A Detail Dominant Approach for IoT and Blockchain with their Research Challenges

Abstract

Internet of things (IoT) is a pool of various devices, objects, humans, services those might be interconnected and that can communicate with each other, share data and information to succeed a common aim in different applications and areas. The idea of the IoT is to allow devices to work together on the Internet. In IoT now days the main issue is the security, in our paper we have found many research challenges related to our area and the security challenges of IoT faces are becoming more and more severe as IoT uses is growing in almost all applications. If IoT devices are not secured properly, the privacy and security of data will remain major issues in the present world in which things are interconnected. The main motive of our paper is to review the present research challenges related to IoT and the developments in the field of IoT security with Blockchain. Blockchain can be a very good option, it provides wide range of security solutions for IoT ecosystems, including trustworthiness, privacy, integrity, transparency, data availability. The Blockchain technology is basically based on the concept of decentralization, security and transparency of the system that has developed as a proficient technology to resolve the serious issues those generally occurred in the fundamental centralized networks and secure the IoT technologies. Some interesting research directions of the use of blockchain in IoT can be found in our very recent survey paper. In this work, the effects of the blockchain on an extensive range of IoT security from the latest research papers and at last a model has been provided for the security of IoT using blockchain.
