一种实用的混沌保密编码方法

A Practical Method of Chaos Secret Coding

  • 摘要: 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。使用数字可编程芯片TMS320VC5402实现了实时保密编码,并对混沌符号密钥的相似性作了分析。研究表明,该方法在实际应用中具有推广价值。

     

    Abstract: 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. Then, we realize the real-time secret coding on the digital chip TMS320VC5402 and analyze the similarity of symbol secret keys. The results show that this method has extended value for the practical usage.
