摘要: 該文在Shannon關(guān)于混亂理論的指導(dǎo)下，在混沌吸引子的多維空間中，利用混沌運(yùn)動的初值敏感性和長期不可預(yù)測性，提出了一種生成密鑰序列的新方案，詳細(xì)地論述了密鑰序列的生成過程；計(jì)算了密鑰空間的大??；對所生成的密鑰序列作了局部隨機(jī)性檢驗(yàn)和復(fù)雜度分析。結(jié)果表明，所生成的密鑰序列適合數(shù)據(jù)加密。

Abstract: Directed by Shannons disorder theory, this paper present a scheme for generating key sequences by using the sensitivity to initial values and the long time unpredictability of chaos motion. The generating scheme and process of the key sequence are described in detail. The size of the key space, randomness testing and linear complexity testing are carefully studied by computer simulation. The results indicate that the key sequences satisfy the requirements of data encrypting. -
