A novel optical double-image encryption scheme based on Gaussian apertured reality-preserving fractional Mellin transform (GARPFrMT) is proposed. In terms of optical image encryption, GARPFrMT has several attractive advantages: (1) The GAPRFrMT can be used to scramble the value of two images simultaneously; (2) GARPFrMT is constructed in diffraction domain to ensure that the ciphertext is real; (3) Owing to the nonlinearity, this transform can ensure that the proposed encryption system can be kept from the potential insecurity; and (4) A Gaussian lens is applied to improve intensity distributions of the output light. Experimental results demonstrate that the proposed algorithm is feasible and robust by a lot of attack analysis, i.e. sensitivity attack analysis (>99.60%), differential attack analysis (NPCR >99.6072 and UACI >33.5681%), entropy values (almost 7.99928), statistical attack (correlation coefficient values are almost 0), noise attack, cropping attack and NIST analysis.

基于高斯孔径保真分数梅林变换的光学双像加密

提出了一种新的基于高斯孔径真实保留分数梅林变换(GARPFrMT)的光学双像加密方案。在光学图像加密方面,GARPFrMT 有几个吸引人的优点: (1) GAPRFrMT 可用于同时对两幅图像的值进行加扰;(2) GARPFrMT在绕射域构造,保证密文真实;(3) 由于非线性,这种变换可以确保所提出的加密系统可以避免潜在的不安全性;(4)应用高斯透镜来改善输出光的强度分布。实验结果表明,通过大量攻击分析,即敏感性攻击分析(>99.60%)、差异攻击分析(NPCR>99.6072和UACI>33.5681%),该算法是可行的和鲁棒的
