Abstract
An apparatus including a receiver and a processor configured to generate a modulus switch ciphertext by performing modulus switching with respect to data received by the receiver, the modulus switching including mapping a component of an input ciphertext generated from the received data to an odd number, generate a blind rotated ciphertext by performing a blind rotation operation based on the modulus switched ciphertext, and generate encrypted data, as a homomorphic encryption operation result, by performing key switching based on the blind rotated ciphertext.
