摘要
设计了基于混沌双重加密的混沌同步保密通信方案,用以改善保密通信系统的安全性.一级加密采用了具有2种反馈的同步混沌系统,二级加密采用了超混沌系统.仿真结果成功地还原了原文信号,证明所设计系统能够更有效的避免现有的基于混沌保密通信破译方法的攻击.
A new method based on two-level chaotic synchronization scheme is used to realize secure communication.The first level of chaotic synchronization scheme is a double feedback synchronization chaotic systems,the second level is a hyperchaos system.Simulation experiment is carried out by Simulink,and the original signal is reproduced.The system can avoid attacks based on the chaos security deciphering principle effectivel.
