Embodiment Construction

[0035] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0036] See figure 1 , a system for remotely controlling vehicles based on encrypted short messages of the present invention, the system includes a client, a GSM communication module, and a car anti-theft device.

[0037] The client encrypts the short messages, and identifies the sequence of each short message by adding a serial number in the short message. The short message is packaged according to the AT command protocol format, and the content of the control command is included in the short message.

[0038] Except for the serial number of the short message sent by the client for the first time, other serial numbers are the results calculated according to the serial number encryption algorithm based on the previous serial number. The serial number encryption algorithm specifically includes the following steps:

Abstract

A system for remotely controlling vehicles based on encrypted short messages, including: a client for encrypting short messages and sending them to a GSM communication module; a GSM communication module for transmitting short messages and vehicle data and verifying new short messages ; The car anti-theft device is used to collect car data according to the content of the short message, and send the car data to the GSM communication module. The present invention encrypts the short message through the client, and adds a serial number in each short message; the client sends the short message to the GSM communication module through the GSM network, and the GSM communication module encrypts the short message through the serial number and the time stamp Verify, and send the verified SMS to the car anti-theft device. Through the technical scheme of the invention, the vehicle can be remotely controlled and the real-time data of the vehicle can be obtained. The invention checks the short message through the serial number and the time stamp, and can realize a relatively safe and reliable communication based on the unreliable and connectionless short message communication, so that hackers cannot attack or steal the vehicle.

Description

technical field [0001] The invention relates to the field of vehicle control, in particular to a system and method for remotely controlling vehicles based on encrypted short messages. Background technique [0002] At present, the electronic car anti-theft devices on the market can generally realize close control of the car, such as locking, igniting, opening the trunk and so on. However, it can only be controlled at a short distance, and the real-time status of the car cannot be reported remotely, so the application range is limited. [0003] In order to realize long-distance information transmission, the more convenient and common communication method is short message. In the short message communication system, the communication between the user's mobile phone and the base station is encrypted, but the base station and the base station are sent in plain text. And the user's mobile phone is also easy to leak communication data content in the process of using the positionin...
