Authenticated Encryption with Associated Data (AEAD) is a class of block cipher modes which encrypt (parts of) the message and authenticate the message simultaneously. Interest in these modes was sparked by the publication of Charanjit Jutla's IACBC and IAPM modes in 2000. As of 2005 this is an active area of cryptographic research. Examples of such modes include OCB mode, CCM mode, EAX mode, CWC mode and GCM mode.
Famous quotes containing the words block, cipher, modes and/or operation:
“Get behind me, Satan! You are a stumbling block to me; for you are setting your mind not on divine things but on human things.”

Jesus to Peter.
“It is not an arbitrary “decree of God,” but in the nature of man, that a veil shuts down on the facts of to-morrow; for the soul will not have us read any other cipher than that of cause and effect. By this veil, which curtains events, it instructs the children of men to live in to-day.”
—Ralph Waldo Emerson (1803–1882)
“Sight and all the other senses are only modes of touch.”
—Samuel Butler (1835–1902)
“It requires a surgical operation to get a joke well into a Scotch understanding. The only idea of wit, or rather that inferior variety of the electric talent which prevails occasionally in the North, and which, under the name of “Wut,” is so infinitely distressing to people of good taste, is laughing immoderately at stated intervals.”
—Sydney Smith (1771–1845)
