Cloud depository is one of the customary supplications of the cloud computing system, which offers on-demand offloading services for both individuals and institutions. Although utilizes do not have full faith in the cloud service providers (CSPs) within that, it is hard to decide either the CSPs meet their licit expectations for data security or not. Thence, it is evaluative to come up with productive auditing techniques to boost owners’ trust and reliance in cloud storage. In this paper, we are presenting a scheme of auditing for assured cloud storage based on a 2-dimensional data structure called a dynamic hash table (DHT), used to record the data information for public auditing. This scheme emigrates the approved information from the CSP to the TPA and thereby a remarkable reduction in the computational cost and communication overhead. Also, the deduplication technology is utilized to lower the capacity and bandwidth prerequisites of the utilities by removing repetitious informati zon and stockpiles, only an original replica of them. We enhance our design encourages privacy preservation by homomorphism authenticator constructed on the public key, and attend batch auditing by aggregate BLS signature technique. Experimental results indicate that our mechanism achieves secure deduplication and tag generation improvements.
