用符号动力学方法实现传输信号(文字、图像)的混沌保密。介绍符号动力学的基本知识,并用Logistic映射推广出一种密码流算法,对信号进行混沌编码和解码。
Symbolic dynamics is used to achieve the chaotic security of transmitted signals (texts, images). Introduce the basic knowledge of symbolic dynamics, and use Logistic mapping to popularize a cipher flow algorithm to chaos encode and decode the signal.
