ABSTRACT
The Internet of Things (IoT) is a new perspective in which objects are connected via the Internet and have the ability to intelligently interact, understand and ex change data. As the number of IoT devices circulating in various sectors increases, the issue of data communication responsiveness and device security is growing. IoT device connectivity and security issues are more prevalent in devices that are always on the move and require regular real-time requests from various sensors. This makes them vulnerable to eavesdropping during the process of connecting to the IoT device’s server provider.
Based on these problems, a scheme is needed to increase responsiveness and reduce response time in the IoT authentication process by utilising the fog com puting scheme in integrating IoT microcontrollers with smartcontract blockchain NFT technology to authenticate so that connectivity is faster and more secure be tween IoT microcontrollers and fog nodes that are placed locally o
