Gareth T. Davies

Overview

I'm a postdoc at the University of Wuppertal, working in Tibor Jager's IT Security and Cryptography group, as part of the REWOCRYPT project. My research focus is cryptographic protocols, with a recent lean towards updatable encryption and topics related to secure storage. I recently served on the program committees of CT-RSA 2022 and SSR 2022 and will serve on the PC for the second cycle of ACM CCS 2022.
