Spider Web-based Dynamic Key for Secured Transmission and Data-Aware Blockchain Encryption for the Internet of Things

Abstract

In the developed field of information and communication systems, the utilization of the Internet of Things (IoT) devices is greatly increasing. In their applications, data gathering with limited energy consumption and good security is essentially needed nowadays. The network is energy limited as the sensor nodes are operated using battery power. The nodes in the network are vulnerable to several attacks and the proposed data transmission scheme should provide network security. Security is a main concern in data aggregation. In this work, a secured data aggregation scheme with compression technique and blockchain-based encryption added routing is presented. The data transmitted by the device are added with a hash key generated using a spider web-based dynamic key (SWDK) generation process. The SWDK-added compressed data are transferred in the process of blockchain encryption routing. Then compression-based data aggregation is utilized to reduce the data size and sequentially the transmission cost. The devices in the network transmit data to the base station/server in the network through gateways. The simulation results prove that the proposed work gives reduced transmission cost and energy consumption compared with the existing works. The network throughput increases due to the sharing of security keys, as well as network latency and packet dropping, which are reduced in the proposed work.
