Blockchain-based identity authentication for Internet of Things systems
Anindya Nag, Md. Mehedi Hassan, Ayontika Das, Chetna Kaushal, Deepak S. Thakur · 2024
Systems for managing identities, which are frequently employed in practical contexts, are designed to make chores like maintaining credentials and carrying out authentication simpler. In recent years, initiatives have been made to provide blockchain-based identity management (IdM) tools that give users control over their own identities. Blockchain technology is a desirable solution for resolving IoT issues due to its distributed character. Identity authentication is an important element of service design that can effectively handle security issues with the IoT. Two of the most crucial security measures are authentication and authorization, both of which have digital identification as their foundation. Scalability, interoperability, mobility, security, and privacy should all be taken into consideration when developing IdM tools for the IoT. They then contrasted the initiative groups working on this technology by looking at blockchain sovereign identity solutions and IoT digital IdM solutions. In this chapter, the authors discuss Internet-wide digital identity issues and solutions. The authors examine how existing solutions meet IoT criteria including scalability, interoperability, mobility, security, and privacy. The authors also discuss about rising blockchain sovereign identity solutions and include IoT identity technologies. This chapter also discusses some real-life applications in which Blockchain-based Identity Authentication is utilized for IoT systems.
