Vehicle Network Isolation for Safe Navigation After Cyber Compromise
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicles connected to wireless networks are vulnerable to cyberattacks, which can lead to compromised network situations where users lack mechanisms to disconnect from potentially hazardous networks, especially in situations where the system fails to detect abnormalities or lacks necessary features to communicate effective remedial actions.
Innovation Solution
Systems and methods that allow users to select disconnecting from a compromised wireless network, enabling the vehicle to navigate to a safe location by determining a driving route using locally stored navigation data or communicating with a different network-connected device, while the vehicle is disconnected from the compromised network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vehicle remains connected to the wireless network to maintain normal communication and navigation functions, then network connectivity and feature availability are improved, but vulnerability to cyberattacks and network compromise increases
Solution Approach 1:
The system segments network connectivity by maintaining connection to multiple different wireless networks simultaneously. When one network is compromised, the vehicle can disconnect from that specific network while remaining connected to alternative networks, thus isolating the harmful effect to a single network segment while preserving overall network functionality.
Solution Approach 2:
The system dynamically changes network parameters by switching between different wireless networks based on security conditions. When a network compromise is detected, the system changes the network connection parameter from the compromised network to an alternative network, thereby adapting to the changing security environment while maintaining connectivity.
2Object-affected harmful factors
If the system automatically disconnects from the wireless network upon detecting potential compromise, then security is improved, but loss of navigation and communication capabilities worsens
Solution Approach 1:
The system performs preliminary actions by storing navigation data locally before network disconnection occurs. This ensures that essential navigation information is already available in the vehicle's memory, preventing any loss of navigation capability when the network connection is severed due to security concerns.
Solution Approach 2:
The system prepares compensatory measures in advance by maintaining local copies of navigation data and having alternative networks ready. When a network compromise occurs, these pre-prepared resources cushion the impact, ensuring continuous navigation functionality without interruption or data loss.
3Reliability
If the vehicle uses locally stored navigation data for route determination, then navigation reliability during network disconnection is improved, but navigation accuracy and real-time updates deteriorate
Solution Approach 1:
The system implements feedback by continuously monitoring the availability and security status of wireless networks. When an alternative network becomes available and secure, the system automatically reconnects to it, allowing real-time navigation updates and improving route accuracy while maintaining the reliability gained from local data storage during disconnection periods.

AI summary
Systems and methods are described for receiving a user selection indicating that a wireless network of a vehicle has been compromised; in response to receiving the user selection, causing the vehicle to be disconnected from the compromised wireless network; and while the vehicle is disconnected from the compromised wireless network performing a remedial action to enable the vehicle to navigate from a current location of the vehicle to a safe location.
