A Security-Enhanced Interoperability Middleware for the Internet of Things

Abstract

This paper documents an Internet of Things (IoT) middleware specially tailored to address the security, and operational requirements expected from an effective IoT platform. In essence, the middleware exposes a diverse palette of features, including authentication, authorization, auditing, confidentiality and integrity of data. Besides these aspects, the middleware encapsulates an IoT object abstraction layer that builds a generic object model that is independent from the device type (i.e., hardware, software, vendor). Furthermore, it builds on standards and specifications to accomplish a highly resilient and scalable solution. The approach is tested on several hardware platforms. A use case scenario is presented to demonstrate its main features. The middleware represents a key component in the context of the “GHOST - Safe-Guarding Home IoT Environments with Personalised Real-time Risk Control” project.
