NSM: A Security Mechanism for Object-Based Storage System

SOBSS is architecture of OBSS (object-based storage system) proposed from time, data trans-mission and security aspects by which performance of OBSS can be promoted effectively. In this paper, a security mechanism for OBSS called as NSM is proposed. The prominent feature of NSM is that a security model adopted in our architecture of SOBSS which is different from traditional security model. In NSM, clients request for only once, and then receive both data and credential necessary for next request process. The working principle of NSM is also discussed in our paper. NSM security mechanism in our architecture of SOBSS provides a scheme for simplifying security model in OBSS.
