Serge Fehr appointed as Professor Quantum Information Theory
Serge Fehr (CWI, UL) has been appointed as Professor Quantum Information Theory at the Leiden Mathematical Institute (MI) since 1 June 2018. His research is focused on quantum cryptology.
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).
