摘要

在当今时代，数字图像在传输过程中的安全是非常重要的。为此，密码技术和混沌映射都可以适用。在本文中，我们详细研究了使用Arnold 2D cat图、Baker图、Henon图、Cross混沌图和2D logistic图等不同的二维混沌图进行图像加密。利用NPCR (Number of Pixels Change Rate)和UACI (Unified Average Change Intensity)值对这些技术进行了安全性分析。NPCR和UACI的实验结果表明了不同技术加密过程的有效性。

Comparative study of image encryption using 2D chaotic map

Securing digital image during transmission is very much important in the current era. For this purpose, cryptographic techniques as well as chaotic maps can be applicable. In this paper, we have given a detailed study of the image encryption using different 2D chaotic maps such as Arnold 2D cat map, Baker map, Henon map, Cross chaos map and 2D logistic map. The security analysis of these techniques has been done by the help of NPCR (Number of Pixels Change Rate) and UACI (Unified Average Changing Intensity) values. The experimental results of NPCR and UACI show the effectiveness of the encryption processes of different techniques.
