Encryption algorithm based on improved four-dimensional chaotic system and dynamic DNA encoding

open access: yesAIP Advances
An image encryption algorithm is proposed based on the combination of genetic (DNA) random coding and chaotic mapping. An image encryption algorithm based on an improved new four-dimensional chaotic system and DNA coding is proposed to address the ...

Chaos synchronization of the new hyperchaotic Chen system via nonlinear control

open access: yesActa Physica Sinica, 2006
This paper studies chaos synchronization of the new hyperchaotic Chen system via nonlinear control. A new method for improving the Lyapunov function of error dynamics of synchronization designed by Jiang and Huang et al is presented. The method removes the limitation occasioned by the Lyapunov function having only one form.

Anti-Synchronization of Hyperchaotic Pang and Hyperchaotic Wang-Chen Systems Via Active Control

open access: yesInternational Journal of Control Theory and Computer Modeling, 2013
Hyperchaotic systems are chaotic systems having more than one positive Lyapunov exponent and they have important applications in secure data transmission and communication. This paper applies active control method for the synchronization of identical and different hyperchaotic Pang systems (2011) and hyperchaotic Wang-Chen systems (2008).
