Abstract

See full text

A homomorphic encryption system includes a homomorphic encryption device encrypting original data into a first ciphertext using a homomorphic encryption algorithm, and a homomorphic encryption operation device receiving the first ciphertext from the homomorphic encryption device and performing an approximate arithmetic operation of a transcendental function with respect to the first ciphertext and a second ciphertext by performing a homomorphic multiplication operation in a binary tree structure.
