In this paper we review a number of optical image encryption techniques proposed in the
literature inspired by the architecture of the classic optical Double Random Phase Encoding …

Over the years extensive studies have been carried out to apply coherent optics methods in
real-time communications and image transmission. This is especially true when a large …

In this paper, we proposed a novel and effective image encryption algorithm based on
Chaos and DNA encoding rules. Piecewise Linear Chaotic Map (PWLCM) and Logistic Map …

A color image encryption algorithm is designed by use of Arnold transform and discrete
cosine transform (DCT). The RGB components of the color image are scrambled by Arnold …

We demonstrate in this paper that the traditional double random phase encoding (DRPE)
technique is vulnerable to ciphertext-only attack (COA). In this method, an unauthorized user …

In this paper, an image encryption algorithm is proposed in which first the image pixels are
shuffled using the Arnold map. Second, a 256-bit key is generated using a 2D logistic Sine …

An image encryption is discussed based on the random phase encoding method in gyrator
domains. An iterative structure of image encryption is designed for introducing more random …

We demonstrate experimentally that the traditional double random phase encoding (DPRE)
technique is vulnerable to the cyphertext-only attack (COA). With the statistical ergodic …

In the modern era, the secure transmission and storage of information are among the utmost
priorities. Optical security protocols have demonstrated significant advantages over digital …

Conventional double-random phase encoding is vulnerable to a chosen or known plaintext
attack owing to the linearity of the system. We introduce a technique to break down this …
