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.
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 or
www.iec.ch/members_experts/refdocs).
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) or the IEC
list of patent declarations received (see https://patents.iec.ch).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of 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
www.iso.org/iso/foreword.html. In the IEC, see www.iec.ch/understanding-standards.
This document was prepared by Joint 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 29167-16:2015), which has been
technically revised.
The main changes are as follows:
— certain normative references have been updated;
— editor ial and technical rev isions have been made to maint ain confor mance w it h ISO/IEC 18000-4:2018.
A list of all parts in the ISO/IEC 29167 series can be found on the ISO and IEC websites.

Introduction
The International Organization for Standardization (ISO) and the International Electrotechnical
Commission (IEC) draw attention to the fact that it is claimed that compliance with this document may
involve the use of a patent.
ISO and IEC take no position concerning the evidence, validity and scope of this patent right.
The holder of this patent right has assured ISO and IEC that he/she is willing to negotiate licences under
reasonable and non-discriminatory terms and conditions with applicants throughout the world. In this
respect, the statement of the holder of this patent right is registered with ISO and IEC. Information may
be obtained from the patent database available at www.iso.org/patents or https://patents.iec.ch.

Part 16:
Crypto suite ECDSA-ECDH security services for air interface
communications
1 Scope
This document describes a crypto suite based on elliptic curve cryptography (ECC) for the
ISO/IEC 18000 series of standards protocol. In particular, this document specifies the use of elliptic
curve Diffie-Hellman (ECDH) key agreement in a secure channel establishment and the use of elliptic
curve digital signature algorithm (ECDSA) in an authentication mechanism.
This document specifies a crypto suite for ECDSA-ECDH for air interface for RFID systems. The crypto
suite is defined in alignment with existing air interfaces.
This document defines a mutual authentication method 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.
Key update is not supported in this document.
ECDSA-ECDH cipher is a high-weight security protocol especially for active RFID system, aiming at
meeting those scenarios with high level security requirement.
