Leader of the group Cryptology: Ronald Cramer.

Our research group is concerned with digital security, an area of increasingly pressing concern for industry, government and society at large. We investigate how cryptologic methods can contribute to solving security issues, for example through encryption, digital signatures and secure computation. Furthermore, we seek to establish the reliability of current cryptologic methods, how they can be improved, and what better alternatives there might be.
Quantum safety, meaning security in a possible future age of quantum computing, is a particular focus of our research.

Cécile Pierrot wins Cercle K2 Cybersecurity Trophy 2017

Cécile Pierrot from the Cryptology research group at CWI won the first Cybersecurity Trophy granted by Cercle K2. This French think tank awards prizes in 22 topics every two years. It aims at stimulating interdisciplinarity and promoting young researchers. The Cybersecurity Trophy 2017 rewarded Pierrot’s PhD thesis, which she defended at UPMC in Paris on 25 November 2016. The jury praised her for both theoretical and practical impacts of her results.

CWI Lectures on privacy & security 2018

Turing zaal

Our privacy is a fundamental right. Unfortunately, it is severely threatened by ubiquitous surveillance by governments and Internet moguls alike. Even worse, intense analysis of all this personal data by smart algorithms promises to make us completely transparent and predictable, and hence even more vulnerable. Will we be able to salvage our privacy from the claws of the 'intelligent' machines?

In this years' CWI Lectures four renowned scientists and policy advisors will discuss the state of the art in protecting privacy as well as the policy challenges to be faced when implementing these.

The CWI Lectures 2018 will be held on Thursday 15 November and the symposium is aimed towards a general academic audience. The theme will be Privacy and Security and the program committee for this afternoon consists of Prof. Ronald Cramer (CWI, Leiden University) and Dr. Jaap-Henk Hoepman (Radboud University, University of Groningen, Tilburg University).

The event will be held at the Amsterdam Science Park Congress Center and participation is free after registration.
***Please note that a possible cancellation of your participation needs to be done by email ( on Wednesday 7 November at the latest. When you don’t cancel your participation and you do not show up at the event, we are unfortunately obliged to charge you 100 euro no-show fee (invoice will be sent to you).***

Confirmed speakers:

-- Prof. Marc Rotenberg

Marc Rotenberg is President of the Electronic Privacy Information Center (EPIC) in Washington, D.C. He teaches privacy and open government at Georgetown Law and frequently testifies before the US Congress on emerging privacy and civil liberties issues. He has served on several national and international advisory panels. In 2015, he urged the establishment of Algorithmic Transparency as fundamental right. And in 2018, EPIC launched a campaign to make the development of the US AI policy more inclusive of public concerns.


-- Dr. Jan Camenisch

Jan is the Head of Cryptography Research at Prior to that Jan was a Principle Researcher at IBM Research - Zurich. Jan is a leading scientist in the area of privacy and cryptography, has published over 130 widely cited papers, and has received a number of awards for his work, including the 2010 ACM SIGSAC outstanding innovation award and the 2013 IEEE computer society technical achievement award. Jan is also a co-inventor of Identity Mixer, a unique cryptographic protocol suite for privacy-preserving authentication and transfer of certified attributes. He is a Fellow of IEEE and IACR.


-- Prof. Adam Smith

Adam Smith is a professor of computer science at Boston University. He obtained his Ph.D. from MIT in 2004, and was a faculty member at Penn State from 2007 to 2017. His research interests lie in data privacy and cryptography, and their connections to machine learning, statistics, information theory, and quantum computing. He received a Presidential Early Career Award for Scientists and Engineers (PECASE) in 2009; a Theory of Cryptography Test of Time award in 2016; and the 2017 Gödel Prize.


-- Prof. Ed Felten

Edward W. Felten is the Robert E. Kahn Professor of Computer Science and Public Affairs at Princeton University, and the
founding Director of Princeton's Center for Information Technology Policy. In 2015-2017 he served in the
White House as Deputy U.S. Chief Technology Officer. In 2011-12 he served as the first Chief Technologist at the U.S. Federal Trade Commission. His research interests include computer security and privacy, and technology law and policy. He has published more than 150 papers in the research literature, and three books. He is a member of the National Academy of Engineering and the American Academy of Arts and Sciences, and is a Fellow of the ACM.
