【摘要】：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.
[Abstract]:In this paper, a chaotic secure communication method is proposed, in which the partial sequences of chaotic systems are used to identify the parameters of chaotic systems and other sequences are used for communication secrecy. The chaotic ant colony optimization (ACO) algorithm is used to identify the parameters of partial sequence chaotic systems in order to understand all the information of chaotic systems. Parameter space and ant colony space are introduced in the process of parameter identification. The parameter space and ant colony space are transformed by space transformation function. In this paper, the numerical experiments of Lorenz system are carried out, and the results verify the feasibility of partial sequence parameter identification and chaotic secure communication of chaotic system.
