This paper studies the physical (PHY)-layer security performance in full-duplex (FD) multiple- input multipleoutput (MIMO) small-cell networks. Here, we take into account (i) residual self- interference (SI) over Rician fading channels, and (ii) mutual-interference (MI) under successive interference cancellation (SIC) mechanism. Considering linear zero-forcing (ZF) beamforming, the downlink (DL) and uplink (UL) average secrecy rates under both scenarios of passive and colluding eavesdropping are derived. Our findings indicate that the FD functionality can provide substantial improvements in the PHYlayer security performance, especially with the aid of MIMO communications and interference cancellation solutions.
