The document proposes a hybrid authentication technique using blockchain authentication and artificial intelligence for user and device authentication in an integrated Internet of Things (IoT) environment. It discusses challenges with IoT security and reviews existing literature on blockchain and AI approaches for IoT authentication. The proposed technique aims to create a decentralized authentication system using a blockchain to store authentication records that are then used to train a neural network model. This trained model can authenticate new users and devices in the IoT network. The document outlines the objectives, methodology, and potential benefits of the proposed hybrid authentication approach for improving IoT security.
