The 0-1 test for chaos, which is a simple binary method, has been widely used to detect the nonlinear behaviors of non-cascade chaotic dynamics. In this paper, validity checks chaos popular cascade Logistic-Cubic (L-C) system conducted through exploring effects sensitivity parameters. Results show that periodic, weak-chaotic, and strong-chaotic states L-C can be effectively identified by introd...

In this paper, an image encryption algorithm based on DNA random coding and random operation combined with chaotic map is proposed. In order to produce sequences with more chaotic characteristics, a new spatiotemporal chaotic system is proposed by employing the Tent-Sine system (TSS) in the coupled map lattice (CML). SHA-256 hash of the plain image is used to generate secret keys. The Lorenz Ma...

Chaos is embedded to the he Charged System Search (CSS) to solve practical optimization problems. To improve the ability of global search, different chaotic maps are introduced and three chaotic-CSS methods are developed. A comparison of these variants and the standard CSS demonstrates the superiority and suitability of the selected variants for practical civil optimization problems.

In this paper, we have presented a new permutation-substitution image encryption architecture using chaotic maps and Tompkins-Paige algorithm. The proposed encryption system includes two major parts, chaotic pixels permutation and chaotic pixels substitution. A logistic map is used to generate a bit sequence, which is used to generate pseudorandom numbers in TompkinsPaige algorithm, in 2D permu...

A digital watermark is a visible, or preferably invisible, identification code that is permanently embedded in digital media, to prove owner authentication and provide protection for documents. Given the interest in watermark generation using chaotic functions a detailed study of one chaotic function for this purpose is performed. In this paper, we present an approach for the generation of wate...

The combination of chaotic theory and cryptography forms an important field of information security. In the past decade, chaos based image encryption is given much attention in the research of information security and a lot of image encryption algorithms based on chaotic maps have been proposed. Due to some inherent features of images like bulk data capacity and high data redundancy, the encryp...

The security of chaos communication system is superior to other digital communication system, because it has characteristics such as non-periodic, wide-band, nonpredictability, easy implementation and sensitive initial condition. Chaos sequences are non – periodic sequences which are sensitive to their initial conditions i.e. spread factor and time delay respectively. If many antennas are appli...

This paper introduces a simple and effective improved one-dimension (1D) Logistic chaotic map. Simulations and performance evaluations show that the improved 1D Logistic chaotic map is able to get larger chaotic range and better chaotic behaviors compared with its prototype map. To investigate its applications in multimedia security, I propose an efficient encryption algorithm for color image. ...

Abstract: This paper presents an application of Iterative Learning Control (ILC) theory to secure communication system design by using chaotic signals, where the logistic-map is employed as a source of chaos. Meanwhile, the ILC scheme is employed as a tool to encrypt and decrypt a message. A set of numerical experiments is realized to evidence the performance of our system, including the noisy ...
