Cloud storage enables users to remotely store their data and enjoy the on-demand high quality cloud applications without the burden of local hardware and software services. Though the benefits are clear, such a service is also relinquishing user’s physical possession of their confidential data, which inevitably poses new security issues towards the correctness of the data in cloud storage. In order to solve this new problem and further achieve a secure and dependable cloud storage service, key management and key sharing plays the main role in the data sharing concept of cloud computing. Key Aggregate cryptosystem is a concept in which key is generated by means of various attributes of data in various cipher text classes and its associated keys. Key aggregate consist of various derivations of identity and attribute based classes of respective data owner of cloud. Irrespective of traditional cryptographic key generation and derivations, this technique possesses complicated, unique and vigorous cryptographic key aggregate cryptosystem which is optimal for secure cloud data and privacy preserving key generation process. cloud access level policy in infrastructure such as Public Private and hybrid Access level to enhance the data access mechanism in the data sharing cloud mechanism process. The data security algorithm such as Blowfish to AES as Blowfish algorithm results in higher security and faster execution when compared to AES (Advanced Encryption standard) and DES (Data Encryption Standard). Even though the algorithm has been undergoes to a number of cryptosystem analysis, the blowfish algorithm has never been failed. Proposed approach provides more security and efficient cryptographic scheme in which an effective derivation of secret key generation and key management for the outsourced Cloud data.
