Verifiable encodings in multigroup fully homomorphic encryption

Ramsès Fernàndez-València, IOV Labs

Abstract

This article presents the application of homomorphic authenticators, replication encodings to be precise, to multigroup fully homomorphic encryption schemes. Following the works of Gennaro and Wichs on homomorphic authenticators in combination with the work of multigroup schemes by Kwak et al. we present a verifiable solution for a fully homomorphic primitive that includes the multikey, multiparty and single user cases. Furthermore, we propose a line of research for the future with constrained-resource scenarios.
