Blockchain Mechanism Approach to Smothering of Denial of Service (DoS) Spikes: A Focus on Internet of Things (IoT) Technologies

Denial of Service (DOS) is a cybercrime that attempts to impede electronic consumers from accessing websites and online services by saturating a server with internet traffic. Cyber-spikers use a network of infected computers, tools like bots, and other machines they can access remotely. A decade ago, businesses and financial institutions lost approximately half a trillion dollars due to DOS spikes. DoS savages would triple in number before the closure of the year 2023 from about eight million less than five years ago. This study uses a blockchain-based decentralized authentication technique to guard against DoS attacks on the application layer of Internet of Things (IoT) technologies. This secured mechanism involves starting the communication process, developing the system, and suggesting an intelligent contract. Performance evaluation of the developed model was carried out by comparing the approaches’ temporal complexity. The recommended method was also used on two processors operating at two distinct speeds while utilizing the SolarWinds application, an online CPU stress test, and usage with a deduction that the second is preferred. An Intelligent contract for IoT machine usage is established to authorize the blockchain level.
