Vehicle Security Control for Safe Real-Time Attack Mitigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing IT security solutions for vehicles primarily focus on detection and basic prevention of IT security risks, neglecting personal safety and often requiring offline updates, which can render vehicles unusable until risks are mitigated.
Innovation Solution
A method that integrates a detection module to identify attacks, a decision module to assess measures based on personal safety and attack security requirements, and an implementation module to coordinate the necessary actions, ensuring both safety and security are considered during vehicle operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional IT security solutions are used for vehicle detection, then attack detection capability is improved, but personal safety of occupants and road users deteriorates
Solution Approach 1:
The security system is segmented into distinct functional modules: a detection module for identifying attacks, a decision module for evaluating measures based on both attack security and personal safety requirements, and an implementation module for coordinating responses. This segmentation allows specialized handling of personal safety considerations separate from pure attack detection, resolving the contradiction by ensuring detection capabilities are enhanced while personal safety is explicitly protected through dedicated evaluation criteria in the decision module.
2Reliability
If offline updates are performed to mitigate security risks, then attack security is improved, but vehicle availability deteriorates
Solution Approach 1:
The system performs preliminary actions by pre-evaluating multiple security measures and their potential impacts on personal safety and vehicle operation before an attack occurs. The decision module maintains a prepared set of assessed measures that can be quickly implemented when an attack is detected, eliminating the need for offline updates that would interrupt vehicle operation. This allows security mitigation to be executed in real-time without compromising vehicle availability.
Solution Approach 2:
The vehicle security system is designed to be self-service capable, with the decision module autonomously evaluating available measures and selecting appropriate responses based on pre-established personal safety and attack security requirements. This self-service capability eliminates dependency on external offline updates, allowing the system to independently mitigate security risks while maintaining continuous vehicle operation and availability.
3Reliability
If comprehensive security measures are implemented to protect against attacks, then attack security is improved, but system complexity deteriorates
Solution Approach 1:
The decision module serves multiple functions: it evaluates attack detection information, assesses available security measures, considers personal safety requirements, and coordinates implementation decisions. This multi-functionality consolidates what would otherwise require separate complex systems into a single universal module, achieving comprehensive attack security protection while managing system complexity through functional integration rather than proliferation of separate components.
