OnionPIRv2: Efficient Single-Server PIR
Abstract
This paper presents OnionPIRv2, an efficient implementation of OnionPIR incorporating standard orthogonal techniques and engineering improvements. OnionPIR is a single-server PIR scheme that improves response size and computation cost by utilizing recent advances in somewhat homomorphic encryption (SHE) and carefully composing two lattice-based SHE schemes to control the noise growth of SHE. OnionPIRv2 achieves
