Physical layer security has recently become an emerging technique to complement and
significantly improve the communication security of wireless networks. Compared to …

This article provides a comprehensive overview on jamming strategies in the physical layer
for securing wireless communications. As a complement to traditional cryptography-based …

In conventional physical layer security schemes no leakage of private information to
adversary nodes is tolerated, and no assumption on the encryption of information is …

The inherent open nature of the transmission medium makes security a challenging issue in
wireless networks. Physical layer security, which is an alternative or a complement to the …

We consider the problem of secure communications over the two-way wiretap channel
under a strong secrecy criterion. We improve existing results by developing an achievable …

We analyze and optimize the secrecy performance of artificial noise (AN) in multi-input
single-output wiretap channels with multiple antennas at the transmitter and a single …

A common approach for introducing security at the physical layer is to rely on the channel
variations of the wireless environment. This type of approach is not always suitable for …

In the current digital world, secrecy and privacy are predominant challenges in Wireless
communication networks. Physical Layer Security (PLS) is an emerging research domain …

Wireless networks have become imperative in all areas of human life. As such, one of the
most critical concerns in next-generation networks is ensuring the security and privacy of …

The wiretap channel model in a wireless scenario is analyzed where there is a transmitter,
multiple legitimate receivers, non-colluding and colluding eavesdroppers; each of them is …
