Workshop WLAN Credential Validation for Vehicle Connectivity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicles face challenges in connecting to wireless networks at workshops due to varying network identities and the need for secure credential distribution, which is often controlled by workshop owners, making it difficult to establish direct communication.
Innovation Solution
A computer-implemented method that associates validity parameters with credentials for vehicle access, allowing secure and controlled connection by sending credentials to a remote server, which can be time or location-based, ensuring limited accessibility and secure communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If credentials are distributed to vehicles for wireless network access, then ease of operation is improved, but workshop data security deteriorates
Solution Approach 1:
The system performs preliminary actions by associating validity parameters with credentials before distribution to vehicles. The control unit checks these validity parameters (such as time-based expiration or usage counters) before granting network access, ensuring that credentials are only valid under specific conditions. This preliminary validation mechanism enables secure credential distribution while maintaining workshop data security.
2Ease of operation
If wireless network credentials are made available to vehicles, then ease of operation is improved, but reliability deteriorates due to uncontrolled access
Solution Approach 1:
The system implements dynamic control over credential validity by using validity parameters that can expire or become invalid based on time, usage count, or other conditions. The control unit dynamically checks these parameters against current conditions to determine whether to grant access. This dynamic validation ensures that access rights are not static but adapt to changing security requirements, maintaining both ease of operation and reliability.
3Device complexity
If direct wireless communication is implemented between vehicles and workshop networks, then device complexity is reduced, but adaptability deteriorates due to network identity variations
Solution Approach 1:
The system implements a universal credential validation mechanism that works across different wireless network configurations. The control unit checks validity parameters that are independent of specific network identities (SSIDs), allowing the same credential structure to adapt to varying workshop networks. This universal approach reduces device complexity while maintaining adaptability to different network environments.

AI summary
The invention relates to a computer-implemented method for connecting a vehicle to a wireless local network of a workshop, comprising: identifying at least one wireless local network configuration of the wireless local network, said wireless local network configuration being associated with credentials for using said wireless local network, associating at least one validity parameter to said credentials in order to allow limited accessibility for the vehicle to said wireless local network, sending to a remote server said credentials, thereby enabling said credentials to be provided to the vehicle, upon receipt of a connection request including the credentials from the vehicle, checking the at least one validity parameter to determine that the credentials are still valid for the vehicle, and upon determination that the credentials are still valid, allowing the vehicle to connect to the wireless local network of the workshop.
