The distributed storage brings new vulnerabilities in creating a confidentiality and integrity of data are mostly achieved secure data storage and access facility. Particularly it is a using robust cryptograph schemes. challenge on top of insecure networks or unreliable storage However, such a security system is not robust enough to service providers. For example, in applications such as cloud protect the data in distributed storage applications at the computing where data storage is transparent to the owner. It is level of wide area networks. The recent progress of network even harder to protect the data stored in unreliable hosts. technology enables global-scale collaboration over More robust security scheme is desired to prevent adversaries heterogeneous networks under different authorities. For from obtaining sensitive information when the data is in their hands. Meanwhile, the performance gap between the execution instance, in the environment of peer-to-peer (P2P) file speed of security software and the amount of data to be sharing or the distributed storage in cloud computing processed is ever widening. A common solution to close the environment, it enables the concrete data storage to be even performance gap is through hardware implementation.
