Secure Systems, Postdoc

Peter Pessl is a postdoc in the Secure Systems (SESYS) group at the IAIK. During his doctorate at IAIK, he worked on implementation attacks of cryptographic primitives. He defended his Ph.D. thesis titled "Side-Channel Attacks on Lattice-Based Cryptography and Multi-Processor Systems" in 2018 and graduated under the auspices of the President of Austria. Before joining IAIK, he studied "Information and Computer Engineering", where he received his Master's degree in 2014. His thesis describes an efficient hardware implementation of SHA-3 and ECDSA.

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.
