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.
