IoT

The Software Updates for Internet of Things (SUIT) Working Group is tackling one of the most pressing challenges in IoT security: reliable, secure, and interoperable firmware updates for constrained devices.

Today IoT deployments often depend on proprietary update mechanisms that are fragmented and difficult to audit. As vulnerabilities continue to emerge, security experts, researchers, and regulators agree: every IoT device should have a robust and standardized way to update firmware securely.

The IoTops (IoT Operations) WG at the IETF has a document called Terminology for Constrained-Node Networks, whose abstract is as follows:

"The Internet Protocol Suite is increasingly used on small devices with severe constraints on power, memory, and processing resources, creating constrained-node networks. This document provides a number of basic terms that have been useful in the standardization work for constrained-node networks." A new version of this document is dated 7 July 2025.

The IRTF draft titled "Guidance on RESTful Design for Internet of Things Systems"(https://datatracker.ietf.org/doc/draft-irtf-t2trg-rest-iot/) provides recommendations for applying REST (Representational State Transfer) principles to the design of IoT systems. REST is a well-known architectural style for building scalable and interoperable web services. This draft explores how those same principles can be adapted to the unique constraints and characteristics of the Internet of Things, where devices often have limited resources and operate in constrained networks.

We introduced LoRa mesh networks at in the GAIA WG meeting at IETF 122. Different to LoRaWAN, LoRa mesh networks are not standardized. The current proprietary solutions and open source solutions are not interoperable. The lack of standardization is a difficulty for a quicker adoption of LoRa mesh network technology.

The Internet-Draft titled "Comparison of CoAP Security Protocols" analyzes and compares the message sizes of key exchange processes and per-packet overheads associated with various security protocols used to secure the Constrained Application Protocol (CoAP). Minimizing message sizes is crucial in constrained radio networks, such as Low-Power Wide Area Networks (LPWANs), to reduce energy consumption, latency, and completion times.

The security protocols evaluated in this document include:

From Charter: "The Supply Chain Integrity, Transparency, and Trust (SCITT) WG will define a set of interoperable building blocks that will allow implementers to build integrity and accountability into software supply chain systems to help assure trustworthy operation.
