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.
Cryptology researcher Marc Stevens awarded with Google research prize
CWI researcher Marc Stevens of the Cryptology research group has been awarded the Google Security Privacy and Anti-abuse applied award.
New attacks on location-based quantum cryptography
For secure communication of classified information, researchers want to deploy the sender’s location, so a receiver can be sure that a message is, for instance, really coming from the White House. Classic location-based methods are shown to be unsafe but location-based quantum cryptography seemed to have a chance.
Three articles from the Netherlands published in ERCIM News 106 on Cybersecurity
In July 2016, ERCIM News 106 was published: ercim-news.ercim.eu/en106. This issue featured a special theme on Cybersecurity, in which three articles from the Netherlands were published and one from Belgium. Another article from the Netherlands, on the 100th birthday of former CWI (MC) director and informatics pioneer Aad van Wijngaarden, was published in the Research & Society section.
