RF Fingerprinting to Detect Beamstealing Attacks in mmWave 5G Communications [PDF]
Radioengineering5G mmWave networks rely on directional beamforming to ensure high-bandwidth connectivity, but the initial beam alignment process is vulnerable to beam-stealing attacks. In this scenario, an adversary transmits forged synchronization signals to hijack the

Reconfigurable Antennas in mmWave MIMO Systems
CoRR, 2017 The key obstacle to achieving the full potential of the millimeter wave (mmWave) band has been the poor propagation characteristics of wireless signals in this band. One approach to overcome this issue is to use antennas that can support higher gains while providing beam adaptability and diversity, i.e., reconfigurable antennas.
