Vehicle Service Enrollment via Server Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for controlling vehicle functions, such as unlocking doors, via a user terminal like a cellphone lack robust authentication mechanisms, potentially allowing unauthorized access.
Innovation Solution
A method involving communication of user and vehicle identifiers to a server for authentication, using cryptographic keys and mutual authentication between the server and vehicle's electronic control unit, along with detection of user actions on physical objects linked to the vehicle, to securely enroll users in a service and distribute virtual keys.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a user terminal is used to control vehicle functions, then ease of operation is improved, but reliability of access control deteriorates due to lack of robust authentication
Solution Approach 1:
The patent implements preliminary authentication actions before granting access to vehicle functions. The server performs mutual authentication with the vehicle's electronic control unit and detects user actions on physical objects before distributing the virtual key, ensuring that only authorized users can control vehicle functions through their user terminal
Solution Approach 2:
The patent introduces a server as an intermediary between the user terminal and the vehicle's electronic control unit. This server mediates the authentication process, verifies the vehicle's identity, detects user actions, and distributes virtual keys, thereby enhancing the reliability of access control while maintaining ease of operation through the user terminal
2Ease of operation
If virtual keys are distributed to user terminals, then ease of operation is improved, but security against unauthorized access deteriorates without proper authentication
Solution Approach 1:
The patent performs preliminary authentication and user action detection before distributing virtual keys to user terminals. The server verifies the vehicle's identity through mutual authentication and confirms the user's identity by detecting actions on physical objects, ensuring that only authorized users receive virtual keys and can control vehicle functions
Solution Approach 2:
The patent implements feedback mechanisms where the server detects user actions on physical objects and uses this information to verify user identity before key distribution. The mutual authentication process also provides feedback to confirm the vehicle's authenticity, thereby preventing unauthorized access while maintaining ease of operation

AI summary
A method for signing up a user to a service for controlling at least one functionality in a vehicle (10) by means of a user terminal (20) comprises the following steps: —communicating a user identifier and an identifier associated with the vehicle (10) to a server (50); —having the server (50) authenticate an electronics unit (11) of the vehicle (10); —in the event of successful authentication, registering the user identifier and the identifier associated with the vehicle (10) in association with one another in the server (50).
