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

Secrecy Performance of Mobile Image Transmission Networks [PDF]
Proceedings of the 11th EAI International Conference on Mobile Multimedia Communications, 2018 Due to the user mobility, the physical layer security of mobile image transmission networks is an important challenging task.In this paper, based on the classic Wyner wiretap model, the secrecy performance of mobile image transmission networks is investigated. We derive exact closed-form expressions for the average secrecy capacity (ASC).

On the Secrecy Performance of Land Mobile Satellite Communication Systems
IEEE Access, 2018 In this paper, we investigate the secrecy performance against eavesdropping of a land mobile satellite (LMS) system, where the satellite employs the spot beam technique, and both the terrestrial user and eavesdropper are equipped with multiple antennas and utilize maximal ratio combining to receive the confidential message.
