Hi Folks,
NIST has now released a draft of SP 800-38E covering the XTS-AES mode as standardized by IEEE Std 1619-2007. I encourage group members to submit public comments (before Sept 17, 2009). Here is the information off of NIST's website (see http://csrc.nist.gov/publications/PubsDrafts.html):
SP 800-38 E
DRAFT Recommendation for Block Cipher Modes of Operation: The XTS-AES Mode for Confidentiality on Block-Oriented Storage Devices
NIST announces that the Draft NIST Special Publication 800-38E, Recommendation for Block Cipher Modes of Operation: The XTS-AES Mode for Confidentiality on Block-Oriented Storage Devices, is available for public comment. This document approves the XTS-AES mode of the AES algorithm by reference to IEEE Std 1619-2007, subject to one additional requirement, as an option for protecting the confidentiality of data on block-oriented storage devices. This mode does not provide authentication, in order to avoid expansion of the data; however, it does provide some protection against malicious manipulation of the encrypted data.

The XTS-AES mode was submitted to NIST by the IEEE P1619 Task Group. On June 5, 2008, NIST initiated a 90-day period of public comment on the proposal to approve XTS-AES by reference to IEEE Std 1619-2007; during the comment period, IEEE made available free-of-charge the specification of the mode in that standard, and other relevant excerpts. NIST decided to proceed with the proposal after considering the public comments that NIST received, and follow-up comments from the IEEE P1619 Task Group, both available at the modes public comment page.
Comments on the text of the Draft NIST SP 800-38E may be submitted to EncryptionModes@xxxxxxxx until September 17, 2009.
