Physical processes that are sensed and actuated play an important role in the general Internet of Things (IoT), and in particular in Industrial Control Systems (ICS). From a security perspective, the physical layer allows for novel interactions of the (local) attacker with the system, and manipulating the physical process itself could be the target of the attacker. In addition, physical processes could also be leveraged for attack detection, and laws of physics constrain even strong attackers. As result, research in that area needs to be interdisciplinary and connect traditional engineering domains such as wireless communications, systems engineering, and information security. In this talk, a number of physical-layer security aspects relating to wireless communications, IoT, and ICS are discussed. In particular, focus will be on attacks and detection mechanisms for ICS, and time-of-arrival-based localization used in GPS and distance bounding.
He is an Assistant Professor at the Information Systems Technology and Design Pillar, at the Singapore University of Technology and Design (SUTD). He earned his Dr. Sc. in Computer Science from ETH Zurich (Switzerland) in 2012. At ETH, he was part of the System Security group led by Prof. Srdjan Capkun. Before coming to ETH, he received a degree in Computer Engineering (Dipl. Ing.) from the Hamburg University of Technology (Germany) in 2007. His Masters’ thesis on side-channel attack-resistant embedded crypto was supervised by Prof. Dieter Gollmann (TUHH), and Dr. Heike Neumann (NXP). The thesis won the K-H Ditze award for TUHH’s best Masters’ thesis in 2007. He was also awarded a DAAD scholarship to study for one year at the University of Waterloo, Ontario, Canada between 2004-2005.
