    CSA Preface


    Standards development within the Information Technology sector is harmonized with international standards development. Through the CSA Technical Committee on Information Technology (TCIT), Canadians serve as the Canadian Advisory Committee (CAC) on ISO/IEC Joint Technical Committee 1 on Information Technology (ISO/IEC JTC1) for the Standards Council of Canada (SCC), the ISO member body for Canada and sponsor of the Canadian National Committee of the IEC. Also, as a member of the International Telecommunication Union (ITU), Canada participates in the International Telegraph and Telephone Consultative Committee (ITU-T).


    This Standard supersedes CAN/CSA-ISO/IEC 18033-3-06 (adoption of ISO/IEC 18033-3:2005, first edition, 2005-07-01). At the time of publication, ISO/IEC 18033-3:2010 is available from ISO and IEC in English only. CSA will publish the French version when it becomes available from ISO and IEC.


    This International Standard was reviewed by the CSA TCIT under the jurisdiction of the Strategic Steering Committee on Information Technology and deemed acceptable for use in Canada. From time to time, ISO/IEC may publish addenda, corrigenda, etc. The CSA TCIT will review these documents for approval and publication. For a listing, refer to the CSA Information Products catalogue or CSA Info Update or contact a CSA Sales representative. This Standard has been formally approved, without modification, by the Technical Committee and has been approved as a National Standard of Canada by the Standards Council of Canada.


    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 kits. A total of seven 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 behavior will result in a change of the object identified assigned to the algorithm.
