Blockchain Based Single Sign-On Support for IoT Environments

IoT technologies, According to the Gartner report for 2015, include billions of dollars in investment and a high academic research area. The issue of security in IoT systems comes to the fore and important studies are carried out on the problems encountered. In this study, a new blockchain approach to user access management problem for IOT environments is proposed in the light of current literature in the literature, considering the application-level security vulnerabilities in IOT devices. The single sign-on method discussed in access management is an important technique that helps to coordinate different authentication mechanisms, user logon, and user account management functions within an organization at both the point of availability and security. The blockchain offers an advanced security for systems with its encrypted and distributed data structure. In this context, blockchain technology for user access management in IoT devices and keycloak which provides a single sign-on infrastructure for authentication and session management on devices, are used.
