Vehicle Wireless Communication Security Status Assessment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication links between vehicle components and external partners, particularly in public or unsecured networks, are vulnerable to hacking due to potential security holes in software implementations, allowing unauthorized access and data manipulation.
Innovation Solution
A method and device that assess the communication status of wireless links, enabling or disabling data exchange and access based on security protocols, including encryption and authentication across various OSI layers, to prevent hacker intrusion by deactivating communication modules and ensuring secure communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless communication links are used for data exchange between vehicle components and external partners, then communication convenience and functionality are improved, but security vulnerability to hacking increases
Solution Approach 1:
The patent applies preliminary action by assessing the communication status of wireless links before allowing data exchange. The system proactively evaluates security parameters such as encryption methods, authentication mechanisms, and network trustworthiness in advance. Based on this preliminary assessment, the system decides whether to enable or disable communication modules, preventing potential hacking attempts before they can compromise vehicle components.
2Productivity
If communication modules are kept active for data exchange, then communication functionality is maintained, but risk of hacker intrusion increases
Solution Approach 1:
The patent applies dynamics by making the communication modules dynamically controllable based on real-time security assessments. The system can switch communication modules between active and inactive states depending on the assessed security status of wireless links. This dynamic adjustment allows the system to maintain communication functionality when safe while preventing hacker intrusion when risks are detected.
3Reliability
If security assessment mechanisms are implemented, then protection against hacking is improved, but system complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the security assessment into distinct functional modules that can be independently implemented and managed. The system separates communication status assessment, security parameter evaluation, and communication control into modular components. This modular approach allows security mechanisms to be integrated without overwhelming system complexity, as each module performs a specific function.
4Reliability
If communication status assessment is performed, then security of data exchange is improved, but communication time is increased
Solution Approach 1:
The patent applies preliminary action by performing security assessments before communication begins, so that once communication is established, data exchange can proceed without repeated time-consuming checks. The initial assessment caches security status information, allowing subsequent communications to be faster while maintaining security.

AI summary
A method, a device, and a communication system are provided for secure communication of at least one of multiple components of a vehicle with at least one external communication partner via a wireless communication link, the multiple components in each case including at least one communication module for data exchange. The method includes exchange of data packets between a transceiver device of the vehicle and an external transceiver station, a communication status of the wireless communication link being ascertained and a data exchange between the at least one component and/or the external communication partner on the one hand, and the others of the multiple components on the other hand and/or an access of the at least one component and/or of the external communication partner to the others of the multiple components being enabled or disabled as a function of the communication status. The device and the communication system are provided for implementing the method.
