EME2-AES wide-block encryption with associated data (EAD) mode of the NIST AES block cipher, providing usage guidelines and test vectors, is 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. This encryption mode is oriented toward random access storage devices that do not provide authentication, but need to reduce the granularity of a potential attack.
