Since its introduction more than a decade ago the homomorphic properties of the NTRU encryption scheme have gone largely ignored. A variant of NTRU proposed by the researchers was recently extended into a full edged multi-key fully homomorphic encryption scheme by Alt-Lopez, Tromer and Vaikuntanathan (ATV). This NTRU based FHE presents a viable alternative to the currently dominant BGV style FHE schemes. While the scheme appears to be more efficient, a full implementation and comparison to BGV style implementations has been missing in the literature.
