Secured Cloud Info Storage in Addition to Integrity Products and Services
S. Thirunavukkarasu, M. Masthan · 2014
Cloud computing is the next stage in evolution of the internet, which provides large amount of computing and storage to customers provisioned as a service over the internet. However the prevalent problem associated with cloud computing is the cloud security and the appropriate implementation of cloud over the network. In order to make easier rapid deployment and to provide security, publicly auditable cloud data storage is established to reduce energy and save money. For the first time we formalize and implement effective utilization of single software through cloud, which can be accessed by several other systems for online testing. We consider the task of including a third party auditor (TPA) for client-side verification of data integrity. In order to regain the assurances of cloud data integrity and availability and to enforce the quality of cloud storage for users, we propose highly efficient and flexible distributed storage verification scheme by improving the existing model by manipulating the AES algorithm. The store and retrieve processes are done by crypto graphical methods. Numerical studies are extensively performed about the proposed scheme and the analysis shows that current cloud needs an order of magnitude in performance improvement to be useful for various storage and data integrity purposes and indicate which improvements should be considered first to make sure the quality and demand for the cloud increases.
