Two new publications and a new pattern

An upcoming publication [1] proposes a new pattern that exploits artificial reconnections. We already added it to the website as PT15 Artificial Reconnections.

Moreover, my (Steffen's) habilitation thesis is now available, its core topic are hiding patterns:

• Steffen Wendzel: Network Information Hiding: Terminology, Taxonomy, Methodology and Countermeasures (PDF), Habilitation Thesis, Department of Mathematics and Computer Science, Unversity of Hagen, submitted in Nov. 2019, colloquiums passed in Nov. 2020.

New paper shows feasibility of covert channels in hash chains

Our new paper (published in MDPI Appl. Sci., open access) uses the Random Value pattern to realize a plausibly deniable covert channels in one-time passwords based on hash chains.

Hands-on tool for Covert Channel Patterns Detection now available!

The tool NeFiAS (Network Forensic & Anomaly Detection System) is an accessible hands-on tool for network covert channel detection. I just made the code of NeFiAS public. I also attached a documentation. Have fun with it!

Free Online Class on Network Information Hiding (and Patterns!)

My (Steffen's) online class on Network Information Hiding is now freely available on Github, including videos on Youtube. You can find it here.
