摘要：Cloud computing provides various elastic and scalable IT services and users can reduce the huge capitalinvestments in their own IT infrastructure. Cloud computing falls into three broad categories such as software as aservice(Saas), infrastructure as a service(Iaas) and platform as a service(Paas). Third party auditor (TPA)allows toensure the correctness of data on behalf of the cloud client and to verify the integrity of the data stored in the cloud. Inthis paper, we provide one of the TPA algorithms such as Genchallenge for accuracy of an authorized auditing andverification. The results demonstrate that our scheme can offer an enhanced security and flexibility and alsosignificantly lower overhead for big data applications
