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

Physical layer security analysis using radio frequency‐fingerprinting in cellular‐V2X for 6G communication

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 ...

Robust transmission design for artificial noise aided multiuser broadcast system in inaccurate channel state information scenario with users of different importance

IET Communications, Volume 17, Issue 2, Page 171-182, January 2023., 2023
Abstract In this article, robust beamforming (BF) and artificial noise (AN) design method is proposed for multiuser broadcast secure transmission under secrecy outage probability (SOP) constraints. A special scenario is assumed that the transmitter cannot obtain the accurate channel state information (CSI) of the users' channel, and different users ...
