摘要
近年来,利用混沌特性进行数据加密得到了较多的研究,超混沌映射参数的不同取值直接影响超混沌映射所产生序列密码的复杂性.以广义Henon映射作为实验对象,以MATLAB7.0为实验平台,分析映射初值及参数在什么范围内取值可以产生可实际应用的超混沌序列及其随机特性、自相关特性、互相关特性、平衡性及游程的变化,为工程实际应用时选择参数提供参考.
Recent study has revealed that the hyper chaos mapping parameter and initial value has impact on the complexity of the stream cipher produced by hyper chaos mapping. By using generalized Henon mapping as experimental objective and using MATLAB 7.0 as experiment platform, The authors analyze the mapping initial value and in what range it is possibe for the parameter to take value so as to be able to produce the hyper chaos stream of practical application, and analyze its randomness, correlated characteristic, and runs change, so that a reference could be provided for the parameter choice of practical project application.
