An Approach for Secured Data Storage Using Cloud Computing

Cloud Computing has been envisioned as the next generation Architecture of IT venture. In contrast to conventional solutions, where the IT services are under proper physical, logical and personnel controls, Cloud Computing moves the Application software and databases to the large data centers, where the administration of the data and services may not be fully trustworthy. This unique aspect, however, poses many new security challenges which have not been well understood. In this paper, the authors focus on cloud data storage security, which has always been an important feature of quality of service. To ensure the correctness of users' data in the cloud, they suggest an effective and flexible dispersed design with two salient features, opposing to its predecessors.
