Abstract
Cloud computing brings the new technology for the IT environment. Cloud Computing maintains software and database in the centralized large data centers. Using cloud computing, we can share our resources and services from different location, in open environment. We may face some security problems, when we develop such cloud applications, as everything is stored in the large data centers. The services from these data centers cannot be trusted. In cloud environment security is the main challenge. So we have o ensure the integrity on data storage in cloud computing on behalf of the cloud client, we allow the TPA to verify the integrity of dynamic data stored in cloud. TPA eliminates the involvement of client to audit their data, which is stored in the cloud server. Data are stored in form of Merkle – Hash tree structure. TPA checks the integrity of the data with help of the bilinear aggregate Signature for multi user setting and carries multiple auditing tasks simultaneously. Our proposed scheme achieves batch auditing for multiple physical locations (multi server). If there occurs any server failure, using this schemes data to maintain integrity. No delegation for TPA to audit user’s data.
