Researchers hail demise of online security algorithm
An international team of mathematicians has hailed the end of a variant of a code that is widely used to protect online transactions. The five researchers are from EPFL, CWI and the universities of Surrey and Passau.
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.
