Cryptanalysis of a Classical chaos-based cryptosystem with some quantum cryptography features
David Arroyo, Fernando Hernandez, Amalia B. Orúe
The application of synchronization theory to build up new cryptosystems has been a hot topic during the last two decades. In this paper we analyze a recent proposal in this field.…
Application of Gray codes to the study of the theory of symbolic dynamics of unimodal maps
David Arroyo, Gonzalo Alvarez
In this paper we provide a closed mathematical formulation of our previous results in the field of symbolic dynamics of unimodal maps. This being the case, we discuss the classical…
Breaking a Chaotic Cryptographic Scheme Based on Composition Maps
Chengqing Li, David Arroyo, Kwok-Tung Lo
Recently, a chaotic cryptographic scheme based on composition maps was proposed. This paper studies the security of the scheme and reports the following findings: 1) the scheme can…
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…
Estimation of the control parameter from symbolic sequences: Unimodal maps with variable critical point
David Arroyo, Gonzalo Alvarez, José María Amigó
The work described in this paper can be interpreted as an application of the order patterns of symbolic dynamics when dealing with unimodal maps. Specifically, it is shown how Gray…
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…
