Remote Vehicle Control Message Broker Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote vehicle control systems are vulnerable to hacking, as malicious actors can fraudulently publish messages in message broker sections, allowing them to take control of vehicles remotely, necessitating improved security measures.
Innovation Solution
A remote vehicle control system incorporating a message broker with an actuator that verifies the authenticity of messages before transmitting commands to the vehicle, using authorization tokens encrypted and signed to ensure legitimacy and privacy, and partitioning communications to prevent direct exchanges between unauthorized terminals and vehicles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If direct communication between terminal and vehicle is enabled, then remote control functionality is achieved, but security vulnerability increases allowing fraudulent message publication
Solution Approach 1:
The patent introduces a message broker as an intermediary component between the terminal and vehicle. The broker receives messages from the terminal, validates them against authorization tokens, and only publishes validated commands to the vehicle. This mediator architecture enables remote control functionality while preventing fraudulent messages, as the broker acts as a security gatekeeper that verifies message authenticity before delivery.
2Adaptability or versatility
If message broker allows open message publication, then system accessibility is improved, but authorization verification becomes difficult
Solution Approach 1:
The patent implements preliminary authorization verification by requiring the terminal to present an authorization token with the message. The message broker validates this token before publishing the message to the vehicle. This preliminary check ensures that only authorized commands are transmitted, making authorization verification straightforward through token validation rather than requiring complex post-delivery verification.
3Reliability
If authorization tokens are implemented, then message authenticity is verified, but system complexity increases
Solution Approach 1:
The patent changes the parameter of message structure by adding an authorization token field to messages published by the terminal. This parameter change enables authenticity verification through token validation in the message broker, while the added complexity is confined to the message format and validation logic rather than requiring complex hardware or protocol changes throughout the entire system.

AI summary
The invention relates to a remote control system (100) for a vehicle (101) based on a terminal (102), comprising a message broker (103) comprising: - a first rubric (R1) for receiving at least one first message published by the terminal (102), said first message (M1) comprising a command, - a second rubric (R2) for receiving at least one second message (M2) intended for the vehicle (101), said system (100) being characterized in that it furthermore comprises an actuator (104) able to receive the first message (M1) and able to perform a verification on the first message (M1) and, if the verification of the first message (M1) is positive, to publish the second message (M2), in the second rubric (R2) so as to transmit the command to the vehicle.
