本文件定义了用于射频识别（RFID）设备的ISO/IEC 18000空中接口标准的SIMON加密套件。其目的是为RFID设备的安全性提供一个通用的加密套件，供ISO空中接口标准和应用标准委员会参考。加密套件的定义与现有的空中接口一致。 SIMON是一种对称分组密码，其分组长度和密钥长度都是参数化的。在本标准中，支持多种块/键长度选项。 本文件定义了密码的各种使用方法。 标签和询问器可以支持一个、一个子集或所有指定选项，明确说明支持什么。

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.
