On the security defects of an image encryption scheme
Chengqing Li, Shujun Li, Muhammad Asim +3
This paper studies the security of a recently-proposed chaos-based image encryption scheme, and points out the following problems: 1) there exist a number of invalid keys and weak…
Trident, a new pseudo random number generator based on coupled chaotic maps
A. B. Orue, G. Alvarez, A. Guerra +3
This article describes a new family of cryptographically secure pseudorandom number generators, based on coupled chaotic maps, that will serve as keystream in a stream cipher. The…
Cryptanalysis of a family of self-synchronizing chaotic stream ciphers
David Arroyo, Gonzalo Alvarez, Jose Maria Amigo +1
Unimodal maps have been broadly used as a base of new encryption strategies. Recently, a stream cipher has been proposed in the literature, whose keystream is basically a symbolic…
Some hints for the design of digital chaos-based cryptosystems: lessons learned from cryptanalysis
David Arroyo, Gonzalo Alvarez, Shujun Li
In this work we comment some conclusions derived from the analysis of recent proposals on the field of chaos-based cryptography. These observations remark the main problems detecte…
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…
