基于时空混沌同步及瞬间转换熵解调的安全通信
首发时间:2010-01-06
摘要:本文以单向耦合映像格子(OCML)为时空混沌模型,实现了单路驱动的时空混沌同步。并在此基础上设计了一个安全通信系统,该系统将与发送端时空混沌系统中节点有驱动关系的混沌序列发送至接收端,并在接收端引入瞬间转换熵(TTE)算法,利用接收端同步时空混沌系统与传输混沌序列的相互驱动关系解调出原始传输信息。本文仿真实现了该系统的通信过程,并对其安全性能进行简单分析。

Secure Communication via Spatiotemporal Chaos Synchronization and Temporal Transfer Entropy Demodulation
Abstract:This paper designs a secure communication system via the spatiotemporal synchronization of one-way coupled map lattice (OCML) driven by single signal. This system transmits a chaotic sequence to the receiver system, and this sequence has driving relationship with several different nodes of the OCML in the transmitter. In the receiver system, we adopt the TTE algorithm to recover the original information by using the interaction between the transmitted chaotic sequence and the OCML in receiver system. This paper also achieves the communication process simulation, and analyses its safety performance.
