Cryptanalysis of a multi-chaotic systems based image cryptosystem

Optics Communications, Volume 283, No. 2, Year 2010

This paper is a cryptanalysis of a recently proposed multi-chaotic systems based image cryptosystem. The cryptosystem is composed of two shuffling stages parameterized by chaotically generated sequences. We propose and implement two different attacks which completely break this encryption scheme. © 2009 Elsevier B.V. All rights reserved.
