A Security Architecture for Railway Signalling
Christian Schlehuber, Markus Heinrich, Tsvetoslava Vateva-Gurova +2
We present the proposed security architecture Deutsche Bahn plans to deploy to protect its trackside safety-critical signalling system against cyber-attacks. We first present the e…
Rule-based Anomaly Detection for Railway Signalling Networks
Markus Heinrich, Arwed Gölz, Tolga Arul +1
We propose a rule-based anomaly detection system for railway signalling that mitigates attacks by a Dolev-Yao attacker who is able to inject control commands and to perform semanti…
Secure Computation of the kth-Ranked Element in a Star Network
Anselme Tueno, Florian Kerschbaum, Stefan Katzenbeisser +2
We consider the problem of securely computing the kth-ranked element in a sequence of n private integers distributed among n parties. The kth-ranked element (e.g., minimum, maximum…
MagneticSpy: Exploiting Magnetometer in Mobile Devices for Website and Application Fingerprinting
Nikolay Matyunin, Yujue Wang, Tolga Arul +3
Recent studies have shown that aggregate CPU usage and power consumption traces on smartphones can leak information about applications running on the system or websites visited. In…
Intrinsic Rowhammer PUFs: Leveraging the Rowhammer Effect for Improved Security
André Schaller, Wenjie Xiong, Nikolaos Athanasios Anagnostopoulos +4
Physically Unclonable Functions (PUFs) have become an important and promising hardware primitive for device fingerprinting, device identification, or key storage. Intrinsic PUFs le…
On (The Lack Of) Location Privacy in Crowdsourcing Applications
Spyros Boukoros, Mathias Humbert, Stefan Katzenbeisser +1
Crowdsourcing enables application developers to benefit from large and diverse datasets at a low cost. Specifically, mobile crowdsourcing (MCS) leverages users' devices as sensors…
