EU PROMETHEUS project started to develop quantum-safe cryptography
In January 2018 the international PROMETHEUS project has started – a new four-year European H2020 project to prepare ourselves for the threats of the post-quantum era. Dutch research partners in this international project are TNO and CWI.
CRYPTO 2017 Best Paper Award for breaking SHA-1 security standard
A team of researchers from CWI and Google have won the CRYPTO 2017 Best Paper Award for being the first to break the SHA-1 internet security standard in practice. Marc Stevens (CWI) explained this research during a plenary talk at CRYPTO 2017 in Santa Barbara (USA).
CWI and Google research team wins Pwnie Award for Best Cryptographic Attack
Researchers at CWI and Google have won the Pwnie Award for Best Cryptographic Attack at the BlackHat USA security conference. They were awarded the prize for being the first to break the SHA-1 internet security standard in practice.
Marc Stevens’ project awarded funding in ‘Big Data: real time ICT for logistics’ programme
NWO has granted five applications within the ‘Big Data: real time ICT for logistics’ research programme. CWI’s Marc Stevens is the main applicant of one of the five granted research projects: 'Secure scalable policy-enforced distributed data processing'.
