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

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.
In this note, a novel symmetric (also known as private-key or secret-key) cryptosystem is designed based on chaotic oscillators such as Du$ng's or a generalized Van der Pol's oscillator. Cryptography is one of the oldest human practices for communicating secretly with intended parties; see, e.g., r
