Sécurisation par dynamiques chaotiques des réseaux locaux sans fil au niveau de la couche MAC

Abstract : The security of wireless sensor network is a growing field of research hampered by limited battery life time and computing constraints. The originality of this thesis is to provide Low Power chaotic cryptosystems for sensor networks more suitable than conventional algorithms and achieve an implementation on a real platform.. We present first a state of the art of wireless networks, threats and constraints of the security process as well as conventional cryptographic techniques. We give an overview of the chaos theory and we validate the randomness of several chaotic maps by the NIST statistical tests. Then, we propose new methods of chaotic S-Box construction, while demonstrating their robustness against traditional attacks. Finally, we propose a new image encryption algorithm dedicated to wireless sensor network. Validation of our contributions is performed by simulation and experimental measurements on a platform of real sensor networks (SensLab).
