Cloud storage systems have received extensive attention in recent years. Many individuals and business organizations are beginning to move their data to cloud environments. It becomes increasingly important to investigate secure file storage in cloud environments. In this paper, the authors present a secure distributed file distribution system in which the customers can directly choose appropriate design parameters and service providers. In their scheme, they use novel coding techniques that almost achieve the shannon information bound with very efficient coding and decoding process. Their evaluations show the correctness and efficiency of the coding scheme.
