Vehicle Gateway Authentication for External Controllers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control systems face challenges in verifying external electronic devices, particularly when controllers do not follow the OEM controller access policy, requiring separate authentication certificates.
Innovation Solution
A vehicle control device and system that determine whether a controller follows an OEM access policy using authentication information, and comprehensively manage OEM and controller-specific authentication certificates to facilitate access and routing between external devices and controllers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the vehicle control system uses separate authentication certificates for each controller type (OEM and non-OEM), then authentication coverage is improved, but system complexity increases
Solution Approach 1:
The gateway is designed to perform multiple authentication functions using a single authentication certificate. It can verify both OEM controllers (following OEM access policy) and non-OEM controllers (not following OEM access policy) through the same certificate, eliminating the need for separate authentication mechanisms for different controller types.
Solution Approach 2:
Instead of requiring different authentication certificates for different controller types, the system inverts the approach by using a single authentication certificate that works for all controllers. The gateway determines the appropriate verification method based on the controller's access policy compliance, rather than requiring pre-configured different certificates.
2Reliability
If the system requires authentication certificate verification for all controllers, then security is improved, but processing time increases
Solution Approach 1:
The gateway performs preliminary determination of whether a controller follows the OEM access policy before initiating full authentication certificate verification. This preliminary check allows the system to prepare the appropriate verification path in advance, reducing actual processing time during the authentication process.
Solution Approach 2:
The authentication verification process is made dynamic and adaptive. The gateway adjusts the verification method based on the controller's characteristics (OEM or non-OEM access policy compliance), applying different verification approaches as needed rather than using a fixed, time-consuming process for all controllers.

AI summary
A vehicle control device, a vehicle control system, and a vehicle control method are provided. The vehicle control device includes a processor and a memory for storing instructions. The processor receives a request for accessing a controller from an external electronic device configured to access the controller. The processor determines whether to perform verification for the external electronic device by means of the controller, using authentication information about the controller. Based on the determination to perform the verification, the processor requests an authentication certificate corresponding to the controller from the external electronic device, transmits the authentication certificate to the controller, and sets routing between the external electronic device and the controller, based on completion of verification for the authentication certificate, which is performed by the controller.
