Effective Secrecy Rate for a Downlink NOMA Network [PDF]
IEEE Transactions on Wireless Communications, 2019 In this paper, a novel approach is introduced to study the achievable delay-guaranteed secrecy rate, by introducing the concept of the effective secrecy rate (ESR). This study focuses on the downlink of a non-orthogonal multiple access (NOMA) network with one base station, multiple single-antenna NOMA users and an eavesdropper.

Virtual full-duplex buffer-aided relay selection schemes for secure cooperative wireless networks
EURASIP Journal on Wireless Communications and Networking, 2022 This paper considers secure communication in buffer-aided cooperative wireless networks in the presence of one eavesdropper, which can intercept the data transmission from both the source and relay nodes.

On the secrecy rate of interference networks using structured codes [PDF]
2009 IEEE International Symposium on Information Theory, 2009 This paper shows that structured transmission schemes are a good choice for secret communication over interference networks with an eavesdropper. Structured transmission is shown to exploit channel asymmetries and thus perform better than randomly generated codebooks for such channels.

Downlink Physical Layer Security Transmission Method Based on Zero-sum Game [PDF]
Jisuanji gongcheng, 2018 In the Multi-downlink network,the interference among nonorthogonal channels and the malicious interference makes destination nodes not meet the demand of Quality of Service(QoS).So a security transmission method based on zero-sum game model is proposed ...

Mobile jammers for secrecy rate maximization in cooperative networks [PDF]
2013 IEEE International Conference on Acoustics, Speech and Signal Processing, 2013 We consider a source (Alice) trying to communicate with a destination (Bob), in a way that an unauthorized node (Eve) cannot infer, based on her observations, the information that is being transmitted. The communication is assisted by multiple multi-antenna cooperating nodes (helpers) who have the ability to move.
