摘　　要：提出一种基于分段映射的保密通信算法.算法中使用两个混沌系统,运用一个混沌系统所输出的混沌符号序列跟踪预定的要传输的信息符号序列;运用从另一个混沌系统中所提供的二进制序列,采用混沌掩码技术对要传输的信息进行加密.理论分析和实验结果表明,该算法运算速度快、容易实现且安全性高,具有很强的实用价值.A secure communication algorithm based on piecewise liner chaotic map is proposed. Two chaotic maps are used in this algorithm, with a symbolic sequence generated by a chaotic map the message sequence is tracked, employing the chaotic masking technique the message for transmitted is encrypted with a binary sequence extracted from another chaotic map. The theoretic and experience results stated that the proposed algorithm has many properties such as high speed and easy implementing and high security and it is suitable for practical use in the secure communication.
