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).

This Standard supersedes CSA ISO/IEC 13888-1:10 (adopted ISO/IEC 13888- 1:2009). At the time of publication, ISO/IEC 13888-1:2020 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 Standard has been formally approved, without modification, by the Technical Committee and has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.

Scope:

This document serves as a general model for subsequent parts specifying non-repudiation mechanisms using cryptographic techniques.

The ISO/IEC 13888 series provides non-repudiation mechanisms for the following phases of nonrepudiation:

• evidence generation;
• evidence transfer, storage and retrieval; and
• evidence verification.

Dispute arbitration is outside the scope of the ISO/IEC 13888 series.
