About Us
DISCRYPT (DIStributed CRYptography and Privacy Technologies) is a research group from Universitat Autònoma de Barcelona dedicated to the study of decentralized systems, privacy-enhancing technologies, and applied cryptography. Its work focuses on developing secure and privacy-preserving solutions in areas such as blockchain, peer-to-peer networks, anonymous communication, and federated learning. We combine theoretical foundations with practical implementations to advance security and privacy in distributed technologies.

(24 Apr 2025) Industry day by DANGER project, within the MEMEnginy
The Industry Day for the DANGER project, held within MEMEnginy on April 24, 2025 at the UAB School of Engineering, will bring together students and industry partners to showcase the project’s goals, methodologies and real-world applications in a hands-on, collaborative setting.
(24 Apr 2025) Divulgation Day in DANGER project: Dices, Entropy and Bitcoin
Learn how to generate fully secure cryptocurrency wallet keys using nothing more than dice—even if they’re biased—in this hands-on workshop, “Dice, Entropy & Bitcoin: Cryptography with Imperfect Dice.” You’ll discover simple yet rigorous methods to ensure maximum entropy and learn how to derive BIP32‐compatible keys used by Bitcoin and other wallets. Join us on April 24, 2025, from 4:30 PM to 6:00 PM in Room Q1/1003 at the UAB School of Engineering for the MEMEnginy event.
