Game-Theoretic Modeling of Stealthy Intrusion Defense against MDP-Based Attackers
Willie Kouam, Stefan Rass
The rapid expansion of Internet use has increased system exposure to cyber threats, with advanced persistent threats (APTs) being especially challenging due to their stealth, prolo…
Post-Quantum Sanitizable Signatures from McEliece-Based Chameleon Hashing
Shahzad Ahmad, Stefan Rass, Zahra Seyedi
We introduce a novel post-quantum sanitizable signature scheme constructed upon a chameleon hash function derived from the McEliece cryptosystem. In this design, the designated san…
On Unique Neighborhoods in Bipartite and Expander Graphs
Stefan Rass
An undirected graph is said to have \emph{unique neighborhoods} if any two distinct nodes have also distinct sets of neighbors. In this way, the connections of a node to other node…
Statistically Testing Training Data for Unwanted Error Patterns using Rule-Oriented Regression
Stefan Rass, Martin Dallinger
Artificial intelligence models trained from data can only be as good as the underlying data is. Biases in training data propagating through to the output of a machine learning mode…
