The vulnerability of cellular networks to location-based attacks via uplink timing management commands has been studied since the advent of GSM. However, the introduction of heterogenous networks as the answer to increasing demand for data throughput has resulted in a new vulnerability to such attacks. In this work, we propose Cellular Synchronization Assisted Refinement (CeSAR), an entirely passive...
Inferring user equipment (UE) location in cellular networks via uplink timing management presents attractive possibilities in an increasingly mobile-connected world. Power constrained mobile devices with ever more common applications that rely on location-based services demand an alternate solution to positioning than a Global Navigation Satellite System (GNSS) and its derivatives. In this paper we...
