Physical layer security (PLS) has emerged as a new concept and powerful alternative that
can complement and may even replace encryption-based approaches, which entail many …

Physical layer security (PHY-security) takes the advantages of channel randomness nature
of transmission media to achieve communication confidentiality and authentication. Wiretap …

Due to the broadcast nature of radio propagation, the wireless air interface is open and
accessible to both authorized and illegitimate users. This completely differs from a wired …

The Internet of Things (IoT) is a transformative technology, which is revolutionizing our

This paper provides a comprehensive review of the domain of physical layer security in
multiuser wireless networks. The essential premise of physical layer security is to enable the …

Two legitimate parties, referred to as Alice and Bob, wish to generate secret keys from the
wireless channel in the presence of an eavesdropper, referred to as Eve, in order to use …

Cognitive radio (CR) is regarded as an emerging technology, which equips wireless devices
with the capability to adapt their operating parameters on the fly based on the radio …

This paper studies the secure beamforming design in a multiple-antenna three-node system
where two source nodes exchange messages with the help of an untrusted relay node. The …

This paper investigates the performance of key generation between two nodes assisted by a
relay in the presence of correlated eavesdropping channels. A cooperative jamming scheme …

In this paper, we propose a physical-layer secret key generation scheme for multiantenna
legitimate nodes with the help of multiple untrusted relays, equipped with multiple antennas …
