An ECC-Based Algorithm to Handle Secure Communication Between Heterogeneous IoT Devices

Internet of Things (IoT) is an interconnection of tiny real-world objects using sensor, actuators, and software’s designed for exchanging data and controlling them. It invades business landscape on massive scale integrating heterogeneous devices. Some of the application includes media, environmental monitoring, infrastructure and energy management, medical, healthcare system, and transportation. Earlier, in these applications, the primary issue is handling efficient communication among the interconnected devices to have an extended network lifetime. Nowadays, as data grows rapidly in the IoT, security and privacy is also a major issue to be concentrated in these applications to reduce vulnerabilities. Recent studies show that the existing IP security protocols and algorithm have technical limitation in applying it to the context Internet of Things. In particular, when a new device enters to an existing secured network, the network should ensure that the new device is authenticated and authorized properly with respect to the properties of existing network. Otherwise, similar to other network, IoT network also will be subjected to various attacks such as physical attacks, service disruption attacks, data attacks, and denial-of-service attacks. Hence, in this work, an algorithm to authenticate and authorize when a new device gets added to the existing network is proposed. The algorithm is tested for various attacks and the results are proven to be efficient and secure.
