Summary - Y.4815 (05/2026) - Framework of unified authentication service for data collaboration in Internet of things (IoT)-based electric power infrastructure

In an IoT-based electric power infrastructure (IoT-EPI), data collaboration across different information systems is common for applications and plays a key role in supporting operations such as data analysis, operational optimization, and decision-making. Traditionally, applications must develop separate authentication modules for each information system, leading to high costs, complexity and a larger attack surface.
Recommendation ITU-T Y.4815 specifies a unified authentication (UA) service for data collaboration in IoT-EPI, including its characteristics, requirements, functional architecture, capabilities, and general procedures.
