SnapCatch: Automatic Detection of Covert Timing Channels Using Image Processing and Machine Learning

open access: yesIEEE Access, 2021
With the rapid growth of data exfiltration carried out by cyber attacks, Covert Timing Channels (CTC) have become an imminent network security risk that continues to grow in both sophistication and utilization.

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.

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.

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 ...

An Insight to Covert Channels

open access: yesCoRR, 2013
This paper presents an overview of different concepts regarding covert channels. It discusses the various classifications and the detailing of various fields used to manipulate for the covert channel execution.Different evaluation criterias are presented for measuring the strength of covert channels.

On the computation of covert channel capacity [PDF]

open access: yesRAIRO - Theoretical Informatics and Applications, 2010
The paper deals with the bitrates (or capacity) of covert channels that is to say systems which allow unidirectional communication between a sender and a receiver. One first defines what is meant by covert channels, and then the basic properties of bitrates are displayed. Then one provides various techniques which can be used to obtain lower bounds for

Mice and Covert Channels

open access: yesCoRR, 2019
Any secure network is only as secure as its weakest component. With overt channels tightly secured and attackers have started focusing on optical, audible, magnetic, and thermal covert channels to access sensitive systems. In this paper, we present a novel, reliable and bidirectional optical covert channel which uses optical mice.

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 ...
