Pilot Spoofing Attack
Pilot spoofing attack refers to an active attack in wireless networks, where active eavesdroppers (Eves) manipulate the channel estimation to increase the eavesdropping rate. In time division duplex (TDD) systems with channel reciprocity, the downlink channel state information (CSI) can be acquired through uplink channel training. A smart active Eve may hack such channel estimation process by sending an identical pilot sequence to the base station (BS), causing an erroneous channel estimation at the BS and more information leak to the Eve.
