Course Description

Overview

Explore a cutting-edge approach to Private Information Retrieval (PIR) in this 20-minute IEEE conference talk. Delve into the SPIRAL family of PIR protocols, which leverages Fully Homomorphic Encryption (FHE) composition to achieve fast, high-rate single-server PIR. Examine efficiency metrics, compare SPIRAL with prior work like Gentry-Halevi, and understand parameter selection for optimal performance. Discover the potential of SPIRALSTREAM in the streaming setting and gain insights into future directions for PIR research and applications.
