Cloud computing is an Internet based computing. It provides the services to the organizations like storage, applications and servers. In cloud storage User can store their data remotely without maintaining local copy of data. So the integrity verification and time delay consumption of the data is major problem in cloud storage. We ensure the data not tampered with other because cloud provider is not completely trusted. Integrity Verification and time delay consumption can be managed by without TPA by using AES and RC6 algorithm.
