We consider the use of physical-layer security in a wireless communication system where
multiple jamming nodes assist multiple source-destination nodes in combating unwanted …

In wireless communications, the physical layer security is an emerging security research
area that explores the possibilities of achieving high secrecy data transmission between …

1 A wireless communication network is considered, consisting of a source, a destination and
an eavesdropper, each equipped with a single antenna. The communication is assisted by …

Physical layer security is an emerging security area that achieves perfect secrecy data
transmission between intended network nodes, while malicious nodes that eavesdrop the …

Cooperative jamming is an approach that has been recently proposed for improving
physical layer based security for wireless networks in the presence of an eavesdropper …

Secure relay and jammer selection for physical-layer security is studied in a wireless
network with multiple intermediate nodes and eavesdroppers, where each intermediate …

This paper considers a friendly interferer allocating jamming power to eavesdropping
channels to increase the level of secrecy of a wireless network. The friendly interferer has …

This paper studies the secrecy rate maximization problem of a secure wireless
communication system in the presence of multiple eavesdroppers. The security of the …

Wireless networks are increasingly being employed to transfer highly sensitive information.
Due to the broadcast nature of wireless channels, security issues have been taken as a …

Secrecy transmission is investigated for a cooperative jamming scheme, where a multi-
antenna jammer generates artificial noise (AN) to confuse eavesdroppers. Two kinds of …
