DEAL

From CryptoDox, The Online Encyclopedia on Cryptography and Information Security

DEAL (Data Encryption Algorithm with Larger blocks) is a block cipher derived from the Data Encryption Standard (DES). The design was proposed in a report by Lars Knudsen in 1998, and was submitted to the AES contest^[1] by Richard Outerbridge (who notes that Knudsen had presented the design at the SAC conference in 1997).

DEAL is a six- or eight-round Luby-Rackoff cipher that uses DES as its round function, with allowed key lengths of 128, 192, and 256 bits.
