Summary

This part of ISO/ IEC 18033 specifies block ciphers. A block cipher maps blocks of n bits to blocks of n bits,
under the control of a key of k bits. A total of seven different block ciphers are defined. They are
categorized in TH69H69H69H89able 1.
Table 1 — Block ciphers specified
Block length Algorithm name (see #) Key length
64 bits
TDEA (4H79H79H79.2) 128 or 192 bits
MISTY1 (4H89H89H89.3)
CAST-128 (4H99H99H99.4) 128 bits
HIGHT (4H001H001H001.5)
128 bits
AES (5H101H101H101.2)
128, 192 or 256 bits
Camellia (5H201H201H201.3)
SEED (5H301H301H301.4) 128 bits
The algorithms specified in this part of ISO/ IEC 18033 have been assigned object identifiers in accordance
with ISO/ IEC 9834. The list of assigned object identifiers is given in Annex B. Any changes to the
specification of the algorithms resulting in a change of functional behaviour will result in a change of the
object identifier assigned to the algorithm.
