| Abstract: | Based on the principle and characteristic of Arnold transformation,two kinds of scrambling-resumption methods are studied.By using simulation,their efficiencies are compared.Taking reducing the scrambling-resumption time into account,this paper puts forward an optimized method by synthesizing them,which improves the scrambling-resumption efficiency at certain extent. |
