RF Fingerprinting to Detect Beamstealing Attacks in mmWave 5G Communications [PDF]

Radioengineering
5G 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
