Preventing Data Counterfeiting Among Internet of Things (IoT) Devices using Ethereum Blockchain

In today's world we are surrounded with lot of IoT devices and sensors. This IoT devices has made our life easier and more comfortable utilizing the Blockchain and increase the security and efficiency of network. key features of Blockchain will bring resistance to unauthorized modification and devices. The Rapid development in this technology of IoT is getting into pool and Rapid more data is transmitted and process over the communication channels. As a result, these devices is deployed worldwide and even more advanced requirement in the practical application and performance. Most of the devices are highly centralized architecture and which then suffers from technical limitation as well as they suffer from cyber attacks. To solve this problem, we propsed a system in which a gateway is introduced. The role of the Gateway in smartphones is the most beneficial, yet it is a unified structure that presents many security issues such as integrity, certification and availability. This network consists of three levels, including smart home devices, gateways and clouds. Blockchain infrastructure is provided in the gateway layer so that data can be processed and shared as blocks. Blockchain guarantees the confidentiality of internal data outside smart homes and the availability by way of authentic communication between the application of the network for Ethereum-based Blockchain technologies, including time and precision, to promote decentralization and overcome the central architecture issue.
