Based on the foundation theory of applied symbolic dynamics, we get a practical method of chaos secret coding, i.e. use the strange attractor of logistic map to produce the symbol secret key to modulate the source code.
基于实用符号动力学的基础理论，提出了一种实用的混沌保密编码方法，该方法借助于单峰的logistic映射处于混沌吸引子状态时产生的符号序列作为密钥，对信源编码信号进行加密。
