Vehicle Communication Restriction Device for Secure Group Messaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle-to-vehicle communication systems face challenges in restricting communication to specific groups of vehicles, leading to potential misuse and unauthorized participation.
Innovation Solution
An assistance system with a communication device and a restriction device that uses encryption and authentication to ensure only selected vehicles can participate in communication, with the restriction device integrated into vehicle components protected from unauthorized removal or installation, and keys stored in secure units like ESP controllers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If general broadcast communication is used between vehicles, then all vehicles in range can communicate with all other vehicles, but unauthorized vehicles can also participate in the communication
Solution Approach 1:
The patent introduces a restriction device as an intermediary component that mediates between the communication device and external vehicles. This restriction device checks authorization credentials and selectively permits or blocks communication access, thereby enabling secure group communication while preventing unauthorized participation. The restriction device acts as a gatekeeper that maintains both accessibility for authorized vehicles and security against unauthorized ones.
2Reliability
If a restriction device is added to limit communication to selected vehicles, then communication security is improved, but device complexity increases
Solution Approach 1:
The patent combines the restriction device with existing vehicle components that already have protection mechanisms against unauthorized removal and installation. By integrating the restriction device into components that are already secured and protected, the system leverages existing security infrastructure rather than adding entirely new separate systems. This merging approach reduces overall system complexity while maintaining the required communication security.
3Reliability
If encryption and authentication mechanisms are implemented, then unauthorized access is prevented, but processing time and computational resources increase
Solution Approach 1:
The patent performs authentication and authorization checks in advance before allowing communication to occur. The restriction device verifies credentials and establishes authorization status prior to initiating data transmission. This preliminary action ensures that only authorized vehicles are admitted to the communication group, preventing unauthorized access while minimizing processing delays during actual communication by having authentication already completed.
Data Source
AI summary
A method and assistance system drawn to identification-dependent communication that takes place between vehicles. The messages to be transmitted are encrypted by cryptographic methods, wherein the necessary keys for the cryptographic methods are stored in vehicle components which are protected from unauthorized removal and installation by means of protection mechanisms. The method and system make it possible to limit standardized broadcasts to a particular group of users.
