Secrecy Analysis of Control Information for UAV [PDF]

, 2023
In this correspondence, we investigate the average achievable secrecy rate (AASR) and average effective secrecy throughput (AEST) of the control link from the ground control station to the unmanned aerial vehicle (UAV), which requires ultra-reliable and ...

Enhancing Physical Layer Security of DF Buffer-Aided Relay Networks With Small Buffer Sizes

IEEE Access, 2019
In this paper, we propose a novel max-weight secure link selection (MWSLS) scheme to enhance physical layer security of decode-and-forward (DF) buffer-aided relay networks. The MWSLS scheme can select the link with the largest weight among all secure and

ZF-SIC Based Individual Secrecy in SIMO Multiple Access Wiretap Channel

IEEE Access, 2017
In this paper, a decoding method of joint zero-forcing and successive interference cancellation (ZF-SIC) is put forward to assist the study of the individual secrecy in the quasi-static Rayleigh fading single-input multiple-output multiple access wiretap

Secure Transmission for Differential Quadrature Spatial Modulation With Artificial Noise

IEEE Access, 2019
In this paper, we investigate the secure transmission for differential quadrature spatial modulation (DQSM) with artificial noise (AN) in multiple-input single-output wiretap networks, where a cooperative jammer helps the secure transmission between ...

Secrecy Enhancement of Multiuser MISO Networks Using OSTBC and Artificial Noise [PDF]

, 2017
In this paper, we propose a novel physical layer strategy to improve the secrecy performance of multiuser multiple-input single-output networks. In this strategy, orthogonal space-time block code (OSTBC) is employed at an AAantenna base station (BS ...

Secure Transmission Design for Cooperative NOMA in the Presence of Internal Eavesdropping [PDF]

, 2022
The application of successive interference cancellation (SIC) introduces critical security risks to cooperative non-orthogonal multiple access (NOMA) systems in the presence of untrustworthy network nodes, referred to as internal eavesdroppers.

Secrecy analysis in NOMA full-duplex relaying networks with artificial jamming

, 2021
Non-orthogonal multiple access (NOMA) is an important technology for the forthcoming 5G and beyond. However, its privacy often suffers from adversarial eavesdropping, especially for the users with higher transmit power.
