Improved Key Generation For Gentry's Fully Homomorphic Encryption Scheme
Abstract
A key problem with the original implementation of the Gentry Fully Homomorphic Encryption scheme was the slow key generation process. Gentry and Halevi provided a fast technique for $2$-power cyclotomic fields. We present an extension of the Gentry--Halevi key generation technique for arbitrary cyclotomic fields. Our new method is roughly twice as efficient as the previous best methods. Our estimates are backed up with experimental data.
