CAN/CSA-ISO/IEC 18033-3:06

This National Standard of Canada is equivalent to International Standard ISO/IEC 18033-3:2005. 1 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 six different block ciphers are defined. They are categorized in Table 1. 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.
