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 …

This letter investigates the secrecy performance of a satellite wiretap channel with multi-user
opportunistic scheduling. By considering some practical effects, such as satellite multi-beam …

Secure communications are becoming increasingly relevant in the development of space
technology. Well-established cryptographic technology is already in place and is expected …

In this paper, we investigate the secrecy performance of radio frequency (RF)
eavesdropping for a high altitude platform station (HAPS) aided satellite communication …

Open nature of wireless networks leads to being sensitive to eavesdropping. Hence, a
tremendous growth of literature has carried out challenges in privacy and security in …

In this paper we propose a two-way protocol of physical layer security using the method of
privacy amplification against eavesdroppers. First we justify our proposed protocol by …
