Cryptology

Investigating how cryptologic methods can contribute to solving security issues, for example through encryption, digital signatures and secure computation.

The 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.
