A large number of analog chaos-based secure communication systems have been
proposed since the early 1990s exploiting the technique of chaos synchronization. A brief …

In recent years, a large amount of work on chaos-based cryptosystems have been
published. However, many of the proposed schemes fail to explain or do not possess a …

This paper describes the security weakness of a recently proposed secure communication
method based on discrete-time chaos synchronization. We show that the security is …

Over the past decade, there has been tremendous interest in studying the behavior of
chaotic systems. They are characterized by sensitive dependence on initial conditions …

Chaos theory is well known as one of three revolutions in physical sciences in 20th-century,
as one physicist called it: Relativity eliminated the Newtonian illusion of absolute space and …

In recent years, a great amount of secure communications systems based on chaotic
synchronization have been published. Most of the proposed schemes fail to explain a …

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 …

During the last decade a new approach for secure communication, based on chaotic
dynamics attracted the attention of the scientific community. In this chapter we give an …

A new approach to chaos communication is proposed to encrypt digital information using
controlled projective synchronisation. The scheme encrypts a binary sequence by …

This issue is a collection of contributions on recent developments and achievements of
cryptography and communications using chaos. The various contributions report important …
