BS ISO/IEC 18033-3:2010+A1:2021
This standard BS ISO/IEC 18033-3:2010+A1:2021 Information technology. Security techniques. Encryption algorithms is classified in these ICS categories:
- 35.030 IT Security
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 eight different block ciphers are defined. They are categorized in Table 1.
Table 1 Block ciphers specified
Block length | Algorithm name (see #) | Key length |
---|---|---|
64 bits | TDEA (4.2) | 128 or 192 bits |
MISTY (4.3) | 128 bits | |
CAST-128 (4.4) | ||
HIGHT (4.5) | ||
128 bits | AES (5.2) | 128, 192 or 256 bits |
Camellia (5.3) | ||
SEED (5.4) | 128 bits | |
SM4 (5.5) |
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.
