Secure Authentication in Wireless Sensor Networks Using Blockchain Technology

Abstract

A wireless sensor network (WSN) is capable of monitoring, fetching, and transmitting data from one place to another in any condition. The internet of things (IoT) network, a type of WSN, and its protection have always been a big problem. There are lots of risks related to security in this network. Authentication of node identity is an essential security concern. Conventional security algorithms for IoT rely on trustworthy third parties. They might fail at a single stage point. Therefore, in this chapter, the model is proposed as the solution to the security concerns by blockchain concepts. So, in this chapter, a trust model is introduced based on blockchain for WSN for communicating with several nodes without having any risks related to security.
