A federated authentication and authorization approach for IoT farming.

IoT devices can be applied in diverse domains, including farming to maximize CAPEX and OPEX costs. Despite the increased gain in production through IoT, there are still challenges that need to be properly tackled for wider adoption. Traditional authentication and authorization mechanisms cannot be blindly applied to IoT due to the associated limitations. This tutorial presented a solution for an IoT Farm scenario, with multiple authentications across different geographic locations with a centralized identity provider and application in the cloud, and IoT devices on the edge. The proposed approach relies on standard protocols and tools, like Keycloak, as the identity management solution. By using OpenID Connect (OIDC), we can assure a secure federated authentication and authorization of both users and IoT devices for IoT farming scenarios.
