This document defines the crypto suite for SIMON for the ISO/IEC 18000 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 by ISO committees for air interface standards and application standards. The crypto suite is defined in alignment with existing air interfaces.SIMON is a symmetric block cipher that is parameterized in both its block length and key length. In this standard, a variety of block/key length options are supported.This document defines various 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.
