Abstract : The security in Industrial Control Systems is a major concern. Indeed, these systems manage installations that play an important economical role. Furthermore, targeting these systems can lead not only to economical losses but can also threaten human lives. Therefore, and as these systems depend on sensing data, it becomes obvious that additionally to real-time requirement, it is important to secure communication channels between these sensors and the main controllers. These issues are more challenging inWireless Sensor Networks (WSN) as the use of wireless communications brings its own security weaknesses. This thesis aims to address WSN-based security issues. Firstly, we conduct an in-deep security study of the WirelessHART protocol. This latter is the leading protocol for Wireless Industrial Sensor Networks (WISN) and is the first international approved standard. We assess its strengths and emphasize its weaknesses and limitations. In particular, we describe two harmful security vulnerabilities in the communication scheme of WirelessHART and propose improvement in order to mitigate them. Secondly, we present wIDS, a multilayer specification based Intrusion Detection System (IDS) specially tailored for Wireless Industrial Sensor Networks. The proposed IDS checks the compliance of each action performed by a wireless node based on a formal model of the expected normal behavior.
