We construct a multikey fully-homomorphic encryption scheme (multikey FHE) with one-round threshold decryption in the plain model, i.e. without a trusted setup, assuming the intractability of standard problems over lattices. Prior to our work, such a scheme was only known to exist assuming sub-exponentially hard indistinguishability obfuscation.
