Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing AVN systems in vehicles face security issues due to easy network accessibility, allowing unauthorized users to connect using simple passwords, necessitating a method to restrict network access to specific mobile terminals.
Innovation Solution
A terminal authentication system and method that involves acquiring unique identification information, generating a network authentication certificate, copying it to the terminal, and using a network authentication application for secure wired/wireless authentication, with the Android Debug Bridge facilitating this process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If network access is made easy through AVN system or simple password, then ease of operation is improved, but security is worsened allowing unauthorized access
Solution Approach 1:
The system performs preliminary authentication actions before granting network access. The authentication controller generates a certificate using the terminal's unique identification information (MAC address) and copies it to the terminal in advance. The network authentication application is pre-installed and configured to use this certificate, ensuring that only authenticated terminals can access the network while maintaining ease of operation for authorized users.
2Reliability
If authentication procedure is made robust to prevent unauthorized access, then security is improved, but device complexity is worsened
Solution Approach 1:
The authentication controller generates a certificate of network authentication using the terminal's unique identification information and copies this certificate to the terminal. This copying mechanism simplifies the authentication process by providing the terminal with a reusable authentication credential, reducing the complexity of repeated authentication procedures while maintaining strong security through certificate-based authentication.
Solution Approach 2:
The patent introduces a certificate as an intermediary element between the authentication controller and the terminal. This certificate serves as a mediator that carries the authentication information, allowing the terminal to prove its identity to the network without requiring complex real-time verification protocols, thus reducing system complexity while maintaining security.
Data Source
AI summary
A terminal authentication method for vehicle network connection is disclosed. The terminal authentication method includes acquiring unique identification information of a terminal, generating a certificate of network authentication using the unique identification information, copying the generated certificate of network authentication in the terminal, and performing authentication of the terminal access to a network using a network authentication application in the terminal and the copied certificate of network authentication.
