Zusammenfassung:A storage device includes a non-volatile memory, and a memory controller, wherein the memory controller encrypts plaintext to generate a homomorphic ciphertext with a first level among homomorphic ciphertexts with different levels, stores the homomorphic ciphertext with the first level in the non-volatile memory, and provides the homomorphic ciphertext with the first level in response to a request received from a host. The homomorphic ciphertext with the first level has a smallest length among the homomorphic ciphertexts with different levels.
