Blockchain-Based Identity Management for Secure Access Control in Cloud Environments
Abstract
Identity and Access Management (IAM) is crucial for ensuring secure access to cloud resources. Traditional IAM systems are vulnerable to credential theft, privilege escalation, and insider attacks. This paper proposes a blockchain-based identity management framework that leverages decentralized ledger technology to enhance security and transparency. The proposed framework uses smart contracts to automate identity verification, role-based access control (RBAC), and multi-factor authentication. Performance analysis demonstrates that the blockchain-based IAM system reduces the risk of unauthorized access and enhances accountability through immutable transaction records. The study highlights the benefits of decentralized identity management in improving security, reducing single points of failure, and increasing trust in cloud-based systems.
