Method for secure data storage in a dynamic mobile environment

Disclosed is a method for secure data storage in a dynamic mobile environment. Benefits include improved functionality and improved performance.

Background

              Security is an important issue for storing data transferred over inherently insecure networks. Remote block-level storage is expected to become as popular as network-attached storage, in laptops, other mobile devices, and thin clients. On-the-fly backups and access to remote storage from mobile workstations may become common as mobile devices move between base stations.

      Conventional implementations of secure Internet data storage use network interface cards (NICs) or host bus adapters (HBAs) that divert processing from the central processing unit (CPU).

      Several standards/protocols have been adopted for data transfer and storage, including the following:

•     “Internet Small Computer Systems Interface (iSCSI)”, Internet Engineering Task Force Network Working Group, RFC3720, April 2004

•     “The TLS Protocol”, Network Working Group Internet Engineering Task Force, RFC 2246, January 1999

•     “Transport Layer Security (TLS) Extensions”, Internet Engineering Task Force Network Working Group, RFC3546, June 2003

•     “Security Architecture for the Internet Protocol”, Internet Engineering Task Force Network Working Group, RFC2401, November 1998

•     “Transmission Control Protocol (TCP)”, Network Working Group Internet Engineering Task Force, RFC0793 (STD0007), November 1981

•     “Internet Key Exchange (IKE)”, Network Working Group Internet Engineering Task Force, RFC2409, November 1998

•     “Internet Protocol (IP)”, Internet Engineering Task Force Network Working Group, RFC0791 (STD0005), September 1981

•     “Common Open Policy Service (COPS)”, Internet Engineering Task Force Network Working Group, RFC2748, version 1.4.0, May 2002

•     "IEEE Standard for Carrier Sense Multiple Access with Collision Detection (CSMA/CD) Access Method and Physical Layer Specifications", IEEE Local and Metropolitan Area Networks standard 802.3, Nov. 7, 2000, which includes several formats including Ethernet, Gigabit Ethernet, and fibre optic inter-repeater link

•     “Security Architecture for the Internet Protocol”, Internet Engineering Task Force IP Security Protocol (ipsec) Working Group, RFC2401, November 1998

•     “SCSI-2 Common Access Method and SCSI Interface Module (

)”, American National Standards Institute (ANSITM) INternational Committee for Information Technology Standards (INCITSSM), 232‑1996 [R2001], 2001

•     “SCSI Fibre Channel Protocol – 2 (FCP-2)”, ANSI INCITS, 350-2003, 2003
