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 …

The recent development of metasurfaces, which may enable several use cases by modifying
the propagation environment, is anticipated to substantially affect the performance of sixth …

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

We investigate the secrecy transmission of uplink non-orthogonal multiple access (NOMA)
with the aid of energy harvesting (EH) jammers. During each time frame, communication is …

In this article, we consider an intelligent reflecting surface (IRS) assisted Guassian multiple-
input multiple-output (MIMO) wiretap channel (WTC), and focus on enhancing its secrecy …

Key generation from the randomness of wireless channels is a promising alternative to
public key cryptography for the establishment of cryptographic keys between any two users …

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 …

Due to the malicious attacks in wireless networks, physical layer security has attracted
increasing concerns from both academia and industry. The research on physical layer …

The Internet of Things (IoT) is a transformative technology, which is revolutionizing our
everyday life by connecting everyone and everything together. The massive number of …

The Internet of Things (IoT) will feature pervasive sensing and control capabilities via a
