Cloud computing technology is enabling IT to do more with the infrastructure that already exists, as well as adding new ways to expand capacity quickly and economically by using external cloud computing resources. This technology is enabling IT managers to treat infrastructure as a common substrate on which they can provide services to users faster, in a much more flexible way and in cost-effective way -without having to re-design or add to the underlying infrastructure. Given the benefits of cloud computing, its broad appeal is not surprising. However, this new approach does raise some concerns. Chief among them is securing stored data in the cloud. In this paper, we focus on cloud data storage security, which has always been an important aspect of quality of service. To ensure the correctness of users' data in the cloud, we propose a method by utilizing the homomorphic token with distributed verification of erasure-coded data. Our scheme achieves the integration of storage correctness insurance and data error localization, i.e., the identification of misbehaving server(s).
