Along with the development and application of Cloud Computing in recent years, Cloud Storage, as the module which provides data storage service in the Cloud Computing architecture, has become the kernel component of Cloud Computing. More and more services choose Cloud Storage to manage data. At present, the major obstacle of the Cloud Storage application is the security problems, and the common secure system use data encryption to protect data. But the data encryption result in that the authentication of data become a big challenge. In most current secure system, Merkle Tree was widely used, however, because write operation need to update Merkle Tree and multiple users modify a single Merkle Tree at the same time should lead to consistency problem. So all the secure systems do not support concurrent write yet, and it has became a big obstacle for secure Cloud Storage which should support high performance storage services. In this paper, we present the design, implementation, and evaluation of PsFS, a high-throughput parallel file for secure Cloud Storage base on a new concurrent write mechanism, which use Multi-Merkle Trees to authenticate the integrity of the data.
