Secrecy outage probability of DF‐based C‐NOMA under half and full duplex
IET Communications, Volume 17, Issue 19, Page 2188-2199, 1 December 2023., 2023 Cooperative Non‐orthogonal Multiple Access (C‐NOMA) is projected as the dominant technology for 5G and beyond. Also, physical layer security, due to the presence of eaves‐dropper, is a bottleneck security concern for any open link wireless system.

IET Communications, Volume 17, Issue 16, Page 1928-1939, October 2023., 2023 The single‐input multiple‐out (SIMO) system considered is the Wyner eavesdropper model with decoding and forwarding (DF) relay over Beaulieu‐Xie fading. The two performance evaluation indicators of secure outage probability (SOP) and strictly positive secrecy capacity (SPSC) are used to investigate the security performance of the wireless communication

Transmitter selection for secrecy against colluding eavesdroppers with backhaul uncertainty
IET Communications, Volume 17, Issue 14, Page 1741-1759, August 2023., 2023 This manuscript is a research article that deals with the security of a wireless communication network with multiple transmitters having backhaul connections in the presence of eavesdroppers. We evaluate the secrecy performance of the system and describe the numerical results along with the simulation results.

Evaluation of the security performance of artificial noise‐aided STBC systems
IET Communications, Volume 17, Issue 9, Page 1081-1090, June 2023., 2023 In this paper, we evaluate the security performance of artificial noise (AN)‐aided space time block coding (STBC) systems in wiretap channel. We derive a generalized secrecy rate formula for the system utilizing AN‐aided STBC, and also provide an expression for the approximated value with which the estimation time can be highly reduced. In addition, it

IET Signal Processing, Volume 17, Issue 5, May 2023., 2023 In this research, we are using Radio frequency fingerprinting (RF‐FP) for location detection and estimation of vehicles. Based on the acquired estimated location information we observe the effects on secrecy outage probability (SOP) and Secrecy capacity (SC) when a legit source vehicle communicates with a legit destination, in the presence of multiple ...
