Abstract: A storage device and an operating method are provided. The storage device includes a non-volatile memory comprising a first area configured to store a plurality of normal firmware images and a second area configured to store a plurality of trusted firmware images, a firmware table configured to store information about the plurality of normal firmware images and the plurality of trusted firmware images, and a storage controller configured to control the non-volatile memory, perform a self-test for the storage device and write at least one of the plurality of trusted firmware images over a boot image based on a result of the self-test. The firmware table is configured to store a first hash value calculated before encryption of the plurality of trusted firmware images, and a second hash value calculated after encryption of the plurality of trusted firmware images.

Abstract: A storage device includes a non-volatile memory configured to store an encryption key and a data key encrypted with the encryption key, writes data using the data key, and reads the data using the data key; and a storage controller, wherein the storage controller is configured to receive a first security setting command which allows access to the data key, using a first password, generates a first key on the basis of the first password in response to the first security setting command, encrypts the encryption key with the first key to generate a first encrypted encryption key, encrypts the first key with the encryption key to generate an encrypted first key, and stores the first encrypted encryption key and the encrypted first key in the non-volatile memory.
