Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In-vehicle communication devices face challenges in ensuring security due to limited resources and the need to communicate with insecure networks, such as the Internet, while maintaining robust authentication and security services.
Innovation Solution
A communication system with a storage for authentication data and a gateway that authenticates mobile communication terminals, using a controller to relay communications to security apparatuses based on authentication information, ensuring secure communication paths even through insecure networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If in-vehicle communication devices communicate directly with insecure networks like the Internet, then network connectivity and communication flexibility are improved, but security vulnerabilities and exposure to harmful factors increase
Solution Approach 1:
The patent introduces a security apparatus as an intermediary between the in-vehicle communication device and external networks. This security apparatus includes authentication functionality that verifies communication partners before allowing data transmission, thereby mediating the interaction and blocking unauthorized or malicious communications while permitting legitimate network access
2Reliability
If robust authentication and security services are implemented in in-vehicle communication devices, then security is improved, but device complexity and resource consumption increase
Solution Approach 1:
The patent extracts the authentication and security processing functions from the in-vehicle communication device and relocates them to a separate security apparatus. This extraction allows the in-vehicle device to maintain simple communication functionality while the security apparatus handles the complex authentication protocols and security services independently
3Speed
If authentication processing is performed locally in the in-vehicle communication device, then authentication speed is improved, but resource consumption and processing load increase
Solution Approach 1:
The security apparatus acts as an intermediary that specializes in authentication processing. It receives authentication requests from the in-vehicle communication device, performs the computationally intensive verification operations, and returns authentication results. This division allows fast authentication responses while the in-vehicle device consumes minimal resources
Data Source
AI summary
An information processing apparatus is arranged within a communication system that comprises a storage that stores authentication data for authenticating mobile communication terminals and a gateway that accommodates access from a first communication network. The communication system authenticates a mobile communication terminal connected via the first communication network and the gateway, using the authentication data. The information processing apparatus comprises a controller that relays communications from the mobile communication terminal to one or more security apparatuses based on information related to the authentication.
