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.

Scope:

This document defines a coding suite based on an exclusive or (XOR) operation for the ISO/IEC 18000 air interfaces standards for radio frequency identification (RFID) systems. In particular, it specifies the use of XOR as a basic way to hide plain data in the identity authentication and secure communication procedures. The coding suite is defined in alignment with existing air interfaces.

This document defines various authentication methods and methods of use for the XOR. A tag and an interrogator may support one, a subset, or all of the specified options, clearly stating what is supported.
