Elena Pagnin

Assistant Professor at Information Security

Elena Pagnin is an assistant professor at the Information Security Unit since 2022.

Her research focuses on the design of advanced public key cryptographic primitives and new cryptographic protocols, mainly for authentication or transparency.

She has worked on (train of buzzwords): (multi-key) homomorphic signatures, verifiable computations, messaging protocols, privacy-preserving location proximity testing, storage deduplication, distance-bounding protocols, biometric authentication.
