Cryptographic security at the speed of light
When people who distrust each other want to securely cooperate, they can use cryptographic 'commitment schemes'. Max Fillinger (CWI) designed and analyzed relativistic commitment schemes. He defends his PhD thesis 'Bit-Commitments: Classical, Quantum and Non-Signaling' on 19 March.
Renowned scientists and policy advisors speak at CWI Lectures on Privacy and Security
Our privacy, a fundamental right, is threatened by surveillance and smart algorithms. Can our privacy be salvaged from 'intelligent' machines? During the CWI Lectures 2018 four renowned scientists and policy advisors discuss the state of the art in protecting privacy. Keynote speakers: Marc Rotenberg (USA), Jan Camenisch (Switzerland), Adam Smith (USA) and Ed Felten (USA), former advisor of Barack Obama.
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.”
