“…One of the best ways to develop a method that is robust to CPA is to make the use of the mathematical model meaningless by preventing the direct relationship between the plaintext and corresponding ciphertext. Studies have also been done to solve the vulnerability of diffractive imaging-based encryption against CPA in this way [31,79,83].…”

Secure communication is of great importance in the modern world. Many methods, techniques, and systems are used for secure communication, many of which cannot be used in applications due to various reasons. Optical methods have been developed for secure communication in the last 25 years. In this study, optical encryption methods are examined in three sections. In the first section, single image optical encryption techniques are analyzed, while in the second section, multiple-image optical encryption techniques are examined. In the last section, standard test techniques for security are examined. The main single image optical encryption techniques are double random phase encoding (DRPE), DRPE and photon counting, phase truncated Fourier transform-based asymmetric optical encryption, diffractive imaging-based optical encryption, interference-based image encryption, and ghost imaging-based optical encryption. The main techniques of multiple-image optical encryption are wavelength multiplexing-based multiple-image encryption, position multiplexing-based multiple-image encryption, phase retrieval-based multiple-image encryption, 4-f correlation-based image encryption, and compressive sensing-based multiple-image encryption. These methods have been analyzed in detail and their advantages, disadvantages, and MATLAB application codes are given in the .

Image coding technology has become an indispensable technology in the field of modern information. With the vigorous development of the big data era, information security has received more attention. Image steganography is an important method of image encoding and hiding, and how to protect information security with this technology is worth studying. Using a basis of mathematical modeling, this paper makes innovations not only in improving the theoretical system of kernel function but also in constructing a random matrix to establish an information-hiding scheme. By using the random matrix as the reference matrix for secret-information steganography, due to the characteristics of the random matrix, the secret information set to be retrieved is very small, reducing the modification range of the steganography image and improving the steganography image quality and efficiency. This scheme can maintain the steganography image quality with a PSNR of 49.95 dB and steganography of 1.5 bits per pixel and can ensure that the steganography efficiency is improved by reducing the steganography set. In order to adapt to different steganography requirements and improve the steganography ability of the steganography schemes, this paper also proposes an adaptive large-capacity information-hiding scheme based on the random matrix. In this scheme, a method of expanding the random matrix is proposed, which can generate a corresponding random matrix according to different steganography capacity requirements to achieve the corresponding secret-information steganography. Two schemes are demonstrated through simulation experiments as well as an analysis of the steganography efficiency, steganography image quality, and steganography capacity and security. The experimental results show that the latter two schemes are better than the first two in terms of steganography capacity and steganography image quality.

“…However, vulnerability of the DIBE against to chosen plaintext attack (CPA) has been demonstrated despite of the advantages of DIBE by the study in 2015 [13]. Recently, a HYBRID method has been developed that combines data hiding and diffractive encoding, which enhances the resistance of the DIBE to CPA [14].…”

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 carrier. Experimental studies have also shown that the Hybrid-II method is resistant to chosen-plaintext and known plain-text attacks.
