Faster NTRU-based Bootstrapping in less than 4 ms w/ Zhihao Li

Abstract

Bootstrapping is a critical technique in constructing fully homomorphicencryption (FHE), which serves to refresh the noise in FHE ciphertexts, enabling anarbitrary number of homomorphic operations. This talk will present an efficient bootstrapping algorithm based on NTRU. The improvement consists of two main aspects, including algorithmic innovation and implementation optimization.
