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.
Veni grants for Léo Ducas and Johannes Köster
The Netherlands Organisation for Scientific Research (NWO) has awarded Veni grants to Léo Ducas and Johannes Köster of CWI.
First book on quantum-secure multi-party computation
Ronald Cramer (Centrum Wiskunde & Informatica), Ivan Damgard and Jesper Nielsen (Aarhus University) recently published the first book ever on information-theoretically secure multiparty computation (MPC) – a subfield of cryptography that describes security systems that cannot even be broken by quantum computers or unlimited computing power.
