Information technology - Security techniques - Encryption algorithms - Part 4: Stream ciphers (Adopted ISO/IEC 18033-4:2011, second edition, 2011-12-15)
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 18033-4-06 (adoption of ISO/IEC 18033-4:2005). At the time of publication, ISO/IEC 18033-4:2011 is available from ISO and IEC in English only. CSA Group will publish the French version when it becomes available from ISO and IEC. This International Standard was reviewed by the 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 TCIT will review these documents for approval and publication. For a listing, refer to the Current Standards Activities page at standardsactivities.csa.ca. 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 a) output functions to combine a keystream with plaintext, b) keystream generators for producing keystream, and c) object identifiers assigned to dedicated keystream generators in accordance with ISO/IEC 9834. NOTE 1 The list of assigned object identifiers is given in Annex A. NOTE 2 Any change to the specification of these algorithms resulting in a change of functional behaviour will result in a change of the object identifier assigned to the algorithms concerned.
