Leo Ducas (CWI Cryptology Group) involved in NIST Post-Quantum Cryptography Standardization Finalists
In its process to develop the first cryptographic standard to protect sensitive electronic data against the threat of quantum computers, the US National Institute of Standards and Technology (NIST) announced the finalists. Léo Ducas from CWI's Cryptology group is involved in several finalists of this standardization process.
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.
