Vehicle Component Release Using In-Operation Message Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for securing transportation vehicle components lack an efficient way to authenticate and release components for use only within the intended vehicle, leading to potential theft and misuse.
Innovation Solution
A device and method utilizing messages exchanged during regular vehicle operation to verify the identity of components, employing cryptographically secured messages and plausibility checks to ensure components are only released when in the correct vehicle, reducing the need for explicit two-way communication and enhancing security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If explicit two-way communication is used for authentication between vehicle components, then security against theft and misuse is improved, but communication overhead and system complexity increase
Solution Approach 1:
The vehicle component performs self-authentication by independently verifying cryptographic signatures of messages received from other components. Instead of requiring explicit two-way challenge-response communication, the component autonomously checks the authenticity of incoming messages using stored cryptographic keys, thereby reducing communication overhead while maintaining security.
Solution Approach 2:
Cryptographic keys and authentication data are pre-configured in the vehicle components during manufacturing or initial setup. This preliminary configuration enables components to perform security verification without requiring real-time two-way communication for key exchange, thus reducing communication overhead while ensuring security.
2Reliability
If cryptographic verification is performed on all incoming messages, then component identity authentication is improved, but processing time and computational load increase
Solution Approach 1:
The system performs cryptographic verification selectively rather than on all messages. Verification is triggered only when specific conditions are met, such as when a component needs to authenticate another component's identity or when suspicious activity is detected. This partial verification approach reduces processing time while maintaining authentication accuracy where needed.
3Reliability
If vehicle components are released only after successful authentication, then prevention of theft and misuse is improved, but system operational readiness is delayed
Solution Approach 1:
Authentication data and cryptographic keys are pre-configured in components during manufacturing, and the authentication mechanism is pre-established in the system architecture. When components are installed or activated, they can quickly verify identities using pre-configured data, enabling rapid release for operation while maintaining theft prevention.
Solution Approach 2:
Components autonomously perform authentication verification without requiring manual intervention or extended system-wide authentication sequences. The self-service nature of the verification process allows components to be quickly released for operation once installed, improving operational readiness while maintaining security.

AI summary
Devices, methods, and a computer program for releasing transportation vehicle components and a vehicle-to-vehicle communication module. The device for releasing a vehicle component of a transportation vehicle includes at least one interface for communication with further vehicle components of the transportation vehicle and a control module for controlling the at least one interface to receive messages from the further vehicle components of the transportation vehicle and to verify the identity of the further vehicle components based on the received messages and the stored identification data of the further vehicle components. The messages on which the verification of the identity of the further vehicle components is based are messages used in regular operation of the vehicle component. The control module also releases the vehicle component in response to the identity of the further transportation vehicle components being consistent with the stored identification data of the further vehicle components.
