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

Technical Barriers to Trade (TBT) see the following URL: www.iso.org/iso/foreword.html.
ISO/IEC 13157-4 was prepared by Ecma International (as ECMA-410) and was adopted, under a
special “fast-track procedure”, by Joint Technical Committee ISO/IEC JTC 1, Information technology, in
parallel with its approval by national bodies of ISO and IEC.
ISO/IEC 13157 consists of the following parts, under the general title Information technology —
Telecommunications and information exchange between systems — NFC Security:
— Part 1: NFC-SEC NFCIP-1 security services and protocol
— Part 2: NFC-SEC cryptography standard using ECDH and AES
— Part 3: NFC-SEC cryptography standard using ECDH-256 and AES-GCM
— Part 4: NFC-SEC entity authentication and key agreement using asymmetric cryptography

Introduction
The NFC Security series of standards comprise a common services and protocol Standard and NFC-
SEC cryptography standards.
This NFC-SEC cryptography Standard specifies an NFC Entity Authentication (NEAU) mechanism that
uses the asymmetric cryptography algorithm (NEAU-A) for mutual authentication of two NFC entities.
This International Standard addresses entity authentication of two NFC entities possessing certificates
and private keys during key agreement and key confirmation for the Shared Secret Service (SSE) and
Secure Channel Service (SCH).
This International Standard adds entity authentication to the services provided by ISO/IEC 13157-3 (ECMA-
409) NFC-SEC-02.
This International Standard refers to the latest standards.
The holders of these patent rights have assured the ISO and IEC that they are willing to negotiate
licences under reasonable and non-discriminatory terms and conditions with applicants throughout the
world.
In this respect, the statements of the holders of these patent rights are registered with ISO and IEC.
