Abstract

The Internet of Things (IoT) is rapidly evolving into a revolutionary technology, connecting millions of devices and enabling a wide range of applications across industries. However, the tremendous growth of connected devices has raised concerns about the security and privacy of IoT networks. The deployment and distribution of IoT systems make them particularly vulnerable to cyberattacks, unauthorized data access and control, further emphasizing the need for security measures. Traditional security measures often fall short of solving these problems due to the scale, diversity, and resource limitations of IoT devices. With its key features such as decentralization, immutability, transparency, and cryptographic security, Blockchain technology holds promise for addressing these vulnerabilities in IoT. Using blockchain data distribution, data transmitted in IoT networks can be authenticated and secured, ensuring the integrity and confidentiality of users' sensitive information. Blockchain's consensus enables secure communication between IoT devices without the need for a central authority, reducing the points of failure and risk associated with middle management. Blockchain also provides strong identity and capacity management, ensuring that only authorized entities can interact with IoT devices and systems, thus strengthening privacy and preventing unauthorized access. Integration of blockchain technology with IoT environment to enhance their security and privacy. We investigate how blockchain can be used to protect data transmission, device authentication, and access control in the Internet of Things. We also examine the role of smart contracts in operating and maintaining security in IoT systems, such as ensuring that only authorized devices can access or update important information. Although the combination of blockchain and IoT has many advantages, it also brings some challenges that can affect the performance of IoT systems, such as scalability, scalability, and power consumption. This article also discusses these issues and presents solutions, including the use of lightweight algorithms and hybrid blockchain architectures. Performance and privacy benefits and improvements of using blockchain. Overall, research suggests that blockchain can increase the security and privacy of IoT networks, providing a solution and protection against the growing threats of IoT systems. The findings Highlight the potential of blockchain to revolutionize IoT security, enabling a safer, more efficient, and more reliable future for IoT applications across a wide range of industries.
