摘要：Cloud computing is the emerging technology and also it requires strong security when dealing with public cloud data. Cloud access control is one of the security requirements. The basic security requirements for cloud storage are Authentication, authorization and Access control. There are various access control scheme available for cloud storage. To ensure security in cloud, access control is the important prerequisite. Access control gives the authorization rights to the individual users. Access control basically consists of access privileges based on the user requirement. Providing security to the cloud is the major concern. Access control is needed for most of the environment such as peer to peer, grid and cloud. Most of the cloud computing environment uses Role Based Access Control (RBAC). A Novel Role Based Access Control scheme is proposed to enhance the security requirement of cloud storage which is named as secure cross domain access control. Our proposed methodology maintains user's roles, permission and set of user attributes to produce attribute ID for each user. The proposed access control scheme consists of the RBAC, ABAC and DRBAC. This scheme minimizes the time constraints problem and Location constraints problem.
