Automotive Detection Device Channel Binding Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies for secure communication in the automotive and Industry 4.0 environments, such as ISO 15118, require separate protection for wireless communication connections and encapsulation protocols to prevent hijacking, which complicates the provision of Value Added Services (VAS) and real-time control communications.
Innovation Solution
A method that provides cryptographic security on the transport level for initial communication connections, generates and uses network access configuration data to establish a second, cryptographically protected communication connection, ensuring secure and tamperproof communication by binding the second connection to the first, with automatic termination and dynamic configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate protection and encapsulation protocols are used for wireless communication connections, then security against hijacking is improved, but device complexity and configuration requirements increase
Solution Approach 1:
The patent combines the security protection mechanism with the communication connection establishment process. The channel binding technology integrates cryptographic verification directly into the connection setup, eliminating the need for separate encapsulation protocols and reducing configuration complexity while maintaining security against hijacking.
Solution Approach 2:
The patent introduces channel binding as an intermediary mechanism that links the communication channel to cryptographic authentication. This intermediary layer provides security protection without requiring complex encapsulation protocols, simplifying the overall system architecture while preventing connection hijacking.
2Reliability
If channel binding is used to bind second communication connection to first connection, then security against tampering is improved, but communication protocol flexibility is reduced
Solution Approach 1:
The patent segments the security mechanism into channel binding operations that work independently of specific communication protocols. The binding process operates at a lower level, allowing different protocols (TCP, UDP, WebSocket, etc.) to be used at the application layer without compromising security, thus maintaining protocol flexibility while providing tamperproof protection.
Solution Approach 2:
The channel binding mechanism is designed to be protocol-agnostic, serving multiple communication protocols simultaneously. The same binding process can secure TCP connections, UDP communications, and other protocols, making the security solution universal and adaptable to various communication needs without restricting protocol choice.
3Reliability
If cryptographic security is provided on transport level for first connection, then security is improved, but additional configuration for second connection is required
Solution Approach 1:
The patent performs cryptographic security setup in advance during the first connection establishment. The channel binding information and cryptographic parameters are prepared and stored beforehand, allowing the second connection to be established without additional configuration effort. The preliminary cryptographic setup automatically applies to subsequent connections.
Solution Approach 2:
The system automatically reuses the cryptographic security parameters from the first connection for the second connection through channel binding. The binding mechanism self-manages the security configuration, eliminating the need for manual reconfiguration and reducing operational effort while maintaining cryptographic security.
