Optical correlators are efficient optical systems that have gained a wide range of
applications both in image recognition and encryption, due to their special properties that …

We present, to our knowledge, a novel method to achieve experimental encryption using
double random phase encoding with full complex modulation and a single phase-only …

In this work, a novel symmetric cryptosystem for image encryption is presented. The
Symmetric Cryptosystem of the Elliptic Curve (SCEC) can resist damage to encrypted …

The Fresnel transform (FrT) is commonly used to describe the free-space propagation of
optical waves. In this work, we present new definitions for the convolution, correlation and …

The proposed algorithm called Image encryption based on chaos, elliptic curve, dynamic S-
boxes and variable permutations (IECC) is a symmetric cryptosystem for encrypting bmp …

In this paper, a novel scheme for the secure transmission of phase images is presented. A
phase image is bonded with a random amplitude mask and subjected to the Fresnel …
