Description

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 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 and Google announce first collision for Industry Security Standard SHA-1

CWI and Google announce first collision for Industry Security Standard SHA-1

'Industry deprecation proved to be too slow' Today, Thursday 23 February 2017, researchers at the Dutch research institute CWI and Google jointly announce that they have broken the SHA-1 internet security standard in practice. This industry standard is used for digital signatures and file integrity verification, which secure credit card transactions, electronic documents, GIT open-source software repositories and software distribution.
