The security is an important aspect of quality of service in cloud. The cloud computing is of critical importance to assure users that their data are being correctly stored and maintained. Cloud computing inevitably poses new challenges in security threats. In this paper, the authors propose an effective and flexible distributed scheme with explicit dynamic data support to ensure the correctness of users' data in the cloud. This construction drastically reduces the communication and storage overhead as compared to the traditional replication-based file distribution techniques.
