Blockchain-powered defense

Abstract

The rapid development of the wireless sensor network (WSN) has been a major boost for business, industry, and society overall. The WSN, which consists of sensors and controllers, creates a complete environment of the WSN. This expansion has brought attention to flaws in the WSN architecture, especially due to the limited capacity of endpoint devices for computation, storage, and communication. The purpose of this chapter is to introduce a new concept about the ethereum blockchain. The objective is to identify and stop DDoS attacks on WSN platforms. The proposed framework not only addresses the pressing issue of cyberattacks but also addresses single points of failure, privacy concerns, and security threats that are frequently associated with WSN installations. The methodology involves two key components: a decentralized authentication platform. Instead of relying on conventional centralized systems, the proposal advocates for a decentralized platform. The application layer is where these platform operators provide a robust defense against DDoS attacks by authenticating and verifying sensor nodes thoroughly. The integration of blockchain technology is another crucial aspect of the approach, which involves tracking and prevention. These addresses are blacklisted by the system to prevent malicious devices from engaging with WSN, which safeguards against potential threats. A series of 100 experiments were conducted to empirically evaluate the effectiveness of the proposed system, with the main focus being on assessing the time efficiency of the authentication process. The system’s superiority is demonstrated by its performance, which involves fewer input/output operations than comparable approaches, resulting in significantly faster operation.
