Two-phased protocol for providing data confidentiality in cloud storage environments

Abstract

In expanding fields, such as cloud computing, one of the greatest concerns is related to data security. Transferring and storing data to a cloud computing infrastructure raises many issues related to data privacy and data integrity. In this context, we propose a protocol designed to provide data storage confidentiality in the cloud. The protocol implies splitting the data into small encrypted data chunks, dispersed into data storage volumes. It is a two phased protocol that handles separately the operations related to writing the data to the storage volumes and the operations of retrieving data from the corresponding volumes. © 2012 Springer-Verlag.
