Implementing secure smart home using existing infrastructure

Abstract

The emergence of Internet of Things [IoT] paves the path of the smart home.  A smart home learns the habits of residents to make intelligent decision, which requires knowledge to be communicated and stored. The communication of generated data creates loop-hole in security and privacy of the user of smart home. Another challenging issue while designing a smart home is that legacy home appliances lack the smart connectivity. This paper focuses on designing a secure architecture to access smart home appliances, while using the existing home appliances that lacks networking and processing power like a bulb or fan. To ensure secure communication using internet, we are using third party authentication tool deployed in cloud. We have installed a gateway as the entry point to our smart home and connected all the appliances to it. The user is authenticated by authentication server and gets access to the services. For implementation purpose, we used Kerberos as authentication tool and DragonBoard as gateway.
