  • Cryptanalysis of a multi-chaotic systems based image cryptosystem 

    Solak, Ercan; Rhouma, Rhouma; Belghith, Safya Mdimegh (ELSEVIER SCIENCE BV, 2010-01-15)
    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 ...
  • Cryptanalysis of a new substitution-diffusion based image cipher 

    Rhouma, Rhouma; Solak, Ercan; Belghith, Safya Mdimegh (ELSEVIER SCIENCE BV, 2010-07)
    This paper introduces two different types of attacks on a recently proposed cryptosystem based on chaotic standard and logistic maps. In the two attacks, only a pair of (plaintext/ciphertext) was needed to totally break ...
