An architecture for secure provisioning and usage of IOT services

Abstract

The growth in the internet of things plays a central role in the future internet having a common platform for a complex network of computers, wired and wireless sensors, actuators and radio frequency identification devices. Our simplified view of this complex network is of a ‘network that provides various services’; let’s call it the internet of services. There is though a lack of a platform that can bring together the services offered by the internet of things/internet of services and the future user of these services. In this thesis, an architecture has been proposed for providing secure services to connected users. We propose a layered architecture that has an application layer, a service layer and a sensing-network layer to accommodate the requirements of the internet of services in a timely and effective manner. In this architecture, the end to end data communication security of the internet of services has been taken into consideration. A web security interface has been introduced, which provides security for user credentials. This interface is introduced in the application layer to protect and ensure data communication security using a single sign on. We have proposed a node to node communication security solution after considering the vulnerabilities and threats around connecting a future integrated service. We have designed and evaluated our architecture by performing a range of experiments. These experiments were conducted using database connection round trip time, total execution code round trip time and average query round trip time to compare the services that were designed on different programming platforms.
