IoT DNS DNS SECURE DNS NAMING METHOD FOR IOT DEVICE AND ROUTER APPARATUS FOR REGISTERING DNS NAME

摘要

The present invention provides a method for registering a domain name automatically generated by an IoT device to a DNS server. A method for naming a DNS having security with respect to the IoT device comprises the following steps of: a mobile terminal receiving a first key from an authentication server, and a domain name collecting device receiving a second key from the authentication server; the domain name collecting device receiving the domain name and a signature including model information from the IoT device; the domain name collecting device verifying the signature by decoding a digital signature into the second key; and the domain name collecting device registering a DNS name with respect to the IoT device to the DNS server if the verification is successful. The first key and the second key are asymmetry keys which are generated by the authentication server for authentication with respect to the IoT device, and the signature is generated by using the first key which is transmitted by the IoT device from the mobile terminal through local area communication.
