Preface Standards development within the Information Technology sector is harmonized with internationalstandards 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 29167-14\" throughout. At the time of publication, ISO/IEC 29167-14:2015 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 This part of ISO/IEC 29167 defines the cryptographic suite for AES using OFB mode (AES OFB) for the ISO/IEC 18000-63 air interface standard for radio frequency identification (RFID) devices. Its purpose is to provide a common cryptographic suite for security for RFID devices that can be referenced by ISO committees for air interface standards and application standards. This part of ISO/IEC 29167 specifies a cryptographic suite for AES OFB for air interface for RFID systems. The cryptographic suite is defined in alignment with existing air interfaces. This part of ISO/IEC 29167 defines various authentication methods and methods of use for the cipher. A tag and an interrogator can support one, a subset, or all of the specified options, clearly stating what is supported.
