PINsight: Systematic Threat Assessment of Cross-Domain Wi-Fi-based PIN Inference
Johannes Kortz, Christof Paar, Christian Zenger +1
Wi-Fi signals can be repurposed as radar-like sensors, exposing a side channel for inferring sensitive information. A particularly concerning example is PIN inference, where an att…
Anti-Tamper Radio meets Reconfigurable Intelligent Surface for System-Level Tamper Detection
Maryam Shaygan Tabar, Johannes Kortz, Paul Staat +3
Many computing systems need to be protected against physical attacks using active tamper detection based on sensors. One technical solution is to employ an ATR (Anti-Tamper Radio)…
RIS-Jamming: Breaking Key Consistency in Channel Reciprocity-based Key Generation
Guyue Li, Paul Staat, Haoyu Li +6
Channel Reciprocity-based Key Generation (CRKG) exploits reciprocal channel randomness to establish shared secret keys between wireless terminals. This new security technique is ex…
Analog Physical-Layer Relay Attacks with Application to Bluetooth and Phase-Based Ranging
Paul Staat, Kai Jansen, Christian Zenger +2
Today, we use smartphones as multi-purpose devices that communicate with their environment to implement context-aware services, including asset tracking, indoor localization, conta…
Anti-Tamper Radio: System-Level Tamper Detection for Computing Systems
Paul Staat, Johannes Tobisch, Christian Zenger +1
A whole range of attacks becomes possible when adversaries gain physical access to computing systems that process or contain sensitive data. Examples include side-channel analysis,…
Reconfigurable Intelligent Surface for Physical Layer Key Generation: Constructive or Destructive?
Guyue Li, Lei Hu, Paul Staat +4
Physical layer key generation (PKG) is a promising means to provide on-the-fly shared secret keys by exploiting the intrinsic randomness of the radio channel. However, the performa…
Mirror Mirror on the Wall: Wireless Environment Reconfiguration Attacks Based on Fast Software-Controlled Surfaces
Paul Staat, Harald Elders-Boll, Markus Heinrichs +2
The intelligent reflecting surface (IRS) is a promising new paradigm in wireless communications for meeting the growing connectivity demands in next-generation mobile networks. IRS…
Kalman filter based MIMO CSI phase recovery for COTS WiFi devices
Chu Li, Jeremy Brauer, Aydin Sezgin +1
Recently channel state information (CSI) measurements from commercial multi input multi output (MIMO) WiFi systems have been ubiquitously used for different wireless sensing applic…
Keys from the Sky: A First Exploration of Physical-Layer Security Using Satellite Links
Pascal Zimmer, Roland Weinreich, Christian T. Zenger +2
In this paper, we investigate physical-layer security (PLS) methods for proximity-based group-key establishment and proof of location. Fields of application include secure car-to-c…
Intelligent Reflecting Surface-Assisted Wireless Key Generation for Low-Entropy Environments
Paul Staat, Harald Elders-Boll, Markus Heinrichs +3
Physical layer key generation is a promising candidate for cryptographic key establishment between two wireless communication parties. It offers information-theoretic security and…
The Passive Eavesdropper Affects my Channel: Secret-Key Rates under Real-World Conditions (Extended Version)
Christan Zenger, Hendrik Vogt, Jan Zimmer +2
Channel-reciprocity based key generation (CRKG) has gained significant importance as it has recently been proposed as a potential lightweight security solution for IoT devices. How…
