About me

Since March 2015, I am full professor symmetric cryptography at Radboud University Nijmegen in the Digital Security (DiS) Group and since September 2018 this has become my full-time job. Currently I'm head of the DiS group. Until that date, I worked near Brussels, Belgium as a security architect and cryptographer for STMicroelectronics (2003-2018), previously Proton World (1998-2003), previously Banksys (1996-1998), all that time in the security engineering group led by Yves Moulart. Before that I worked shortly at Bacob Bank (1996) in Brussels as a security architect and I spent one year in IT support at J&J (1995-1996) on the Janssen site in Beerse, Belgium. I did a PhD on the design of symmetric cryptography at COSIC in Leuven from 1988 until 1995.

Grants

Early 2018 I was awarded an ERC advanced grant for my research proposal ESCADA on the foundations of security in symmetric crypto. This has started in October 2018 and I have in the meanwhile hired 6 PhD students and a postdoc. With Bart Mennink I have received mid 2018 an NWO TOP grant for our research proposal related to the design of symmetric crypto optimally exploiting available multipliers. This project has started in August 2019 and we have hired two PhD students and a postdoc on it. Additionally I received some funding from industry for a project on lightweight cryptography and one on low-latency crypto, leading to two more PhD students and one part-time postdoc.

Teaching

I teach and coordinate two bachelor computer security courses here at Radboud University: Computer Security (6ec) and Introduction to Cryptography (6ec). The former I teach together with Simona Samardjiska and Katharina Kohls and the latter with Bart Mennink. I teach one master course in the Radboud cybersecurity master specialization: Cryptology (6ec), together with Simona Samardjiska who is course coordinator. I accompany internships, bachelor and master theses in my own specialization but also in other domains of cryptography and information security.
