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.
