Non-orthogonal Multiple Access (NOMA) has emerged as a key technique in 5G wireless communication networks. This paper studies physical layer security of a NOMA relaying system with a full-duplex relay. This system suffers from the attack of both an eavesdropper and a jammer. The secrecy outage probability is derived in this paper to characterize the performance system of the considered system. The simulation demonstrates that the secrecy outage probability (SOP) of the system increase when increasing the transmit power of the source, the relay and the jammer. The paper also demonstrates the effect of power allocation and channel gains on the secrecy performance of the system. Keywords: physical layer security, secrecy outage probability, NOMA, full-duplex relaying, 5G wireless networks. Tóm tắt.

“…Due to the open nature of wireless channels, cooperative NOMA systems offer new possibilities and opportunities for security challenge. Recently, emerging as promising solutions to against eavesdropping and guarantee secure transmission, physical layer security techniques have attracted considerable attention and applied in cooperative NOMA systems [12][13][14][15][16][17][18]. In [12], the authors considered both amplify-and-forward (AF) and decode-and-forward (DF) protocols, and derived analytical expressions for secrecy outage probability (SOP) and secrecy capacity.…”

“…The works in [16] analyzed analytical and asymptotical expressions of SOP under both random and max-min relay selection schemes for jammer-aided cooperative NOMA networks. In [17], a multi-antenna full-duplex (FD) relay has been introduced in a cooperative NOMA system with two users, and a full-duplex-jamming (FDJam) scheme has been proposed to guarantee the secure transmission for the user with a weak channel. To increase secrecy rate and reduce information leakage, a new cooperative non-orthogonal jamming decode-and-forward (JDF) scheme has been proposed where the source actively sends jamming signals while the relay is forwarding [18].…”

“…Different from [19,20], a friendly jammer exploiting AN beamforming is employed to disturb multiple eavesdroppers in these considered networks. Specifically, in [16][17][18], the power allocation factor is considered to be fixed in jammer-aided cooperative NOMA networks, while, in this paper, taking both security and performance guarantee into account, an efficient adaptive approach has been developed to obtain the optimal power allocation factor for the secrecy rate maximization. In addition, we define the effective sum rate as the sum rate of the secrecy rate at LU1 and the transmission rate at LU2.…”

In this paper, we investigate cooperative secure transmission in non-orthogonal multiple access (NOMA) networks where a source (Alice) intends to transmit confidential messages to one legitimate user with high-level security requirement (LU1), and serve another normal one (LU2) simultaneously. In order to enhance the transmission security, a cooperative jammer (Charlie) is employed to confuse multiple non-colluding eavesdroppers (Eves). Taking both secrecy outage restriction of LU1 and the desired quality of service (QoS) requirement of LU2 into consideration, we propose an adaptive power allocation strategy for maximizing secrecy rate. Numerical results are provided to validate that our proposed scheme significantly outperforms the conventional NOMA secure transmission scheme.

“…Secrecy capacity, which evaluates the effectiveness of secure transmission, has been defined as the maximum rate in each reliable and secure transmission [5]. This metric has been adopted in the security analysis and optimization of 5G mmWave small cell networks [6], co-operative non-orthogonal multiple access with proactive jamming [7], artificial noise (AN)-aided multi-input multi-output (MIMO) Rician channels [8] and so on. As the secrecy capacity may be less than target secrecy redundancy rate, the secrecy outage probability (SOP) has been applied to present a more comprehensive performance evaluation.…”

In this paper, we studied the secure transmission of a hybrid automatic repeat request with chase combining (HARQ-CC) system, under the existence of multiple eavesdroppers and limited latency. First, we analyzed some critical performance metrics, including connection outage probability (COP), secrecy outage probability (SOP) and effective secrecy throughput (EST). Then, to maximize the EST, three optimization problems of rate adaption were discussed: (i) optimizing the code rate with a given secrecy redundancy rate by a parameterized closed-form solution; (ii) optimizing the secrecy redundancy rate with a given code rate by a fixed-point method; (iii) optimizing both code rate and secrecy redundancy rate by an iterative optimization algorithm. We also considered COP and SOP constraints among the problems while corresponding solutions were deduced. Finally, numerical and simulated results verified our conclusions that the approximated SOP matches well with Monte–Carlo simulation for a strict reliable constraint, and that the optimized transmitting rate enhances EST efficiently with multiple eavesdroppers and retransmissions. Moreover, the influence of the number of eavesdroppers on secrecy performance was analyzed. Briefly, secrecy performance inevitably deteriorates with increasing number of eavesdroppers due to raised information leakage.
