Leader of the group Cryptology: Ronald Cramer.

Our research group is concerned with digital security, an area of increasingly pressing concern for industry, government and society at large. We investigate how cryptologic methods can contribute to solving security issues, for example through encryption, digital signatures and secure computation. Furthermore, we seek to establish the reliability of current cryptologic methods, how they can be improved, and what better alternatives there might be.
Quantum safety, meaning security in a possible future age of quantum computing, is a particular focus of our research.

Cécile Pierrot wins Cercle K2 Cybersecurity Trophy 2017

Cécile Pierrot from the Cryptology research group at CWI won the first Cybersecurity Trophy granted by Cercle K2. This French think tank awards prizes in 22 topics every two years. It aims at stimulating interdisciplinarity and promoting young researchers. The Cybersecurity Trophy 2017 rewarded Pierrot’s PhD thesis, which she defended at UPMC in Paris on 25 November 2016. The jury praised her for both theoretical and practical impacts of her results.

QCrypt 2020: on-line Conference

  • 2020-08-10T00:00:00+02:00
  • 2020-08-14T23:59:59+02:00
August 10 Monday

Start: 2020-08-10 00:00:00+02:00 End: 2020-08-14 23:59:59+02:00

The annual QCrypt conference is the main international event that is dedicated to the latest developments in the field of quantum cryptography. Researchers from all over the world present their recent scientific discoveries in the field and companies display their latest relevant technology. The topic of the conference covers all aspects of cryptographic security in the presence of quantum devices, including - but not limited to - quantum key distribution, quantum randomness generation, and the impact of quantum computers on classical cryptography. The 10th anniversary edition of the conference, QCrypt 2020  will take place as an online event  and is jointly organized by CWI, UvA and QuSoft.

The conference hosts researchers and scientists from the leading international academic research groups and engineers and industry representatives from international companies; all of which are interested in quantum cryptography as a practical technology and in the security of cryptographic schemes under quantum attacks.

All information (speakers, registration etc) can be found on our website.
