N2 - In this paper, we analyze the secrecy outage performance for an unmanned aerial vehicle (UAV) -enabled relaying non-orthogonal multiple access (NOMA) system, in which a source transmits a superimposed signal under the NOMA protocol to two users via a UAV-enabled decode-and-forward relay in the presence of an eavesdropper. Assuming the channels experience Nakagami-m fading and both hops are wiretapped, the probability density function (PDF) and cumulative distribution function (CDF) of the instantaneous signal-to-noise ratio are first characterized, and then based on those PDF and CDF expressions, the analytical expressions for secrecy outage probability of two users are derived. Finally, Monte Carlo simulations are used to verify the accuracy of the derived expressions.
