报告内容简介：
the pilot spoofing attack is one kind of active eavesdropping conducted by a malicious user during the channel estimation phase of the legitimate transmission. in this attack, an intelligent adversary spoofs the transmitter on the estimation of channel state information (csi) by sending the identical pilot signal as the legitimate receiver, in order to obtain a larger information rate in the data transmission phase. the pilot spoofing attack could also drastically weaken the strength of the received signal at the legitimate receiver if the adversary utilizes large enough power. motivated by the serious problems the pilot spoofing attack could cause, we propose an efficient detector, named energy ratio detector (erd), by exploring the asymmetry of received signal power levels at the transmitter and the legitimate receiver when there exists a pilot spoofing attack. we also propose solutions for recovering secure communications once such attack is identified.
