摘要
给出了一种便于集成的改进型Chua电路,构造出一种具有一定鲁棒性、抗干扰等特性的驱动-响应式混沌同步系统,研究发现此混沌同步系统具有自保持特性,并给出研究结果。利用此特性,解决了目前如何同时在同一信道中传输混沌同步控制信号和密文信号的关键性问题,实验证明了此方法的可行性,为混沌在保密通信的实际应用奠定了基础。
Chua＇s circuit, which is improved to integrate conveniently, is presented. A driveresponse chaotic synchronization system is constructed, which possesses to a certainly stability, resisting-disturbance and so on, by means of research, it can be concluded that the chaotic synchronization system is provided with the characteristic of chaos synchronization self-maintenance, and the research results are also presented. Utilizing the characteristic, the critical problem of how to simultaneously transmit the controlling signal of chaotic synchronization and the secret signal at a channel can be solved. The experiment result provides the foundation of putting chaos into practice application to secret communication .
