Vacancies
PhD student on the subject of topic of security, privacy and trust of distributed systems
Centrum Wiskunde & Informatica (CWI) has a vacancy in the Cryptology research group for a talented PhD student, on the subject of topic of security, privacy and trust of distributed systems.
News
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.
Researchers urge: industry standard SHA-1 should be retracted sooner
An international team of cryptanalysts urges the industry today that SHA-1 internet security standard should be retracted sooner, since the cost of breaking it is significantly lower than previously thought.
Vision on Quantum-Safe Encryption in WIRED and Quanta magazine
Research results of CWI cryptologists Ronald Cramer and Léo Ducas on quantum-safe encryption were discussed in an article on WIRED on 19 September 2015.
