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 …

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 …

Characterized by their ease of deployment and bird's-eye view, unmanned aerial vehicles
(UAVs) may be widely deployed both in surveillance and traffic management. However, the …

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

As a promising paradigm to reduce both capital and operating expenditures, the cloud radio
access network (C-RAN) has been shown to provide high spectral efficiency and energy …

Cognitive radio (CR) and non-orthogonal multiple access (NOMA) have been deemed two
promising technologies due to their potential to achieve high spectral efficiency and massive …

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 …

Quantum secure direct communication (QSDC) is capable of direct confidential
communications over a quantum channel, which is achieved by dispensing with the key …

This paper presents a systematic approach to exploiting TV white space (TVWS) for device-
to-device (D2D) communications with the aid of the existing cellular infrastructure. The goal …

We consider secure resource allocations for orthogonal frequency division multiple access
(OFDMA) two-way relay wireless sensor networks (WSNs). The joint problem of subcarrier …
