Enhancing data securit in IOT system using quorum blockchain network with IPFS protocol

Abstract

The Internet of Things (IoT) is an emerging technology. It enables users and various IoT-enabled devices to be linked across the IoT network to exchange their data and resources, resulting in a more relaxed and connected lifestyle. There are still several challenges facing the new centralized IoT network. For illustrative purposes, computing all connected nodes within the network relies on a centralized server. The centralized IoT model prompts a single point of failure when the central server is offline. The centralized IoT model is a clear target for privacy and security issues, as a centralized system completely handles all IoT data of several connected devices. The proposed framework consists of three significant contributions. newlineIn the first contribution, solving the problem of data security in the IoT System centralized database is highlighted. The current IoT System stores the data into centralized database such as MySQL, DB2 etc. The centralized system is faced with several challenges, for instance if the server crashes, the whole system will be unavailable. This case is known as a single point of failure. Implementing the Ethereum Blockchain Network in the IoT system will solve these problems. It provides an unchangeable ledger to ensure the reliability of transactions between linked nodes on a distributed blockchain network, thereby replacing the central authority. newlineIn the second contribution, the additional security and privacy for IoT Data in an existing Ethereum Network is added. Quorum Blockchain Network (QBN) is implemented with Tessera Transaction manager for private Transactions. Only permitted participants can view the data in the Quorum Network.
