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

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 …

A downlink single-input single-output non-orthogonal multiple access setting is considered,
in which a base station (BS) is communicating with two legitimate users in two possible …

This paper considers a general framework of the wiretap channel with helping interference
and state information (WT-HI-SI), where a transmitter-receiver pair wishes to keep the …

In heterogeneous dense networks where spectrum is shared, users' privacy remains one of
the major challenges. On a multi-antenna relay-assisted multi-carrier interference channel …

Physical layer security is an attractive security mechanism, which exploits the randomness
characteristics of wireless transmission channel to achieve security. However, it is hampered …

A downlink single-input single-output (SISO) non-orthogonal multiple access (NOMA)
system in which a base station (BS) is communicating with two users is considered. An …

Wireless networks have experienced rapid evolutions toward sustainability, scalability and
interoperability. The digital economy is driven by future networked societies to a more …

In a multi‐user wireless network, physical layer security is an important issue, especially
when some of the served users are malicious. As these users actively participate in the …

[en] Wireless broadcast allows widespread and easy information transfer. However, it may
expose the information to unintended receivers, which could include eavesdroppers. As a …
