Blockchain-Based IoT Device Authentication and Cost-Effective Key Management Framework

Abstract

IoT is seen as an exciting innovation that might start an entirely novel industrial revolution. A collection of Internet-connected devices. An unavoidable and pervasive framework is still an open problem in IoT research for embedded devices, neural networks, machine learning, and other widespread and universal systems. IoT systems rely on sensors and controllers. IoT uses millions of sensors to gather and share outside information with the public internet. Many applications analyze and evaluate diverse data collected from devices. Those compact devices for sensors have limited processing power. Security is crucial for precise data flow between verified users, which becomes more complicated in a network of IoT devices. IoT's decentralized architecture design faces security concerns include privacy, reliability, security, anonymity, and device-user trust. Due to limited resources in sensor devices, typical cryptographic techniques for identification and organizational management of keys are not suitable for IoT systems. Effective protection against electronic card theft, session data publication, external attack, passwords guessing, user sensing simulation, and anonymity for users is provided by the suggested technique. Because it meets all security criteria, the updated protocol offers better security. The simplest protocol that can survive all known attacks and provide the essential security is the suggested one. With a 99% success rate and superior performance across all measures, the findings show that the suggested blockchain technology IoT identification framework is the way to go.
