Cloud data owners prefer to outsource documents in an encrypted form for the privacy preserving. Therefore,it is essential to develop efficient and reliable cipher text search techniques. One challenge is that the relationship between documents will be normally concealed in the process of encryption, which will lead to significant search accuracy performance degradation. Also the volume of data centers has experienced a dramatic growth.

More and More Clients would like to store their data to public cloud servers(PVSs) along with the rapid development of cloud computing. New security problems have to be resolved in order to help more client process their data in public cloud. When the client is restricted to access PCS, he will delegate its proxy to process his data and upload them. On the other hand, remote data integrity checking is also an important security problem in public cloud storage. It makes the clients check whether their outsourced data are kept intact without downloading the whole data. From the security problems, we propose a novel proxy-oriented data uploading and remote data.
