Abstract
Cloud computing is a new paradigm of computing and is considered to be the next generation of information technology infrastructure for an enterprise. The distributed architecture of cloud data storage facilitates the customer to get benefits from the greater quality of storage and minimized the operating cost. This technology also brought numerous possible threats including data confidentiality, integrity and availability. A homomorphic based model of storage is proposed, which enable the customer and a third party auditor to perform the authentication of data stored on the cloud storage. This model performs the verification of huge file’s integrity and availability with less consumption of computation, storage and communication resources. The proposed model also supports public verifiability and dynamic data recovery.
