在本文中，我们提出了一种基于阿诺德变换（ART）和干涉法对彩色图像进行加密的新方法。一幅彩色图像被分解为三个独立的通道，即红色、绿色和蓝色，然后每个通道基于阿诺德变换和干涉法被加密为两个随机相位掩模。在图像解密过程中，使用具有相应波长的光源照射恢复的纯相位掩模。还分析了安全参数对解密图像的影响。给出了数值模拟结果以说明所提方法的可行性和有效性。（c）2009爱思唯尔有限公司。保留所有权利。
In this paper, we propose a novel method to encrypt a color image based on Arnold transform (ART) and interference method. A color image is decomposed into three independent channels, i.e., red, green and blue, and each channel is then encrypted into two random phase masks based on the ART and interference method. Light sources with corresponding wavelengths are used to illuminate the retrieved phase-only masks during image decryption. The influence of security parameters on decrypted images is also analyzed. Numerical simulation results are presented to illustrate the feasibility and effectiveness of the proposed method. (c) 2009 Elsevier B.V. All rights reserved.
