“…Therefore, digital chaotic ciphers like those in [3,4,5] and traditional cryptographic techniques such as DES, IDEA and RSA are no longer suitable for practical image encryption, especially for real-time communication scenarios. So far, many chaos-based image cryptosystems have been proposed [6,7,8,9,10].…”

This paper reports a detailed cryptanalysis of a recently proposed encryption scheme based on the logistic map. Some problems are emphasized concerning the key space definition and the implementation of the cryptosystem using floating-point operations. It is also shown how it is possible to reduce considerably the key space through a ciphertext-only attack. Moreover, a timing attack allows the estimation of part of the key due to the existent relationship between this part of the key and the encryption/decryption time. As a result, the main features of the cryptosystem do not satisfy the demands of secure communications. Some hints are offered to improve the cryptosystem under study according to those requirements.Recently a new cryptosystem was proposed by using a chaotic map lattice (CML). In this paper, we analyze the security of this cryptosystem and point out some of its security defects. A number of measures have been suggested to enhance the security of the cryptosystem following some established guidelines on how to design good cryptosystems with chaos.

“…The growing of research interest in chaos and cryptography has resulted in a number of digital chaotic cryptographic approaches that realize private key cryptography with chaos [1,5,12]. Among those chaotic cryptographic schemes, the one proposed by Baptista [5] has attracted much interest.…”

We have proposed a chaotic cryptographic scheme based on iterating the logistic map and updating the look-up table dynamically. However, it has been broken recently. In this paper, the weaknesses of the original dynamic look-up table scheme are analyzed and a more secure chaotic encryption scheme based on this dynamic look-up table concept is proposed. Theoretical analysis indicates that the modified scheme can resist the reported attacks. Moreover, simulation results show that this encryption scheme leads to a flat ciphertext distribution.
