Blockchain Based Security Framework for IoT Implementations

Abstract

The buss words blockchain and internet of things has been floating around the tech world for quite a while. IoT has already proved that it can have a significant impact on our daily life. A significant amount of data is collected and transmitted through the internet from various devices across the globe. IoT consists of heterogeneous devices communicating over a wide range of networks transmitting lots of critical and non-critical data, which raises concern about the security of such collected data from the users and the ownership of the data. This paper introduces a security framework for the internet of things implementation in a confined environment, such as smart city, power grid or metro rail systems, etc. The framework ensures the secure communication and authentication of the data across such diversified networks and devices. The framework is built upon the underlying mechanism of blockchain technology combined with the use of secure hashing algorithm.
