Achieving Decentralized and Dynamic SSO-Identity Access Management System for Multi-Application Outsourced in Cloud

The majority of Single Sign-On (SSO) access control systems in use today rely on traditional protocols that require additional identity providers and/or authentication methods. The increasing requirement to outsource system resources, like data and apps, to cloud platforms makes it impractical to deploy traditional SSO methodologies to provide efficient and granular access control for multi-user and multi-application settings. In this study, we provide D2-IAM, a block chain-based identity and access management (IAM) scheme, as a strong security measure for controlling SSO access to cloud resources. Essentially, smart contracts and blockchain technology are used in D2-IAM's access control processes, and every access transaction is meticulously documented for accountability. Our system's SSO authentication is based on the highest level of authentication and hashed-based token management. Because of the autonomous authentication management, there is less communication overhead when working with identity providers and third-party verification mechanisms for multi-system authentication. D2-IAM uses access policies that are specified, upheld, and represented for each client in the document database to give granular access to the authorization system.
