Aged 17, I started writing books (sold 65,000 printed+electronic copies so far and counted 60,000+ free downloads of my older editions). A list of my 130+ publications can be found here. My publications appeared in high-quality journals/conference such as
- ACM Computing Surveys (CSUR),
- Communications of the ACM (CACM),
- Elsevier Future Generation Computer Systems (FGCS),
- IEEE ACCESS,
- IEEE Transactions on Industrial Informatics (TII),
- IEEE Security & Privacy,
- IEEE Local Computer Networks (LCN),
- IFIP Information Security and Privacy Protection Conf. (SEC),
- Springer Scientometrics,
- Wiley Security and Communication Networks (SCN),
- Springer Annals of Telecommunications and
- Journal of Universal Computer Science (J.UCS).
My research focuses on network information hiding (network covert channels and network steganography), science of security (SoC), IoT/smart buildings/homes, security of embedded communication protocols, and information security terminology/taxonomy.
Some of my key publications are on the fundamentals (SoC) of network information hiding: taxonomy/patterns/fundamentals [1,2], creativity evaluation of research paper submissions  and scientific methodology of information hiding . Some of my other key contributions are focusing on traffic normalization and active wardens [5, 6] and covert channel optimization [7,8].
I am a member of several steering committees, initiatives, program and organizing committees (cf. details). I am (or was) lecturing and supervising at Augsburg University of Applied Sciences, Bonn University and Hagen University. A list of my projects, both funded and spare-time software projects, is also available.
In addition to information security, I am interested in university history, campus novels, and retro computing – in particular: operating system history and historic network protocols. I own a small collection of rather historic books on these retro computing topics. Since about five years, I am also a mid-distance runner (5km to half-marathon).

Recent News (Selection):
- We organize a new special issue for MDPI Computers on Information Hiding, Steganography and Covert Channels, see https://www.mdpi.com/journal/computers/special_issues/InformationHiding_NetworkSteganography_CovertChannels. Also check our other active SIs for Elsevier FGCS and J.UCS.
- I submitted my habilitation thesis one week ago - yey!
The early-access version (open access) of our paper on MQTT covert channels is now available:
- Aleksandar Velinov, Aleksandra Mileva, Steffen Wendzel, Wojciech Mazurczyk: Covert Channels in MQTT-based Internet of Things, IEEE ACCESS, accepted.
I am proud to say that for the second time, I got a paper accepted in a non-computer science journal, namely Scientometrics (website of the publisher). Yes, our paper has to do with cyber security, somehow, but it is an analysis of citations.
- Steffen Wendzel, Cédric Lévy-Bencheton, Luca Caviglione: Not all Areas are Equal: Analysis of Citations in Information Security Research, Scientometrics, Springer, in press.
