Information technology — Automatic identification and data capture techniques — Part 15: Crypto suite XOR security services for air interface communications

ISO/IEC TS 29167-15:2017 defines a coding suite based on an exclusive or (XOR) operation for the ISO/IEC 18000 air interfaces standards for radio frequency identification (RFID) systems. In particular, it specifies the use of XOR as a basic way to hide plain data in the identity authentication and secure communication procedures. The coding suite is defined in alignment with existing air interfaces. ISO/IEC TS 29167-15:2017 defines various authentication methods and methods of use for the XOR. A tag and an interrogator may support one, a subset, or all of the specified options, clearly stating what is supported.

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.

Introduction
This document defines a coding suite based on an exclusive or (XOR) operation for the ISO/IEC 18000
air interfaces standards for radio frequency identification (RFID) devices.
XOR is a type of logical disjunction on two operands that results in a value of true if exactly one of the
operands has a value of true. The primary advantage of XOR operation is that it is simple to implement
and that the XOR operation is computationally inexpensive for hiding information in cases where either
no particular or light security is required. The simple implementation of XOR does not require a cipher
and therefore limits the security protection and attacks like eaves dropping are much easier.
The security service tag authentication is a mandatory security service. All other services in this
coding suite are optional. Every manufacturer has the liberty to chose which of these services will be
implemented on a tag.
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 may
involve the use of patents concerning radio-frequency identification technology given in the clauses
identified below.
ISO and IEC take no position concerning the evidence, validity and scope of these patent rights.
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.
