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

Due to the broadcast nature of radio propagation, the wireless air interface is open and
accessible to both authorized and illegitimate users. This completely differs from a wired …

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 …

Nonorthogonal multiple access (NOMA) assisted semi-grant-free transmission admits grant-
free users to access the channels otherwise solely occupied by grant-based users, and has …

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

Research and processing development on satellite communications has strongly re-
emerged in recent years. Following the prosperity of various wireless services provided by …

This paper investigates the physical layer security of a satellite network, whose downlink
spectral resource is shared with a terrestrial cellular network. We propose to employ a multi …

Device-to-device (D2D) communication presents a new paradigm in mobile networking to
facilitate data exchange between physically proximate devices. The development of D2D is …

In this correspondence, we investigate the physical layer security for cooperative
nonorthogonal multiple access (NOMA) systems, where both amplify-and-forward (AF) and …

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 …
