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 SCC Mirror Committee (SMC) 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).

For brevity, this Standard will be referred to as "CAN/CSA-ISO/IEC 18033-1" throughout.

This Standard supersedes CAN/CSA-ISO/IEC 18033-1:06 (adopted ISO/IEC 18033-1:2005). At the time of publication, ISO/IEC 18033-1:2015 is available from ISO and IEC in English only. CSA Group will publish the French version when it becomes available from ISO and IEC.

Scope

The nature of encryption is introduced, and certain general aspects of its use and properties are described. The criteria used to select the algorithms specified in subsequent parts of this International Standard are defined in Annexes A and B.
