Encrypted Visual Credential Transmission for Vehicle Workshop Network Access
Solution Overview
Problem
Privately owned workshops face challenges in securely connecting vehicles to their wireless networks due to varying SSIDs and sensitive credential management, making it difficult for vehicles to find and access valid networks without compromising sensitive data.
Innovation Solution
A computer-implemented method that sets limited validity for vehicle credentials, generates an encrypted visual representation, and uses validity parameters like time or location to control access, allowing secure and convenient connection to the workshop's wireless network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless network credentials are distributed to vehicles, then vehicle connectivity to the workshop network is enabled, but security control over sensitive data is compromised
Solution Approach 1:
The system performs preliminary actions by generating encrypted visual representations of credentials before the vehicle arrives at the workshop. These credentials are prepared in advance with embedded validity parameters, allowing the vehicle to connect immediately upon arrival without compromising security during the connection process.
Solution Approach 2:
The patent introduces an intermediary mechanism - encrypted visual representations (such as QR codes) that serve as a mediator between the credential storage system and the vehicle. This intermediary allows secure transmission of credentials without direct exposure of sensitive data, maintaining security control while enabling connectivity.
2Adaptability or versatility
If credentials are made available to multiple vehicles, then network accessibility is improved, but credential security is weakened
Solution Approach 1:
The system applies local quality by assigning unique validity parameters to each vehicle's credentials. Each encrypted visual representation contains vehicle-specific validity information (such as time windows or location constraints), allowing different vehicles to have different access conditions while maintaining overall credential security.
Solution Approach 2:
The credential system is segmented by dividing the master credential into multiple vehicle-specific encrypted visual representations. Each segment (vehicle credential) is valid only under specific conditions defined by its associated validity parameters, allowing broad network accessibility while maintaining security through segmentation.
3Speed
If wireless connection is established without physical interface, then connection speed is improved, but security risk increases
Solution Approach 1:
The patent replaces the mechanical connection interface (physical diagnostic cable connection) with a wireless communication system. This substitution enables faster connection speed while security is maintained through the use of encrypted visual representations and validity parameter verification, eliminating the need for physical contact points.

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, generating an encrypted visual representation of said credentials, thereby enabling the generated encrypted visual representation to be presented to a camera of the vehicle and decrypted to obtain said credentials, 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, upon determination that the credentials are still valid, allowing the vehicle to connect to the wireless local network of the workshop.
