Ítem Implementing secure smart home using existing infrastructure(Universidad Icesi, 2017-06-12) Kumar, SunjayThe 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.Ítem Token-Based Authentication Techniques on Open Source Cloud Platforms(Universidad Icesi, 2018-10-01) Banerjee, AmitCloud computing is a service-oriented computational platform that allows on-demand resource provisioning for low-cost application deployment. However, security and privacy of the users is a major concern for the cloud service provider, particularly for applications handling users personal information (health record, GPS location) or performing financial transactions. Authentication is an important security measure for establishing accountability and authorization of the users, is often a prerequisite for accessing cloud-based services. In this paper, we mainly focus on the token-based authentication techniques, supported by popular open source cloud platforms [OSCPs], like Cloudstack, OpenStack, Eucalyptus and OpenNebula. In general, most OSCPs support the basic text-based user authentication. Other techniques, such as biometrics, gesture and image, can also be implemented on OSCPs. However, in this paper, we choose to discuss the token-based authentication, as it allows users to gain access to multiple cloud services with a single sign-on (SSO). Moreover, token’s can be shared among multiple users for accessing cloud-based services..
