Private Information Retrieval with Preprocessing Based on the Approximate GCD Problem

Abstract

PIR protocols allow clients to privately recover data on a server. While many protocols exist, none of them are practical due to their high computation requirement. We explain how preprocessing is a necessity to solve this issue, then we present two independent but related results. First, we show how Goldberg’s robust multi-server PIR protocol is compatible… (More)
