Enabling Public Auditability and Data Dynamics for checking data integrity in Cloud Computing

The major factor in development limitations of cloud computing is an issue about the data security. The data security protects data versus deviation and unauthorized access. The creation acceptable level of the data security requires an attention of the principles of data security. The most important principle is integrity. integrity ensures authenticity and information accuracy. The data security problems in all types of cloud computing services is an issue, and requires to use of security principles and technical mechanisms safety, in order to solve user’s concerns. So far, several methods have been proposed to control the security of cloud computing. But data security in the cloud computing is still a bottleneck. In this study, DICM method is proposed for improving of the data security in cloud computing. The most important features of the proposed method are public auditability, and supporting of dynamic data operations. The proposed method is implemented by using of the simulator CloudSim. Analyzing of the evaluation parameters derived from results of simulation experiments shows that, the process of check integrity has the lowest cost of communication in comparison with other designs, the consumption of network bandwidth is minimizing.
