Segmented Vehicle Control Architecture with Remote Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle architectures are vulnerable to attacks due to numerous access points and interconnected systems, allowing hackers to gain remote control over critical functionalities like steering and braking.
Innovation Solution
A segmented architecture is introduced, where a human-machine interface receives requests and a separate vehicle control system implements actions, with requests being processed and authenticated in a remote computing environment to minimize direct communication and reduce attack surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a segmented architecture with remote authentication is implemented, then security against unauthorized access is improved, but system complexity and communication overhead increase
Solution Approach 1:
The vehicle control system is divided into distinct functional modules: a request receiving module that accepts control requests, an authentication module that verifies requester identity, and a control execution module that implements approved requests. This segmentation isolates security-critical functions and reduces the attack surface by limiting direct access to control mechanisms.
Solution Approach 2:
An authentication module acts as an intermediary between requesters and vehicle control systems. This mediator verifies requester identity and authorization before allowing control commands to reach the vehicle systems, preventing unauthorized access while maintaining legitimate control functionality.
2Ease of operation
If direct communication between user interfaces and vehicle control systems is maintained, then ease of operation is improved, but vulnerability to remote attacks increases
Solution Approach 1:
Authentication is performed preliminarily before any control commands are executed. The system verifies the identity and authorization of requesters in advance, establishing security checks before legitimate control operations can occur, thereby preventing malicious commands from reaching vehicle systems.
Solution Approach 2:
The authentication module serves as a protective intermediary that filters control requests. It allows legitimate remote control operations to proceed smoothly while blocking malicious commands, thus maintaining ease of operation for authorized users while reducing attack vulnerability.

AI summary
An architecture for receiving and responding to requests in a vehicle system may include transmitting requests to a remote processing system configured to verify the authenticity of requests and determine responsive actions. The action jobs may be maintained at a location remote from the vehicle, and the vehicle may be configured to retrieve action jobs from the remote location.
