| 摘 要： | 混沌连续值序列经离散化后得到二进制序列，离散化方法对混沌序列的随机特性具有重要影响。首先证明了两种常用的离散化方法是等效的。然后，利用NIST测试组件中的五项统计测试对Logistic、Cubic和Chebyshev混沌映射生成的序列进行了随机性检验，并得出了一些相关结论。

| Abstract: | Outputs of chaotic maps are converted to binary sequences by discretization.Randomness of chaotic binary sequences is greatly influenced by discretization methods.Two kinds of discretization methods are proved to be equivalent.Then, five statistics tests in the NIST test suite are chosen to check the randomness of Logistic,Cubic,and Chebyshev chaotic sequences.Finally,some conclusions are drawn. |
