Vacancies
Tenure-Track and Senior Researcher Positions in Secure Software Systems in Amsterdam
CWI is looking for candidates to initiate and develop new research directions in Secure Software Systems, addressing major challenges in software systems relating to security and privacy. We are looking for researchers with excellent track records in computer science, with a focus on privacy and security in software systems and their scientific foundations. The tenure-track candidates are expected to develop a research program that addresses current societal demands on secure software systems, whereas senior candidates are expected to develop and lead a new group in this area. The candidates are expected to utilise synergies with other CWI research groups, like the cryptology group of prof. Ronald Cramer.

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.”
EU PROMETHEUS project started to develop quantum-safe cryptography
In January 2018 the international PROMETHEUS project has started – a new four-year European H2020 project to prepare ourselves for the threats of the post-quantum era. Dutch research partners in this international project are TNO and CWI.
