An image is a pertinent data because of its visual characteristics. Image should be encrypted appropriately due to sensitivity to changes as well as security perspective. But as of inherent characteristics of image, standard encryption algorithms are not appropriate for image encryption. Recently, research on image encryption using chaos theory has been emerged. In this research, work chaos bas...

Assuming ideal synchronization at the receivers, an approach to calculating the approximate theoretical bit-error rate (BER) of a coherent chaos-shift-keying (CSK) digital communication system under an additive white Gaussian noise environment is presented. The operation of a single-user coherent CSK system is reviewed and the BER is derived. Using a simple cubic map as the chaos generator, it ...

Chaos-based cryptography is widely investigated in recent years, especially in the field of random number generators. The paper describes a novel pseudo-random bit generator (PRBG) based on chaotic logistic maps. Three logistic maps are combined in the algorithmic process, and a block of 32 random bits is produced at each iteration. The binary64 double precision format is used according to the ...

The main aim of this paper is the utilization of discrete chaotic Lozi map based chaos number generator to enhance the performance of PSO algorithm. This paper presents the results of research, in whichchaos enhanced PSO algorithm is used to design an optimal PID controller for DC motor system. Obtained results are compared with other non-heuristic and heuristic methods.

Designing a pseudorandom number generator (PRNG) is a difficult and complex task. Many recent works have considered chaotic functions as the basis of built PRNGs: the quality of the output would indeed be an obvious consequence of some chaos properties. However, there is no direct reasoning that goes from chaotic functions to uniform distribution of the output. Moreover, embedding such kind of ...

G.Geetha Professor and Head, Division of Research and Development Lovely Professional University, Phagwara, India [email protected] Abstract We propose the fractal generation method to generate the different types of fractals using chaos theory. The fractals are generated by Iterated Function System (IFS) technique. The chaos theory is an unpredictable behavior arises in the dynamical system...

The paper presents a chaos-based True Random Number Generator (TRNG) implemented in commercially available mixed-signal PSoC reconfigurable devices without any external components. Contrary to the traditionally used sources of randomness (eg various ”well-behaved” analog noise sources) it uses well-defined deterministic analog circuit that exhibits chaos. A new simple method of mapping the dete...

The dissipative Lozi chaotic map is embedded in the Discrete Self OrganisingMigrating Algorithm (DSOMA) algorithm, as a pseudorandom number generator (PRNG). This novel chaotic based algorithm is applied to the flow shop with blocking scheduling problem. The algorithm is tested on the Taillard problem sets and compared favourably with published heuristics.

Utilization of chaotic signals for covert communications remains a very promising practical application. Multiple studies indicate that the major shortcoming of recently proposed chaos-based communication schemes is their susceptibility to noise and distortions in communication channels. In this paper, we review a new approach to communication with chaotic signals, which demonstrates good perfo...

On the other hand, since its definition by Chua&Yang [2], Cellular Neural Networks (CNNs) received a great deal of interest. Although many of these applications were proposed for numerous disciplines like artificial life and image processing [3], some have been adapted for chaos [4-7]. In one of these applications, Arena et al. realized unfolded Chua’s circuit using the connection of three simp...
