JAMMING-RESILIENT CONTROL AND COMMUNICATION FRAMEWORK FOR CYBER PHYSICAL SYSTEMS. Tomic, I.
abstract   bibtex   
The control and monitoring of large infrastructure installations is becoming smarter, cheaper to run and easier to manage through the use of wireless sensor and actuator networks (WSANs). Cyber Physical Systems (CPSs) are the combination of cyber sensing via WSANs and physical control. The problem with the use of WSANs in CPSs is that they make the whole system being controlled exposed to the world and vulnerable to theft or cyber-attacks. In this article we examine the failure of CPS infrastructure due to intelligent radio jamming. The intelligent jammer employs a protocol-aware jamming strategy to learn the transmission period of a sensor device. It then broadcasts noise to disrupt the wireless communication and destabilise the CPS. We present a CPS control and communication approach to counter the threat of intelligent radio jamming. The approach exploits the properties of the event-based control strategy combined with a reservation-based communication protocol that employs obfuscation. We use a physical model of a water distribution network to demonstrate that the approach is resilient to an intelligent jamming attack, it is able to continue normal operation of the system and maintain the desired level of performance while achieving low overheads.
