V2X Vehicle Communication via Global Trust Platform
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
V2X vehicles from one intelligent transportation city cannot communicate with V2X devices in another city due to independent trusted root certificate lists, lacking a unified management platform for inter-city communication.
Innovation Solution
A global platform is introduced to maintain a corresponding relationship between mutual trust platforms and areas, allowing V2X vehicles to acquire and download the necessary trusted root certificate lists from the global platform, enabling communication across different city platforms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If each intelligent transportation city maintains its own independent mutual trust platform with separate trusted root certificate lists, then local communication security and reliability are ensured, but inter-city communication capability is lost
Solution Approach 1:
A global platform is introduced as an intermediary between multiple city-level mutual trust platforms. The global platform maintains a comprehensive trusted root certificate list that includes root certificates from multiple cities, while each city platform maintains its own local trusted root certificate list. This intermediary structure enables vehicles to acquire the necessary trust relationships for inter-city communication without compromising the security architecture of individual cities.
Solution Approach 2:
The global platform serves multiple functions: it maintains the comprehensive trusted root certificate list, provides certificate update services, and enables vehicles to communicate across different city platforms. By making the trust management system universal, vehicles can operate in any city that is registered with the global platform, enhancing the versatility of the V2X communication system.
2Adaptability or versatility
If a unified global platform is introduced to enable inter-city communication, then communication versatility across cities is improved, but system complexity increases
Solution Approach 1:
The trust management system is segmented into two independent but interconnected layers: city-level mutual trust platforms and a global platform. Each city platform handles local communication and maintains its own trusted root certificate list, while the global platform manages inter-city trust relationships. This segmentation allows each layer to operate independently, reducing the complexity burden on individual components while enabling comprehensive inter-city functionality.
Solution Approach 2:
The system transitions from a single-dimensional city-level trust management to a two-dimensional hierarchical structure. The global platform operates at the upper dimension, providing overarching trust management, while city platforms operate at the lower dimension, handling local communications. This dimensional change enables inter-city communication without requiring each city platform to directly manage all other cities, thus controlling complexity.
3Reliability
If vehicles continuously update trusted root certificate lists from multiple platforms, then communication reliability across cities is maintained, but information processing overhead increases
Solution Approach 1:
The global platform pre-maintains a comprehensive trusted root certificate list that includes root certificates from multiple city platforms. Vehicles can acquire this comprehensive list or incremental updates from the global platform before traveling to other cities, rather than needing to dynamically query and verify certificates from each city platform during communication. This preliminary action reduces real-time information processing overhead while maintaining communication reliability.

AI summary
The present disclosure discloses a communication method, apparatus for a vehicle and an electronic device, which relate to the field of artificial intelligence technology such as Vehicle to X, automatic driving and intelligent transportation. The specific scheme is: when it is determined that the vehicle travels to a target area, determining a target platform corresponding to the target area and a target download address corresponding to the target platform according to a corresponding relationship between mutual trust platforms and areas, and download addresses corresponding to the mutual trust platforms; acquiring download verification information generated by the target platform for the vehicle; downloading access verification information in the target platform according to the download verification information and the target download address; and communicating with a communication device in the target area according to the access verification information, thereby realizing communication between the vehicle and the communication device in the target area.
