Research

Core Research Areas:

Large-scale Cryptography: Constructing cryptosystems (e.g. public-key encryption and digital signatures) with scalable security

Post-quantum Secure Communication: Designing new protocols to secure our digital communication against powerful quantum attackers, including (password-based) key exchange protocols

Foundations for Privacy: Improving (non-interactive) zero-knowledge proof systems

Fine-grained Cryptography: Constructing advanced cryptography from low-level, fine-grained complexity problems

Collaboration partners:

The group is well connected with international, world-class cryptography groups at UC San Diego (USA), UC Berkeley (USA), ETH Zürich (Switzerland), NTNU (Norway), NTT Tokyo (Japan), etc.
