The unprecedented growth in production and exchange of multimedia over unsecured channels is overwhelming mathematicians, scientists engineers to realize secure efficient cryptographic algorithms. In this paper, a color image encryption algorithm combining the KAA map with multiple chaotic maps proposed. proposed makes full use Shannon’s ideas security, such that carried out through bit confusi...

Robust chaos occurs when a dynamical system has a neighborhood in parameter space such that there is one unique chaotic attractor, and no periodic attractors are present [Barreto et al., 1997; Banerjee et al., 19981. This behavior, expected to be relevant for any practical applications of chaos, was shown to exist in a general family of piecewise-smooth twodimensional maps, but conjectured to b...

Digital Watermarking is an ever increasing and important discipline, especially in the modern electronically-driven world. Watermarking aims to embed a piece of information into digital documents which their owner can use to prove that the document is theirs, at a later stage. In this paper, performance analysis of watermarking schemes is performed on white noise sequences and chaotic sequences...

Low cost RFID tags pose unique security and privacy challenges. There is an unresolved issue however of data tampering. Here we propose a watermarking based tamper detection solution for low cost RFID tags where the Object Class (OC) and the Serial number (SN) field of an RFID tag are used as the cover medium. Additionally, the use of a chaotic map (i.e. Skew Tent Map) in the watermark embeddin...

The Phasmatodea Population Evolution (PPE) algorithm, inspired by the evolution of phasmatodea population, is a recently proposed meta-heuristic algorithm that has been applied to solve problems in engineering. Chaos theory increasingly enhance performance and convergence algorithms. In this paper, we introduce chaotic mapping into PPE propose new Chaotic-based (CPPE) algorithm. map replaces in...

Particle swarm optimization (PSO) is a population-based stochastic optimization that has been widely applied to a variety of problems. However, it is easily trapped into the local optima and appears premature convergence during the search process. To address these problems, we propose a new particle swarm optimization by introducing chaotic maps (tent map and logistic map) and Gaussian mutation...

Using the Perron-Frobenius operator we establish a new functional central limit theorem result for non-invertible measure preserving maps that are not necessarily ergodic. We apply the result to asymptotically periodic transformations and give an extensive specific example using the tent map.

In the last ten years the interest for chaos has increased due to the great resources represented by the dynamical chaotic systems which can be used to assure secure and wide band communications. Also, chaotic systems are widely used to design analog and digital blocks for communication systems. In this paper we present some aspects regarding the hardware implementation of one well-known digita...

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...
