摘要
本文利用多次选代混沌映射来设计非线性前馈型流密码，在理想实现条件下，混沌前馈型流密码不仅对混沌密码参数和驱动信号的变化十分敏感而且具有均衡的分布特性．本文还考察了在有限精度实现下。
In this paper,a class of multiple-iterated chaotic system is used to design nonlinear feed forward stream cipher. When analogue chaotic system is considered,the chaotic stream cipher is proved to be balanced and very sensitive to its parameter and the drive signal. The finite precision problem is also investigated and two resolving methods are proposed.
