Maintaining App Services in Disrupted Cities: A Crisis and Resilience Evaluation Tool
Leon Würsching, Matthias Hollick
Disaster scenarios can disconnect entire cities from the core network (CN), isolating base stations (BSs) and disrupting the Internet connection of app services for many users. Suc…
BeamSec: A Practical mmWave Physical Layer Security Scheme Against Strong Adversaries
Afifa Ishtiaq, Arash Asadi, Ladan Khaloopour +3
The high directionality of millimeter-wave (mmWave) communication systems has proven effective in reducing the attack surface against eavesdropping, thus improving the physical lay…
Smartphones with UWB: Evaluating the Accuracy and Reliability of UWB Ranging
Alexander Heinrich, Sören Krollmann, Florentin Putz +1
More and more consumer devices implement the IEEE Ultra-Wide Band (UWB) standard to perform distance measurements for sensitive tasks such as keyless entry and startup of modern ca…
FIDO2 the Rescue? Platform vs. Roaming Authentication on Smartphones
Leon Würsching, Florentin Putz, Steffen Haesler +1
Modern smartphones support FIDO2 passwordless authentication using either external security keys or internal biometric authentication, but it is unclear whether users appreciate an…
Safehaul: Risk-Averse Learning for Reliable mmWave Self-Backhauling in 6G Networks
Amir Ashtari Gargari, Andrea Ortiz, Matteo Pagin +4
Wireless backhauling at millimeter-wave frequencies (mmWave) in static scenarios is a well-established practice in cellular networks. However, highly directional and adaptive beamf…
Attacks on Wireless Coexistence: Exploiting Cross-Technology Performance Features for Inter-Chip Privilege Escalation
Jiska Classen, Francesco Gringoli, Michael Hermann +1
Modern mobile devices feature multiple wireless technologies, such as Bluetooth, Wi-Fi, and LTE. Each of them is implemented within a separate wireless chip, sometimes packaged as…
