FHE:IDEAs (Interesting Directions and Emerging Applications)

Affiliated Event with Eurocrypt 2024

May 25, 2024

Zürich, Switzerland

Abstract

Fully homomorphic encryption (FHE) is a cryptographic primitive with immense theoretical and practical interest. In the past 15 years, we have gone from the first theoretical constructions of FHE to constructions with implementation libraries that can be run on a laptop. Due to the large number of practical applications, FHE has become an emerging technology of interest in industry. The purpose of this workshop is to give attendees a broad overview of the current state of the art in FHE and discuss future research directions motivated by both theoretical and practical interests.
