In this work, we propose a novel color image encryption scheme based on symmetric keys
using the synergistic approach of Arnold transform, 3D logistic chaotic map with XOR …

A new color image encryption algorithm is presented in this work by invoking a coupled
configuration of the two-dimensional Hénon map, the three-dimensional logistic map with …

This paper presents a novel secure medical image transmission scheme using hybrid visual
cryptography and Hill cipher (HVCHC) between sender and receiver. The gray scale …

Abstract Customarily, 8× 8 S-box is a 16× 16 look up table over Galois field GF 2 8, algebra
over the binary field F 2. A 12× 12 S-box over GF 2 12 is not workable as the computer …

This paper designs a novel multiple image encryption technique utilizing affine Hill cipher
(AHC), reality-preserving two-dimensional discrete fractional Hartley transform (RP2DFrHT) …

The security system for RGB image information is very critical issue in current time. In this
security system, we have proposed an algorithm for encryption and decryption of RGB …

This paper presents a generalization of chaotic systems using two-dimensional affine
transformations with six introduced parameters to achieve scaling, reflection, rotation …

Cybercrime is one of the most serious threats. Efforts are made to reduce the number of
cybercrime is to find new techniques in securing data such as Cryptography, Steganography …

In the current era of digital communication, the security of data transmitted relies heavily on
cryptographic algorithms. Transmission of digital images through an insecure channel is …

The major problems of Visual Secret Sharing (VSS) are the pixel expansion and lossy
recovery. The former creates large-sized shared images and makes their handling, storage …
