A Manifest Information Model for Firmware Updates in Internet of Things Devices
RFC 9124, “A Manifest Information Model for Firmware Updates in Internet of Things Devices”, is an Informational document published in January 2022 by B. Moran, H. Tschofenig, H. Birkholz. The canonical text is published by the RFC Editor.
Abstract
Vulnerabilities with Internet of Things (IoT) devices have raised the need for a reliable and secure firmware update mechanism that is also suitable for constrained devices. Ensuring that devices function and remain secure over their service lifetime requires such an update mechanism to fix vulnerabilities, update configuration settings, and add new functionality.
One component of such a firmware update is a concise and machine-processable metadata document, or manifest, that describes the firmware image(s) and offers appropriate protection. This document describes the information that must be present in the manifest.
