Abstract

We prove the multiple messages semantically security of the somewhat homomorphic private-key scheme presented by van Dijk et al. And convert it into a public-key scheme by using Ron Rothblum´s transformation. The initial noise in the scheme is more smaller than that in Coron´s. And can also convert it into a FHE in the ways described by van Dijk.
