In this paper, the Hybrid-II method for encrypting multiple images by combining simple modified diffractive imaging-based encoding (SMDIBE) and compressive sensing (CS) algorithm is developed. Separately encrypted images are combined in a single plane with the space multiplexing technique and authorization is provided for different users. The matrix size of the ciphertext is also reduced by a method that reproduces the plane containing images as amplitude and phase information. With the Hybrid-II method, a different solution has been introduced to the limited space and noiseless images transmission issues where the multiple-image encryption methods are experiencing problems. Reliability is enhanced by combining SMDIBE and CS techniques with a strong non-linear structure. After the space multiplexing, the pixel scrambling and the CS technique have provided additional key space in the method. A maximum of 121 images can be encrypted without noise for individual users with a single...

基于压缩感知和衍射成像的多图像混合加密

本文提出了一种混合II方法，该方法将简单的基于改进的基于衍射成像的编码（SMDIBE）和基于压缩感知（CS）的算法相结合来加密多张图像。使用空间复用技术将单独加密的图像组合在一个平面中，并为不同的用户提供授权。通过将包含图像的平面作为幅度和相位信息进行再现的方法，也可以减小密文的矩阵大小。使用Hybrid-II方法，已针对空间受限和无噪声图像传输问题（其中多图像加密方法遇到问题）引入了不同的解决方案。通过将SMDIBE和CS技术与强大的非线性结构相结合，可以提高可靠性。空间多路复用后 像素加扰和CS技术为该方法提供了额外的键空间。单个用户最多可以加密121张图像而不会产生噪音。
