Secrecy Analysis and Active Pilot Spoofing Attack Detection for Multigroup Multicasting Cell-Free Massive MIMO Systems

In this paper, we investigate the secure transmission in multigroup multicasting cell-free massive MIMO system in the presence of pilot spoofing attack. With the imperfect uplink and downlink channel estimation, a distributed conjugate beamforming processing with normalized power constraint policy i...
