Secure Systems, PhD Candidate

Robert Primas is a PhD student, supervised by Stefan Mangard, in the Secure Systems (SESYS) group at the Institute of Applied Information Processing and Communications (IAIK) in Graz, Austria. His current research is focused on implementation security and symmetric/post-quantum cryptography. He received his MSc in Computer Science at Graz University of Technology with focus on IT Security.

My research interests include practical aspects of information security such as constructing and attacking cryptographic implementations as well as more theoretic aspects such as designing cryptographic schemes that feature robustness against physical attacks in addition to cryptanalytic security. I co-designed ISAP, a lightweight authenticated encryption scheme that is currently competing in the final round of the NIST standardization process of lightweight cryptography and gives out-of-the-box strong guarantees against various kinds of physical attacks like fault injection and power analysis.


I currently teach a graduate course that focuses on implementing, as well as attacking cryptographic implementations. The hardware part of this course covers power analysis (DPA/SPA), fault attacks (DFA/SIFA), and corresponding countermeasure techniques. Students receive real hardware for conducting all these experiments.

Looking for a bachelor’s thesis, master’s thesis, or project in symmetric/post-quantum cryptography, and/or implementation security? Let us know, we’re always happy to discuss open topics!
