About the speaker

Srdjan Capkun

ETH Zurich, Zurich, Switzerland
Srđan Čapkun is a Full Professor in the Department of Computer Science, ETH Zurich and Director of the Zurich Information Security and Privacy Center (ZISC). He was born in Split, Croatia. He received his Dipl.Ing. Degree in Electrical Engineering / Computer Science from the University of Split in 1998, and his Ph.D. degree in Communication Systems from EPFL in 2004. Prior to joining ETH Zurich in 2006 he was a postdoctoral researcher in the Networked & Embedded Systems Laboratory, University of California Los Angeles and an Assistant Professor in the Informatics and Mathematical Modelling Department, Technical University of Denmark. His research interests are in system and network security. One of his main focus areas is wireless security. In 2016 he received an ERC Consolidator Grant for a project on securing positioning in wireless networks.


In this talk I will review security issues in today's navigation and close-range positioning systems.
I will discuss why GNS systems like GPS are hard to fully secure and will present novel solutions
that can be used to improve the robustness of GNS systems to attacks. I will then show how a
different design of a positioning system can enable secure positioning, but also that this requires
solving a set of relevant physical- and logical- layer challenges. Finally I will present a design
and implementation of a fully integrated IR UWB secure distance measurement (distance bounding)
system that solves these challenges and enables secure distance measurement and secure positioning
in IoT applications.
