DYST (Did You See That?): An Amplified Covert Channel That Points To Previously Seen Data
Steffen Wendzel, Tobias Schmidbauer, Sebastian Zillien +1
Covert channels are stealthy communication channels that enable manifold adversary and legitimate scenarios, ranging from malware communications to the exchange of confidential inf…
Exploration of Differentiability in a Proton Computed Tomography Simulation Framework
Max Aehle, Johan Alme, Gergely Gábor Barnaföldi +47
Objective. Algorithmic differentiation (AD) can be a useful technique to numerically optimize design and algorithmic parameters by, and quantify uncertainties in, computer simulati…
A Revised Taxonomy of Steganography Embedding Patterns
Steffen Wendzel, Luca Caviglione, Wojciech Mazurczyk +8
Steganography embraces several hiding techniques which spawn across multiple domains. However, the related terminology is not unified among the different domains, such as digital m…
Protocol-independent Detection of "Messaging Ordering" Network Covert Channels
Steffen Wendzel
Detection methods are available for several known covert channels. However, a type of covert channel that received little attention within the last decade is the "message ordering"…
Countering Adaptive Network Covert Communication with Dynamic Wardens
Wojciech Mazurczyk, Steffen Wendzel, Mehdi Chourib +1
Network covert channels are hidden communication channels in computer networks. They influence several factors of the cybersecurity economy. For instance, by improving the stealthi…
The New Threats of Information Hiding: the Road Ahead
K. Cabaj, L. Caviglione, W. Mazurczyk +3
Compared to cryptography, steganography is a less discussed domain. However, there is a recent trend of exploiting various information hiding techniques to empower malware, for ins…
