为了便于蔡氏混沌电路的集成，设计了具有模拟电感的蔡氏混沌电路。在此电路基础上，进一步设计了混沌保密通信电路，并进行了仿真研究。结果表明，合适参数的发送信号在该混沌保密通信电路中能被很好地掩盖，也很难被窃听，发送信号和保密通信电路解调出来的信号是一致的，说明该通信电路具有很好的保密性能。但是当发送信号的幅度和频率超过一定值时，该混沌保密通信电路几乎不能实现对发送信号的保密。

The simulated inductor is used in Chua's chaotic circuit for convenient integration of the circuit .Based on modified Chua's circuit ,the chaotic secure communication circuit is designed and simulated .The simulation results show the modified Chua's circuit chaotic secure communication system can achieve secure communication , but it can hardly achieve secure communication when the amplitude and frequency of the sending signal exceeds a certain value .
