Abstract
A homomorphic encryption device includes: a recryption parameter generating circuit, a recryption circuit, and an arithmetic circuit. The recryption parameter generating circuit is configured to generate a recryption parameter including a plurality of recryption levels respectively for a plurality of ciphertexts based on an arithmetic scenario including information about an arithmetic schedule between the plurality of ciphertexts. The recryption circuit is configured to generate a plurality of recrypted ciphertexts by recrypting each of the plurality of ciphertexts to a corresponding recryption level based on the recryption parameter. The arithmetic circuit is configured to output an arithmetic result by performing operations by using the plurality of recrypted ciphertexts, according to the arithmetic scenario.
