摘要

针对目前图像加密方法多局限于对方形图像进行加密的特点，提出了一种同时适用于方形和矩形图像的加密算法。将基于图像分割的新映射用于图像位置置乱，将含有混沌映射的扩散函数用于图像灰度置乱，从而得到位置置乱和灰度置乱相结合的加密算法。实验仿真结果表明该算法能够很好的实现对任意大小图像的加密，且具有密钥空间大，密钥敏感性强以及能够抵御统计和已知明文攻击等优点。

Abstract

Nowadays image encryption methods are mostly confined to a square image encryption

it proposed a new encryption algorithm which can be applied to both square and rectangular image encryption. Apply the new map that based on image segmentation to the location scrambling

and carry out image gray scrambling by using spread function that contain chaos map

so as to get an image encryption algorithm which combine position and gray scrambling. The results of Simulation show that this algorithm can achieve good image encryption of any size

and has a large key space

key sensitivity and it also has many other advantages such as withstand statistical and known expressly attack.
