Webscheme is a bootstrapping algorithm, which is based on the homomorphic accumulator technique [8,32]. To build the bootstrapping algorithm, we construct an NTRU-analog of the GSW encryption scheme by Gentry, Sahai, and Waters [38]. The GSW encryption scheme underlies many previous accumulator-based bootstrapping schemes [8,32,26]. WebGSW Homomorphic Encryption. In GSW homomorphic encryption scheme proposed here. The integers are over Z q where q is a modulus parameter of the scheme. It is not …
