Sécurité dans les réseaux de capteurs sans fils

The emergence of wireless sensor networks (WSNs) open the way with a multitude of fields of research constituting the privileged seats of their deployment. WSNs consist of small nodes with sensing computation and wireless communication capabilities and expected to play an essential role in the upcoming age of pervasive computing. Due to their constraints in computation memory power resources and its deployment in unattended and hostile environments individual sensors are vulnerable to security compromise and susceptible to physical capture. Furthermore using wireless communications makes security a challenge in these networks. As a result security must be an important factor to have in mind when designing WSNs. In this book we present a study of wireless sensor networks security problem in these networks we present also a state-of-the-art of key management protocols as consequence we propose a new protocol for key management.
