In this paper, we propose an adaptive encryption scheme for color images using Multiple Distinct Chaotic Maps (MDCM) and DNA computing. We have chosen three distinct chaotic maps, including a 2D-Henon map, Tent Logistic to separately encrypt the red, green, blue channels of original image. The proposed adaptively modifies parameters utilizing various statistical characteristics such as mean, va...

In this study, we investigate switching synchronization phenomena which are observed in coupled chaotic maps. Two logistic maps with generating intermittency chaos near three periodic window are coupled as a CML coupling topology. Moreover, we compare obtained synchronization states of coupled maps with coupled chaotic circuits.

We introduce and study the classical and quantum mechanics of certain non hyperbolic maps on the unit square. These maps are modifications of the usual baker's map and their behaviour ranges from chaotic motion on the whole measure to chaos on a set of measure zero. Thus we have called these maps " lazy baker maps. " The aim of introducing these maps is to provide the simplest models of systems...

In this work, we present multiple variations of the Multi-verse Optimizer Algorithm (MVO) using chaotic maps, it in formation new solutions. these MVO algorithm, which call Fuzzy-Chaotic (FCMVO), use maps used literature to substitute some parameters for original algorithm a random value universes or To implement chaos theory on variants, also Fuzzy Logic dynamic parameter adaptation; first tes...

In this paper we introduce two innovative image and video watermarking algorithms. The paper’s main emphasis is on the use of chaotic maps to boost the algorithms’ security and resistance against attacks. By encrypting the watermark information in a one dimensional chaotic map, we make the extraction of watermark for potential attackers very hard. In another approach, we select embedding po...

Secure multimedia communication presents new challenges that are difficult to handle by using the currently adopted encryption methods. Chaotic encryption is a new direction of cryptography. It uses chaotic system properties such as sensitivity to initial condition and loss of information. In order to reach higher performance, these methods take advantage of the more and more complex behavior o...

Haar wavelet is one of the best mathematical tools in image cryptography and analysis. Because of the specific structure, this wavelet has the ability which is combined with other mathematical tools such as chaotic maps. The rational order chaotic maps are one of clusters of chaotic maps which their deterministic behaviors have high sensitivity. In this paper, we propose a novel method of gradi...

This paper proposes a theorem to generate chaotic key stream from topologically conjugated maps of Tent Map. In this theorem, the condition for topological conjugation between Tent Map and a class of chaotic maps is first determined. Then, the chaotic attractor of the maps is divided into 2 unequal subintervals, the chaotic orbit is sampled once in n time iteration, and, finally, the independen...
