Cryptography Research Group

This is the homepage of the cryptography research group in the Institute of Computer Science in the Faculty of Science and Technology at the University of Tartu.

The cryptography group conducts research into cryptography, in particular into the following areas:

  • Cryptographic protocol design, including: e-voting, privacy-preserving data mining, secure computation, zero knowledge
  • Cryptographic protocol analysis, symbolic cryptography
  • Quantum cryptography
  • Theory of cryptography

We form part of the Estonian Center of Excellence in Computer Science, an Academic Centre of Excellence in Research in Computer Science.

The group is responsible for the teaching of cryptography, information security, and various parts of theoretical computer science in the Institute of Computer Science.
