Abstract

The use of cloud computing has increased rapidly in many organizations. Cloud computing provides many benefits in terms of low cost and accessibility of data. Cloud Computing has been envisioned as the next-generation architecture of IT Enterprise. It moves the application software and databases to the centralized large data centers, where the management of the data and services may not be fully trustworthy. The major advantage with this technology is it is cost efficient. But there follows a key disadvantage associated with it, the disadvantage with it is the security issues related to the data stored on clouds. We have first identified the potential security problems and the difficulties with fully extension of data dynamics in the cloud and service availability. While prior works ensure remote data integrity, they lack public verifiability and data availability. Hence the aim here is to ensure data integrity with public verifiability and availability. We have constructed an elegant verification with access rights scheme for seamless integration of these two salient features in our protocol design. This paper in particular tries to achieve public verifiability by manipulating the classic Merkle Hash Tree and moving towards multi clouds or in other words inter-clouds which has emerged recently. We have tried to assure data availability by adopting DepSky System model for multi-clouds.
