With the rapid development of cloud storage, more and more users choose to use cloud storage to store their own data. The biggest feature of cloud storage is that storage is a service that allows users to upload their data to the cloud through the public API. But because the user loses the absolute control to the data, some data security hidden trouble also produces. In order to eliminate the hidden danger and to improve the service quality of the system as far as possible while guaranteeing the security, in recent years, the domestic and foreign institutions have done a lot of research, thus opening a research direction of cloud storage--secure cloud storage System. This paper first introduces the security requirements of cloud storage system, then the paper expounds the research status of the secure cloud storage system, and sums up the present situation and deficiencies of some key technologies in the existing secure cloud storage system, including key distribution and management, attribute based encryption mechanism, search mechanism based on data cipher and deletion redundancy mechanism, The identification and recovery of data and the credible deletion of data, and finally the future research direction of secure cloud storage system is pointed out.
