Advanced Secure DNS Name Autoconfiguration with Authentication for Enterprise IoT Network

Internet of Things (IoT) is an intelligent infrastructure and service technology that connects objects to people for monitoring and control. The number of IoT devices is rapidly increasing in various environments. Although the DNS protocol is being applied to IoT networks to create unique identifiers, it is burdensome for users to manually create and configure a globally unique name for each device. DNS Name Autoconfiguration (DNSNA) was proposed to register the DNS name of IoT devices automatically and utilize IoT devices globally. However, DNSNA without secure authentication and authorization leads to potential threats, such as the registration of malicious IoT devices, and other IoT security attacks. In this paper, we propose an Advanced Secure DNS name autoconfiguration with Authentication and Authorization for enterprise IoT network (ASDAI). Especially, we provide the first model using the convergence of extended OAuth 2.0 and Kerberos v5. The proposed protocol supports (1) reliable device / administrator registration, (2) secure DNS name autoconfiguration, and (3) user / service authentication and authorization procedure for the heterogeneity and scalability of enterprise IoT networks.
