Certain Investigation of Attacks in the Field of Internet of Things and Blockchain Technology

Abstract

The Internet of Things (IoT) and Blockchain Technology are more trending which are gaining popularity all over the world in recent times. IoT is a collection of several things that consists of sensors, actuators, and many other devices to perform identification and sensing by aggregation of data, interacting with other devices, and advanced processes in a real-time environment. However, at the same time, Blockchain comprises small blocks where each block can have an identity and hash value. Due to the huge sector of applications that can be achieved with IoT devices, threats and huge attacks can occur and make it an insecure state. Therefore, security and privacy have become an integral part of the internet of things. To the best of our knowledge, extensive studies are made on the security threats and different types of attacks in every layer of the Internet of Things. Moreover, the article focuses on the integration of blockchain technology with the Internet of Things (IoT) and the classification of Blockchain IoT (BIoT) attacks. The threat levels and the prevention techniques of attacks in IoT and Blockchain are incorporated respectively.
