DNS for IoT Security using IPv6

In a few short years, the Internet of Things (IoT) has gone from a technology — or set of technologies — that were cutting edge to the situation today where connected household items, or automobiles, are common. There are two main challenges associated with deployment of IoT devices in today’s Internet world.1. Limited address space of IPv4 and upgradation to IPv6 addresses are relatively slow. The operation of IPv6-only networks is still a new concept that needs to be explored.2. Security of IoT devices which are highly resource constrained and deployed typically in remote/difficult-to-access locations. Most of the IoT devices come with factory installed firmware. The firmware of IoT devices is not generally updated during their lifetime. So, they are more prone to attacks which may lead to severe problems. Hence, there is a need for mechanism to securely update software or firmware of these IoT devices.This project investigates suitability of using DNS infrastructure with DOA (Digital Object Arctitecture) record type for secure Over-The-Air (OTA) software / firmware updating of IPv6 based IoT devices.It's a collaborative project being executed by IIT Hyderabad and ERNET IPv6 team with funding and guidance by ICANN and NASSCOM
