Cloud computing is one of the fast growing area in the computer field. The cloud must be secure because it may have sensitive data. There are some traditional techniques available but these are not sufficient. To enhance the security of the cloud, the authors are proposing this scheme. In this paper, the data i.e. cloud is decentralized and can support the unsigned affirmation of data stored in cloud. In this cloud does not need to authenticate the user before storing the data but to decrypt the data one should authenticate by cloud. This scheme provides protection from reply attacks and may allow creating, modifying and reading the data from cloud.
