Summary

Recommendation ITU-T Y.4811 defines a converged service for identification and authentication for Internet of things (IoT) devices in a decentralized environment (CSIADE), and provides its common characteristics, general requirements, functional architecture, key capabilities and procedures. CSIADE allows IoT devices and IoT services to identify and authenticate each other — whether they use the same or different types of identification and authentication solutions — within decentralized environments.

This Supplement provides a set of implementation guidelines for performing CSIADE as described in Recommendation ITU-T Y.4811. The guidelines include:

-       that of CSIADE as a standalone system and as a subsystem embedded in Internet of things (IoT) devices and services,

-       to improve compatibility when using self-resolving identities for IoT devices and services,

-       to use self-controllable storage to manage identities of IoT devices and services,

-       to support online and offline endorsement for the identity of IoT devices and services, and

-       to support multiple solutions of identification and authentication in CSIADE.

This Supplement is designed to promote the adoption and deployment of CSIADE.
