With the growth of cloud computing, you want to keep data, applications and resource safe with secure access control. Although the conventional system of identity access and management has been effective, these methods are susceptible to subsections such as sophisticated attacks that top down systems just cannot manage. This study investigates the use of block chain technology to increase authentication and authorization mechanisms in cloud services. In this paper, we proposed a new framework that uses unique features of blockchain (decentralized and immutable) to be integrated with cloud service architecture. The challenges it solves include data integrity, tamper resistance and transparent auditing. We analyze the proposed system mathematically and through performance measures, and compare with previous models that exist in literature. They show major advancements in both security and efficiency, demonstrating the transformative potential of blockchain technology for cloud-security.
