Physical Layer Security through Secure Channel Estimation

2018 IEEE 87th Vehicular Technology Conference (VTC Spring), 2018
The random nature of wireless channel can be utilized to achieve secure communications. Recently, there have been some contributions towards finding practical approaches to provide physical layer security, but robust and secure channel estimates are critical in achieving secrecy.

Physical Layer Security in Random NOMA-Enabled Heterogeneous Networks

IEEE Open Journal of the Communications Society
The performance of physical layer secrecy approach in non-orthogonal multiple access (NOMA)-enabled heterogeneous networks (HetNets) is analyzed in this paper. A K-tier multi-cell HetNet is considered, comprising NOMA adopted in all tiers.

Caching-Aided Physical Layer Security in Wireless Cache-Enabled Heterogeneous Networks

IEEE Access, 2018
Caching popular contents is a promising way to offload the mobile data traffic in wireless networks, but so far the potential advantage of caching in improving physical layer security (PLS) is rarely considered. In this paper, we contribute to the design

RIS-assisted Physical Layer Security

CoRR
We propose a reconfigurable intelligent surface (RIS)-assisted wiretap channel, where the RIS is strategically deployed to provide a spatial separation to the transmitter, and orthogonal combiners are employed at the legitimate receiver to extract the data streams from the direct and RIS-assisted links.
