DOI: 10.1109/access.2018.2796075

Abstract: In this paper, we investigate the worst-case robust secure precoding design for simultaneous wireless information and power transfer in multiple-input-multiple-output wiretap system, which consists of one transmitter, one information receiver, and one energy receiver. By… read more here.

DOI: 10.1109/tcomm.2020.3048351

Abstract: The secrecy capacity based on the assumption of having continuous distributions for the input signals constitutes one of the fundamental metrics for the existing physical layer security (PHYS) solutions. However, the input signals of real-world… read more here.

DOI: 10.1109/tifs.2020.3016836

Abstract: Based on the concept of constructive interference (CI), multiuser interference (MUI) has recently been shown to be beneficial for communication secrecy. A few CI-based secure precoding algorithms have been proposed that use both the channel… read more here.

recommendations! Published in 2024 at "IEEE Transactions on Vehicular Technology"

DOI: 10.1109/tvt.2024.3349686

Abstract: The wide coverage and broadcasting characteristics of satellite communications lead to multi-beam downlinks being vulnerable to security threats, such as eavesdropping, hacking and illegal access. This article takes into account the case of multiple users… read more here.
