Using Blockchain Technology to Prevent Spoofing Attack in IoT Environment

Nowadays, we notice an increasing trend towards connected devices, this trend of connected devices instead of people is called Internet of Things (IoT). Most of these connected devices are wireless sensor and battery-driven which when they connected together, they compose Wireless Sensor Network (WSN). Current, WSN devices started to communicate through IP, which take ability to connect to internet, making WSN vulnerable against many attacks such as spoofing. This is a vital problem, since IoT devices often leak of protection due to its limitations. To the best of our knowledge, previous studies used public blockchain of protection IoT. This research presents the design, implementation, and evaluation of a new Blockchain model for IoT devices to protect them from spoofing attack. We build a model using blockchain, then employ IoT to build and test the model and simulate a real environment by Raspberry pi that using Raspbian OS. The proposed solution can protect IoT networks against variant types of spoofing attacks but not only can be applied to a variety of routing protocols. Our Experimental results of 100 experiments showed that our model was able to prevent a lot of spoofing attacks but time was increased by 42% with blockchain.
