DEAL
In cryptography, DEAL is a symmetric block cipher derived from the Data Encryption Standard. The design was proposed in a report by Lars Knudsen in 1998, and was submitted to the AES contest by Richard Outerbridge.
DEAL is a Feistel network which uses DES as the round function. It has a 128-bit block size and a variable key size of either 128, 192, or 256 bits. For key sizes of 128 and 192 bits, the cipher uses 6 rounds, increasing to 8 for the 256-bits size. The scheme has a comparable performance to Triple DES, and was relatively slow compared to many other AES candidates.
