Abstract

A method of transmitting data in a storage device includes encrypting original data based on a homomorphic encryption algorithm to generate encrypted data, generating a parameter for regeneration of a ciphertext higher than an operation level of the encrypted data by using the encrypted data and a key value, and transmitting the encrypted data and the parameter to an external host device.
