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.


Future mobile payments safer with quantum cryptographic identification

Payment by mobile phone will be common in the near future. Security of the payment system will partly be based on secure identification, and it will be crucial that no secret-key material, like a PIN or a password, is leaked while interacting with the payment terminal. Niek Bouman of Centrum Wiskunde & Informatica (CWI) in Amsterdam has investigated a new identification method based on quantum mechanics.
