An Exhaustive Review of Blockchain Based Approaches for Enhancing Security in Internet of Things Environment

Abstract

Bridging the currently available trust domain remains as the biggest challenge in internet of things. Block chains have newly fascinated the attention of shareholders through an extensive duration of industries: from finance to several utilities. It is a hopeful expertise for instituting trust in IoT networks, where network nodes do not inevitably trust each other. Recent explosion of the internet around block chains would remain as a stable fit for security in internet of things sector. The block chain technology could provide synchronized as well as secure transactions over multiple users and it offer perfect shared time stamped records which can't be modified by anyone. It permits distributed peer-to-peer network in which non-trusting members could communicate with one other without the need for trusted intermediary, in an authenticated manner. This current research work presents a comprehensive review of the background of Internet of Things (IoT), the scope of block chain based IoT security systems and the research problem prevailing in this field.
