The document discusses a semi-anonymous privilege control scheme called AnonyControl, which enhances data and identity privacy in cloud computing through attribute-based encryption. It addresses limitations in existing schemes by decentralizing authority to prevent identity leakage and managing access control more effectively. The proposed system is validated through security analysis and performance evaluation, highlighting its feasibility in securing cloud data.

Various schemes based on the attribute- based encryption have been proposed to secure the cloud storage. However, most work focuses on the data contents privacy and the access control, while less attention is paid to the privilege control and the identity privacy. In this paper, we present a semi anonymous privilege control scheme Anony Control to address not only the data privacy, but also the user identity privacy in existing access control schemes. Annoy Control decentralizes the central authority to limit the identity leakage and thus achieves semi anonymity. Besides, it also generalizes the file access control to the privilege control, by which privileges of all operations on the cloud data can be managed in a fine-grained manner. Subsequently, we present the Anony Control-F, which fully prevents the identity leakage and achieve the full anonymity. Our security analysis shows that both AnonyControl and AnonyControl-F are secure under the decisional bilinear Diffie–Hellman assumption, and our performance evaluation exhibits the feasibility of our schemes.

Few years later, Fuzzy Identity-Based Encryption is proposed, which is also known as Attribute- Based Encryption (ABE). In such encryption scheme, an identity is viewed as a set of descriptive attributes, and decryption is possible if a decrypter’s identity has some overlaps with the one specified in the cipher text. Soon after, more general tree-based ABE schemes, Key-Policy Attribute- Based Encryption (KP-ABE) and Cipher text-Policy Attribute-Based Encryption (CP- ABE), are presented to express more general condition than simple ‘overlap’. They are counterparts to each other in the sense that the decision of encryption policy (who can or cannot decrypt the message) is made by different parties. PROPOSED SYSTEM: A user can decrypt the ciphertext if and only if the access tree in his private key is satisfied by the attributes in the ciphertext. However, the encryption policy is described in the keys, so the encrypter does not have entire control over the encryption policy. He has to trust that the key generators issue keys with correct structures to correct users.
