A Firmware Update Architecture for Internet of Things

Overview

RFC 9019, “A Firmware Update Architecture for Internet of Things”, is an Informational document published in April 2021 by B. Moran, H. Tschofenig, D. Brown, M. Meriac. The canonical text is published by the RFC Editor.

Abstract

Vulnerabilities in Internet of Things (IoT) devices have raised the need for a reliable and secure firmware update mechanism suitable for devices with resource constraints. Incorporating such an update mechanism is a fundamental requirement for fixing vulnerabilities, but it also enables other important capabilities such as updating configuration settings and adding new functionality.

In addition to the definition of terminology and an architecture, this document provides the motivation for the standardization of a manifest format as a transport-agnostic means for describing and protecting firmware updates.
