Improving dynamic data integrity verification in cloud computing

Cloud Computing has been envisioned as the next generation architecture of IT Enterprise. Clients release their burden of storing and maintaining the data locally by storing it over the cloud. As cloud provides many advantages, it also brings certain Security Challenges among them one of its Data Integrity Verification. Proposed approach uses RSA based storage security (RSASS) method uses public auditing of the remote data by improving existing RSA based signature generation. This public key cryptography technique is widely used for providing strong security. By using this RSASS method, the data storage correctness is assured and identification of misbehaving server with high probability is achieved. This method also supports dynamic operation on the data. The proposed Scheme supports dynamic operation using RSA signature and manipulating the classic Merkle Hash Tree construction. By using RSA Signature long query message and variable size block is also support. Extensive performance analysis show that Client Computation time for different size of file is increase at the average rate.
