摘要

本文提出了一种基于Henon混沌映射的基于分数阶傅立叶变换FRFT的图像加密方案,该方案是为了满足高安全性图像的需要而引入的。该算法结合了FRFT的混淆和扩散的主要优点,使用Arnold Cat图进行混淆,Henon混沌图或其中一种提出的Henon混沌图进行扩散。将该算法与基于Arnold Cat map、Baker混沌map、Henon混沌map和RC6的图像加密算法进行了比较。在统计分析、处理时间和安全性分析等方面进行了比较。通过这些对比测试,作者发现本文算法的效果很好,甚至在某些情况下优于RC6和其他混沌映射。

Image Encryption Based on Development of Hénon Chaotic Maps using Fractional Fourier Transform
In this paper, the authors propose an image encryption scheme based on the development of a Henon chaotic map using fractional Fourier transform FRFT which is introduced to satisfy the necessity of high secure image. This proposed algorithm combines the main advantages of confusion and diffusion with FRFT, it use Arnold Cat map for confusion and Henon chaotic map or one of the proposed Henon chaotic maps for diffusion. The proposed algorithm is compared with some image encryption algorithms based on Arnold Cat map, Baker chaotic map, Henon chaotic map and RC6. The authors perform a comparison between them in several experimental tests as statistical analyses, processing time and security analysis. The authors find from these comparison tests that the proposed algorithm demonstrates good result even better than RC6 and other chaotic maps in some cases.
