Vehicular Data Conversion Device for Secure Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies are insufficient in enhancing the security performance of vehicle data, as highly confidential data can be directly accessed and misused when transmitted outside the vehicle, leading to potential manipulation or misuse.
Innovation Solution
A vehicular data conversion apparatus and method that acquires vehicle data, processes it based on classification levels, and outputs the data after applying appropriate data processing methods such as resolution reduction, update cycle modification, and encryption, ensuring secure transmission according to the access control list stored in the apparatus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If vehicle data is directly transmitted outside the vehicle, then data accessibility and transmission speed are improved, but security performance deteriorates due to potential unauthorized access and misuse
Solution Approach 1:
The patent introduces a data transmission management device as an intermediary between the vehicle data transmission system and external devices. This mediator authenticates transmission requests, manages authentication information, and controls data transmission based on predefined policies, thereby enabling secure data sharing without direct access between vehicles and external devices
Solution Approach 2:
The patent segments authentication management into multiple components: authentication information management unit, transmission request authentication unit, and policy-based access control. This segmentation allows each component to handle specific security tasks independently, improving both security performance and system manageability
2Reliability
If authentication technology is applied to vehicle data transmission, then security performance is improved, but system complexity increases due to additional authentication mechanisms
Solution Approach 1:
The data transmission management device performs multiple functions including authentication information management, transmission request authentication, and policy enforcement within a single integrated system. This multi-functionality reduces overall system complexity compared to having separate authentication and transmission management systems
Solution Approach 2:
The system automatically manages authentication information and performs authentication checks without requiring manual intervention for each data transmission request. The automated authentication process reduces operational complexity while maintaining security
