基于分数阶小波变换（FWT），提出了一种新的图像加密方法。我们通过两个分数阶和一系列缩放因子对图像进行加密。该方法有两组密钥，只有当所有这些密钥都正确时，图像才能被解密。我们还可以利用这种方法实现部分加密。同时，提出了光学实现方式，并且一些数值模拟证明了其可行性。版权所有（c）2005爱思唯尔公司。保留所有权利。
Based on the fractional wavelet transform (FWT) a novel method for the image encryption is proposed. We encrypt the image by two fractional orders and a series of scaling factors. There are two series of keys in this method. Only when all of these keys are correct, the image could be decrypted. We can also realize the partial encryption by using this method. Meanwhile, the optical implementation is suggested and some numerical simulations prove its possibility. (c) 2005 Elsevier B.V. All rights reserved.
