Registering, managing, and communicating with iot devices using domain name system processes

Abstract

Provided herein is a method for registering an IoT device with a DNS registry. The method can include obtaining, at a DNS server, an identifier, IP address, and a public key of an asymmetric key pair associated with the IoT device from a network gateway device that is in communication with the IoT device, wherein the asymmetric key pair is provisioned onto the IoT device and an associated private key stored within a memory of the IoT device at a time that IoT device is manufactured or during a predetermined time window after manufacturing; creating at least one DNS record for the IoT device; assigning a domain name associated with the internet protocol (“IP”) address to the IoT device; storing the identifier, IP address, the domain name, and the public key in the at least one DNS record; and providing confirmation of the registration to the IoT device.

1 . A method of authenticating a message produced by an internet of things (“IoT”) device, the method comprising:
 obtaining the message from an IoT device, the message having been cryptographically signed by a private key of an asymmetric key pair associated with the IoT device and the message comprising an identifier of the IoT device and a data payload; 
 obtaining a public key of the asymmetric key pair stored in at least one domain name system (“DNS”) record associated with the IoT device; and 
 authenticating the message using the public key.
