Vehicle Anti-Theft Authentication for Staged Function Activation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle anti-theft technologies are inadequate as they do not prevent unauthorized entry or driving of vehicles when parked in remote areas, as they rely primarily on alarms and do not ensure secure activation of vehicle functions.
Innovation Solution
A multi-step authentication method involving key information matching, primary anti-theft authentication between a vehicle body controller and a gateway for basic function activation, and secondary anti-theft authentication between the gateway and a power controller for driving function activation, using one-way or two-way authentication processes, with sensors detecting driver presence as a preset condition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional anti-theft technology using alarms is used, then the vehicle can alert when approached, but it cannot prevent unauthorized entry or starting when parked in remote areas
Solution Approach 1:
The authentication system is divided into multiple independent authentication stages: first authentication between the key and vehicle body controller, second authentication between the vehicle body controller and gateway, and third authentication between the gateway and power controller. Each stage verifies different information (key information, first authentication information, second authentication information) to progressively activate vehicle functions, ensuring that no single point of failure compromises overall security.
2Reliability
If multi-step authentication is implemented, then vehicle security is improved, but the authentication process becomes more complex
Solution Approach 1:
The system performs preliminary authentication actions in advance by first verifying key information before activating basic vehicle functions, and then performing additional authentication before enabling driving functions. This staged approach ensures that even if one authentication layer is compromised, the vehicle remains protected through subsequent authentication barriers.
3Ease of operation
If basic functions are activated after first authentication, then vehicle usability is improved, but the risk of unauthorized driving activation increases
Solution Approach 1:
The vehicle's functionality is segmented into two distinct activation levels: basic functions (activated after second authentication) and driving functions (activated after third authentication). This segmentation allows legitimate users to access basic functions while requiring an additional authentication layer for driving functions, thereby balancing usability with security against unauthorized vehicle operation.

AI summary
The disclosure relates to the field of vehicles, and particularly, to a method and system for vehicle anti-theft authentication, a storage medium, and a vehicle including the system. The method includes the following steps: determining whether key information in a vehicle key matches preset information; performing primary anti-theft authentication between a vehicle body controller and a gateway in a case of matching, to determine whether to activate a vehicle basic function; and performing secondary anti-theft authentication between the gateway and a power controller in a case of meeting a preset condition, to determine whether to activate a vehicle driving function, where the preset condition includes that the vehicle basic function has been activated.
