Self-certifying Object-based Network Storage

The security of object-based network storage is the hot topic in current researching. There are many different keys in system for encrypting file, authentication and authorization. And there are file accessing and object storing in the same system. It brings difficult in management and ensuring the security of system. This paper present the self-certifying object network storage system, use multilayer strategy to manage different keys, design self-certifying pathname algorithm to manage authentication key and authenticate communication between client and metadata server or intelligent disk, design object-based cryptographic key management algorithm and create relation between key and file. This paper realizes the prototype of self-certifying object network storage and evaluates its performance, the result shows the prototype has good performance
