Abstract
A device for supporting a homomorphic encryption operation includes a ciphertext conversion circuit configured to convert first ciphertexts corresponding to a first operation size to second ciphertexts corresponding to a second operation size, different from the first operation size, to convert the operated ciphertext having the second operation size to a third ciphertexts corresponding to the first operation size, and to perform a homomorphic encryption operation on the second ciphertexts.
