Research on trust-based dynamic role access control model

Abstract

In the grid environment, the peer's behavior is uncertainty and dynamic which make the traditional Role-Based Access Control Model(RBAC) cannot effectively identify various malicious behaviors of peer. We introduce trust mechanism into RBAC Model, and dynamically grant access authority through value of peer's general trust. Experiments show the feasibility and benefit of our approach. © 2011 Springer-Verlag Berlin Heidelberg.
