Description (English):

ISO/IEC 29167-14:2015 defines the cryptographic suite for AES using OFB mode (AES OFB) for the ISO/IEC 18000‑63 air interface standard for radio frequency identification (RFID) devices. Its purpose is to provide a common cryptographic suite for security for RFID devices that can be referenced by ISO committees for air interface standards and application standards. ISO/IEC 29167-14:2015 specifies a cryptographic suite for AES OFB for air interface for RFID systems. The cryptographic suite is defined in alignment with existing air interfaces. ISO/IEC 29167-14:2015 defines various authentication methods 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.

Abstract

Overview

ISO/IEC 29167-14:2015 specifies a cryptographic suite using AES in Output Feedback (OFB) mode - commonly referred to as AES-OFB - for secure air interface communications of RFID systems. Designed to complement the ISO/IEC 18000‑63 air interface (RFID Type C), this part of ISO/IEC 29167 provides a standardized, interoperable method for adding strong cryptographic protection to tag–interrogator exchanges. The standard is intended as a reference cryptographic suite that ISO committees and application developers can invoke when security for RFID air interfaces is required.

Key topics and technical requirements

AES-OFB cipher description and operation: Defines encryption/decryption behavior in OFB mode suitable for continuous data streams between interrogator and tag.
Authentication methods: Specifies multiple authentication types (e.g., tag authentication, interrogator authentication, mutual authentication, and initialization/authentication procedures) and the required command/response flows.
Conformance rules: Clear requirements for claiming conformance; what interrogators and tags must implement (mandatory vs optional features).
State and protocol behavior: State diagrams, state transition tables, initialization/reset rules, and protocol-specific operation to ensure predictable interoperable behavior.
Key management: Master key selection, keystream generation, and key update mechanisms tailored to RFID constraints.
Operational details and tooling: Includes normative annexes for cipher description, error codes, protocol operations and informative annexes with AES-OFB test vectors to support implementation and testing.

Practical applications

ISO/IEC 29167-14:2015 is targeted at applications that require confidentiality, integrity and authentication over the RFID air interface, particularly where large volumes of data may be exchanged or where the unique item identifier (UII) must be protected. Typical use cases include:

Secure supply‑chain and inventory management (protecting item identifiers and sensitive read/write operations)
Asset tracking and access control systems that require authenticated RFID interactions
