摘要：Cloud computing can be defined as a new style of computing in which dynamically scalable and often virtualized resources are provided as services over the internet. With cloud computing technology, users u se a variety of devices, including PCs, laptops, smart phones, and PDAs to access programs, storage, and application-development platforms over the Internet, via services offered by cloud computing providers. Advantages of cloud computing technology include cost savings, high availability, and easy scalability. Cloud computing moves the application software and data bases to the large data centres, where administration of the data and services may not be fully trustworthy. This unique aspect, however, poses many new security challenges which have not been well understood. In this article, we focus on cloud storage security, which has always been important feature of quality of service. To ensure the correctness of users data in the cloud, we suggest an effective and flexible technique for managing the data storage technology in the secure way. By utilizing the PMAR homorphic encryption algorithm with dispersed authentication of erasure coded data , our scheme achieves the incorporation of storage correctness insurance and data error localization. i.e, the identification of misbehaving server.
