Welcome to my webpage

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 a PhD student and PostDoc at the COSIC group, KU Leuven Belgium. Before that I worked as a cryptographer for Pijnenburg Securealink (later SafeNet B.V.) in The Netherlands.

I have received a VIDI grant 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.

My research

My research interests are mostly in the area of applied cryptography and hardware security. In particular, I am interested in security of small embedded devices such as RFID tags, IoT devices etc. Some of the topics I worked on in the past 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 such as (H)ECC. Recently, I've been looking into machine/deep learning for security and privacy and how we can use it for side-channel analysis. On the defending side, I'm interested in low-cost countermeasures against all kinds of physical attacks.

For a complete list of my publications check my DBLP and Google Scholar pages.
