The EAX Mode of Operation [PDF]

, 2004
We propose a block-cipher mode of operation, EAX, for solving the problem of authenticated-encryption with associated-data (AEAD). Given a nonce N, a message M, and a header H, our mode protects the privacy of M and the authenticity of both M and H. Strings N, M, and H are arbitrary bit strings, and the mode uses 2 lceil |M|/nrceil + lceil |H|/nrceil +
