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.

Secrecy & Rate Adaptation for secure HARQ protocols [PDF]
2013 IEEE Information Theory Workshop (ITW), 2013 This paper is dedicated to the study of HARQ protocols under a secrecy constraint. An encoder sends information to a legitimate decoder while keeping it secret from the eavesdrop-per. Our objective is to provide a coding scheme that satisfies both reliability and confidentiality conditions.

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.

Information Leakage Rate of Optical Code Division Multiple Access Network Using Wiretap Code
Entropy, 2023 Secrecy capacity is usually employed as the performance metric of the physical layer security in fiber-optic wiretap channels. However, secrecy capacity can only qualitatively evaluate the physical layer security, and it cannot quantitatively evaluate ...

Feasibility of positive secrecy rate in wiretap interference channels [PDF]
2014 IEEE Global Conference on Signal and Information Processing (GlobalSIP), 2014 Interference usually is an adverse phenomenon in wireless networks. However, the interference can potentially be used to boost the secrecy rate in wireless interference channels. This work studies the secrecy rate in a two-user interference network where unintended user may overhear one of the users, namely user 1.

On the Performance of Low-Altitude UAV-Enabled Secure AF Relaying With Cooperative Jamming and SWIPT
IEEE Access, 2019 This paper proposes a novel cooperative secure unmanned aerial vehicle (UAV) aided transmission protocol, where a source sends confidential information to a destination via an energy-constrained UAV-mounted amplify-and-forward relay in the presence of a ...

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.
