基于Chen混沌系统的数字信息传输

针对经典Chen混沌系统,文章对系统中的参数a进行了调制,使驱动系统中的参数a随数字信息的变化而变化,发送端将随发送的不同数字信息而产生不同的动力学行为,从而完成对数字信息的加密传送,接收端采用Chen混沌系统及所设计的控制器,在控制器的控制下对数字信息进行解密,完成数字信息的加密传输。

Aiming at the classical Chen chaotic system, this paper modulates the parameter a in the system, so that the parameter a in the drive system changes with the change of digital information, and the sender will produce different dynamic behavior with the different digital information sent, in order to complete the encryption of digital information transmission. The receiver uses Chen chaotic system and the designed controller, decrypt the digital informationunder the control of the controller and complete the encrypted transmission of digital information.
