Design of secure session key using unique addressing and identification scheme for smart home Internet of Things network

Internet of Things (IoT) defines as internetworks of physical smart devices embedded with electronic software, sensors, actuators, and network connectivity. Due to an increase in the number of smart devices, objects, and appliances, the existing addressing schemes and security protocols cannot guaranty to perform well in all situations. The main requirement includes a unique secure unique addressing scheme that ensures data privacy and reliable communication in the IoT system. In this article, a secure session key unique addressing and identification scheme proposed by modifying the standard IPv6 protocol. The proposed scheme provides a unique way of assigning the addressing for smart devices/appliances and uniquely authenticates them at the destination end. In addition, this scheme also establishes a secure session and mutual authentication by using the Diffie-Hellman key exchange protocol. The network simulation of the proposed scheme simulates network throughput and end-to-end delay. Moreover, the informal security verification and formal security analysis with the help of the ROR model carried out in this work. This analysis proves that the proposed scheme is safe against various possible attacks, for example, device impersonation, password guessing, man-in-the-middle, attacks replay, masquerade attacks, maintain anonymity, and secure end to end mutual authentication.
