摘　　要：给出性能较好的混沌序列生成器,并将其生成二值序列的方法进行了改进。在此,将几种常用的混沌序列生成器进行比较分析。Logistic映射和Hybrid映射是两种较好的混沌映射。混沌序列具有易生成性,对初始条件强敏感性,可完全重现性等特点,基于以上特性,很多的图像置乱加密算法都采用了混沌序列。Some chaos sequence generators with better performance is introduced and the method of binary sequence generated by the chaotic mapping is improved.Some common used chaos sequence generators are compared and analysed.Both Logistic mapping and Hybrid mapping are the better ones.Chaos sequence has the features of feasible generation,sensitivity to initial conditions and complete reappearance.Many image scrambling encryption arithmatics use the chaos sequence based on the above features.

关 键 词：混沌序列 离散化 敏感性 混沌序列
