Full title and description

IEC 63563-9:2025 — Qi Specification version 2.0 — Part 9: Authentication Protocol. This international standard defines the architecture and the application‑level messaging used for authentication between a Power Transmitter (PTx) product and a Power Receiver (PRx) to ensure the PTx is Qi certified and originates from a registered manufacturer.

Abstract

IEC 63563-9:2025 specifies the authentication protocol for the Qi v2.0 wireless power ecosystem. It describes the protocol roles, message flows, required data elements and cryptographic considerations needed for a PRx to verify that a PTx is both Qi-certified and associated with a registered manufacturer, enabling secure interoperability across vendors.

General information

• Status: International Standard (published / current publication).
• Publication date: 14 February 2025 (IEC publication).
• Publisher: International Electrotechnical Commission (IEC).
• ICS / categories: 29.240.99, 35.240.99 (equipment related to power transmission and IT applications in other fields).
• Edition / version: Edition 1.0 (2025).
• Number of pages: 93 pages (IEC webstore listing for the base publication).

Scope

This document defines the architecture and application‑level messaging for the Authentication of a Power Transmitter Product by a Power Receiver within the Qi v2.0 specification. It covers the roles, message sequences, required data objects and the conditions under which a PRx may accept or reject a PTx based on certification and manufacturer registration status. The scope is limited to authentication; it does not itself specify full conformance test procedures (except where noted) or physical-layer power-transfer characteristics.

Key topics and requirements

• Authentication architecture and protocol roles (PTx, PRx and any supporting services).
• Application‑level message formats and sequences for authentication transactions.
• Required data elements and metadata to prove Qi certification and manufacturer registration.
• Cryptographic requirements and recommendations for message integrity and anti‑spoofing.
• Interoperability requirements for implementers to ensure cross‑vendor operation.
• Statements on error handling, timeouts and failure modes for authentication exchanges.
• Conformance considerations and references to related Qi parts for testing and profile alignment.

Typical use and users

Primary users are wireless power product designers and firmware engineers implementing Qi v2.0 PTx and PRx devices, test laboratories and conformity/certification bodies evaluating authentication behavior, security architects integrating device identity and trust, and product managers coordinating multi-vendor interoperability. The standard is maintained under the TC 100/TA 15 (Wireless Power Transfer) work area and is intended for use across consumer and commercial wireless power products.

Related standards

IEC 63563 is published as a multipart Qi specification. Relevant related parts include IEC 63563‑1 (Introduction and general requirements) and IEC 63563‑10 (MPP System Specification / Magnetic Power Profile extension). National and regional adoptions exist (EN IEC / BS EN / UNE‑EN versions) where Part 9 has been endorsed for regional use.

FAQ

Q: What is this standard?

A: IEC 63563‑9:2025 is Part 9 of the IEC 63563 Qi Specification v2.0 and defines the authentication protocol used to verify a power transmitter’s Qi certification and registered manufacturer status.

Q: What does it cover?

A: It covers protocol architecture, message formats and sequences, required data elements, and cryptographic considerations for authentication between PTx and PRx devices. It is focused on the application‑level authentication exchange rather than physical power-transfer parameters.

Q: Who typically uses it?

A: Device manufacturers, firmware and security engineers, conformity assessment bodies and test labs use this standard to implement and verify authentication behavior in Qi‑compliant wireless power products.

Q: Is it current or superseded?

A: IEC 63563‑9:2025 was published in February 2025 (Edition 1.0) and is listed as the current edition. Its published stability date is 2026; it should be treated as current as of 25 February 2026 unless a newer amendment or edition has been published after that date. Consult the IEC webstore or your national standards body for any updates beyond that date.

Q: Is it part of a series?

A: Yes — IEC 63563 is a multipart Qi specification (several parts covering introduction, profiles, system specifications and authentication). Examples include IEC 63563‑1 (Introduction) and IEC 63563‑10 (MPP System Specification). Regional/adopted versions (EN IEC / BS EN / UNE‑EN) mirror the IEC text where endorsed.

Q: What are the key keywords?

A: Qi v2.0, authentication, wireless power, PTx, PRx, manufacturer registration, interoperability, IEC 63563.
