scope:

This international standard 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 may be referenced by ISO committees for air interface standards and application standards. This international standard 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 international standard defines various authentication methods and methods of use for the cipher. A tag and an interrogator may support one, a subset, or all of the specified options, clearly stating what is supported.
