Attribute-Based Encryption with Authentication Provider in FIWARE Platform

Abstract

This paper aims at presenting the approach for the process of attributes verification in the Attribute-Based Encryption schemes. We considered ABE methods in the Internet of Things environment. The main idea is to allow users or device owners to verify attributes using standardized and well-known authorization protocols like Oauth2. More accurately, Attribute Authority will use Authentication as a Service approach for users and device controllers authentication. We described software service for Attribute-Based Encryption methods in the context of FIWARE platform. Components of this platform use Oauth2 for authentication and authorization mechanisms. More specifically, we developed a web application which allows devices to create orders for ABE secret keys with particular attributes. Further users should approve or deny these orders. We used FIWARE components for users and devices authentication. To the best of our knowledge, it is the first implementation of ABE algorithms in FIWARE ecosystem.
