Pilot contamination for active eavesdropping

Zhou, Xiangyun; Maham, Behrouz; Hjørungnes, Are


Abstract—Existing studies on physical layer security often assume the availability of perfect channel state information (CSI) and overlook the importance of channel training needed for obtaining the CSI. In this letter, we discuss how an active eavesdropper can attack the training phase in wireless communication to improve its eavesdropping performance. We derive a new security attack from the pilot contamination phenomenon, which targets at systems using reverse training to obtain the CSI at...[Show more]
