An automatized Identity and Access Management system for IoT combining Self-Sovereign Identity and smart contracts
This addresses security and interoperability issues for IoT users, but it appears incremental as it combines existing technologies like self-sovereign identity and smart contracts.
The paper tackled identity and access management for IoT systems, specifically smart vehicles, by proposing a blockchain-based system using Ethereum and Hyperledger Indy with a self-sovereign identity model, resulting in a portable solution that meets IoT requirements.
Nowadays, open standards for self-sovereign identity and access management enable portable solutions that are following the requirements of IoT systems. This paper proposes a blockchain-based identity and access management system for IoT -- specifically smart vehicles -- as an example of use-case, showing two interoperable blockchains, Ethereum and Hyperledger Indy, and a self-sovereign identity model.
