Bus System Gateway for Unauthorized Data Query Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing integration of IoT services in vehicles poses a risk of unintentional data access, as drivers cannot verify which data are being queried and when, leading to potential unauthorized data collection.
Innovation Solution
A method for operating a bus system that detects irregular data queries and allows for automatic blocking or interruption by monitoring messages, identifying new parties, and implementing measures such as deactivating power supply or sending self-deactivation messages to prevent further queries.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If data collection units are connected to the bus system for IoT services, then data transmission capability is improved, but data security and unauthorized access protection deteriorate
Solution Approach 1:
A gateway is introduced as an intermediary component between the bus system and data collection units. The gateway monitors incoming messages, detects login attempts from new parties, and controls access to the bus system. This mediator enables data transmission while providing a security layer that detects and can block unauthorized access attempts.
Solution Approach 2:
The system implements continuous monitoring of bus messages to detect login attempts and data queries. The gateway receives feedback about new parties attempting to access the system and can respond by blocking their access. This feedback mechanism enables real-time detection and response to potential security threats while maintaining system functionality.
2Object-affected harmful factors
If message monitoring is implemented to detect irregular data queries, then data protection is improved, but system complexity increases
Solution Approach 1:
The gateway performs multiple functions: it routes messages between bus systems, monitors for login attempts, detects irregular data queries, and controls access permissions. By consolidating these security and communication functions into a single multi-functional component, the system achieves comprehensive data protection without proportionally increasing overall system complexity.

AI summary
A method is provided for operating a bus system in particular of a motor vehicle, in which messages of the bus system are received, and as a function of these messages, it is detected whether a party of the bus system sending these messages is a party logging on to the bus system.
