Two-Stage Relay Selection for Enhancing Physical Layer Security in Non-Orthogonal Multiple Access
TL;DR: This paper proposes a novel two-stage secure relay selection with a non-orthogonal multiple access (NOMA) scheme to maximize the capacity of one source-destination pair, while guaranteeing the successful communication of the other source-Destination pair.
Journal ArticleDOI
Robust Cooperative Secure Beamforming for Simultaneous Wireless Information and Power Transfer in Amplify-and-Forward Relay Networks
TL;DR: Simulation results show that the proposed robust scheme achieves better worst-case secrecy rate performance than the other nonrobust schemes and the CB-AN scheme, while it approaches the perfect scheme.
Journal ArticleDOI
Beamforming Design and Power Allocation for Secure Transmission With NOMA
TL;DR: The analysis indicates that it is not optimal to form a beam toward either the strong user or the weak user in NOMA systems for security enhancement, so the optimal power allocation among useful signals and AN is determined together with the two optimal factors in order to maximize the secrecy sum rate (SSR).

Beamforming Design and Power Allocation for Secure Transmission with NOMA
TL;DR: In this article, the authors proposed a novel beamforming design to enhance physical layer security of a NOMA system with the aid of artificial noise (AN), which uses two scalars to balance the useful signal strength and interference at the strong and weak users.
Journal ArticleDOI
TAS-Based Incremental Hybrid Decode–Amplify–Forward Relaying for Physical Layer Security Enhancement
TL;DR: Theoretical analysis and simulation results demonstrate that the proposed TAS-based IHDAF scheme outperforms the selective decode-and-forward, the incremental decode–amplify–forward, and the noncooperative DT schemes in terms of the SOP and effective secrecy throughout, especially when the relay is close to the destination.
