In cloud storage systems, users can upload their data along with associated tags (authentication information) to cloud storage servers. To ensure the availability and integrity of the outsourced data, provable data possession (PDP) schemes convince verifiers (users or third parties) that the outsourced data stored in the cloud storage server is correct and unchanged. Recently, several PDP schemes...
For validating the data integrity in the cloud storage, several provable data possession (PDP) schemes have been proposed to concern with this issue. However, these schemes are either inefficient or insecure under some circumstances. In 2015, Ren et al. Proposed an efficient mutual verifiable PDP (MV-PDP) scheme with stateless property. In this article, we will show that their scheme cannot provide...
It has become a challenge to organize and process large scale multi-dimensional data. In this paper, we present R-HBase, a multi-dimensional indexing framework for cloud computing environment. The R-HBase framework consists of storage layer and index layer. The storage layer supports high throughput and the index layer answers query efficiently. R-HBase is evaluated with synthetic data. R-HBase can...
