Blockchain-based Identity and Access Management in Industrial IoT Systems

It's been ten years since blockchain technology was created. This amalgam of cryptography and peer to peer application brings many innovations and securities services beyond financial services to regular information systems and offers new use cases for distributed applications. Industrials Internet of Things systems have issues with delivering identities to devices, controlling access or managing a vast amount of data. In this paper, we will go through the benefits a blockchain infrastructure can bring to the industrial Internet of Things (IoT) systems and present a new approach for a distributed Identity and Access Management (IAM) using blockchain technology as the communication layer. The proposed work in progress architecture is suited for consortium of companies sharing a fleet of IoT devices. The blockchain ensures the integrity and the non repudiability of instruction at destination to the IAM controllers.
