IRS-aided Communication Systems in the Presence of Multiple Eavesdroppers

Abstract

In this study, the performance analysis of secrecy capacity and secrecy outage probability in the presence of multiple eavesdroppers that cooperate (colluding) and do not cooperate (non-colluding) with each other, respectively, is studied for the intelligent reflective surfaces (IRS) assisted communication system model in urban wireless networks. In both approaches, realistic security problems and solutions regarding the system model related to physical layer security for legitimate users, designed with the help of the IRS, are evaluated.
