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 18014-2:04 (adoption of ISO/IEC 18014-2:2002, first edition, 2002-12-15). At the time of publication, ISO/IEC 18014-2:2009 is available from ISO and IEC in English only. CSA 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 approved as a National Standard of Canada by the Standards Council of Canada.

Scope

This part of ISO/IEC 18014 presents a general framework for the provision of time-stamping services.

Time-stamping services may generate, renew and verify time-stamp tokens.

Time-stamp tokens are associations between data and points in time, and are created in a way that aims to provide evidence that the data existed at the associated date and time. In addition, the evidence may be used by non-repudiation services.

This part of ISO/IEC 18014 specifies mechanisms that generate independent time-stamps: in order to verify an independent time-stamp token, verifiers do not need access to any other time-stamp tokens. That is, timestamp tokens are not linked, as is the case for the token types defined in ISO/IEC 18014-3.
