Cloud computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources
(e.g., network, servers, storage, applications and services) that can be rapidly provisioned and released with minimal management effort or
service provider interaction. During the last a few years, data security and integrity in cloud computing has emerged as a significantly important
research area that has attracted increasing attention from both industry and academia. The virtual environment of cloud computing allows users
to access computing power that exceeds what is contained within their own physical worlds. To enter this virtual environment, cloud users must
transfer data throughout the cloud. Typically, cloud users know neither the exact location of their data nor the other sources of the data
collectively stored with theirs. Consequently, several data security and integrity concerns have arisen, including key management, access control,
searchable encryption techniques, remote integrity checks and proof of ownership in the cloud.
