Many encryption methods involving chaotic dynamics have been proposed in the literature
since the 1990's. Most of them consist of ldquomixingrdquo the confidential information …

The work presented in this paper deals with chaos synchronization of discrete-time switched
systems for communication purposes. In a chaotic masking scheme, the main problem …

In this paper, sufficient conditions of global synchronization in finite-time, which can be a
minimum, are presented for the generic class of piecewise linear maps. The conditions of …

In this paper, the problem of global chaos synchronization is addressed. Two propositions
borrowed from results of the robust control theory are established to achieve global …

This thesis deals with the synchronization of dynamical systems. The synchronization
considered is called master-slave, that is, the dynamical systems are connected in a …

Le travail développé dans ce manuscrit porte sur la synchronisation des systèmes
chaotiques. Il est articulé autour de deux axes principaux: la synthèse d'observateur et la …

An essential issue for the validation of ciphers is cryptanalysis, that is, the study of attacks in
order to reveal possible weaknesses. In this paper, we propose a systematic and unified …

In this chapter, it is shown how control-theoretical concepts can be useful in the design of
symmetric cryptosystems. The authors first provide some background on cryptography with …

Synchronization is a process through which a set of interconnected entities reach a similar
behaviour. This phenomenon is ubiquitous in nature, whether it concerns living things or not …

La thèse traite de l'utilisation des systèmes hybrides dans le contexte particulier des
communications sécurisées et de la cryptographie. Ce travail est motivé par les faits …
