Standard Details
EME2-AES and XCB-AES wide-block encryption with associated data (EAD) modes of the NIST AES block cipher, providing usage guidelines and test vectors, are described. A wide-block encryption algorithm behaves as a single block cipher with a large plaintext input and ciphertext output, but uses a narrow block cipher [in this case Advanced Encryption Standard (AES)] internally. These encryption modes are oriented toward random access storage devices that do not provide authentication, but need to reduce the granularity of a potential attack.

Existing Standards |
Administratively Withdrawn January 2007 The syntax and semantics of the protocol messages that pass between the MMS clientor MMS module and the MM are described. Since this protocol is only used in the context of theMMS, this standard cannot be understood without a thorough understanding of its architecture asdescribed in IEEE Std 1244.1-2000.

This standard specifies cryptographic transform and key archival methods for protection of data in sector-level storage devices.
|
|
This standard specifies cryptographic and data authentication procedures for storage devices that support length-expansion, such as tape drives. Such procedures include the following cryptographic modes of operation for the AES block cipher: CCM, GCM, CBC-HMAC, and XTS-HMAC.
