Title: Replication Is NOT Needed: A SINGLE Database, Computational PIR
Authors: E. Kushilevitz and R. Ostrovsky
PDFNot Available
Abstract: We establish the following, quite unexpected, result: replication of data for the computational Private Information Retrieval (PIR) problem is not necessary! More specifically, based on the quadratic residuosity assumption, we present a {\em single database}, computationally-private information-retrieval scheme with $O(n^\epsilon)$ communication complexity for any $\epsilon >0$.
