Description

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).

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.

— a general description of an anonymous entity authentication mechanism based on signatures using a group public key;

— a variety of mechanisms of this type.

This part of ISO/IEC 20009 describes

— the group membership issuing processes;

— anonymous authentication mechanisms without an online Trusted Third Party (TTP);

— anonymous authentication mechanisms involving an online TTP.

Furthermore, this part of ISO/IEC 20009 also specifies

— the group membership opening process (optional);

— the group signature linking process (optional).
