My research focuses on implementation security, i.e., side-channel and fault attacks as well as protections, of cryptographic primitives. I am particularly interested in lattice-based cryptography and analyze ways of attacking characteristic implementation techniques. I enjoy combining established attack paths, such as power analyis, with algebraic techniques exploiting mathematical properties of the attacked scheme.
I teach an undergraduate course offering an introduction to information security and a graduate course that focuses on side-channel attacks and protections of cryptographic implementations.
