Safety certification system for automobile theft prevention

Abstract

The invention provides a safety certification system for automobile theft prevention, which comprises a remote control key, a safety control module and an engine control module, wherein the safety certification is carried out between the remote control key and the safety control module based on AES128; the safety certification is carried out between the safety control module and the engine control module based on AES128; and when the certification between the engine control module and the safety control module is passed, the engine control module sends an ignition control signal and a fuel injection control signal to an engine. The system has the advantages of low dependency on theft prevention controller suppliers or theft prevention chip suppliers, strong safety and the like, and can be widely applied in the automobile safety field.

Description

technical field [0001] The invention relates to safety authentication technology, in particular to an automobile anti-theft safety authentication system. Background technique [0002] In recent years, with the development of the economy, automobiles have become a necessity in production and life, and automobile safety issues have become extremely important. At present, the anti-theft method in the automobile anti-theft security authentication system generally adopts the anti-theft method provided by the anti-theft controller supplier or the anti-theft chip supplier. However, the anti-theft methods provided by anti-theft controller suppliers or anti-theft chip suppliers are uneven, which makes the car anti-theft safety problem have many hidden dangers; Shorter, generally using a 64-bit key code. Based on the above situation, the current car anti-theft has been cracked and the security is low. [0003] Advanced Encryption Standard (AES) is a block encryption standard adopte...
