Autonomous Vehicle Control Interface With Authenticated Manual Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous vehicles lack secure mechanisms to ensure that only authorized external devices can manually control vehicle operations, such as steering and braking, during maintenance or repair, potentially allowing unauthorized access and control.
Innovation Solution
A control computer system that authenticates external control devices using encryption tokens and authentication signatures, ensuring only authorized devices can access and control vehicle operations by verifying keys and signatures through a vehicle communication network and potentially involving a third-party remote computer for additional authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual control interface is provided for autonomous vehicle, then ease of operation is improved, but security is worsened due to potential unauthorized access
Solution Approach 1:
An authentication system acts as an intermediary between the external control device and the vehicle's communication network. The system verifies authentication credentials (keys, signatures, tokens) before allowing any control commands to pass through, thereby enabling manual operation while blocking unauthorized access attempts.
Solution Approach 2:
Authentication verification is performed in advance before any control commands are executed. The system checks authentication credentials, validates digital signatures, and verifies tokens beforehand, ensuring that only authenticated devices can initiate control operations on the autonomous vehicle.
2Object-affected harmful factors
If authentication system is implemented, then security is improved, but device complexity is worsened
Solution Approach 1:
The authentication system is designed to work with multiple authentication methods (keys, digital signatures, tokens) within a single unified framework. This multi-functional approach allows the system to handle different authentication scenarios without requiring separate systems, thereby improving security while limiting the increase in complexity.
Solution Approach 2:
The authentication system automatically verifies credentials, validates signatures, and checks tokens without requiring manual intervention. The system self-manages the authentication process, reducing the operational complexity despite the enhanced security measures implemented.
Data Source
AI summary
A system includes a control computer that is programmed to perform an authentication based on an encryption key, upon being connected to a vehicle communication network. The computer is programmed to control vehicle operation including at least one of propulsion, braking, and steering, upon authentication by a vehicle computer that is physically attached to the communication network.
