Interview with Dijkstra Fellow David Chaum
David Chaum (1955) was awarded the Dijkstra Fellowship for his groundbreaking work in privacy and cryptology and the development of digital currency, which laid the technological basis for blockchain and bitcoin. This interview appeared in CWI’s staff magazine in April 2020.
Levchin prize for Marc Stevens’ groundbreaking work on hash functions
For their groundbreaking work on the security of collision resistant hash functions researchers Marc Stevens (CWI) and Xiaoyun Wang (Tsinghua University) were awarded one of the two 2020 Levchin Prizes for real-world cryptography.
David Chaum and Guido van Rossum awarded Dijkstra Fellowship
Centrum Wiskunde & Informatica (CWI) will grant the honorary title ‘Dijkstra Fellow’ for the first time in its history. This edition the Dijkstra Fellowship will be awarded to David Chaum and Guido van Rossum.
IBM to deploy quantum-proof cryptography co-developed with CWI and RU
Together with CWI, RU and other international partners, IBM Research has developed quantum-safe algorithms for securing data. IBM has now implemented these algorithms in the world’s first quantum computing safe tape drive.

QCrypt 2020: on-line Conference
Start: 2020-08-10 00:00:00+02:00 End: 2020-08-14 23:59:59+02:00
The annual QCrypt conference is the main international event that is dedicated to the latest developments in the field of quantum cryptography. Researchers from all over the world present their recent scientific discoveries in the field and companies display their latest relevant technology. The topic of the conference covers all aspects of cryptographic security in the presence of quantum devices, including - but not limited to - quantum key distribution, quantum randomness generation, and the impact of quantum computers on classical cryptography. The 10th anniversary edition of the conference, QCrypt 2020 will take place as an online event and is jointly organized by CWI, UvA and QuSoft.
The conference hosts researchers and scientists from the leading international academic research groups and engineers and industry representatives from international companies; all of which are interested in quantum cryptography as a practical technology and in the security of cryptographic schemes under quantum attacks.
All information (speakers, registration etc) can be found on our website.
