Design and Implementation of cloud storage security system

The user identity information management and authentication, safety of the stored data in the cloud storage environment are the challenges of cloud security, all these have drawn attention of researchers in recent years. We made a security model of cloud storage: the model adopts many encryption methods to protect the user data and user identity information stored in the cloud storage management server, only authorized users can use cloud service. At last, we gave security analysis of the model, the result shows: the architecture is able to hide the characteristics of the data stored in the cloud server, certify and protect user identity information effectively.
