  Cloud computing has been envisioned as the next generation architecture of IT
Enterprise. Using Cloud Storage,users can remotely store their data and enjoy
the on demand high quality applications and services from a shared pool of
configurable computing resources, without the burden local copy data storage
and maintenance. It moves the application of software data stored to the
centralized large data centers, where the management of the data stored
services may not be completely trusted. There are many new security challenges
and the problems taken into account for ensuring the integrity of data storage
in Cloud Computing. In particular, we consider the task of allowing a third
party auditor (TPA) to perform verifies the integrity of the dynamic data
stored in the cloud.
