Physical layer security (PLS) has emerged as a new concept and powerful alternative that
can complement and may even replace encryption-based approaches, which entail many …

Physical layer security (PHY-security) takes the advantages of channel randomness nature
of transmission media to achieve communication confidentiality and authentication. Wiretap …

Covert communications hide the transmission of a message from a watchful adversary while
ensuring a certain decoding performance at the receiver. In this paper, a wireless …

The evolving explosion in high data rate services and applications will soon require the use
of untapped, abundant unregulated spectrum of the visible light for communications to …

This paper provides a comprehensive review of the domain of physical layer security in
multiuser wireless networks. The essential premise of physical layer security is to enable the …

In this paper, we study delay-intolerant covert communications in additive white Gaussian
noise (AWGN) channels with a finite block length, ie, a finite number of channel uses …

Prior studies on covert communication with noise uncertainty adopted a worst-case
approach from the warden's perspective. That is, the worst-case detection performance of …

This paper proposes a new design of non-orthogonal multiple access (NOMA) under
secrecy considerations. We focus on a NOMA system, where a transmitter sends confidential …

Covert wireless communication aims to hide the very existence of wireless transmissions in
order to guarantee a strong security in wireless networks. In this paper, we examine the …

This paper considers improving the confidentiality of visible light communication (VLC) links
within the framework of physical-layer security. We study a VLC scenario with one …
