The concept of physical layer security builds on the pivotal idea of turning the channel's
imperfections, such as noise and fading, into a source of security. This is established …

This paper develops a tractable framework for exploiting the potential benefits of physical
layer security in three-tier wireless sensor networks (WSNs) using stochastic geometry. In …

Transmit antenna selection (TAS) in wiretap channels has arisen as a simple promising
scheme to improve physical layer security. However, up to now, TAS schemes have aimed …

We investigate large wireless networks subject to security constraints. In contrast to point-to-
point, interference-limited communications considered in prior works, we propose active …

This paper proposes a novel usage of zero-forcing beamforming (ZFB) for secure
transmission in multiple-input single-output (MISO) wiretap channels. When using ZFB for …

One major challenge in physical layer security for confidential communication is the lack of
channel state information at the transmitter about the channel to the passive eavesdropper …
