Abstract: In one embodiment, the method includes receiving, at a storage device, a request. The request includes a request message authentication code and write protect information. The write protect information includes at least one of start address information and length information. The start address information indicates a logical block address at which a memory area in a non-volatile memory of the storage device starts, and the length information indicates a length of the memory area. The method also includes generating, at the storage device, a message authentication code based on (1) at least one of the start address information and the length information, and (2) a key stored at the storage device; authenticating, at the storage device, the request based on the generated message authentication code and the request message authentication code; and processing, at the storage device, the request based on a result of the authenticating.
