Advanced Privacy for Cryptographic Primitives and Protocols

Privacy is a fundamental property required of many cryptographic primitives and protocols. Data privacy has traditionally been considered a pillar for secure designs, and user privacy is an increasingly more sought-after property in a variety of settings.

The study of the notion of privacy in its varying strengths and contexts represents a research area the Cryptography Group focuses on.

Our results have appeared in award-winning papers and range from developing schemes satisfying increasingly stronger notions of data privacy to balancing the need for user privacy with accountability. In certain contexts, such as broadcast encryption and digital signatures, our contributions have pioneered the research on anonymity and incoercibility, a very advanced form of privacy.
