Embodiment Construction

[0017] The method of the present invention will be further described below through specific embodiments in conjunction with the accompanying drawings.

[0018] The hardware basis of the technical solution adopted by the present invention to solve the technical problem is: the hand-held remote controller of the car and the matching remote control base station installed on the car body, both of which have the ability to transmit and receive radio wave signals at the same time.

[0019] figure 1 It is a work flow chart of the handheld remote controller in the present invention, and the concrete steps are as follows:

[0020] 1) After a certain function button is pressed on the hand-held remote control of the car, it will send a radio frequency signal for a certain period of time. The radio frequency signal format includes a rolling code and an operation code. The rolling code is used to match the communication identity between the remote control base station and the handheld rem...

Abstract

The invention discloses an automobile remote control radio frequency encryption matching method with high anti-theft performance. The method is implemented on the basis of an automobile handheld remote controller and a remote control drill base installed on an automobile body matched with the automobile handheld remote controller, and the communication matching uniqueness of the handheld remote controller and the automobile body drill base through an identification code. By adoption of the automobile remote control radio frequency encryption matching method disclosed by the invention, the anti-wiretapping, anti-replication and anti-cracking performance of the automobile remote controller, even f the criminals master the encryption algorithm and the initial values of the parameters of the automobile remote controller from the production source, the uniqueness and the security of the automobile remote controller can also be guaranteed by the method provided by the invention.

Description

technical field [0001] The invention relates to a wireless remote control system for a car, in particular to an improved radio frequency encryption matching method for a car remote control. Background technique [0002] Most of the cars currently on the market are equipped with radio frequency remote controls, which can execute commands such as locking, unlocking, and opening doors for the car. While the wireless radio frequency remote control brings convenience, it also increases the risk of car theft, because criminals can use technical means to intercept the sending and receiving signals of the remote control for decryption, and then invade the remote control door lock system of the car. [0003] At the Usenix Security Conference in Austin in August 2016, researchers from the University of Birmingham in the United Kingdom and the German engineering company Kasper&Oswald disclosed the obvious loopholes in the current car remote control door lock system, involving many car ...
