Secure DNS name autoconfiguration for IPv6 internet-of-things devices

This paper proposes a Secure Domain Name System (DNS) Name Autoconfiguration called SDNSNA for IPv6 Internet-of-Things (IoT) Devices. The manual configuration of domain names of devices might be a cumbersome burden for users as the number of devices increases. A legacy scheme called DNS Name Autoconfiguration (DNSNA) can be used to register the DNS names of IoT devices automatically into a DNS system. However, DNSNA registers the DNS name of IoT devices without an authentication process. The DNS name registration of unauthenticated IoT devices can cause security problems. In this paper, we propose SDNSNA to support security functionality to let the legacy scheme of DNSNA provide secure DNS naming services to IoT devices. In SDNSNA, the smartphones of valid users can authenticate devices by interacting with an authentication server so that the devices can register their DNS names and the corresponding IPv6 addresses. Therefore, with a Near Field Communication (NFC)-based authentication, SDNSNA can provide users with secure and easy DNS name autoconfiguration of their IoT devices.
