Performance Analysis for UAV-Jammer Aided Covert Communication
IEEE Access, 2020 This paper investigates the performance analysis for a novel covert communication system, where a friendly UAV-jammer is used to protect the covert transmission from Alice to Bob against the eavesdropping from Dave.

Behavioral Mimicry Covert Communication [PDF]
, 2012 In this paper, the use of structural behavior of communication protocols (e.g., CSMA) in designing new covert channels is investigated. In this way, the covert transmitter adopts the communication protocol architecture to control its overt traffic flow yet with different parameters that give it enough freedom to embed the covert message in its overt ...

Advanced Functional Materials, EarlyView.This work develops 3D‐printable tribopolymer networks that can enhance triboelectric performance under high humidity environments. Polar hydrophilic functional groups and incorporation of zwitterionic monomers promote bound‐water–dominated interfacial polarization thereby increasing electrical outputs.

Adversarial Attack for Deep Steganography Based on Surrogate Training and Knowledge Diffusion
Applied Sciences, 2023 Deep steganography (DS), using neural networks to hide one image in another, has performed well in terms of invisibility, embedding capacity, etc. Current steganalysis methods for DS can only detect or remove secret images hidden in natural images and ...

Covert channel detection using Information Theory
, 2010 This paper presents an information theory based detection framework for covert channels. We first show that the usual notion of interference does not characterize the notion of deliberate information flow of covert channels.

Advanced Healthcare Materials, EarlyView.Neural cell–derived small extracellular vesicles (sEVs) are emerging as pivotal mediators in neurodegenerative diseases, exerting both pathogenic and therapeutic functions. This review synthesizes current evidence on how sEVs from distinct neural cell types regulate neurodegeneration, neuroprotection, biomarker discovery, and targeted drug delivery ...
