Abstract

The invention relates to a storage system and a method for performing and authenticating write-protection thereof. 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 at least one of the start address information and the length information, and 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.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to U.S. Provisional Patent Application No. 61 / 971,673, filed March 28, 2014, and Korean Patent Application No. 10-2014-0117786, filed September 4, 2014 at the Korean Intellectual Property Office, The entire content of said application is incorporated herein by reference. technical field [0003] The inventive concept described herein relates to a storage system, and more specifically, to a storage system and a write protection method thereof. Background technique [0004] A storage system includes a host and storage devices. Hosts and storage devices are connected through various standardized interfaces such as Serial ATA (SATA), Universal Flash Memory (UFS), Small Computer System Interface (SCSI), Serial Attached SCSI (SAS), and Embedded MMC (eMMC). [0005] In conventional storage devices, anyone sets and releases write protection through predetermined commands. The type of write p...
