Reconfigurable Intelligent Surface Assisted Energy Constraint Wireless System under UAV Eavesdropper with Full-Duplex Jammer

—This paper study the security performance of a Reconfigurable Intelligent Surface (RIS) energy constraint wireless system under the presence of Unmanned Aerial Vehicle (UAV) eavesdropper, where a full-duplex jammer destination is powered by a dedicated power beacon. A time switching scheme with full-duplex operation is considered for the legitimate energy constraint destination to generate jamming signal to interfere the eavesdropper. In particular, the analytical closed-form expression of Connection Outage Probability (COP), Security Outage Probability (SOP) and Secrecy Throughput (ST) are derived to evaluate the performance of the proposed system. To achieve more insight about the system, the ST asymptotic expression is obtained. Moreover, the accuracy of the derived analytical expressions is justified by the Monte-Carlo simulation. Our results illustrate that the number of reflecting elements 𝑵 𝑬 , amount of SIC 𝝍 , and fading parameter 𝒎 𝑱𝑬 significantly affect the security performance of the concerned system.
