Security enhancement and deduplication using zeus algorithm cloud

Abstract

Data deduplication method allows the cloud users to manipulate their cloud storage efficiently by avoiding the storage of certain repeated data having the same bandwidth. To ensure that the data is secure and confidential, and the data is stored by encrypting it. We can use various encryption types like the RSA, DES, and AES. Convergent encryption algorithm is commonly used to retrieve storage capacity and lower data upload throughput and yet poses two challenges. The first problem is that they might be unsafe for statistical attack. The other thing is that they have convergent key management problems. The current paper assists in the usage of key-sharing approach which is verified by the proof of ownership to rectify these problems. As in only the initial data uploader, the holder encrypts the data with a randomly selected convergent key and then disperses the key in the cloud, and the key can only be accessed by users who have the reported data. In the existing framework, we found out that in the convergent encryption, the key of any given data can be generated by anyone in a deterministic way. An attacker can generate a key from plaintext encrypt the plain text and check if the resulting cipher text is already existing or not. Thus to overcome the issues, we propose the much more secure Advanced Encryption Standard (AES) without the third-party administrator (TPA) and to reduce the burden of computational overhead on the admin. We have used the Zeus algorithm to stop the duplicate data string in the database. Zeus algorithm offers better deduplication process and work to reduce the computational overhead of the admin. Analysis shows that this design is more effective, and the proposed security model remains stable.
