Secure communication between groups of Smart IoT devices over the IPv6 network

With the increase in the enormous IoT application, achieving communication between these devices is becoming an important topic for research. The internet of things (IoT) architecture includes the interconnection of different types of end-user devices that communicate over a shared public network that generally runs over TCP/IP protocol. The core network contains routers that run routing protocols like OSPF, IS-IS, and BGP. The smart IoT devices have a TCP/IP stack built into them and these devices communicate with the core network using TCP/IP protocol. This paper proposes a method by which smart IoT devices can be segregated into groups and each group of devices communicates independently which ensures data belonging to one group does not interfere with data belonging to another group thereby providing isolation between groups. This paper proposes an enhancement to the existing network routing protocols (BGP) to advertise group information.
