“…In [20], the optimal secrecy performance was achieved with the convex optimization in the FD relay network by using power allocation. A joint relay selection and power allocation scheme was proposed by using the dominant balance to achieve a high secrecy rate in [21].

This paper applies the reinforcement learning in the joint relay selection and power allocation in the secure cognitive radio (CR) relay network, where the data buffers and full-duplex jamming are applied at the relay nodes. Two cases are considered: maximizing the throughput with the delay and secrecy constraints, and maximizing the secrecy rate with the delay constraint, respectively. In both cases, the optimization relies on the buffer states, the interference to/from the primary user, and the constraints on the delay and/or secrecy. This makes it mathematically intractable to apply the traditional optimization methods. In this paper, the double deep Q-network (DDQN) is used to solve the above two optimization problems. We also apply the a-priori information in the CR network to improve the DDQN learning convergence. Simulation results show that the proposed scheme outperforms the traditional algorithm significantly.

“…Therein, based on the performance analysis for the power allocation at the receiver, it was shown that the destination usually does not use all of its available power due to the residual self-interference. Furthermore, different works have analyzed the secrecy performance of FD relaying networks [16]- [19]. For instance, in [16], the SOP of a multiple FD-DF relay network with imperfect channel state information (CSI) was analyzed.…”

“…The authors in [18] proposed an FD jamming relay scheme, which was analyzed in terms of SOP, where the relay simultaneously receives data from the source and sends jamming signals to the eavesdroppers, and then, in a different transmission block, the relay switches to HD mode to retransmit the information to the destination. In [19], the secrecy rates, and optimal power allocation were investigated for a two-hop FD-DF relaying scheme considering static and ergodic fading channels. Moreover, in [20], an FD destination, was considered to enable destination-based jamming in a cooperative network with multiple AF untrusted relays.…”

This paper investigates the secrecy performance of a power splitting-based simultaneous wireless information and power transfer cooperative relay network in the presence of an eavesdropper. The relay is considered to operate in full-duplex (FD) mode to perform both energy harvesting and information decoding simultaneously. To accomplish that, the relay is assumed to employ two rechargeable batteries, which switch between power supplying mode and charging mode at each transmission block. We also assume that the self-interference inherent of the FD mode is not completely suppressed. Therefore, it is assumed that, after some stages of passive and active self-interference cancellation, there is still a residual self-interference (RSI). A portion of this RSI (remaining after passive cancellation) is recycled for energy harvesting. In order to improve the system secrecy performance, it is considered that the relay can split its transmit power to send the information signal and to emit a jamming signal to degrade the eavesdropper's channel. The secrecy performance is evaluated in terms of the secrecy outage probability and the optimal secrecy throughput. Tight-approximate and asymptotic expressions are obtained for the secrecy outage probability, and the particle swarm optimization method is employed for addressing the secrecy throughput optimization problem. From numerical results, we show that the secrecy performance can be increased depending on the self-energy recycling channel condition. Finally, our derived expressions are validated via Monte Carlo simulations.INDEX TERMS Cooperative jamming, full-duplex, physical layer security, relaying, simultaneous wireless information and power transfer.

“…Secrecy cooperation strategies can be broadly categorized as decode-and-forward (DF), amplify-and-Forward (AF), compress-and-forward (CF), and deaf cooperation. The DF scheme requires the relay to decode the source message whose performance mainly relays on the source-relay channel (e.g., [19], [20], [25]- [27]). The AF scheme arranges the relay node to scale and retransmit the received signal (e.g., [25], [28]- [30]).…”

In this paper, we consider the design of a new secure transmission scheme for a four-node relay-eavesdropper channel, where user cooperation is used to facilitate secure communications. The key idea of the proposed achievable scheme is to apply the compression relaying concept of noisy network coding (NNC) to the secrecy communication scenario. But different to the original non-secrecy NNC, the compression rate at the relay is adaptively chosen according to the eavesdropping channel. Particularly, helping interference information is injected into the compression codebook at the relay by simply enlarging the compression rate, which is to effectively suppress the eavesdropping channel. Closed-form expressions of the secrecy rates achieved by the proposed NNC-based secure scheme are characterized for both the discrete memoryless and Gaussian relay-eavesdropper channels, where the optimal compression rate and the optimal transmit power at the relay are also determined. The proposed secure scheme can be viewed as a general framework, which naturally combines the NNC compression relaying scheme with the interference-assisted scheme. Analytical and numerical results demonstrate that the proposed secure scheme offers constant performance gains over typical existing cooperative secure schemes.
