Satellite communications and reconfigurable intelligent surface (RIS) are considered as two
promising technologies that can significantly improve the coverage and energy efficiency of …

Physical layer security (PLS) technologies are expected to play an important role in the next-
generation wireless networks, by providing secure communication to protect critical and …

In this paper, we propose an intelligent reflecting surface (IRS) empowered secure
cooperative transmission strategy for satellite-terrestrial integrated networks. In such …

Due to the constraints on power supply and limited encryption capability, data security
based on physical layer security (PLS) techniques in backscatter communications has …

The long distance characteristic of satellite transmission makes it difficult to achieve secure
communication due to the highly correlated channels. This letter investigates secure satellite …

The ultra-dense low earth orbit (LEO) integrated satellite-terrestrial networks (UDLEO-ISTN)
can bring lots of benefits in terms of wide coverage, high capacity, and strong robustness …

To implement secure communication among similar channels for satellite communications, a
secure communication model based on collaboration with the interference relay of the …

The satellite‐terrestrial downlink transmissions with larger coverage areas face more severe
security challenges than terrestrial cellular communications due to the limitation of the …

The issues of the physical layer security are studied, where one transmitter (Alice), one full‐
duplex (FD) legitimate receiver (Bob) and one multi‐antenna jammer (Charlie) are …

In this paper, a secure multiuser MISO satellite downlink communication system is
considered with the assist of a hybrid reconfigurable intelligent surface (RIS). A robust …
