In cryptography, New Data Seal (NDS) is a block cipher that was designed at IBM in 1975, based on the Lucifer algorithm that became DES. The cipher uses a block size of 128 bits, and a very large key size of 2048 bits. Like DES it has a 16-round Feistel network structure. The round function uses two fixed 4×4-bit S-boxes, chosen to be non-affine. The key is also treated as an 8×8-bit lookup table, using the first bit of each of the 8 bytes of the half-block as input. The nth bit of the output of
