Automatic Wireless Authentication for Vehicle Access Points
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicles face challenges in establishing secure wireless connections with non-vehicle access points, particularly when pre-shared keys or passphrases change, requiring manual updates and differing credentials for various access points, which can be cumbersome and insecure.
Innovation Solution
A method and system for automatically establishing a secure wireless connection by transmitting encrypted access point credentials to vehicles, using a key for encryption and decryption, allowing vehicles to connect securely without manual input of new passphrases.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual updates of passphrases are required for secure wireless connections, then security can be maintained through passphrase changes, but ease of operation deteriorates due to cumbersome manual updates
Solution Approach 1:
The system enables self-service by allowing the vehicle to automatically obtain and update wireless credentials through the backend service facility without requiring manual user intervention. The vehicle autonomously requests, receives, and implements new passphrases or credentials, eliminating the need for users to manually update security credentials while maintaining security through automated credential rotation.
Solution Approach 2:
The backend service facility acts as an intermediary between the wireless access point and the vehicle. It manages credential distribution by securely transmitting encrypted credentials to the vehicle, which then uses these credentials to establish wireless connections. This intermediary handles the complexity of credential management, security key generation, and automated updates, resolving the contradiction between security maintenance and operational simplicity.
2Adaptability or versatility
If different credentials are used for various access points, then adaptability to different networks is improved, but device complexity increases due to managing multiple credentials
Solution Approach 1:
The system implements a universal credential management approach where the vehicle is equipped with a cryptographic module capable of generating and storing multiple security credentials (passphrases, pre-shared keys, certificates). This single multi-functional module handles all credential types for all access points, eliminating the need for separate management systems for each credential while maintaining adaptability to different wireless networks and authentication protocols.
Solution Approach 2:
The backend service facility serves as a centralized intermediary that manages all credential distribution for the vehicle across multiple access points. Instead of the vehicle managing separate credentials for each network, the backend service facility securely distributes appropriate credentials to the vehicle's cryptographic module, which then handles authentication with any access point. This centralizes complexity in the backend system while keeping the vehicle system simple and adaptable.

AI summary
A system and method of automatically establishing a secure wireless connection, the method comprising: transmitting a wireless signal indicating availability of a secured wireless service; receiving a request from a vehicle in response to the wireless signal; in response to receiving the request, sending a message via wireless communications to the vehicle, wherein the message includes encrypted access point credentials, and wherein the encrypted access point credentials are encrypted using a key; and establishing a secure wireless connection with the vehicle based on receipt of access point credentials in one or more messages sent from the vehicle.
