本文提出了一种新的图像加密方案，该方案利用图像全置乱矩阵对图像像素的位置进行置乱，然后利用超混沌系统混淆明文图像和密文图像之间的关系。实验结果表明，该图像加密算法具有密钥空间大、安全性高的优点，加密后的y图像灰度值分布具有类随机性。(C)2007 Elsevier B.V.保留所有权利。
This Letter presents a new image encryption scheme, which employs an image total shuffling matrix to shuffle the positions of image pixels and then uses a hyper-chaotic system to confuse the relationship between the plain-image and the cipher-image. The experimental results demonstrate that the suggested encryption algorithm of image has the advantages of large key space and high security, and moreover, the distribution of grey values of the encrypted y image has a random-like behavior.
