An Image Encryption Method Based on Elliptic Curve Elgamal Encryption and Chaotic Systems

open access: yesIEEE Access, 2019
Due to the potential security problem about key management and distribution for the symmetric image encryption schemes, a novel asymmetric image encryption method is proposed in this paper, which is based on the elliptic curve ElGamal (EC-ElGamal ...

Continuous Time Chaotic Systems for Whale Optimization Algorithm

open access: yesAdvances in Electrical and Computer Engineering, 2018
Discrete time chaotic systems are often used instead of random number arrays in order to improve the convergence properties of optimization algorithms and prevent them to get stuck on local solutions.

Chaotic and Arnold stripes in weakly chaotic Hamiltonian systems [PDF]

open access: yesChaos: An Interdisciplinary Journal of Nonlinear Science, 2012
The dynamics in weakly chaotic Hamiltonian systems strongly depends on initial conditions (ICs) and little can be affirmed about generic behaviors. Using two distinct Hamiltonian systems, namely one particle in an open rectangular billiard and four particles globally coupled on a discrete lattice, we show that in these models, the transition from ...

Chaos in synthetic microbial communities.

open access: yesPLoS Computational Biology, 2022
Predictability is a fundamental requirement in biological engineering. As we move to building coordinated multicellular systems, the potential for such systems to display chaotic behaviour becomes a concern.

Synchronization of Incommensurate Fractional-Order Chaotic Systems Based on Linear Feedback Control

open access: yesFractal and Fractional, 2022
The dynamics and synchronization of fractional-order (FO) chaotic systems have received much attention in recent years. However, the research are focused mostly on FO commensurate systems.

Synchronization of fractional chaotic systems based on a simple Lyapunov function

open access: yesAdvances in Difference Equations, 2017
In this paper the synchronization of fractional-order chaotic systems and a new property of fractional derivatives are studied. Then we propose a new fractional-order extension of Lyapunov direct method to control the fractional-order chaotic systems.
