How to share sensitive information safely?
“Data protection is now in the news more often than ever before”, Thijs Veugen, a senior researcher at TNO and part-time seconded in CWI’s Cryptology group says in his recent TNO Time column. “What should a company do if it wants to share information?" "Organizations can use secure multi-party computation to securely link the most sensitive databases together.”
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.
