Abstract

Chaos-based cryptography Cryptanalysis Image encryption Logistic map LOOK-UP TABLE EXTERNAL KEY SECURITY SCHEME CRYPTOGRAPHY SYSTEMS CIPHER CRYPTOSYSTEMS TRANSMISSION MAPS
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.
