NEL: a tool for a Network Environment Learning Phase

We just released the first public tool that implements a so-called Network Environment Learning (NEL) phase for covert channels. This tool aims to support researchers in the domain of Network Steganography. More information:

Information Hiding + Science 2.0

In a new paper, we discuss how Information Hiding can be combined with Science 2.0/Open Science.

Steffen Wendzel, Luca Caviglione, Wojciech Mazurczyk, Jean-Francois Lalande:
Network Information Hiding and Science 2.0: Can it be a Match?,
Int. Journal of Electronics and Telecommunications, Vol. 63(2), pp. 217-222, 2017.

Science 2.0 aims at using the information sharing and collaborative features of the Internet to offer new features to the research community. Science 2.0 has been already applied to computer sciences, especially bioinformatics. For network information hiding, a field studying the possibility of concealing a communication in networks, the application of Science 2.0 is still a rather uncovered territory. To foster the discussion of potential benefits for network information hiding, we provide a disquisition for six different Science 2.0 aspects when applied to this domain.

This project is now also on ResearchGate

We performed some tiny updates on the content to provide a better explanation of our approach.

Another update is that you can now follow our project on ResearchGate. (All information is also and primarily available on this website, i.e. following our blog will provide you with at least the same information as you will get on ResearchGate.)

New Publication: Unified Description for Network Information Hiding Methods

We published a new paper related to network information hiding patterns. This time, we provide a way for a unified description of hiding methods (hiding techniques). In other words: if a new hiding technique must be described in a scientific paper, so that it can be published, we propose a clear structure for the description of the new technique.

S. Wendzel, W. Mazurczyk, S. Zander: Unified Description for Network Information Hiding Methods, Journal of Universal Computer Science (J.UCS), Vol. 22(11), 2016.

Until now hiding methods in network steganography have been described in arbitrary ways, making them difficult to compare. For instance, some publications describe classical channel characteristics, such as robustness and bandwidth, while others describe the embedding of hidden information. We introduce the first unified description of hiding methods in network steganography. Our description method is based on a comprehensive analysis of the existing publications in the domain. When our description method is applied by the research community, future publications will be easier to categorize, compare and extend. Our method can also serve as a basis to evaluate the novelty of hiding methods proposed in the future.

CCEAP 0.5.0 released!

The Covert Channel Education tool CCEAP was released in v.0.5.0 today, including support for two new hiding patterns: `Inter-arrival Time' and 'Rate/Throughput'.

CCEAP will be presented during a poster presentation at ACM CCS in Vienna next week.

New Publication: An Educational Network Protocol for Covert Channel Analysis Using Patterns

A new short paper (poster) on pattern-based information hiding was accepted at this year's ACM CCS conference in Vienna, Austria:

Steffen Wendzel and Wojciech Mazurczyk: POSTER: An Educational Network Protocol for Covert Channel Analysis Using Patterns, in Proc. 23rd ACM Conference on Computer and Communications Security (CCS 2016), 2016.

Abstract: The utilization of information hiding is on the rise among cybercriminals, e.g. to cloak the communication of malicious software as well as by ordinary users for privacy-enhancing purposes. A recent trend is to use network traffic in form of covert channels to convey secrets. In result, security expert training is incomplete if these aspects are not covered.
This paper fills this gap by providing a method for teaching covert channel analysis of network protocols. We define a sample protocol called Covert Channel Educational Analysis Protocol (CCEAP) that can be used in didactic environments. In addition, compared to previous works we lower the barrier for understanding network covert channels by eliminating the requirement for students to understand several network protocols in advance.

Keywords: Covert Channels; Steganography; Information Hiding
