This document specifies the crypto suite for AES-128 for the ISO/IEC 18000 air interface standards for radio frequency identification (RFID) devices.

This document specifies the security services of an AES-128 crypto suite. AES has a fixed block size of 128 bits and a key size of 128 bits, 192 bits or 256 bits. This document uses AES with a fixed key size of 128 bits and is referred to as AES-128.

This document specifies procedures for the authentication of a Tag and or an Interrogator using AES-128 and provides the following features:

• Tag authentication;
• Tag authentication allowing authenticated and encrypted reading of part of the Tag’s memory;
• Interrogator authentication;
• Interrogator authentication allowing authenticated and encrypted writing of part of the Tag’s memory;
• Mutual authentication.

In this document, a Tag and an Interrogator can support one, a subset, or all of the specified options, clearly stating what is supported.
