Abstract. Proximity, distance and location information is predominantly provided to devices through their radio interfaces. Many systems such as contactless payments, passive keyless entry and start systems, digital contact tracing, autonomous navigation, rely on the correctness of distance and location information. The ability of the attacker to manipulate distance or position information via relays and other physical-layer attacks can, in part or fully, violate the functioning of these systems and lead to theft of property and funds, physical damage or denial of service. A number of such attacks have been demonstrated in the last decade. In recent years, these physical-layer attacks have been integrated into attacker models and have an increasing impact on radio designs and standards, specifically UWB, WiFi and 5G. First distance measurement radios built specifically to resist physical-layer attacks have already been commercialized and are now deployed in the automotive industry. In this talk, Srdjan Capkun will provide an overview of this subject area, outlining the key challenges, proposed and deployed solutions, as well as ongoing research and standardization efforts. He will particularly focus on the security of the IEEE 802.15.4z standard and its LRP and HRP variants that are currently used in cars and smartphones.
Biography. Srdjan Capkun (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. 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 (NESL), University of California Los Angeles (UCLA) and an Assistant Professor in the Informatics and Mathematical Modelling Department, Technical University of Denmark (DTU). His research interests are in system and network security. His focus areas are wireless security (in particular secure positioning), and system security where he focuses on trusted computing and blockchain technologies. He is a co-founder of 3db Access, a company focusing on secure distance measurement and proximity-based access control, and of Sound-Proof a spin-off focusing on usable on-line authentication. In 2016 he received an ERC Consolidator Grant for a project on securing positioning in wireless networks. He is a fellow of the ACM.
