In Cloud computing, Data sharing is the important functionality. Secure distributed data storage was developed to reduce the burden of data owner from managing numerous files, by transferring the files from data owner to proxy servers. Proxy servers can convert encrypted files for the owner to encrypted files for the receiver withoutthe necessity of knowing the content of the original files. In practice, the original files will be removed by the owner for the sake of space efficiency. Therefore, there is no guarantee that the outsourced files are not accessed by the unauthorized users and not modified by proxy servers is an important problem that has been considered. Hence, the issues on confidentiality and integrity of the outsourced data must be addressed carefully. In this paper, there are two Identity-Based Secure Distributed Data Storage (IBSDDS) schemes. The properties of IBSDDS schemes are as follows: The file owner can decide the access permission independently without the help of the private key generator; for one query, a receiver can only access one file, instead of all files of the owner. These schemes are secure against the collusion attacks, namely even if the receiver can compromise the proxy server, but cannot obtain the owner’s secret key. Though the first scheme is only secure against the chosen plaintext attacks (CPA), the second scheme is secure against the chosen cipher text attacks (CCA). To the best of our knowledge, it is the firstscheme where access permission is made by the owner for an exact file and collusion attacks can be protected.
