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

Wireless communication provides a wide coverage at the cost of exposing information to
unintended users. As an information-theoretic paradigm, secrecy rate derives bounds for …

The wireless medium offers many opportunities for broadcast communications. However, it
also opens the possibility for attackers to eavesdrop the broadcast data or to pretend to be …

Millimeter-wave (mmWave) wireless communication system allows a compact antenna array
with a large number of colocated elements, which enables flexible array design and …

Theoretical studies on physical layer security often adopt the secrecy outage probability as
the performance metric for wireless communications over quasi-static fading channels. The …

Millimeter-wave large-scale antenna systems typically apply hybrid analog-digital precoders
to reduce hardware complexity and power consumption. In this paper, we design hybrid …

With the large bandwidths available in the terahertz regime, directional transmissions can
exhibit angular dispersion, ie, frequency-dependent radiation direction. Unfortunately …

We design short blocklength codes for the Gaussian wiretap channel under information-
theoretic security guarantees. Our approach consists in decoupling the reliability and …

We design a new relay-aided secure transmission scheme, in which a source communicates
with a destination through a trusted decode-and-forward relay in the presence of spatially …

Designing energy-efficient security techniques for Internet of Things (IoT) networks is
particularly vital due to its limited battery capacity and the flow of information via …
