In cryptography, Camellia is a block cipher that has been evaluated favorably
by several organisations, including the European Union's NESSIE project (a
selected algorithm), and the Japanese CRYPTREC project (a recommended
algorithm). The cipher was developed jointly by Mitsubishi and NTT in 2000,
and has similar design elements to earlier block ciphers (MISTY1 and E2) from
these companies.
Camellia has a block size of 128 bits, and can use 128-bit, 192-bit or 256-bit
keys - the same interface as the Advanced Encryption Standard. It is a
Feistel cipher with either 18 rounds (if the key is 128 bits) or 24 rounds (if
the key is 192 or 256 bits). Every six rounds, a logical transformation layer
is applied: the so-called "FL-function" or its inverse. Camellia uses four 8 x
8-bit S-boxes with input and output affine transformations and logical
operations. The cipher also uses input and output key whitening. The diffusion
layer uses a linear transformation based on an MDS matrix with a branch number
of 5.
On June, 18 2008, support for the adopted Camellia cipher was added to the
final release of Mozilla Firefox 3.[citation needed]
