Pilot Contamination Attack Detection Method Based on OFDM Pilot Signal

Jianqiu Xiong, Chen Xie, Qiao Hu

em>Abstract— Pilot contamination (PC) attack is a well-known active eavesdropping attack. Because of the public transmission protocol, frame structure and pilot sequence set, the eavesdropper (Eve) can send the same pilot as the legitimate user (Bob) to actively affect the channel estimation process at the base station(BS). This results in the contamination of the channel state information (CSI) measured at BS, the alteration of the legitimate beamformer design and information leakage. In this paper, we use the statistical characteristics of the channel to detect whether there is a pilot contamination attack. The secure region is deduced theoretically, which makes the detection of pilot contamination attack more accurate
