In this work, we present a novel idea to enhance the cybersecurity of a low earth orbit (LEO)
satellite link assuming that the communication between the satellite (Alice) to the ground …

In a day and age where satellite communications are more important than ever to ensure
global communication, establish international military power, and support our everyday way …

The security in satellite communications is a key issue due to the large footprint of the
beams. This is specially critical in IoT devices that transmit data directly to satellite. Take into …

The terrestrial and the non-terrestrial networks have been envisaged to be amalgamated to
form the next generation networks. Further development in wireless communications may …

Satellite communications emerged as a promising extension to terrestrial networks in future
6G network research due to their extensive coverage in remote areas and ability to support …

This paper introduces four proposals to enhance physical layer security (PLS) in low Earth
orbit (LEO) satellite systems. The first proposal leverages the Alamouti code aided by …

In the multi-antenna satellite communication system, beamforming and artificial noise are
usually adopted to enhance physical layer security. However, due to the long distance …

For B5G/6G networks, security will be a critical issue due to data explosion from the launch
of non-terrestrial net-works (NTN) and space-terrestrial integrated networks (STIN). To this …

We develop a novel waveform design approach to minimize the likelihood that a message
transmitted wirelessly between trusted single-antenna nodes is intercepted by an …

The next generation of satellite constellations would include low Earth orbit (LEO) satellites
with communication link above 100 GHz in order to achieve higher efficiency and capacity of …
