In Information Technology (IT) Enterprise, Cloud computing is a new era in computing technology, which envisioned on the next generation architecture. In this paper, the authors perform on both public auditability and data dynamics operations. Initially identifying security issues as well as complexities from the prior works and then constructing integration scheme with their two salient features in protocol design. By improving proof of storage modules by manipulating the classic Merkle Hash tree construction for block tag authentication to achieve efficient data dynamics. TPA can perform multiple auditing tasks through bilinear aggregate signature technique. The proposed schemes are more efficient and are provably secure during extensive security and performance analysis.
