| 摘 要： | 提出了一种新的基于混沌掩蔽的保密通信方法．在发送端，信息序列在与混沌掩蔽序列相加的同时还介入到该掩蔽序列的发生之中．在接受端，一个与发送端具有相同非线性函数形式的非动力学系统被用来从接受信号中提取混沌掩蔽序列，然后再与接受信号相减以恢复信息序列．理论分析和计算机模拟表明，该方法保密性好、可靠性高且实现容易．

| Abstract: | A novel secure communication approach via chaotic masking is proposed. At the transmitter, a message sequence is added to a chaotic masking sequence and is,at the same time, also involved in the generation of the masking sequence. At the receiver, a non dynamical system which adopts the same nonlinear functions as what is adopted at transmitter is used to retrieve the masking sequence from the received signal and then the message sequence is recovered through subtraction. The results of the theoretical analysis and computer simulation show that the chaotic digital secure communication system presented in this paper has the fine security, high reliability and can be implemented easily. |
