Tutorial
on Control
theory in Chaos-based Private Communications
|
Delivered by: Prof. Gilles
Millérioux
Centre de Recherche en Automatique de Nancy,
Nancy University,
France
Dynamical systems play a central role in the design of
symmetric cryptosystems. Their use has been widely investigated in
``chaos-based'' private communications. In this workshop, we review and
compare different design approaches which have been proposed in the open
literature and fully-specified algorithms are detailed for illustration
purpose. Issues regarding the efficiency of these algorithms in terms of
synchronization abilities and security are discussed. We highlight the
reason why some concepts borrowed from control theory appear to be useful
to this end.

§ Tutorial on Observer design for
chaotic synchronisation
|
|
|
Delivered
by: Dr. Krishna Busawon
Northumbria Communication Research
Lab,
Northumbria University
UK
This tutorial is a follow up of the tutorial given by Professor
Gilles Millerioux. It will basically tackle the issue of observer design
for chaotic synchronisation purposes. First, a general overview of linear
observer design will be given. Next, the main problems involved in
nonlinear observer design will be discussed. The main definitions and
concepts such as distinguishability, observability, detectability etc. will
be presented. Finally, the use of observers for message recovery purpose in
chaotic communication schemes will be discussed. A specific case study will
be studied and online simulations (using Matlab/Simulink) will be carried
out.
