Autonomous Vehicle Authorization System for Spoofing Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous vehicles are vulnerable to being compromised by nefarious actors who can send false instructions or take control of their control systems, leading to unauthorized navigation and potential safety risks.
Innovation Solution
Implementing a system that determines the actual location of an autonomous vehicle by comparing sensor data with map data and analyzing discrepancies to identify unauthorized deviations, and using frequency data to authenticate legitimate requests, thereby preventing unauthorized control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If autonomous vehicles navigate using control system instructions received over networks, then productivity and service capability are improved, but vulnerability to nefarious actors and unauthorized control increases
Solution Approach 1:
The patent introduces an authorization system as an intermediary component that mediates between the control system and the vehicle. This authorization system verifies whether received instructions are authorized before executing them, thereby preventing unauthorized control while maintaining the ability to receive control instructions over networks for productivity improvement
Solution Approach 2:
The patent implements feedback mechanisms where the authorization system continuously monitors and verifies the authenticity of control instructions. By checking authorization status and providing feedback on whether instructions are valid, the system prevents unauthorized control while maintaining legitimate communication channels for service operations
2Reliability
If the vehicle determines location using sensor data and map data comparison, then reliability and security are improved, but device complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-storing map data in the vehicle's memory before the vehicle needs to determine its location. By having map data readily available, the vehicle can quickly compare sensor data against known map information to verify its location and detect unauthorized deviations, improving security without requiring complex real-time processing
Solution Approach 2:
The patent uses copying by storing copies of map data in the vehicle's memory system. Instead of requiring complex real-time communication with external systems, the vehicle has local copies of map information that it can compare against sensor data to determine location and detect spoofing, thereby improving reliability while managing system complexity

AI summary
Techniques and methods for security vehicle systems. For instance, a control system may receive a reported location of a vehicle. The control system may then receive sensor data generated by the vehicle. After receiving the sensor data, the control system may analyze the sensor data with respect to additional data associated with the reported location. The additional data may include map data representing the reported location and/or additional sensor data received from another vehicle or user device. The control system may determine whether the vehicle is at the reported location. If the control system determines that the vehicle is at the reported location, the control system may determine that the vehicle is not compromised. However, if the control system determines that the vehicle is not at the reported location, the control system may determine that the vehicle is compromised and may then perform one or more remedial actions.
