Reshaping IOT Through Blockchain

Abstract

From the beginning of crypto currency in 2008, blockchain technology rise as progressive technology. Block chain technology was began as a core technology of bitcoin, but it is growing to numerous fields such as, security of Internet of Things (IoT), transport sector, robotics, smart energy, banking sector, industries, insurance, medical etc. Currently more businesses are moving through online system. The digitization of data can be carried through the centralization and decentralization process with higher protection. All the data can be stored through blocks with transaction history as block chain. Unfortunately, In a block chain the transaction can be simplified with peer-peer network that excludes the involvement of third party. Today as a world is going towards automation and smart objects internet of things(IoT) has gained popularity due to its usage in smart homes, smart farming, and smart city projects around world. Unfortunately, internet of things devices possess, low compatibility, high complexity, limited computing power, low security, low storage capability and network capacity therefore internet of things devices are more prone to attacks than other components such as phones, ipods, tablets, or PCs. This paper focus on identifying significant security and privacy issues for IoT, proposing anew IoT model through block chain technology and implementing the proposed model for solving IoT issues through block chain technology. Block chain technology can be a key empowering influence to take care of numerous IoT privacy and security issues. Finally describe the future work directions.
