On the Limitation of Covert Channels Bandwidth in IP Networks

open access: yesБезопасность информационных технологий, 2015
Features of packet switching networks and the blanket distribution of high-speed IP networks result in widespread research of covert channels. Adversary’s possibilities used to build covert channels in IP networks were analyzed.

Detection of IP Covert Timing Channels

open access: yesБезопасность информационных технологий, 2015
Covert timing channels became widespread with the increasing popularity of packet switching networks. Detection of these channels is the only approach to counter that does not lead to a decrease of channel’s capacity.

Victim-Aware Adaptive Covert Channels [PDF]

open access: yes, 2019
We investigate the problem of detecting advanced covert channel techniques, namely victim-aware adaptive covert channels. An adaptive covert channel is considered victim-aware when the attacker mimics the content of its victim’s legitimate communication,

Overview of Covert Channel Research in Blockchain Environment [PDF]

open access: yesJisuanji kexue yu tansuo
Covert channel is a method to hide information in public communication channels for covert transmission, aiming at ensuring data transmission security and making third parties unaware of the covert communication process.

Covert channel detection using Information Theory [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2011
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.

Steganalysis of compressed speech to detect covert voice over Internet protocol channels [PDF]

open access: yes, 2011
A network covert channel is a passage along which information leaks across the network in violation of security policy in a completely undetectable manner. This study reveals our findings in analysing the principle of G.723.1 codec that there are `unused'

Reversible and Plausibly Deniable Covert Channels in One-Time Passwords Based on Hash Chains

open access: yesApplied Sciences, 2021
Covert channels enable stealthy communications over innocent appearing carriers. They are increasingly applied in the network context. However, little work is available that exploits cryptographic primitives in the networking context to establish such ...

A Construction Method of Covert Channel Based on File Storage Distribution [PDF]

open access: yesJisuanji gongcheng, 2017
A covert channel construction method based on covert information storage distribution is proposed to solve the problem that the existing reference length covert channels are different from legal channels in the channel entropy and length distribution ...
