Feng Chao · Chinese Journal of Computers · 2015
Cloud computing will become the main computing model in the future due to its advantages such as high resource utilization rate and high cost performance.How to securely store data including privacy data,however,becomes a huge impediment to its development.In this paper,the challenges,which cloud computing is confronted with,are listed first.The renting mode of cloud computing and its two key techniques,i.e.the virtualization and multi-tenant,are identified to result in these problems.And then the recent studies on cloud storage are reviewed in terms of cipher storage,security audit and cipher access control.The focuses involve in the framework and key techniques of cloud data storage,the problems and methods of security audit,and attribute-based access control methods as well as advantages and disadvantages of these techniques and methods.At last,the problems that the study of secure cloud storage is confronted with are identified,and further,the study trend of secure storage for cloud data is analyzed and predicted.
