Feedback synchronization of the fractional order reverse butterfly-shaped chaotic system and its application to digital cryptography

Abstract

In this paper, the stability conditions and chaotic behaviors of new different fractional orders of reverse butterfly-shaped dynamical system are analytically and numerically investigated. Designing an appropriate feedback controller, the fractional order chaotic system is synchronized. Applying the synchronized fractional order systems in digital cryptography, a well secured key system is obtained. The numerical simulations are given to validate the correctness of the proposed synchronized fractional order chaotic systems and proposed key system. © 2013 Springer Science+Business Media Dordrecht.
