  • Why Machines Need Self-Sovereign Identities 2021-10-18 Peaq

    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.

  • Digital Twins and Self-Sovereign Identity: Build the next generation of Simulation with privacy preservation 2021-07-30 IOT Practicioner

    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).

  • Alternatives to the CompuServe of Things 2021-07 Phil Windley

  • [Video] Distributed Ledger Technologies, IAM, and the Truth in Things 2019-06-27 Identiverse Robert Brown

    Safety and security rests with all involved in authorizing updates, how and when they are applied as well as the right to repair when Things are no longer officially supported. Shared device lifecycle assurance is the basis for verifiable service histories of Things which give data provenance. When data can be proven to originate from reliable sources, its value increases while reducing the risk of using it. Enabling third parties to build value from data would unlock the true value of IoT which in turn could fund its upkeep. This talk will outline how identity and shared ledger technology have key roles to building Truth in Things for a sustainable IoT.

  • Juicy Telemetry 2022-04-04 Wilder Team

    I was in a Sovrin IoT call when I heard the phrase “juicy telemetry.” A digital twins product leader was bemoaning all the really good data held back by the manufacturers of equipment. Data they needed to properly model their twins, to keep them current, to validate their assumptions. For good and bad reasons, the makers of wind turbines and cars and ship engines and weather sensors choose to hide data.

  • Easier IoT Deployments with LoraWan and Helium 2022-04 Phil Windley

    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.

  • Rugged Identity: resilience for Identity of Things to bad latency, signal, power, physical integrity. Mars, war zones, bad neighbors, Great Firewalls. 2021-05-06 Phil Wolff

    Problem: So, what happens when you can’t call home to conduct an identity conversation? You’re on Mars and the latency is long. You’re in Haiti and the bandwidth is very limited during a storm. You’re in a war zone and your signal is noisy due to interference.

    Rugged Identity is hoped-for resilience from very long latency, noisy signal, low bandwidth, interrupted connections, very low power computing and radio, power outages, and attacks on physical integrity like device tampering.

  • [Presentation] IoT Swarms + SSI in constrained networks 2021-07-21 sourcepaper Geovane Fedrecheski, Laisa C. 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.
    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.

  • Self-Sovereign Identity for IoT environments: A Perspective 2020-03-11 Geovane Fedrecheski, Jan M. Rabaey, Laisa C. P. Costa, Pablo C. Calcina Ccori, William T. Pereira, Marcelo K. Zuffo

    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.
