Embodiment Construction

[0015] figure 1 A secure storage area network system 10 implementing the storage application of the present invention is shown. like figure 1 As shown, the data sources providing the plaintext data to be stored in the storage application 15 (implementing storage media, eg disk 21 and tape 22 ) are located eg in the server device 12 . It will be appreciated that other non-volatile types of storage media may be implemented, such as optical disks, magnetic disks, compacts, flash drives, etc., as well as volatile storage media. The data blocks to be written out to the storage application are encrypted according to the processing provided by the security software program 20 , which is executed on the server device 12 in order to generate the ciphertext stored in the storage application 15 . In one embodiment, server device 12 provides a network interface to operate on server device 12 according to a storage area network communication standard, such as Fiber Channel or iSCSI, over...

Abstract

A system and method implementing advanced cryptographic techniques to protect both the confidentiality and integrity of data sent to and received from a storage system or storage utility. Particularly, the system and method provides for the privacy and integrity of stored data. The integrity protection scheme employed defends against modification of data as well as 'replay' and 'relocation' of data since cryptographic integrity values are not only a function of the plaintext data and a cryptographic key, but also a function of the 'address' of the disk block and a 'whitening' value that defends against 'replay attacks'. The integrity scheme protects the integrity of an entire virtual disk while allowing incremental, random access updates to the blocks on the virtual disk.

Description

technical field [0001] The present invention relates to data storage systems, and more particularly to a novel storage utility in which the confidentiality and integrity of information is protected. Background technique [0002] Enterprise IT infrastructure must be flexible and "responsive" so that the enterprise can quickly adapt to changes in market and business conditions, and as IT infrastructure is increasingly becoming "mission-critical", it must be elastic. Storage applications can provide this kind of flexibility, responsiveness and elasticity, and it can allow enterprises to focus on their core competencies and outsource their storage to specialized companies. Storage applications can be flexible and dynamically respond to an enterprise's storage needs, providing more or less storage as needed, with a variable cost structure based on the amount of storage used. Storage applications can also provide resiliency through disk "mirroring" and backup and recovery service...
