Sharing encrypted data with different users via public cloud storage is an important research issue. This paper proposed the concept of Data Protection with Deduplication in Cloud Computing. In this model, the input plain text is placed into a block-128 in a specific manner, and key is calculated. By using this key, the plain text is transformed into intermediate cipher text. In the initial stage the scope of the project will be to provide Internet access through limited number of users and provide centralized management through a server. In addition, the authentication process in our scheme solves the Deduplication problem of data sharing. Data owner can extract a key which includes cipher texts indices, delegates identity and expiration date of the key. The cloud server is obtains the identity of download-applicant from the key with public parameter and then controls download right. On this paper proves that the authentication key cannot be fudged and the message in this key can’t denied. In order achieve efficient and secure data sharing in dynamic cloud storage, the method should be proposed stable in expense, and should be leakage-resilient. Our scheme can satisfy both requirements.
