Welcome to my webpage
We have launched our lab website CESCA
I am a Professor in the Digital Security (DiS) group. I joined the institute for Computing and Information Sciences (iCIS) at the Radboud University in August 2009. Before that I was PostDoc at KU Leuven Belgium where I also got my PhD in 2005. Before that I worked as a cryptographer for Pijnenburg Securealink (later SafeNet B.V.) in The Netherlands. I got my Professional Doctorate in Engineering from TU Eindhoven in 2001.
I have received a VIDI grant from the Dutch government in 2014 to work on new side-channel analysis methods and countermeasures for secure embedded devices.
Since 2018, I am a senior member of IEEE and an Editorial board member of IEEE Transactions on Information Forensics and Security. I am also an AE for ACM TECS.
I was a program co-chair of CHES 2014 in Busan, Korea (the IACR flagship conference on crypto hardware and embedded systems) with Matt Robshaw and of ACMWiSec 2021 with Rene Mayrhofer (virtual).
With Stjepan Picek I was a general co-chair of EUROCRYPT 2020 (the first online IACR conference) and EUROCRYPT 2021 in Zagreb as the first hybrid IACR conference. I was general co-chair of Real World Crypto Symposium for 2021 (virtual) and 2022 (physical in Amsterdam) with Joan Daemen and Peter Schwabe.
My research
My research interests are in applied cryptography and embedded systems security. I am looking into security and privacy of embedded (crypto) devices such as smartcards, mobile phones and IoT devices. Some of the topics I work on include implementations of cryptography, both high performance and low-cost i.e. in constrained environments. I work on implementation attacks i.e. side-channel and faults and I have a preference for curve-based cryptography (both classical and post-quantum i.e. ECC and isogeny-based).
Recently, I've been looking into machine/deep learning for security and privacy and how we can use it for side-channel analysis. Another direction we consider is to perform side-channel analysis on neural nets implementations. I'm also interested in low-cost countermeasures against all kinds of physical attacks, faults and side-channel.
