Abstract In this paper, the encryption property of the chaotic system in terms of the techniques developed in the analysis of chaotic time series is studied. Then, the typical Lorenz system is analyzed. It is found that the larger sampling interval is of huge help for improving the encryption property. The VWK(Volterra-Wiener-Korengerg) method is used to analyze and test. Finally, simulation on the computer gets the same result.
