A Basic Framework for the Cryptanalysis of Digital Chaos-Based Cryptography
David Arroyo, Gonzalo Alvarez, Veronica Fernandez
Chaotic cryptography is based on the properties of chaos as source of entropy. Many different schemes have been proposed to take advantage of those properties and to design new str…
Cryptanalysis of a new chaotic cryptosystem based on ergodicity
David Arroyo, Gonzalo Alvarez, Shujun Li +2
This paper analyzes the security of a recent cryptosystem based on the ergodicity property of chaotic maps. It is shown how to obtain the secret key using a chosen-ciphertext attac…
On the inadequacy of the logistic map for cryptographic applications
David Arroyo, Gonzalo Alvarez, Veronica Fernandez
This paper analyzes the use of the logistic map for cryptographic applications. The most important characteristics of the logistic map are shown in order to prove the inconvenience…
On the security of a new image encryption scheme based on chaotic map lattices
David Arroyo, Rhouma Rhouma, Gonzalo Alvarez +2
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…
Lorenz System Parameter Determination and Application to Break the Security of Two-channel Chaotic Cryptosystems
A. B. Orue, G. Alvarez, M. Romera +3
This paper describes how to determine the parameter values of the chaotic Lorenz system used in a two-channel cryptosystem. The geometrical properties of the Lorenz system are used…
