【Abstract】 In this paper, a multistage chaotic system for secure comm unication is proposed. The method improves greatly the secure property and the bandwidth of the chaotic secure communication system. The exa mple that we give demonstrates the efficiency of the method. At last, in view of the practical application, the problem which need further r esearch and solve is discussed.更多还原
