Vehicle digital key sharing method and system and mobile terminal

Abstract

The invention provides a vehicle digital key sharing method and system and a mobile terminal, and the method comprises the steps: after a first mobile terminal receives the identity information of a vehicle borrowing user who borrows a vehicle and is input by a vehicle owner user, generating first verification information based on the identity information by using a preset algorithm; sending a vehicle lending request carrying the first verification information to a cloud, and enabling the cloud to analyze the first verification information based on the vehicle lending request and then verify the first verification information, and generate a digital key of the vehicle which can be automatically acquired by a second mobile terminal of the vehicle lending user after the first verification information passes the verification. Based on the scheme provided by the invention, the cloud needs to verify the identity of a vehicle owner user, feature exchange, key transmission and verification and session key negotiation are also needed between the second mobile terminal of the vehicle borrowing user and the vehicle, then the vehicle control instruction can be sent, and the security of the digital key is ensured through multi-key encryption and verification.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a method and system for sharing a vehicle digital key, and a mobile terminal. Background technique [0002] With the rapid development of information technology, smart terminals such as mobile phones and tablet computers are becoming more and more popular. And with the continuous improvement of people's needs, more and more functions are integrated in the terminal. For example, the terminal can be used to establish a wireless connection with the vehicle, and then control the vehicle, such as opening the door, opening the window, and so on. [0003] Generally speaking, during the connection and communication process between the terminal and the vehicle, key encryption technology can be used to ensure the security of the communication. The vehicle owner's terminal (for example, a mobile phone) can communicate with the vehicle's terminal, for example, a vehicle-mounted TBOX (T...
