SOCKS Proxy for Secure DNS Resolution in Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for securing internet-based communication within motor vehicles against DNS-spoofing attacks are complex, expensive, and inconvenient, failing to provide adequate data security and user comfort.
Innovation Solution
A method and system utilizing a SOCKS server as a proxy within a connection unit to manage user requests for internet connections, selecting a DNS server based on a network interface and utilizing an allocation table for secure and efficient communication, with optional encryption and eSIM card-based mobile communication for flexible access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complex encryption methods are used to secure communication against DNS-spoofing attacks, then data security is improved, but device complexity and cost increase
Solution Approach 1:
The patent introduces a proxy server as an intermediary component between the user terminal and the DNS server. This proxy server receives DNS requests from user terminals, resolves the domain names itself, and forwards the resolved IP addresses to the terminals. By using this intermediary, the system achieves secure communication without requiring complex encryption mechanisms, as the proxy server acts as a trusted mediator that prevents DNS-spoofing attacks through its centralized resolution process.
2Reliability
If complex encryption methods are used to secure communication, then data security is improved, but implementation cost increases
Solution Approach 1:
The proxy server serves as a cost-effective intermediary that provides security functions without requiring expensive encryption hardware or complex cryptographic protocols. The system uses standard DNS resolution mechanisms within the proxy server to achieve protection against DNS-spoofing attacks, avoiding the need for costly encryption implementations while maintaining data security.
3Reliability
If complex encryption methods are used to secure communication, then data security is improved, but user comfort decreases due to time consumption
Solution Approach 1:
The proxy server acts as a transparent intermediary that handles DNS resolution in the background without requiring user intervention. Users simply access websites through their terminals, and the proxy server automatically resolves domain names and manages secure communication. This approach provides data security while maintaining user comfort, as the security mechanisms operate transparently without adding noticeable delays or complexity for the end user.

AI summary
A method for regulating internet-based communication within a motor vehicle (26), comprising receiving a user request (40) by means of a connection unit from a user (4) and/or user terminal (4), the user request requesting a connection between the user (4) and/or user terminal (4) and a backend server (12, 14), , processing the user request (44) for selecting a specific network interface (24a, 24b, 24c, 24d) for connecting the user (4) and/or user terminal (4) to the backend server (12, 14) within the connection unit (6), and selecting (46) a specific DNS server (22a, 22b, 22c) based on the selected network interface (24a, 24b, 24c, 24d) for resolving the Uniform Resource Locator (URL) of the backend server (12, 14) to create a connection between the user (4) and/or user terminal (4) and the backend server (12, 14).
