Cryptography is one of the main tools for achieving a secure and private digital world. The main objective of our group is to apply cryptography to practice. Topics we work on include privacy-preserving signatures and authentication methods. We also tackle practical problems related to using cryptography on constrained devices like smart cards or cryptographic tokens (e.g., FIDO).
