This paper presents a new encryption scheme implemented at the physical layer of wireless
networks employing orthogonal frequency-division multiplexing (OFDM). The new scheme …

Cooperative jamming is deemed as a promising physical layer-based approach to secure
wireless transmissions in the presence of eavesdroppers. In this paper, we investigate …

Wireless physical layer security has attracted great attention in recent years. Although
mobility is an intrinsic property of wireless networks, most of the existing works only consider …

This paper investigates the secrecy outage performance of transmit antenna selection
(TAS)/maximal ratio combining (MRC) in multiple-input-multiple-output (MIMO) cognitive …

This article presents a framework for converting wireless signals into structured datasets,
which can be fed into machine learning algorithms for the detection of active eavesdropping …

Aeronautical communications still heavily depend on analog radio systems, despite the fact
that digital communication has been introduced to aviation in the 1990's. Since then, the …

We consider remote state estimation in the presence of an active eavesdropper. A sensor
forward local state estimates to a remote estimator over a network, which may be …

In recent years, there have been increasing demands for the security of wireless multimedia
applications. Essentially, wireless networks, compared to traditional wired networks, are …

Providing secure communications over the physical layer with the objective of achieving
secrecy without requiring a secret key has been receiving growing attention within the past …

In this work, we propose a new transmit antenna selection (TAS) scheme which examines
the trade-off between feedback overhead and secrecy performance in multiple-input multiple …
