Vehicle On-board Device Secure Data Transfer via Dynamic Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current data exchange methods between on-board devices and external service devices in vehicles face security risks and limitations in data transfer rates, with physical connections offering high speeds but security vulnerabilities, while wireless connections provide security but lower speeds and higher costs.
Innovation Solution
An on-board device with a communication module that can be switched between activated and deactivated states, allowing secure data transfer only when activated, enabling high-speed data transfer through any connection type, including physical or wireless, and using standardized connectors like USB for efficient data exchange.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a physical data connection is used for data exchange between on-board device and external service device, then data transfer rate is improved, but security against unauthorized access deteriorates
Solution Approach 1:
The patent applies preliminary action by requiring authentication and authorization to be established before the data connection is physically established. The external service device must first authenticate with the on-board device's electronic control unit, receive authorization, and only then is the physical data connection allowed to be connected. This prevents unauthorized access while maintaining high data transfer rates through physical connections.
2Reliability
If a wireless data connection is used for data exchange between on-board device and external service device, then security against unauthorized access is improved, but data transfer rate deteriorates
Solution Approach 1:
The patent applies dynamics by making the communication interface configurable to switch between different connection types (wireless and physical) based on security requirements and operational context. The system dynamically selects the appropriate connection mode: wireless connections for routine secure communications and physical connections for high-speed data transfers when authorized, thus optimizing both security and data transfer rate.
3Reliability
If authentication and authorization procedures are implemented before data connection, then security is improved, but complexity of the data exchange process increases
Solution Approach 1:
The patent applies self-service by implementing automated authentication and authorization procedures where the electronic control unit automatically verifies credentials, checks authorization levels, and manages connection permissions without requiring manual intervention. This automation reduces the perceived complexity for users while maintaining robust security protocols in the background.
