提出了一种基于双随机相位编码的傅里叶域彩色图像数字相位加密技术。在加密之前，将RGB输入图像带到HSV颜色空间，然后转换为相位。在解密过程中，HSV图像被转换回RGB格式。在加密期间使用的随机相位码通过堆叠三个二维随机相位掩模来准备。这些随机相位码用作加密和解密的密钥。该技术具有相位加密的所有优点，并且本质上是三维的。该技术的鲁棒性进行了分析，对随机相位码的变化和洗牌的随机相位掩模的一个给定的相位码。针对傅里叶平面随机相位码以及加密图像的遮挡，验证了该方案的性能。噪声攻击和使用正确的随机相位码的部分窗口的攻击的效果也进行了检查。数字仿真来支持这个想法。
A double random phase encoding based digital phase encryption technique for colored images is proposed in the Fourier domain. The RGB input image is brought to HSV color space and then converted into phase, prior to the encryption. In the decryption process the HSV image is and converted back to the RGB format. The random phase codes used during encryption are prepared by stacking three two-dimensional random phase masks. These random phase codes serve as keys for encryption and decryption. The proposed technique carries all the advantages of phase encryption and is supposedly three-dimensional in nature. Robustness of the technique is analyzed against the variations in random phase codes and shuffling of the random phase masks of a given phase code. Performance of the scheme is also verified against occlusion of Fourier plane random phase code as well as the encrypted image. Effects of noise attacks and attacks using partial windows of correct random phase codes have also been checked. Digital simulations are presented to support the idea.
