Abstract: This paper discusses the problem of securing the transmissions of multipleground users against eavesdropping attacks. We propose and optimize thedeployment of a single unmanned aerial vehicle (UAV), which serves as an aerialrelay between the user cluster and the base station. The focus is on maximizingthe secrecy energy efficiency by jointly optimizing the uplink transmissionpowers of the ground users and the position of the UAV. The joint optimizationproblem is nonconvex; therefore we split it into two subproblems and solve themusing an iterative algorithm.
