Vehicle Communication Proxy With User-Authorized Data Channels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional remote vehicle communication methods lack user authorization, leading to security risks such as data leakage and malicious control due to direct communication between vehicles and remote servers or mobile apps without user consent.
Innovation Solution
Implementing a vehicle communication system with a secure communication server and proxy that requires user authorization for establishing a dedicated data channel, ensuring only authorized entities can communicate with the vehicle through an external interface, using encryption for secure data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If direct communication between vehicle and remote server is implemented, then remote control function is achieved, but security risk increases due to lack of user authorization
Solution Approach 1:
The patent introduces a client as an intermediary between the vehicle and the remote server. The client receives service requests from the remote server, verifies user authorization, and only then establishes data channels with the vehicle. This intermediary mechanism enables remote control functionality while ensuring that only authorized users can access vehicle data, thus resolving the security risk associated with direct communication.
2Reliability
If user authorization mechanism is added to prevent data leakage, then data security is improved, but communication complexity increases
Solution Approach 1:
The client acts as a centralized intermediary that handles all authorization logic and communication coordination. By concentrating the authorization mechanism in a single component rather than distributing it across multiple systems, the patent improves data security while minimizing the increase in overall system complexity. The client manages service requests, user verification, and data channel establishment in one place.
Solution Approach 2:
The patent segments the communication system into distinct functional components: the remote server, the client, and the vehicle-mounted proxy. Each component has a specific responsibility, with the client handling authorization and channel management. This segmentation allows the authorization mechanism to be added without significantly increasing the complexity of individual components, as each remains focused on its core function.
3Reliability
If client authorization is required for data channel establishment, then unauthorized access is prevented, but communication time increases
Solution Approach 1:
The patent implements preliminary user authorization through the client before data channel establishment. The client verifies user identity and obtains authorization tokens in advance. While this adds an initial authorization step, the actual data transmission once the channel is established occurs efficiently without repeated authorization checks, thus preventing unauthorized access while minimizing the time impact on legitimate communications.

AI summary
Disclosed are a vehicle communication method, system and device, and a storage medium. The method is applied to a secure communication server end in communication connection with a vehicle-mounted secure communication proxy end, and may include: receiving a target service request; sending an authorization request to a client corresponding to the vehicle-mounted secure communication proxy end according to the target service request; receiving an authorization response generated by the client according to the authorization request; and establishing, according to the authorization response, a data channel for communication connection between the vehicle-mounted secure communication proxy end and the secure communication server end.
