对离散时间动力学系统逻辑影射进行变换,使其在一定精度下产生数字混沌序列,采用该数字混沌序列作为密码,构造了语音保密通信系统,并运用单片机实现了该系统的硬件实验。
The logic projection of discrete-time dynamic system is transformed to generate digital chaos sequence with a certain precision. The digital chaotic sequence is used as a password to construct a speech secure communication system. The hardware experiment of the system is implemented by using a single chip microcomputer.
