In this paper we propose a new image randomness measure using Shannon entropy over
local image blocks. The proposed local Shannon entropy measure overcomes several …

In this paper, we propose and demonstrate experimentally a new wireless digital encryption
hyperchaotic communication system based on radio frequency (RF) communication …

A new hybrid chaotic map is constructed in this paper and applied to image encryption and
hiding. MD5 is used as part of initial condition and control parameter to perturb the trajectory …

Multimedia security has become extremely important with the extensive use of multimedia
data over the open-natured wireless channel. The total encryption performed by other …

Recently, a pixel-chaotic-shuffling (PCS) method has been proposed by Huang et al. for
encrypting color images using multiple chaotic systems like the Henon, the Lorenz, the …

Nowadays, many applications have been appeared due to the rapid development in the
term of telecommunication. One of these applications is the telemedicine where the patients' …

Chaotic map lattice (CML) has been used recently for digital image encryption; however, it
has several flaws in terms of irreversibility and violates some basic principles of …

This paper presents a triple image encryption based on integer transform and chaotic map.
Most of image encryption algorithm employ the confusion-diffusion architecture and operate …

This paper presents a digital image cryptosystem based on nonlinear dynamics of a
compound sine and cosine chaotic map. The compound sine and cosine chaotic map is …

The fast development in the term of telecommunication helps on the appearance of variety of
modern applications such as the telemedicine where the patients' digital data can transfer …
