PINSIGHT: A Comprehensive Threat Exploration of Domain-Adaptive Wi-Fi based PIN Code Inference
Johannes Kortz, Paul Staat, Christof Paar +1
Wi-Fi signals can be exploited by adversaries as a sensing side channel to eavesdrop on physical information. By monitoring propagation effects of radio waves within the victim's e…
Talking to the Airgap: Exploiting Radio-Less Embedded Devices as Radio Receivers
Paul Staat, Daniel Davidovich, Christof Paar
Physical isolation from external networks - an airgap - aims to minimize exposure to remote attacks. Yet capable adversaries still achieve code execution on air-gapped systems, and…
The Battle of Metasurfaces: Understanding Security in Smart Radio Environments
Paul Staat, Christof Paar, Swarun Kumar
Metasurfaces, or Reconfigurable Intelligent Surfaces (RISs), have emerged as a transformative technology for next-generation wireless systems, enabling digitally controlled manipul…
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)…
Key Exchange in the Quantum Era: Evaluating a Hybrid System of Public-Key Cryptography and Physical-Layer Security
Paul Staat, Meik Dörpinghaus, Azadeh Sheikholeslami +3
Today's information society relies on cryptography to achieve security goals such as confidentiality, integrity, authentication, and non-repudiation for digital communications. Her…
Spatial-Domain Wireless Jamming with Reconfigurable Intelligent Surfaces
Philipp Mackensen, Paul Staat, Stefan Roth +3
Wireless communication infrastructure is a cornerstone of modern digital society, yet it remains vulnerable to the persistent threat of wireless jamming. Attackers can easily creat…
