Embodiment 1

[0087] The predetermined encryption algorithm is a symmetric encryption algorithm. And, in the first embodiment, it is described by taking the vehicle as an example to determine the first authentication password, encrypt the first authentication password based on the session key, and then send it to the mobile terminal. specific, figure 2 A flow chart of a binding method between a vehicle and a mobile terminal provided in Embodiment 1 of the present invention, as shown in figure 2 As shown, the binding method of the vehicle and the mobile terminal includes:

[0088] Step 201. Provide a vehicle, and the vehicle communicates with a mobile terminal in near field.

[0089] In step 202, the vehicle sets a session key based on a predetermined cryptographic algorithm.

[0090] Wherein, when the vehicle sets the session key, the mobile terminal will also set the session key. Specifically, the method for setting the session key by the vehicle and the mobile terminal may include b...

Embodiment 2

[0118] The predetermined encryption algorithm is a symmetric encryption algorithm. And, the difference between the second embodiment and the first embodiment above is that in the second embodiment, the first authentication password is not determined by the vehicle, but the first authentication password is determined by the mobile terminal, and the vehicle receives the first authentication password sent by the mobile terminal. encrypting the first authentication password, and performing a decryption operation on the encrypted first authentication password based on the session key to obtain the first authentication password. specific, image 3 A flow chart of a binding method between a vehicle and a mobile terminal provided in Embodiment 2 of the present invention, as shown in image 3 As shown, the binding method of the vehicle and the mobile terminal includes:

[0119] Step 301. Provide a vehicle, and the vehicle communicates with the mobile terminal in near field.

Embodiment 3

[0129] The predetermined encryption algorithm includes an asymmetric encryption algorithm. And, in the third embodiment, instead of the vehicle determining the first authentication password, the mobile terminal determines the first authentication password, and the vehicle receives the encrypted first authentication password sent by the mobile terminal, and based on the session key The first decryption operation is performed on the encrypted first authentication password to obtain the first authentication password as an example for description. Figure 4 It is a flow chart of a binding method between a vehicle and a mobile terminal provided in Embodiment 3 of the present invention, as shown in Figure 4 As shown, the method includes:

[0130] Step 401. Provide a vehicle, and the vehicle communicates with a mobile terminal in near field.

[0131] Step 402, the vehicle sets a session key based on a predetermined cryptographic algorithm.

[0132] Wherein, when the vehicle sets ...

Abstract

The invention provides a vehicle and mobile terminal binding method and system, and the method comprises the steps: a vehicle is provided, which is in near field communication with a mobile terminal; the vehicle sets a session key based on a predetermined cryptographic algorithm; the vehicle determines a first authentication password, encrypts the first authentication password by using the session key, and sends the encrypted first authentication password to the mobile terminal; or, the vehicle receives an encrypted first authentication password sent by the mobile terminal, and decrypts the encrypted first authentication password by using the session key to obtain the first authentication password; and the vehicle performs mutual trust authentication with the mobile terminal based on the first authentication password, and performs binding operation after the authentication is passed. The vehicle and mobile terminal binding method and system provided by the invention are wide in application range and high in safety.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a method and system for binding a vehicle and a mobile terminal. Background technique [0002] In the field of automobile technology, the mobile terminal is usually bound to the vehicle, and the vehicle is controlled through the mobile terminal, so as to control the vehicle more conveniently and improve user experience. [0003] In the related art, the binding method between a vehicle and a mobile terminal is: the cloud platform sends authentication passwords to the mobile terminal and the vehicle to be bound respectively, and then the mobile terminal and the vehicle to be bound perform authentication based on the authentication password. Authentication, when the authentication is passed, the two are bound. [0004] However, in the related art, the premise of the execution of the binding method needs to have a network signal, so it has limitations and a small scope of applic...
