Vehicle-Device Pairing Through Server-Mediated Preliminary Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle and device pairing processes require multiple authentication steps, including digital key validation, which can be cumbersome and inefficient, especially in scenarios where quick and seamless communication is desired.
Innovation Solution
A method and system for pre-pairing vehicles and devices using a server that receives and processes vehicle and device data, enabling a single authentication process and allowing automatic pairing when devices are within a predefined proximity, utilizing a unique identifier for secure communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple authentication steps are used for vehicle-device pairing, then security is improved, but pairing time and complexity increase
Solution Approach 1:
The system performs preliminary authentication by having the server store device information and generate unique identifiers in advance. When a device approaches the vehicle, the pairing is expedited by matching the pre-stored device ID with the approaching device, eliminating the need for multiple real-time authentication steps while maintaining security.
2Reliability
If multiple authentication steps are used for vehicle-device pairing, then security is improved, but operation complexity increases
Solution Approach 1:
The system enables self-service pairing where the vehicle and device automatically authenticate each other using pre-stored information and unique identifiers. The user simply needs to bring the device near the vehicle, and the system handles the authentication process automatically without requiring manual intervention or complex user actions.
3Speed
If device information is stored on the vehicle, then pairing speed is improved, but security risk from RF eavesdropping increases
Solution Approach 1:
The system introduces a server as an intermediary that securely stores device information and generates unique identifiers. The vehicle stores only the unique identifier, not the full device information. During pairing, the server mediates the authentication process by verifying the device ID against stored information, enabling fast pairing while maintaining security through centralized secure storage and mediation.
Data Source
AI summary
An example operation includes one or more of receiving, by a server, vehicle identification data from at least two components in a vehicle and device data from a device associated with the vehicle, sending, by the server, the vehicle identification data to the device and the device data to the at least two components in the vehicle, and pre-pairing the vehicle and the device, based on the sending.
