Institute of Electrical and Electronics Engineers (IEEE) standardization project for encryption of stored data, but more generically refers to the Security in Storage Working Group (SISWG), which includes a family of standards for protection of stored data and for the corresponding cryptographic key management.
The P1619.1 Authenticated Encryption with Length Expansion for Storage Devices uses the following algorithms: The P1619.2 Standard for Wide-Block Encryption for Shared Storage Media has proposed algorithms including: The P1619.3 Standard for Key Management Infrastructure for Cryptographic Protection of Stored Data defines a system for managing encryption data at rest security objects which includes architecture, namespaces, operations, messaging and transport.
For these reasons, the working group selected the narrow-block (128 bits) encryption with no authentication in the standard P1619, assuming that the added efficiency warrants the additional risk.
In the 30 Aug 2006 Archived 11 March 2007 at the Wayback Machine meeting of the SISWG, a straw poll showed that most members would not approve P1619 as it was.
Some members of the group found it non-trivial to abandon LRW, because it had been available for public peer-review for many years (unlike most of the newly suggested variants).
