Vehicle Access Authentication Using Pre-Connection Authorization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern vehicles face increased security risks due to expanded access to sensitive information and systems via OBD ports, including wireless connections, which traditional security mechanisms fail to adequately protect against unauthorized access and potential attacks.
Innovation Solution
Implementing a remote authentication system where a connection request is verified by an authorization server, generating an authorization certificate, and only activating the vehicle communication system after successful authentication, ensuring a zero-trust relationship until verification is complete.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional OBD port security is used (physical access prevention), then diagnostic information can be accessed, but security against unauthorized access to sensitive vehicle systems is insufficient
Solution Approach 1:
The system performs preliminary authentication of the remote device before establishing any communication connection. The authorization server verifies credentials and generates authorization certificates in advance, ensuring that only authenticated devices can access the vehicle communication system, thus preventing unauthorized access before it can occur
Solution Approach 2:
An authorization server is introduced as an intermediary between the remote device and the vehicle communication system. This mediator verifies authentication credentials, manages authorization certificates, and controls access permissions, thereby providing a security layer that protects sensitive vehicle systems while allowing legitimate diagnostic access
2Ease of operation
If wireless OTA access is enabled, then remote access convenience is improved, but security risks from unauthorized access increase
Solution Approach 1:
The system requires preliminary authentication through an authorization server before enabling any wireless communication. The server verifies device credentials and issues authorization certificates in advance, ensuring that wireless access is granted only to authenticated devices, thus maintaining convenience while preventing unauthorized access
Solution Approach 2:
The authorization server acts as a security intermediary that manages all wireless access requests. It verifies authentication credentials, controls connection permissions, and monitors communication sessions, thereby enabling convenient remote access while systematically preventing security risks from unauthorized devices
3Speed
If authentication is performed after connection establishment, then connection speed is fast, but security against pre-authentication attacks is compromised
Solution Approach 1:
The system performs authentication actions before the communication connection is fully established. The authorization server verifies credentials and generates authorization certificates in advance, so that by the time the connection is active, authentication is already complete, preventing any pre-authentication attacks while maintaining fast connection speeds

AI summary
In some embodiments, apparatuses and methods are provided herein useful to allowing a connection to a vehicle. In some implementations, a method comprises receiving, by an authorization server from a remote device, a connection request for the vehicle, verifying, by the authorization server, the connection request, in response to verifying the connection request, generating by the authorization server, an authorization certificate, transmitting, by the authorization server, the authorization certificate, receiving, by the vehicle, the authorization certificate, authenticating, by the vehicle, the authorization certificate, and in response to the authenticating the authorization certificate, activating, by the vehicle, a vehicle communication system.
