Discretization Error Reduction for Torus Fully Homomorphic Encryption

ePrint Report: Discretization Error Reduction for Torus Fully Homomorphic Encryption

Kang Hoon Lee, Ji Won Yoon

In recent history of fully homomorphic encryption, bootstrapping has been actively studied throughout many HE schemes. As bootstrapping is an essential process to transform somewhat homomorphic encryption schemes into fully homomorphic, enhancing its performance is one of the key factors of improving the utility of homomorphic encryption.


In this paper, we propose an extended bootstrapping for TFHE, which we name it by EBS. One …
