This document defines the Rabin-Montgomery (RAMON) crypto suite for the ISO/IEC 18000 series of air interfaces standards for radio frequency identification (RFID) devices. Its purpose is to provide a common crypto suite for security for RFID devices that can be referred to by ISO/IEC for air interface standards and application standards.

This document specifies a crypto suite for Rabin-Montgomery (RAMON) for air interface for RFID systems. The crypto suite is defined in alignment with existing air interfaces.

This document 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.
