Abstract
With the rapid growth of cloud computing, secure access control for cloud storage has become a critical concern. Traditional access control mechanisms suffer from centralization, single points of failure, and trust issues. Blockchain technology, with its decentralized, immutable, and transparent nature, provides a promising solution to enhance cloud storage security by ensuring trustworthy access control. This paper proposes a blockchain-based access control framework that integrates smart contracts to manage user authentication and authorization securely. The framework aims to eliminate central authority dependence, reduce insider threats, and improve auditability. Performance evaluation through simulation shows the feasibility and efficiency of the proposed system, making it a viable candidate for secure cloud environments.
