Secured Internet of Things (IoT) Model using Blockchain

Abstract

Anything which is connected to the internet is prone to threats. The internet has a saying that, ”There are two types of hacked devices. One which is hacked, and the other one is which does not know that it is hacked”. Security and privacy of valuable data have been a major issue over decades. Researches based on IoT device security is going around for quite a good time in this era and still has many scopes to build a more secure, data, and privacy protected IoT system. As beneficial as internet-connected devices are, they create some significant challenges. While we assume that these devices are protected with the same security level as the typical network server, it is not the case. IoT devices present some major security concerns, which we will talk about in broad. Blockchains can be a solution for securing IoT devices. Blockchain is a cryptographically secured, distributed ledger technology that allows for secure data transfer between parties. Blockchain is surely one of the promising and revolutionary technologies of this era because it reduces risk, stamps out fraud, and brings transparency in a scalable way for many uses.
