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.”

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.
