ISO/IEC 18033-3:2010 |
|---|---|
| SCOPE | 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. |

This standard specifies block ciphers. Their purpose is to achieve confidentiality. This standard has been confirmed in 2016 by the WG2 experts so its status seems stable, but will be soon undergo some changes. Two amendments are almost standardised, one is about the inclusion of SM4 (a Chinese block cipher) and the other about the inclusion of Kuznyechik (a Russian block cipher). Kuznyechik is currently not accepted unanimously by the experts in WG2, because some works from Léo Perrin questioned the security of the design of the algorithm. The cryptographic community and the WG2 experts are carefully studying this possible issue before accepting its final standardization. Currently, there is no proof that this algorithm is not secure, although the risk is for now too important for WG2 to move forward. The final decision will be taken this year or the next.
