> This technology has enormous implications for consumers and organizations alike. For consumers, it spells a more seamless way of interacting with the devices used in day-to-day life. Likewise, many industries across the globe are increasingly turning to IoT to automate business processes, support the development of interoperable value chains, and enhance asset management.

> As the world becomes even more connected and more machines are hooked up to the internet, the ability for machines to move, trade and interact securely and efficiently becomes increasingly important to life and business. Today’s centralized networks do not enable this. Machines today exist on closed, permission-based environments which massively limit which other machines can be interacted with, what machines can do and where they can go.

> Managing IoT devices and user identities as well as the relationships among various devices and their digital twins face significant challenges. First, a lack of Identity Credential and Access Management (ICAM) standards for IoT creates proprietary standards and a lack of interoperability. Second, the operational lifecycle of IoT devices complicates integration of traditional ICAM. Lastly, ICAM technology must adapt to the proliferation of connected devices. This evolution requires a digital trust framework and the decentralized architecture of Self-Sovereign Identity (SSI).

> Unlike a Wifi network, you don't put the network credentials in the device, you put the devices credentials (keys) in the network. Once I'd done that, the sensor started connecting to hotspots near my house and transmitting data. Today I've been driving around with it in my truck and it's roaming onto other hotspots as needed, still reporting temperatures.

> The ETO GRUPPE has set itself the goal of automating communication in the Internet of Things (IoT) and, on top of that, making it more secure against access and manipulation. To achieve this, these "things" - machines, devices or vehicles - must first be given a unique identity. The solution of the innovative corporate group consists of a new type of network and authentication processes that have what it takes to revolutionize the way we use the Internet today. ETO uses a network of distributed digital identities (DIDs) and verifiable credentials (VCs). A side benefit from the perspective of human Internet users: they regain data sovereignty over their personal data.

P. Costa, Samira Afzal, Jan M. Rabaey, Roseli D. Lopes, Marcelo K. Zuffo
> One of the challenges identified by this last paper is the overhead of using SSI, which poses a challenge for adoption on constrained IoT networks. For example, while the Long Range (LoRa) communication, often used in IoT systems, only allows payloads of up to 240 bytes, a single DID Document typically occupies 500 bytes or more. Similarly, messages using DIDComm tend to use at least 1 kilobyte, which prevents its use on constrained networks.<br>Figure 1. Binary versions of DIDComm and DID Documents are needed to allow transmission in LoRa networks. The payload, in blue, is a DID Document. The overhead, in orange, is the protocol overhead due to the message signature.

> A low-overhead approach for self-sovereign identity in IoT We present a low-overhead mechanism for self-sovereign identification and communication of IoT agents in constrained networks. Our main contribution is to enable native use of Decentralized Identifiers (DIDs) and DID-based secure communication on constrained networks, whereas previous works either did not consider the issue or relied on proxy-based architectures. We propose a new extension to DIDs along with a more concise serialization method for DID metadata. Moreover, in order to reduce the security overhead over transmitted messages, we adopted a binary message envelope. We implemented these proposals within the context of Swarm Computing, an approach for decentralized IoT. Results showed that our proposal reduces the size of identity metadata in almost four times and security overhead up to five times. We observed that both techniques are required to enable operation on constrained networks.

> This paper analyses the concept of Self-Sovereign Identity (SSI), an emerging approach for establishing digital identity, in the context of the Internet of Things (IoT). We contrast existing approaches for identity on the Internet, such as cloud-based accounts and digital certificates, with SSI standards such as Decentralized Identifiers (DIDs) and Verifiable Credentials (VCs). To the best of our knowledge, this is the first thorough comparison of these approaches. The benefits and challenges of using DIDs and VCs to identify and authenticate IoT devices and their respective users are discussed. In the end, we establish that SSI, with its owner-centric, privacy-aware and decentrailized approach, provides a viable and attractive option for secure identification of IoT devices and users.

> in our point of view, a lot of development groups are working in parallel on the similar topics, yet it is not clear what is going on inside. In this paper we will try to define the differences and discuss both pros and cons of using such commonly known technologies as Sovrin based upon the Hyperledger Indy technology, Civic, Jolocom, uPort and some others. Besides, we’ll tackle the idea of using the SSI for inanimate object and how it can be constructed in this way.
