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.
ERC Advanced Grant for CWI cryptographer Ronald Cramer
CWI cryptographer Ronald Cramer has been awarded an ERC Advanced Grant of 2.5 million euro for his proposal 'Algebraic Methods for Stronger Crypto'. He leads the Cryptology Research group at Centrum Wiskunde & Informatica (CWI) in Amsterdam and is a full professor at the Mathematical Institute of Leiden University. The European Research Council awards these most prestigious personal grants to outstanding, well-established scientists with novel ideas towards high-risk, groundbreaking research that impacts both science and society at large.
CWI and Google announce first collision for Industry Security Standard SHA-1
'Industry deprecation proved to be too slow' Today, Thursday 23 February 2017, researchers at the Dutch research institute CWI and Google jointly announce that they have broken the SHA-1 internet security standard in practice. This industry standard is used for digital signatures and file integrity verification, which secure credit card transactions, electronic documents, GIT open-source software repositories and software distribution.
