In recent days, the cloud data storage becomes a rising trend that promotes the secure remote data auditing.The existing works consider the problem secure and efficient public integrity auditing for shared dynamic data storage.But, it is not secure against the collusion of cloud data and it revokes the group of users during the user revocation in cloud system.Thus, this paper proposed a new public integrity auditing mechanism with the help of Message Authentication Code (MAC) generation and symmetric cryptographic techniques.The main intention of this paper is to design a secure and an efficient cloud data storage system to reduce the bandwidth and to improve the data integrity.The proposed system supports an effective user revocation and public checking processes.Moreover, it supports some properties such as, confidentiality, countability, efficiency and traceability for secure data storage.The experimental results are analyzed and evaluated in terms of computation time, block size, key size, number of rounds and cycles per block.
