Data storage security model for cloud computing

Abstract

Data security is one of the biggest concerns in adopting Cloud computing. In Cloud environment, users remotely store their data and relieve themselves from the hassle of local storage and maintenance. However, in this process, they lose control over their data. Existing approaches do not take all the facets into consideration viz. dynamic nature of Cloud, computation & communication overhead etc. In this paper, we propose a Data Storage Security Model to achieve storage correctness incorporating Cloud's dynamic nature while maintaining low computation and communication cost. © 2012 ICST Institute for Computer Science, Social Informatics and Telecommunications Engineering.
