A Survey for Cloud Data Security

The security of cloud data is one of the most important factors to obstruct the development of cloud computing. Therefore, on the basis of proposed three-tiers cloud architecture that consists of physical resources layer, virtual component layer, and cloud service layer, this paper makes a detail survey on existing works that focus on the security of cloud data, which involves in cloud identify authentication, cloud access control, cloud data secure computing, virtualization, cloud data security storage, cloud data secure deletion, information flow control, cloud data secure auditing, cloud data privacy preserving, and cloud business continuity, respectively. Finally, research trends in the field of cloud data security are presented.
