Abstract
A homomorphic encryption operator includes: a level configuration unit configured to set an encryption level by selecting a plurality of prime numbers of different values according to a scale factor condition used for multiplication of a homomorphic encryption operation and an increase/decrease condition for increasing or decreasing consecutively selected prime numbers, and a modular multiplication operator configured to perform lightweight modular multiplication using the selected plurality of prime numbers, wherein the level configuration unit includes: a level constructor configured to select prime number sets whose number have selected Hamming weights, respectively, based on the scale factor condition and the increase/decrease condition, and wherein the level configuration unit is further configured to configure the selected prime number sets with the encryption level using a prime number table.
