| 摘 要： | 同步电路是实现保密通信的前提和基础,为了将混沌同步控制应用于保密通信,本文对给出的时滞Lorenz混沌系统设计了相应的同步电路.首先,运用数值仿真对系统的分岔图、相图、功率谱、Poincare映射进行分析.其次,给出了时滞Lorenz混沌系统的同步电路,并推导出各元件的有效值,在此电路的基础上利用电路仿真软件Electronic Workbench(EWB)进行了仿真实验.整个电路结构简单,实现容易,能够通过调节部分元件有效值获得丰富的混沌信号和较好的同步性能.最后借助于所研究的时滞Lorenz混沌系统的同步电路,利用混沌掩盖技术实现图像保密传输,并能正确有效地恢复出原文图像.
