Author: Alvarez, Gonzalo; Li, Shujun
Year of publication: 2009
Published in: Communications in Nonlinear Science and Numerical Simulation ; 14 (2009), 11. - pp. 3743-3749

Summary:
This paper describes the security weakness of a recently proposed image encryption algorithm based on a logistic-like new chaotic map. We show that the chaotic map s distribution is far from ideal, thus making it a bad candidate as a pseudo-random stream generator. As a consequence, the images encrypted with this algorithm are shown to be breakable through different attacks of variable complexity.
