Securing Downlink Massive MIMO-NOMA Networks with Artificial Noise
, 2019 In this paper, we focus on securing the confidential information of massive multiple-input multiple-output (MIMO) non-orthogonal multiple access (NOMA) networks by exploiting artificial noise (AN). An uplink training scheme is first proposed with minimum

On the Secrecy Performance of SWIPT Receiver Architectures with Multiple Eavesdroppers [PDF]
Wireless Communications and Mobile Computing, 2018 Physical layer security (PLS) has been shown to hold promise as a new paradigm for securing wireless links. In contrast with the conventional cryptographic techniques, PLS methods exploit the random fading in wireless channels to provide link security.
