Vehicle Software Manipulation Mitigation via Data Traffic Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for detecting and mitigating software manipulation in vehicle electrical systems are complex and time-consuming, leading to potential disruptions in vehicle operation and safety, as they often require significant time to reset manipulated software and may leave weak points exploitable by intruders.
Innovation Solution
A computer-implemented method and system that utilizes a central device within the vehicle electrical system to recognize software manipulation and initiate targeted countermeasures, such as deactivating exploited interfaces, based on analysis of data traffic patterns to prevent repetition and maintain vehicle functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If software manipulation is detected using conventional methods (reset at repair shop or remote software request), then the manipulation is remedied, but significant time delays occur and vehicle operation is disrupted
Solution Approach 1:
The patent implements preliminary action by pre-storing multiple software versions and countermeasure configurations in the vehicle's memory before any manipulation occurs. When manipulation is detected, the system can immediately switch to a pre-prepared countermeasure or alternative software version without waiting for external intervention, thus eliminating the time delay while maintaining software security
Solution Approach 2:
The patent introduces an intermediary component - a dedicated countermeasure management system that acts as a mediator between the detected manipulation and the remediation process. This intermediary automatically selects and applies appropriate countermeasures from pre-stored options, enabling rapid response without direct human intervention or complex remote communication, thereby reducing time loss while ensuring reliable software security
2Reliability
If software manipulation is mitigated by resetting manipulated software, then the manipulation is remedied, but weak points remain exploitable by intruders for repeated attacks
Solution Approach 1:
The patent implements feedback by continuously monitoring data traffic and system states after countermeasures are applied. The system analyzes information about data traffic patterns to detect whether manipulation attempts are recurring, and automatically adjusts countermeasures based on this feedback. This closed-loop approach ensures that weak points are identified and addressed, preventing repeated attacks while maintaining software security
Solution Approach 2:
The patent applies preliminary anti-action by proactively implementing countermeasures that not only remediate current manipulation but also preemptively block potential repeated attacks. The system analyzes data traffic information to identify exploitation channels and applies targeted countermeasures (such as isolating affected components or blocking specific communication paths) before intruders can exploit the same weak points again, thus preventing harmful factors while ensuring security
3Object-affected harmful factors
If targeted countermeasures are implemented based on data traffic analysis, then repeated manipulation is prevented, but system complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the countermeasure system into modular, independent components: a data traffic analysis module, a manipulation detection module, a countermeasure selection module, and an execution module. Each module performs a specific function and can be independently managed. This segmentation reduces system complexity by making the overall system more manageable and easier to implement while still achieving the goal of preventing repeated manipulation attacks through targeted countermeasures

AI summary
A computer-implemented method. The method includes recognizing the possibility of a manipulation of the software of a first component of a plurality of components of a vehicle electrical system of a vehicle in a central device for mitigating a manipulation of software. The central device is part of the vehicle electrical system, and mitigates a manipulation of software in each component of the plurality of components. The method further includes initiating a countermeasure for mitigating the manipulation of the software of the first component by the central device; and carrying out the countermeasure for mitigating the manipulation of the software of the first component. The countermeasure for mitigating the manipulation includes a measure for preventing a repetition of the manipulation, which is selected based on an analysis of information concerning data traffic in the vehicle electrical system that took place before the possibility of a manipulation was recognized.
