The physical layer security of uplink non-orthogonal multiple access (NOMA)is analyzed. A stochastic geometry approach is applied to analyze the coverageprobability and the effective secrecy throughput (EST) of the kth NOMA user,where a fixed or an adaptive transmission rate can be used. A protected zonearound the legitimate terminals to establish an eavesdropper-exclusion area. Weassume that the channel state information associated with eavesdroppers is notavailable at the base station. We consider that the base station is equippedwith multiple antennas. The impact of imperfect successive interferencecancellation is also taken into account in this work. Our analysis allows aneasy selection of the wiretap code rates that maximizes the EST. Additionally,our framework also allows an optimum selection of other system parameters likethe transmit power or the eavesdropper-exclusion radius.
