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'.
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.
