Embodiment Construction

[0110] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0111] figure 1 A schematic diagram of an implementation environment provided by an embodiment of the present invention. Such as figure 1 As shown, the vehicle 100 is equipped with a smart key base station and equipped with 5 to 6 low frequency antennas. Generally, one low-frequency antenna is installed on the left side door and the right side door of the vehicle 100, two antennas are installed inside the vehicle 100, one antenna is installed on the trunk, and one antenna is installed on the rear bumper. The vehicle 100 may use a low-frequency alternating voltage to drive a resonant circuit composed of an antenna and a capacitor, and the low-frequency reso...

Abstract

The invention aims at providing a vehicle anti-theft method and device and a vehicle, which are used for solving a technical problem that a vehicle anti-theft system in the prior art is easy to attack. The vehicle anti-theft method comprises the steps of transmitting a broadcast message including an original identification code; receiving a request message, which is transmitted by an initiator andused for requesting to release a vehicle anti-theft state, wherein the request message includes authentication data and the authentication data are generated by the initiator according to the original identification code; deleting data, in a preset flag bit, in the authentication data as induced data and decrypting the authentication data after the induced data are deleted; and when the decryption is successful and the decrypted data are obtained, comparing the decrypted data with the original identification code and determining whether the vehicle anti-theft state is released or not according to a comparison result.

Description

technical field [0001] The present disclosure relates to the field of vehicle security, in particular, to a vehicle anti-theft method, device and vehicle. Background technique [0002] With the vigorous development of the automobile industry and the continuous improvement of electronic technology, vehicle anti-theft has been gradually upgraded from traditional mechanical anti-theft methods to electronic technology-based anti-theft methods, which also provides opportunities for criminals to use electronic technology to crack car anti-theft systems. . [0003] The prior art adopts radio frequency technology to realize keyless starting of the vehicle. In a specific implementation, the user enters the vehicle identification range with a smart key, and the vehicle performs identity authentication on the smart key, and after the verification is successful, the vehicle anti-theft system is automatically released, and the vehicle is started when the user touches a corresponding but...
