Summary: | A storage system includes a host device and a storage device. The host device generates a file, and generates a unique file identifier (UFID) for each file, wherein the UFID is based on an identifier of the generated file and at least one logical address corresponding to the generated file. The storage device generates a key for encrypting or decrypting write data corresponding to the generated file based on the UFID and a random number, and encrypts the write data by using the key. |
