Vehicle V2X Mutual Trust Platform for Cross-Entity Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the field of vehicle-to-everything (V2X) communication, vehicles from different entities such as alliance ecology, organizations, and vehicle companies cannot establish mutual trust and communication with V2X devices in intelligent traffic areas due to independent certificate systems, leading to communication barriers when entering intelligent traffic demonstration areas.
Innovation Solution
A vehicle communication method that acquires and utilizes verification information, including root and sub-verification information, from both the vehicle's entity and the intelligent traffic area, allowing vehicles to communicate securely with V2X devices within the intelligent traffic area through a mutual trust platform that manages certificate systems, enabling mutual trust and communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vehicles from different entities use independent certificate systems, then each entity can maintain its own trust management, but vehicles cannot establish mutual trust with V2X devices in intelligent traffic areas
Solution Approach 1:
The patent introduces a mutual trust platform as an intermediary between vehicles from different entities and V2X devices in intelligent traffic areas. This platform manages certificate systems and provides verification information that enables trust establishment across previously isolated certificate domains, allowing cross-entity communication while maintaining each entity's independent trust management
Solution Approach 2:
The mutual trust platform provides a universal verification mechanism that works across multiple independent certificate systems. By obtaining and utilizing both entity verification information and intelligent traffic area verification information, the system achieves multi-functional compatibility, enabling vehicles to communicate with V2X devices regardless of which entity they belong to
2Reliability
If vehicles obtain verification information from both entity and intelligent traffic area, then secure communication is enabled, but system complexity increases
Solution Approach 1:
The mutual trust platform acts as an intermediary that handles the complexity of managing multiple verification information sets. Vehicles obtain both entity verification information and intelligent traffic area verification information through this platform, which coordinates the interaction between different certificate systems and simplifies the overall verification process
Solution Approach 2:
The system performs preliminary actions by obtaining verification information from the mutual trust platform before actual communication occurs. This advance preparation includes acquiring both entity and area verification information, ensuring that all trust verification requirements are met before communication begins, thereby simplifying the communication process itself
