Cloud computing is one of the emerging technology hotspots in the IT field after grid computing, distributed computing, parallel computing and utility computing. With the industry's general focus on cloud computing in three forms of service: Software as a service, platform as a service (Platform as a service, infrastructure as services (infrastructure as a, IaaS), Academia often does not deal with the specific forms of cloud computing, but focuses on the problems that arise when users outsource storage and computing tasks to the cloud server side. Among them, the data storage security is the foundation, is also the cloud computing application key. No doubt, as the owner of the data, even if all the data outsourced to the cloud server side, users should also have access to data and operational rights, and should be able to prevent malicious server to the data may be illegal operations. In the previous study of cryptography, the server was often considered to be completely trustworthy, while the situation of the server being semi trusted or untrustworthy was rarely noticed. And in the cloud, when the vast amount of valuable data stored on the server side, the server is half trusted or not trustworthy is precisely the most worthy of discussion. Therefore, this article from the maintenance of user rights and interests, from the protection of malicious servers to start, and strive to cloud computing under the theory of cryptography to make a certain contribution.
