The authors propose the secure data storage in clouds for a new decentralized access. The cloud verifies the authenticity of the series without knowing the user's identity in the proposed scheme. Their feature is that only valid users can able to decrypt the stored information. It prevents from the replay attack. This paper supports creation, modification and reading the data stored in the cloud and also provide the decentralized authentication and robust. It can be comparable to centralized schemes for the communication of data, computation of data and storage of data.
