Full Description

Scope

This standard specifies an architecture for encryption of data in random access storage devices, oriented toward applications that benefit from wide encryption-block sizes of 512 bytes and above.

Purpose

This standard specifies an architecture for media security and enabling components. Wide encryption blocks are well suited to environments where the attacker has repeated access to cryptographic communication or ciphertext, or is able to perform traffic analysis of data access patterns. The standard is oriented toward fixed-size encryption blocks without data expansion, but anticipates an optional data expansion mode to resist attacks involving data tampering.

Abstract

Revision Standard - Superseded. 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.
