Vehicle Security Strategy for External Intrusion Blocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle connectivity systems lack effective security measures to prevent external intrusions, which can lead to malfunctions or personal information leakage when unauthenticated external apparatuses or data flow into the vehicle.
Innovation Solution
A security strategy apparatus comprising a communication circuit, power controller, and control circuit that detects and blocks unauthenticated external apparatuses or data connections by restricting vehicle functions and power supply, determining the level of blocking based on the characteristics of connected devices or data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If connectivity service is provided in vehicle, then convenience to driver is improved, but security vulnerability increases
Solution Approach 1:
The system performs preliminary authentication and registration checks before allowing external apparatuses to connect to the vehicle. The control circuit verifies whether connecting devices are authenticated or registered in advance, and only permits connections from authorized devices, thereby preventing security vulnerabilities before they can affect the system.
2Adaptability or versatility
If external apparatus is connected to vehicle, then functionality is improved, but security risk increases
Solution Approach 1:
The control circuit acts as an intermediary between external apparatuses and the vehicle's internal systems. It mediates connection requests by verifying authentication status and implementing blocking actions when unauthenticated devices attempt to connect, thereby allowing functionality from trusted sources while blocking security risks.
Solution Approach 2:
The system applies different connection policies to different external apparatuses based on their authentication status. Authenticated devices are granted appropriate access levels while unauthenticated devices are blocked, creating localized security measures tailored to each connection attempt rather than a uniform approach.
3Reliability
If security blocking is implemented, then security is improved, but system complexity increases
Solution Approach 1:
The control circuit automatically performs authentication verification and blocking actions without requiring manual intervention. The system self-manages security by detecting unauthenticated connections and autonomously implementing blocking measures, which maintains security while minimizing the operational complexity for users.

AI summary
A security strategy providing apparatus of a vehicle includes a communication circuit, a power controller, and at least one control circuit electrically connected to the communication circuit and the power controller. The at least one control circuit is configured to detect a connection of an external apparatus or an inflow of external data, and to block at least part of a function provided by the vehicle, at least part of power supplied by the power controller, or the at least part of the function and the at least part of the power, based on a detection result of the connection of the external apparatus or the inflow of the external data.
