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.
CWI researcher designs award-winning cryptographic lottery algorithm
Benjamin Wesolowski (CWI) developed a new key ingredient for cryptographic lottery machines and received the Best Young Researcher Paper Award at Eurocrypt 2019. His results can be used for more sustainable blockchain technology.
