Double Image Encryption Algorithm Based on Random Fractional Fourier Transform
基于随机分数傅里叶变换的双图像加密算法

Double image encryption algorithm is proposed based on optical random fractional Fourier transform.Optical implementation of the scheme is presented.In this algorithm,two images were regarded as the amplitude and phase distributions of input complex function in encryption system.The complex function is encrypted by use of random fractional Fourier transform.The phase information is from the output phase of the transform.The random phase in random fractional Fourier transform is considered as the key of the ...
