| 摘 要： | 该文从研究混沌加密系统输出信号的保密性能角度出发，对典型的Lorenz系统进行了分析。研究发现，大采样间隔对增强混沌系统的保密性能有重要影响。然后用Volterra-wiener-Korengerg(VwK)模型非线性检验方法对上述结论进行了检验，最后通过计算机仿真得出相同的结论。

| 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. |
