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 …

Physical Layer Security (PLS) is widely recognized as a promising approach to secure
wireless communications through the exploitation of the physical properties of the wireless …

We analyze the physical layer security of a communication scheme with a multiple antenna
legitimate transmitter, employing transmit antenna selection (TAS), and a single antenna …

We analyze the physical layer (PHY) security of a communication scheme consisting of a
multiple antenna transmitter with a single radio frequency (RF) chain using transmit antenna …

This paper proposes a physical-layer security scheme for wireless networks, aiming to
achieve communication secrecy by making the eavesdropper incapable of decoding the …

We propose a novel physical layer scheme to suppress eavesdropping. Different from the
existing schemes which are based on secrecy rate enhancement with Gaussian signal, our …

In this paper we consider the problem of secure communication between two nodes, over a
fading wireless medium, in the presence of a passive eavesdropper. We propose a scheme …

The intrinsic broadcast nature of wireless communication let the attackers to initiate several
passive attacks such as eavesdropping. In this attack, the attackers do not disturb/stop or …

This paper studies physical-layer secure transmissions from a transmitter to a legitimate
receiver against an eavesdropper over slow fading channels, taking into account the impact …

Physical layer security, or information-theoretic security, has attracted considerable attention
recently, due to its potential to enhance the transmission secrecy of wireless …
