Security has always played a critical role in wireless cooperative communication systems
design. Eavesdropping and jamming are two common threats to the information security in …

In this paper, we pioneer the study of physical-layer security in heterogeneous networks
(HetNets). We investigate secure communications in a two-tier downlink HetNet, which …

Leveraging a wireless multipath channel as the source of common randomness, many key
generation methods have been proposed according to the information-theory security …

Due to the openness of wireless communication, information transmitted in the multiple
access channel is vulnerable to eavesdropping by illegitimate users. Classic artificial noise …

This study investigates the security of the two‐way relaying system with untrusty relay nodes.
Cooperative jamming schemes are considered for bi‐directional secrecy communications …

Frequency jamming is the fiercest attack tool to disrupt wireless communication and its
malicious aspects have received much attention in the literature. Yet, several recent works …

We present achievable scaling results on the per-node secure throughput that can be
realized in a large random wireless network of n legitimate nodes in the presence of m …

There is a rich recent literature on information-theoretically secure communication at the
physical layer of wireless networks, where secret communication between a single …

Service Oriented Computing (SOC) has initially developed for the Internet, but also identified
as an appealing computing paradigm for developing applications in distributed wireless …

Wireless communications nowadays are increasingly becoming irreplaceable networking
technologies for military, governmental and financial communications where the data is …
