Abstract Abstract: Cloud computing technology has been visualized as the next-generation architecture of IT venture. In contrast to traditional solutions, where the IT services are under proper physical, logical and personnel controls, Cloud Computing shifts the application software and databases to the large data centers, where the management of the data and services may not be fully reliable. This unique attribute, however, impose many new security challenges which have not been well understood. In this paper, we focus on security based on cloud data storage, which has always been an important aspect of quality of service. To ensure the correctness of user’s data in the cloud, we suggest an effective and flexible distributed scheme with two salient features, contrasting to its predecessors. We illustrate the use of a data partitioning method for implementing such security involving the roots of a polynomial in restricted field. The partitions are stored on randomly chosen servers on the network and they need to be retrieved to reconstruct the original data. Data reconstruction requires access to each server, the knowledge of the servers on which the partitions are stored and login password. Several variations of this scheme are described, which include the implicit storage of encryption keys rather than the data, and where a subset of the partitions may be brought together to reconstruct the data.
