Ghost Peak: Practical Distance Reduction Attacks Against HRP UWB Ranging
Patrick Leu, Giovanni Camurati, Alexander Heinrich +5
We present the first over-the-air attack on IEEE 802.15.4z High-Rate Pulse Repetition Frequency (HRP) Ultra-WideBand (UWB) distance measurement systems. Specifically, we demonstrat…
AdaptOver: Adaptive Overshadowing Attacks in Cellular Networks
Simon Erni, Martin Kotuliak, Patrick Leu +2
In cellular networks, attacks on the communication link between a mobile device and the core network significantly impact privacy and availability. Up until now, fake base stations…
LTrack: Stealthy Tracking of Mobile Phones in LTE
Martin Kotuliak, Simon Erni, Patrick Leu +2
We introduce LTrack, a new tracking attack on LTE that allows an attacker to stealthily extract user devices' locations and permanent identifiers (IMSI). To remain stealthy, the lo…
Decentralized Privacy-Preserving Proximity Tracing
Carmela Troncoso, Mathias Payer, Jean-Pierre Hubaux +31
This document describes and analyzes a system for secure and privacy-preserving proximity tracing at large scale. This system, referred to as DP3T, provides a technological foundat…
UWB-ED: Distance Enlargement Attack Detection in Ultra-Wideband
Mridula Singh, Patrick Leu, AbdelRahman Abdou +1
Mobile autonomous systems, robots, and cyber-physical systems rely on accurate positioning information. To conduct distance-measurement, two devices exchange signals and, knowing t…
Message Time of Arrival Codes: A Fundamental Primitive for Secure Distance Measurement
Patrick Leu, Mridula Singh, Marc Roeschlin +2
Secure distance measurement and therefore secure Time-of-Arrival (ToA) measurement is critical for applications such as contactless payments, passive-keyless entry and start system…
