Security and Privacy in Sensor-Actuator Networks
The deployment of wireless sensor-actuator networks for physical sensing and control introduces a number of unique challenges, namely due to the cyber-physical implications of sensing and actuation. Moreover, the small form factor, reliance on battery energy, deployment of unattended devices in potentially challenging or harmful environments, and criticality of timely delivery of control signals further complicate any approach to secure the sensing and actuation processes. Recently, sensor-actuator networks have found new applications in vehicular systems, smart environments, and immersive media applications. Each of these domains presents new requirements and challenges to security and privacy, and we are actively investigating many of them.
