A chaotic secure communication method based on chaos systems partial series parameter estimation

本文提出一种混沌保密通信方法,即混沌系统的部分序列用于混沌系统参数辨识其他序列用于通信保密.利用混沌蚁群优化算法对部分序列混沌系统进行参数辨识,以达到了解混沌系统全部信息的目的.在参数辨识过程中引入参数空间和蚁群空间,通过空间变换函数使参数空间与蚁群空间之间相互变换.文中使用Lorenz系统进行数值试验,其结果验证混沌系统部分序列参数辨识及混沌保密通信的可行性.

We proposed a chaotic secure communication method,namely the partial series of the chaos system for parameter estimation and the other series for secure communications.Parameter estimation could be obtained from the partial series of chaos system with the chaotic ant swarm optimization algorithm,to understand all of the information of the chaos system.In the process of parameter estimation,the introduced parameter space and ant swarm space transformed into each other through space transformation function.Numerical simulation validated the feasibility of the chaos system partial series parameter estimation and the chaotic secure communication method.
