Abstract：

Non-orthogonal　multiple　access　(NOMA)　has　been　recognized　as　a　promising　technique　for　providing　high　data　rates　in　5G　systems.　This　letter　is　to　study　physical　layer　security　in　a　single-input　single-output　(SISO)　NOMA　system　consisting　of　a　transmitter,　multiple　legitimate　users　and　an　eavesdropper.　The　aim　of　this　letter　is　to　maximize　the　secrecy　sum　rate　(SSR)　of　the　NOMA　system　subject　to　the　users＇　quality　of　service　(QoS)　requirements.　We　firstly　identify　the　feasible　region　of　the　transmit　power　for　satisfying　all　users＇　QoS　requirements.　Then　we　derive　the　closed-form　expression　of　an　optimal　power　allocation　policy　that　maximizes　the　SSR.　Numerical　results　are　provided　to　show　a　significant　SSR　improvement　by　NOMA　compared　with　conventional　orthogonal　multiple　access　(OMA).
