Introduction The idea of using chaotic transformations in cryptography is explicit in the
foundational papers of Shannon on secrecy systems (eg,[96]). Although the word “chaos” …

Introduction Cryptanalysis is an integral part of any serious effort in designing secure
encryption algorithms. Indeed, a cryptosystem is only as secure as the most powerful known …

In the last decade, chaos has emerged as a new promising candidate for cryptography
because many chaos fundamental characteristics such as a broadband spectrum …

Chaos-based cryptography, since its inception, has become a widely published subject.
Despite the vast amount of contributions in the area, its applications in real-world scenarios …

In this work we comment some conclusions derived from the analysis of recent proposals in
the field of chaos-based cryptography. These observations remark a number of major …

In recent years, a growing number of cryptosystems based on chaos have been proposed,
many of them fundamentally flawed by a lack of robustness and security. In this Letter, we …

Since 1980s, the idea of using digital chaotic systems to design new ciphers has attracted
more and more attention. The use of chaos in cryptography depends on the natural relation …

In this paper, methods are shown how to adapt invertible two-dimensional chaotic maps on
a torus or on a square to create new symmetric block encryption schemes. A chaotic map is …

Introduction The story of chaos-based or “chaotic” cryptography is remarkable, for several
reasons. To begin with, it appeared outside conventional cryptography, first as an …

This paper is devoted to the analysis of the impact of chaos-based techniques on block
encryption ciphers. We present several chaos based ciphers. Using the well-known …
