Cryptology and Data Security Research Group
The Cryptology and Data Security Research Group at the Institute of Computer Science of the University of Bern investigates security and privacy in a digital world.
Our research addresses cryptographic protocols, distributed consistency, consensus, and cloud-computing security, with applications to blockchains, distributed ledger technology, cryptocurrencies, and their economics.
Security and privacy are at stake in the information society, threatened by the enormous developments in networks, cloud, and mobile. Information technology has already revolutionized many aspects today’s life. Finding a balance between the practical convenience of being “always online”, current business practices, the changing demands of society, and the privacy and security concerns of individual people represents one of the great open questions of our time.
Cryptography and data security provide techniques to answer this question.
