摘要：Business organizations widely accepting cloud computing to handle their complex business process and increased business transactions. Organizations IT infrastructure and IT management had moved onto the cloud infrastructure and accessed through third party network. Cloud computing delivers on-demand services over the internet. Cloud service provider must ensure the security of the data and processes to the cloud users. Multitenancy being one of the key features of the public cloud. It is required to entrust security and privacy of the users outsourced valuable data. Several access control models have been proposed for cloud computing. Being highly dynamic cloud computing environment demands flexible, fine-grained, dynamic access control models. Business processes are expecting on time data for their analysis and client needs. Encryption based access control models proved better for cloud computing to hold outsourced data. We can prevent access to the encrypted data by hiding keys to decrypt the data. Cloud computing storage being remote to the user demands encryption-based access control models. We require access models with dynamic policies and with dynamic authorization. In this paper, we will be discussing the design, framework, and development of RA-HASBE access control model having dynamic authorization mechanism. We will explore the implementation and analysis of RA-HASBE access control model
