Physical Layer Security in Cognitive Untrusted Relay Networks

IEEE Access, 2018
In this paper, we consider the secure communications in a cognitive untrusted relay network, where the secondary source intends to communicate with a secondary destination through an untrusted relay in the presence of the direct source-destination link ...

Achievable Physical-Layer Security Over Composite Fading Channels

IEEE Access, 2020
We investigate the physical layer security limits of Wyner's wiretap model over Fisher-Snedecor .T composite fading channels. .T fading conditions have been recently shown to provide an accurate characterization of multipath fading and shadowing effects ...

Physical layer security in broadcast networks [PDF]

Security and Communication Networks, 2009
AbstractThis paper reviews the information theoretic characterization of security in broadcast channels, in which a transmitter has both public and confidential messages intended for multiple receivers. All messages must be successfully received by their intended receivers, and the confidential messages must be kept as secret as possible from non ...

Physical Encoding in Optical Layer Security

Journal of Cyber Security and Mobility, 2012
Data security at the physical layer of optical networks, or optical layer security, has received considerable research attention due to the rapid growth of optical network capacity [1]. Among various optical layer approaches, optical codedivision multiple access (OCDMA) systems are considered to be promising because of the physical encoding and ...

Physical Layer Security of Hybrid Satellite-FSO Cooperative Systems

IEEE Photonics Journal, 2019
In this paper, we study the physical layer secrecy performance of a hybrid satellite and free-space optical (FSO) cooperative system. The satellite links are assumed to follow the shadowed-Rician fading distribution, and the channel of the terrestrial ...
