Foreword
ISO (the International Organization for Standardization) and IEC (the International Electrotechnical
Commission) form the specialized system for worldwide standardization. National bodies that are
members of ISO or IEC participate in the development of International Standards through technical
committees established by the respective organization to deal with particular fields of technical
activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international
organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the
work. In the field of information technology, ISO and IEC have established a joint technical committee,
ISO/IEC JTC 1.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for
the different types of document should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject
of patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent
rights. Details of any patent rights identified during the development of the document will be in the
Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation on the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to the
World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see the following

This document was prepared by Technical Committee ISO/IEC JTC 1, Information technology,
Subcommittee SC 31, Automatic identification and data capture techniques.
This second edition cancels and replaces the first edition (ISO/IEC 29167-10:2015), which has been
technically revised.

Introduction
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 allows authenticated and encrypted reading of a part of the Tag’s memory;
— Interrogator Authentication;
— Interrogator Authentication allows authenticated and encrypted writing of a part of the Tag’s memory;
— Mutual Authentication.
Crypto suite only supports encryption on the Tag and uses encryption for “encrypting” messages sent
from the Tag to the Interrogator and “decrypting” messages received from the Interrogator.
The International Organization for Standardization (ISO) and International Electrotechnical
Commission (IEC) draw attention to the fact that it is claimed that compliance with this document
might involve the use of patents concerning radio-frequency identification technology
