This complete guide to physical-layer security presents the theoretical foundations, practical
implementation, challenges and benefits of a groundbreaking new model for secure …

In this paper, we explore the physical-layer security in cooperative wireless networks with
multiple relays where both amplify-and-forward (AF) and decode-and-forward (DF) protocols …

Physical (PHY) layer security approaches for wireless communications can prevent
eavesdropping without upper layer data encryption. However, they are hampered by …

Pervasive wireless computing and communication have created an ever-increasing demand
for more radio spectrum. Since, most of the spectrum is underutilized, it motivated the …

The fading broadcast channel with confidential messages (BCC) is investigated, where a
source node has common information for two receivers (receivers 1 and 2), and has …

We consider a cognitive radio (CR) network consisting of a secondary transmitter (ST), a
secondary destination (SD) and multiple secondary relays (SRs) in the presence of an …

We consider a cooperative wireless network in the presence of one or more eavesdroppers,
and exploit node cooperation for achieving physical (PHY) layer based security. Two …

Secure communications can be impeded by eavesdroppers in conventional relay systems.
This paper proposes cooperative jamming strategies for two-hop relay networks where the …

We consider the communication scenario where a source-destination pair wishes to keep
the information secret from a relay node despite wanting to enlist its help. For this scenario …

Physical-layer security is emerging as a promising paradigm of securing wireless
communications against eavesdropping between legitimate users, when the main link …
