| 摘 要： | 混沌系统具有对初始条件的极端敏感性,初始条件的微小差异,将导致混沌系统的轨道演化很快变得互不相关,混沌的这种特性能很好地满足密码学的要求.提出了一种新的混沌加密算法模型,它以传统的分组加密思想为基础,把离散的Logistic映射与基于空间混沌的cat映射相结合,实现了对多媒体视频流AVI文件加密,实验表明该算法具有加密复杂度高和抗破译能力强等特点.

| Abstract: | Chaotic system is sensitive to initial conditions.Slight difference in initial conditions leads to totally different trajectory.This feature makes chaotic system fit for encryption.A new chaotic encryption algorithm is advanced.Based on traditional idea of block encryption,the algorithm combines the Logistic map with cat map,and the implementation of muti-media AVI files encryption is realized.Experiment indicates that this algorithm has the characteristics of high complexity and strong attack resistance. |
