Obfuscating Many-to-one Functional Re-encryption, and its Connection to Fully-Homomorphic Encryption

Abstract

Following up on its first construction by Gentry (STOC 2009), fully-homomorphic encryption (FHE) has generated a multitude of different works, seeking both for new theoretical approaches as well as for more efficient instantiations. All existing FHE schemes, however, are tightly connected to specific assumptions, and no generic constructions are known. In… (More)
