Traffic Node Manager for V2X Link Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Vehicle-to-Everything (V2X) communication systems lack effective security measures to prevent malicious nodes from establishing unauthorized communication links, leading to potential safety risks and network interference.
Innovation Solution
An apparatus and method that manage communication links by comparing object description information from requesting traffic nodes with stored information to determine the likelihood of legitimacy, allowing secure link establishment and prioritization of requests based on validity and message urgency, using a traffic node manager to intervene in direct communication requests.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If direct communication between traffic nodes is enabled without verification, then communication speed and ease of operation are improved, but security and reliability deteriorate due to malicious nodes
Solution Approach 1:
The system performs preliminary verification of communication requests by comparing object description information (such as sensor data about surrounding traffic nodes) with expected information before establishing direct communication links. This advance validation prevents malicious nodes from establishing unauthorized connections while maintaining fast communication for legitimate nodes.
Solution Approach 2:
The communication management apparatus acts as an intermediary between traffic nodes, receiving communication requests and verifying them against stored object description information. This mediator validates the legitimacy of requests by checking consistency with sensor observations, thereby securing communications without preventing direct node-to-node communication once validated.
2Reliability
If communication requests are verified by comparing object description information, then security and reliability are improved, but processing time and device complexity increase
Solution Approach 1:
The system performs verification selectively rather than universally - it compares object description information for communication requests that require validation, while allowing established legitimate nodes to communicate more directly. The verification process checks critical elements of object descriptions (such as presence and position of traffic nodes) without requiring complete re-verification of all parameters, thus balancing security with processing efficiency.
3Measurement precision
If object description information is compared with stored information for each request, then accuracy of legitimacy determination is improved, but processing complexity and time increase
Solution Approach 1:
The verification system focuses on validating specific critical local characteristics of object description information rather than performing exhaustive comparison of all parameters. It checks key elements such as the presence, position, and basic attributes of surrounding traffic nodes that are most relevant to communication legitimacy, while allowing less critical parameters to be verified with lower precision or cached from previous validations.

AI summary
An apparatus for managing communication links with a plurality of traffic nodes registered with a radio network configured to receive a request from a first traffic node to establish a communication link with a second traffic node, which is one of the plurality of traffic nodes. The apparatus further receives, from the first traffic node, object description information associated with the request, compares the object description information with stored information relating to at least some of the plurality of traffic nodes, determines, based on the comparison, a likelihood that the object description information pertains to the second traffic node and decides, in dependence on the determination, whether to grant the request. The apparatus is able to act as a traffic node manager for the radio network and could be a network node such as a Base Station or Base Transceiver Station or a dedicated vehicle identity manager for example.
