1167 be added at anytime during an EAX stream, and is part of the authentication tag. That is, changes in the meta-data can be detected by changes in the output tag.

1333 . OCB is an encryption protocol that simultaneously provides authentication. It is slightly faster to use than EAX mode
1543 however, unlike EAX it cannot accept \textit{additional authentication data} (meta--data) after plaintext has been processed. This mode also only works with
1547 unique to every session. Next, the the optional additional authentication data is processed, and finally the plaintext (or ciphertext depending on the direction).
1577 \subsubsection{Additional Authentication Data}
1578 After the entire IV has been processed, the additional authentication data can be processed. Unlike the IV, a packet/session does not require additional
1579 authentication data (AAD) for security. The AAD is meant to be used as side--channel data you want to be authenticated with the packet. Note: once
1588 This adds the additional authentication data \textit{adata} of length \textit{adatalen} to the GCM state \textit{gcm}.
1606 To terminate a GCM state and retrieve the message authentication tag call the following function.
2068 It is highly recommended that you \textbf{not} use the MD4 or MD5 hashes for the purposes of digital signatures or authentication codes.
2075 \chapter{Message Authentication Codes}
2077 Thanks to Dobes Vandermeer, the library now includes support for hash based message authentication codes, or HMAC for short. An HMAC
2078 of a message is a keyed authentication code that only the owner of a private symmetric key will be able to verify. The purpose is
2201 algorithm which produces a Message Authentication Code (MAC) using only a block cipher such as AES. Note: OMAC has been standardized as

2499 As of LibTomCrypt v1.15, XCBC-MAC (RFC 3566) has been provided to support TLS encryption suites. Like OMAC, it computes a message authentication code
