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

Interference is traditionally viewed as a performance limiting factor in wireless
communication systems, which is to be minimized or mitigated. Nevertheless, a recent line of …

Physical layer security which safeguards data confidentiality based on the information-
theoretic approaches has received significant research interest recently. The key idea …

Channel estimation is challenging for the reconfigurable intelligent surface (RIS)-aided
wireless communications. Since the number of coefficients of the cascaded channel among …

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 …

In this paper, we study resource allocation design for secure communication in intelligent
reflecting surface (IRS)-assisted multiuser multiple-input single-output (MISO) …

Full-duplex (FD) communication is a potential game changer for future wireless networks. It
allows for simultaneous transmit and receive operations over the same frequency band, a …

Wireless networks with their ubiquitous applications have become an indispensable part of
our daily lives. Wireless networks demand more and more spectral resources to support the …

We investigate the impact of cochannel interference on the security performance of multiple
