Dynamic Group Key Management Technique in Context of Modern IoT Applications

Abstract

Wireless Sensor technology research is becoming more popular in studying the Internet of Things (IoT) area. Sensor technology helps to collect information from the environment that can be used to analyze the system and helps to enhance the system's overall performance. The Internet of Things, a collection of linked devices, has become a new research topic for sensor technology. Quality of service (QoS), data routing, real-time monitoring performance, and connecting heterogeneous devices are difficulties faced by the Internet of Things security concerns. These networks are concerned about the wearable devices' short battery life, limited range, and limited capacity. Because of the wide variety of assaults that may be conducted against them in the real world, the security of Internet of Things devices is a complex problem to solve. As a consequence, particular standards for devices linked to the Internet of Things are needed. The sensor network must choose the most appropriate encryption technique from various choices to allow secure communication between sensor nodes. The proper operation of encrypted communications necessitates the use of keys. As a result, they must be developed and distributed. The present key management method is linked with significant computational overheads since it consumes a lot of energy and takes a long time to finish. As a result of the restricted bandwidth capacity of the sensor nodes in the network, the network is inefficient. IoT controllers are responsible for controlling a group of networks, and this article describes a method for dynamic key management that is both dynamic and scalable. Packet loss has been reduced by a significant proportion when compared to a conventional one-hop key management scheme. The suggested approach reduces energy consumption, computational overheads, and latency, all of which help to enhance network performance.
