| Abstract: | In secure communications,it is difficult to solve some existing problems of conventional synchronization between two continuous flow chaotic systems.Therefore,in this paper the theorems on synchronization based on digital flow chaos in secure communications are presented and a scheme of secure speech communication are presented and realized.In the scheme a new synchronic method--cycles and interval pulse drive is developed and realized.Experimental results show it is feasible. |

| Keywords: | digital flow chaos synchronization cycles and interval pulses drive synchronization noise |
