Physical Layer Security in Cognitive Untrusted Relay Networks

IEEE Access, 2018
In this paper, we consider the secure communications in a cognitive untrusted relay network, where the secondary source intends to communicate with a secondary destination through an untrusted relay in the presence of the direct source-destination link ...

Secure Transmission Design for Cooperative NOMA in the Presence of Internal Eavesdropping [PDF]

, 2022
The application of successive interference cancellation (SIC) introduces critical security risks to cooperative non-orthogonal multiple access (NOMA) systems in the presence of untrustworthy network nodes, referred to as internal eavesdroppers.

The Security of Practical Quantum Key Distribution [PDF]

, 2009
Quantum key distribution (QKD) is the first quantum information task to reach the level of mature technology, already fit for commercialization. It aims at the creation of a secret key between authorized partners connected by a quantum channel and a ...

Optimization of Code Rates in SISOME Wiretap Channels

, 2015
We propose a new framework for determining the wiretap code rates of single-input single-output multi-antenna eavesdropper (SISOME) wiretap channels when the capacity of the eavesdropper's channel is not available at the transmitter.

Physical Layer Security in an Untrusted Energy Harvesting Relay Network

IEEE Access, 2019
The security performance in an amplify-and-forward dual-hop untrusted relay network is considered. It is assumed that the source and multiple destinations are equipped with multiple antennas, and the information transmission is aided by a single-antenna ...

Info-Clustering: A Mathematical Theory for Data Clustering

, 2016
We formulate an info-clustering paradigm based on a multivariate information measure, called multivariate mutual information, that naturally extends Shannon's mutual information between two random variables to the multivariate case involving more than ...

Effects of selective harvest on antler size of white‐tailed deer in Texas, USA

Wildlife Monographs, EarlyView.
We conducted 20 years of experiments on the selective harvest of white‐tailed deer by antler size, judged inferior, in 2 areas of South Texas, USA. Selective harvest increased the phenotypic antler size of older males in one study area but not the other. There was little evidence of evolution resulting from selective harvesting. Abstract There has been

Plant Variety Registration in Transition: Opportunities for Innovation and Reform in The European Union Enregistrement des variétés végétales en transition : opportunités d’innovation et de réforme dans l’Union européenne Die Registrierung von Pflanzensorten im Wandel: Chancen für Innovation und Neugestaltung in der Europäischen Union

EuroChoices, EarlyView.
Summary Modernising the European Union’s plant variety registration system is critical to enabling the development and adoption of sustainable, climate‐resilient varieties aligned with the EU Farm‐to‐Fork Strategy. However, the current system is outdated and under increasing pressure. While legislative reform is underway, key points of divergence among

Unravelling polyphenol skin permeation: A comparative study using full‐thickness 3D in vitro and ex vivo human skin models

International Journal of Cosmetic Science, EarlyView.
This study demonstrates that full‐thickness 3D in vitro skin models reliably assess the permeation of cosmetic polyphenols, revealing compound‐specific transport profiles and bridging the gap between conventional cell models and ex vivo human skin, while offering an ethical and robust alternative for dermal absorption screening. Abstract The evaluation
