionality is maintained, but the network becomes vulnerable to malicious intrusion and unauthorized control
Solution Approach 1:
The patent implements authentication of DS-TT functions before allowing them to participate in master clock selection. The authentication mechanism verifies identity and credential values in advance, ensuring that only authorized devices can join the synchronization process. This preliminary security check prevents malicious intruders from compromising the network while maintaining the integrity of time-sensitive communications.
2Object-affected harmful factors
If authentication mechanisms are implemented for DS-TT functions, then network security against malicious intrusion is improved, but the complexity of the system increases
Solution Approach 1:
The patent introduces an authentication server as an intermediary component that handles the verification of DS-TT functions. This server receives identity and credential values from attempting devices, performs authentication, and grants or denies access to master clock selection participation. By centralizing the authentication logic in a dedicated intermediary component, the system achieves robust security without distributing complex authentication code across all network devices.
3Productivity
If transparent wireless forwarding of identity and credential values is implemented, then authentication efficiency is maintained, but the risk of credential interception during transmission increases
Solution Approach 1:
The patent replaces physical security measures with cryptographic authentication mechanisms. Instead of relying on secure physical channels for credential transmission, the system uses encrypted digital credentials and authentication protocols that can be transmitted wirelessly. The authentication server verifies these cryptographic credentials to authenticate DS-TT functions, maintaining security through mathematical rather than physical means.

AI summary
Device-side, translator functions may be authenticated by elements of a 5G core network before communications involving such functions are allowed to occur, or continue to occur.
