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

As a complement to high-layer encryption techniques, physical layer security has been
widely recognized as a promising way to enhance wireless security by exploiting the …

Physical layer security (PLS) has been extensively explored as an alternative to
conventional cryptographic schemes for securing wireless links. Many studies have shown …

Due to the malicious attacks in wireless networks, physical layer security has attracted

In this paper, we explore the physical-layer security in cooperative wireless networks with
multiple relays where both amplify-and-forward (AF) and decode-and-forward (DF) protocols …

The wireless physical-layer identification (WPLI) techniques utilize the unique features of the
physical waveforms of wireless signals to identify and classify authorized devices. As the …

The Internet of Things (IoT) depicts a bright future, where any devices having sensorial and
computing capabilities can interact with each other. Among all existing technologies, the …

This letter proposes several relay selection policies for secure communication in cognitive
decode-and-forward relay networks, where a pair of cognitive relays is opportunistically …

In this paper, we study different secrecy rate optimization techniques for a multiple-input–
multiple-output (MIMO) secrecy channel, where a multiantenna cooperative jammer is …

In this paper, we develop a non-orthogonal multiple access (NOMA)-based two-way relay
network with secrecy considerations, in which two users wish to exchange their NOMA …
