An Approach to Minimize Computational and Communicational Overhead in Cloud Computing
Journal Title: International Journal of Computer Science & Engineering Technology - Year 2013, Vol 4, Issue 7
Abstract
Cloud computing has been envisioned as the next generation information technology architecture for enterprises. Cloud Computing moves the data on the cloud storage servers maintained by service providers, which deprive the user of their control of the physical possession of data, even though they are the owners of the data. This unique feature however has raised many new security challenges which have not been well understood. Efficient verification techniques are of significant importance for cloud customers to validate data integrity and availability are not applicable on the outsourced data without having a local copy of the data. Downloading all outsourced data in order to validate its integrity is impractical for the excessive I/O cost and the high communication overhead across the network Therefore efficient techniques are needed for this. In this paper, we introduce a framework and efficient constructions for dynamic provable data possession (DPDP), which extends the PDP model to support provable updates on the stored data.
