IoT security Review blockchain solutions and open challenges

Minhaj Ahmad Khancompleted his M.S. and Ph.D. degrees in Computer Science from University of Versailles, France. He also holds a post-doc from University of Bordeaux-I, France. He is currently working as Associate Professor at Bahauddin Zakariya University, Multan. His research interests include Computer Networks and High Performance Computing. He has several publications in prestigious journals and conferences on these topics.

A review of emerging topics related to Internet of Things (IoT) security and Blockchain is presented.

Blockchain technology and its robust solutions for challenging and critical IoT security problems are reviewed.

In this paper, we present and survey major security issues for IoT. We review and categorize popular security issues with regard to the IoT layered architecture, in addition to protocols used for networking, communication, and management. We outline security requirements for IoT along with the existing attacks, threats, and state-of-the-art solutions. Furthermore, we tabulate and map IoT security problems against existing solutions found in the literature. More importantly, we discuss, how blockchain, which is the underlying technology for bitcoin, can be a key enabler to solve many IoT security problems. The paper also identifies open research problems and challenges for IoT security.

A parametric analysis of the state-of-the-art IoT security issues and solutions is described.

With the advent of smart homes, smart cities, and smart everything, the Internet of Things (IoT) has emerged as an area of incredible impact, potential, and growth, with Cisco Inc. predicting to have 50 billion connected devices by 2020. However, most of these IoT devices are easy to hack and compromise. Typically, these IoT devices are limited in compute, storage, and network capacity, and therefore they are more vulnerable to attacks than other endpoint devices such as smartphones, tablets, or computers.
