COVERT CHANNEL TECHNIQUE BASED ON STREAMING PROTOCOL [PDF]
Научно-технический вестник информационных технологий, механики и оптики, 2018 The paper presents analysis of modern network covert channels. The authors set forward a hypothesis of effective streaming protocol usage for covert channel creating. Covert channel technique for open networks is proposed.

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.

UAV Relay Assisted Cooperative Jamming for Covert Communications Over Rician Fading
IEEE Transactions on Vehicular Technology, 2022 Covert communication can hide the legitimate transmission from unauthorized eavesdropping. Benefiting from the deployment flexibility, unmanned aerial vehicles (UAVs) can be utilized to enhance communication confidentiality.

Covert Communication in Fading Channels under Channel Uncertainty [PDF]
, 2017 A covert communication system under block fading channels is considered where users experience uncertainty about their channel knowledge. The transmitter seeks to hide the covert communication to a private user by exploiting a legitimate public ...

MD-GAN-Based UAV Trajectory and Power Optimization for Cognitive Covert Communications
IEEE Internet of Things Journal, 2022 This article investigates the covert performance of an unmanned aerial vehicle (UAV) jammer-assisted cognitive radio (CR) network. In particular, the covert transmission of secondary users can be effectively protected by UAV jamming against the ...

Intelligent Reflecting Surface (IRS)-Aided Covert Wireless Communications With Delay Constraint [PDF]
IEEE Transactions on Wireless Communications, 2020 This work examines the performance gain achieved by deploying an intelligent reflecting surface (IRS) in covert communications. To this end, we formulate the joint design of the transmit power and the IRS reflection coefficients by taking into account ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Pediatric patients with extracranial solid tumors (ST) receiving chemotherapy are at an increased risk for Pneumocystis jirovecii pneumonia (PJP). However, evidence guiding prophylaxis practices in this population is limited. A PJP‐related fatality at our institution highlighted inconsistent prescribing approaches and concerns about

A Covert Channel Over VoLTE via Adjusting Silence Periods
IEEE Access, 2018 Covert channels represent unforeseen communication methods that exploit authorized overt communication as the carrier medium for covert messages. Covert channels can be a secure and effective means of transmitting confidential information hidden in overt
