Apply Blockchain Technology for Security of IoT Devices

Abstract

The world is only beginning to see the value and potential impact of the internet of things (IoT). Until recently, access to the internet was bounded via desktop, tablet, or smartphone. With the (IoT), practically all devices and objects can be connected to the internet and monitored remotely. IoT devices simplify our lives and make organizations more efficient; however, there are still challenges to address, particularly in the security context. As we continue to embed these connected objects and a wider variety of wireless devices, it is mandatory to provide confidence in this vast incoming information source. Blockchain has emerged as a disruptive technology that will transform the way we store, share information, and impose restrictions to know the authentications. The data distribution and robust level of encryption will remove the need for trust among the involved parties and add another security layer for IoT data. IoT devices generate too much data using sensors and stored, processed, accessed the same using cloud computing and achieve security some extend using big-data. Big-data security mechanism is not sufficient to meet the security requirements of IoT devices. We have proposed the Blockchain encryption mechanism using different layers architecture for the IoT devices to achieve the desired security level. In this paper, we have focused on how Blockchain could possibly improve IoT security. We also survey the most relevant work to investigate challenges associate with IoT Blockchain convergence. This proposed mechanism will achieve the security mechanism in IoT devices some extend.
