Vehicle Wireless Connection Authentication via Central Server
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for establishing wireless connections between mobile communication devices and vehicle communication modules lack secure and unique user authentication, leading to potential errors and damage when multiple users access different vehicles, and fail to provide easy and configurable access control.
Innovation Solution
A method where vehicle and user identifiers are stored on a server, allowing the mobile communication device to transmit these identifiers for authentication, with the server verifying access rights and providing connection data only if authorized, enabling secure and unique connections through technologies like WLAN or Bluetooth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If access data is stored locally in mobile telephones for multiple vehicles, then users can access different vehicles, but mistakes and unauthorized access occur leading to substantial damage
Solution Approach 1:
A central server is introduced as an intermediary between the mobile communication device and the vehicle communication module. The server stores the mapping between user identifiers and vehicle identifiers, and validates access requests before establishing connections. This mediator prevents unauthorized access and mistakes by ensuring that only authorized user-vehicle combinations can connect, thus resolving the contradiction between versatile access capability and connection accuracy.
2Reliability
If authentication requirements are implemented for vehicle access, then unauthorized access is prevented, but connection establishment becomes more complex
Solution Approach 1:
The authentication process is designed to be transparent to the user. The mobile communication device automatically performs the authentication by transmitting the user identifier to the server and receiving connection data without requiring manual intervention. The server automatically validates credentials and provides access data, making the security process seamless and eliminating the need for users to manually configure complex authentication parameters.
3Reliability
If centralized server authentication is implemented, then access security and unique allocation are improved, but system complexity increases
Solution Approach 1:
The central server performs multiple functions: storing user-vehicle mappings, validating authentication credentials, managing access rights, and providing connection data. By consolidating these functions into a single multi-functional system, the patent avoids the need for multiple separate components (such as separate databases, authentication servers, and configuration systems), thus improving security while minimizing the increase in overall system complexity.

AI summary
A method for establishing a wireless connection between a mobile communication device and a communication module (14) of a vehicle (10) with an identifier (17) is disclosed. According to the method, access rights, namely links between vehicle identifiers (17) and user identifiers, as well as data required for establishing the wireless connection, are stored in a database server (16) outside of the mobile communication device. A control unit (11, 12) for carrying out the method is also disclosed.
