摘要
本文针对有限精度条件下混沌系统动力特征退化会产生短周期现象,介绍了几种加入扰动的混沌序列加密算法,并在此基础上得到一种复合的混沌加密算法,这种加密算法既用到了混沌系统参数扰动、又用到了混沌系统变量扰动,既具有级联混沌系统的优势又具有复合混沌系统的优势,能够得到复杂度高、分布均匀的混沌加密序列,并且便于实现.
This paper introduce several kinds of the chaotic perturbation motion array encryption algorithm, and get a new chaotic encryption algorithm on these encryption algorithm bases. This encryption algorithm has arrived at chaotic system variable and chaotic system perturbation motion. There are both systematic chaotic level couplet advantage and systematic chaotic compound advantage. It is easy to get complicated degree height, distribute enerypt an array, and get homogeneous chaotic nature realization.
