Securing Internet of Things (IoT)

Abstract

The Internet of Things (IoT) is our future and human life is now entering in to a generation where everyone will be using sensory information and artificial intelligence to make day to day life decisions in real-time. With implementation and enhancements around Internet protocol (IP) now it’s possible to connect and control these devices from anywhere around the globe they can be control by either human or even machines. Security is a critical element and building block for Internet of things (IoT) success. First, we have worked finding out possibility of detecting different types of attacks in Internet of things Wireless networks and identify them based on throughput, delay and energy consumed. Attack that we have work on include DOS attacks and DDOS attacks. Motivated by current use of Blockchain in resolving various problems we have evaluated its implementation to find solutions to secure Internet of Things. This become possible by utilising block chain network and smart contracts to validate any IoT communication . Using Blockchain network allowed IoT to detect securely authenticate without over utilizing device resource keeping in mind the limited hardware and bandwidth. IoT node or nodes communicates to a validator node within Blockchain network to get the most current binary of contracts status and in order to achieve this all the devices required to be in sync with Blockchain version of accounts stored by this validator node. We have worked out how this communication will work in order to ensure security and privacy while doing performance analysis of overheads. In conclusion IoT and Blockchain combine together is very promising solution to solve many current security issues in order to take it to mass scale deployment which allow implementation of Internet of things for a purposeful manner.
