Cloud computing is the one which offers infrastructure to the client on a pay as you use model by leveraging on the Internet technology. As this model depicts the electricity billing it is often termed as utility computing. As the use of cloud increases day by day the concerns of cloud also gets increased. There are number of data breaches that are happening day by day that affect the cloud growth. The major concern in adapting cloud is its security. In order to solve the security issues there are number of solutions proposed. This paper focuses on integrity assurance strategy for remote data. The technique proposed combines the encrypting mechanism along with the data integrity check mechanism. The analysis and simulation results show that our proposed auditing protocols are secure and it reduce the computation load and communication cost of the auditor.
