Towards A Secure Distribute Storage System

Today's storage paradigm is shifting from the closed and managed mode to be more open and dynamic. Network storage system can be made up of a group of loosely coupled and heterogeneous storage resources. But this openness exposes the data directly to the unknown or unmanaged storage servers. Thus it is more necessary and challenging in these storage systems to ensure data security. In this paper we propose a new secure network storage system architecture which adds a layer of management nodes between users and storage nodes. This architecture is able to provide reliable and secure data storage services while storage servers are suffering from various types of intrusion. The architecture greatly reduces the scope of trust from a large scale of storage nodes to a few management nodes, and provides a flexible access control mechanism, which ensures the data privacy, integrity and availability while preserves the flexibility, efficiency and scalability.
