With tremendous development of internet and cloud computing, StaaS (Storage as a Service) has been envisioned as the next generation architecture of IT enterprise. Enterprise and individual end users moves more and more important information to outsourced data centers, where the data may be misappropriated in the malicious model, Security and availability become the main concerns of cloud storage. This paper, to address these issues, presents architecture of a Security Cloud Storage Gateway, which provides implicit storage security to improve security and availability of Cloud Computing. We designed efficient data fragment algorithms based on IDA (Information Dispersal Algorithm), with which we can partition a file into a designated number of pieces and reform by part of the pieces efficiently. We also designed a Cloud Storage Application Programming Interface (CSAPI) for users, a method for accessing to and utilizing a multi-Cloud storage, ignoring difference, between various cloud servers. A prototype of the system is implemented using Java, then we present performance results of our implementation.
