Symmetric cryptography for secure communication in IoT

Abstract In science and innovation, material engineering is a diverse set of things or conceptual patterns, including postulates, research techniques, theories and criteria on what cnidarians improvements to an area. Smart devices are made by smart materials as well as smart materials made by such as carbon, fibre and graphene. Smart devices are interconnected to transfer the data. Graphene is one of the material to use in smart healthcare over IoT. Graphene's distinctive characteristics, its low energy consumption and the potential to sustain intense data speeds, can make it attractive in many modern IoT applications. The Internet of Things (IoT) is an evolving world-view in which the devices around us are interconnected to provide smooth, fast and efficient communication and contextual amenities. In the IoT, due to the limitless number of devices, each device cannot be authenticated in a short time. Similarly, receiving their authentication request at the same moment is hard. Therefore it is necessary to have a safe and efficient authentication system that authenticates devices in the context of resource-restricted IoT at once. This paper presents a novel and efficient cryptography based authentication over some advanced matrix techniques for the IoT which verifies the authenticity of the devices taking part in the communication.
