In this paper, we investigate physical-layer security in a random wireless network where
both legitimate and eavesdropping nodes are randomly deployed. In the first scenario, we …

Recently, the use of artificial noise has attracted considerable attention in enhancing the
physical-layer security of wireless systems. However, the interaction between artificially …

This paper considers the transmission of confidential messages over noisy wireless ad hoc
networks, where both background noise and interference from concurrent transmitters affect …

This paper analyzes the Secrecy Transmission Capacity (STC) over wireless networks,
where the legitimate nodes and eavesdroppers are distributed following Poisson point …

The ability to exchange secret information is critical to many commercial, governmental, and
military networks. Information-theoretic security-widely accepted as the strictest notion of …

This paper studies the achievable secure rate per source-destination pair in wireless
networks. First, a path loss model is considered, where the legitimate and eavesdropper …

The main objective of this book is to investigate the wireless physical layer security in
random cellular networks. Security is a fundamental issue in data communications. In …

Due to the nature of a wireless medium, a wireless channel is susceptible to malicious
nodes, which encourages the consideration of secrecy in many applications such as satellite …

Physical layer secrecy in wireless networks in the presence of eavesdroppers of unknown
location is considered. In contrast to prior schemes, which have expended energy in the …

Wireless physical layer security has attracted great attention in recent years. Although
mobility is an intrinsic property of wireless networks, most of the existing works only consider …
