IoT Protection Against Cyber Threats Based on Blockchain and Access Control: A Comprehensive Review

The Internet of Things (IoT) has undeniably transformed the way we interact with the world around us. As a revolutionary technology, it seamlessly integrates into our daily routines, offering unparalleled convenience and efficiency. By embedding connectivity into everyday objects, IoT has made it possible for devices to communicate, making our lives significantly easier. This constant communication and data exchange occur everywhere, from our homes to workplaces, and even in public spaces. Unfortunately, whenever connections increase, the threat of attacks increases too. Therefore, there is a critical need for systems that provide robustness at the service level. In this paper, a basic interface to IoT devices’ security architecture along with blockchain is introduced to provide scalability and authentication. This survey differs from the majority of existing reviews in that it presents a more comprehensive review of emerging research to help researchers and readers understand the state-of-the-art IoT protection against cyber threats. Additionally, different types of IoT protection against cyber threats based on blockchain and access control techniques are described in this paper. The findings demonstrate that blockchain technology offers IoT devices security along with scalability
