Abstract
A storage device includes a memory that includes a firmware image area, and a memory controller that receives a first firmware image that includes a firmware signature, firmware data, a first certificate that includes a first certificate public key, and a second certificate that includes a second certificate public key. The memory controller verifies the first certificate using the second certificate public key, compares a hash value of the firmware data with the firmware fingerprint when the first certificate is verified, verifies the firmware signature using the first certificate public key when the hash value of the firmware data matches the firmware fingerprint, and stores the first firmware image in a firmware image area when the firmware signature is verified.
