Recently, a new chaotic cryptosystem using external 128-bit key and multiple chaotic maps has been proposed. In this paper, a fundamental flaw of this cryptosystem is pointed out and a known plaintext attack is presented. Furthermore, a remedial modification is suggested, which avoids the flaw while
In recent years, external key was introduced to chaotic cryptography by Pareek et al. and find its application in several discrete chaotic cryptosystems. The first part of this paper is devoted to the analysis of their essential weaknesses as well as some redundancies that contribute little to the s
