Remote Vehicle Start Verification via Server and Telematics Box
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional car key systems are inconvenient and prone to security issues, as security information for starting a vehicle is transparently transmitted, making it vulnerable to malicious starts when using mobile terminals for vehicle initiation via NFC or Bluetooth.
Innovation Solution
A method where a server obtains and transmits first and second security information to a mobile terminal and telematics box respectively through secure protocols, ensuring verification of vehicle start instructions without transparent transmission, thereby reducing the risk of malicious starts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If NFC or Bluetooth is used for communication between mobile terminal and telematics box, then vehicle starting function is enabled, but security information is transparently transmitted and vulnerable to leakage
Solution Approach 1:
A server is introduced as an intermediary between the mobile terminal and telematics box. The server receives the vehicle starting request from the mobile terminal, verifies it using security information stored on the server, and then instructs the telematics box to start the vehicle. This mediator architecture prevents direct transparent transmission of security information between terminal and vehicle, as the server holds and manages the security credentials centrally.
Solution Approach 2:
The security information (vehicle starting key) is extracted from the telematics box and stored on the remote server instead. When a starting request is made, the server retrieves and uses this extracted security information for verification without transmitting it to the mobile terminal or telematics box during the starting process, thus preventing leakage.
2Ease of operation
If conventional car key is used, then vehicle starting is simple, but key is prone to get lost and inconvenient in daily use
Solution Approach 1:
The physical car key is replaced by a virtual copy in the form of a software application on the mobile terminal. The server stores multiple copies of the vehicle starting key and can issue them to multiple mobile terminals, enabling the user to start the vehicle using their smartphone without carrying a physical key, thus eliminating loss risk while maintaining starting functionality.
3Reliability
If security information is transmitted from server to mobile terminal and telematics box, then verification capability is enabled, but transmission security may be compromised
Solution Approach 1:
The security information is transmitted and stored on the server in advance, before any vehicle starting operation. The server pre-establishes secure communication channels with both the mobile terminal and telematics box, and distributes verification credentials beforehand. This preliminary setup allows subsequent starting operations to use these pre-established secure channels rather than transmitting sensitive data repeatedly over potentially insecure channels.
Data Source
AI summary
A method for starting a vehicle and a related device are provided. The method includes: a server sends first security information and second security information to a mobile terminal and a telematics box respectively through an encrypted secure transmission channel or an encrypted secure transmission protocol, so that the telematics box can verify, by using the first security information and the second security information, a vehicle start instruction sent by the mobile terminal. When the verification succeeds, the telematics box controls the vehicle to start. According to the application, plaintext transmission of the security information between the mobile terminal and the telematics box is avoided, thereby avoiding leakage of the security information, and reducing a risk that the vehicle is maliciously started. In addition, a transmission process of the security information may not be restricted by a distance between the vehicle and the mobile terminal.
