Dynamic-Role Based Access Control Framework Across Multi-domains in Grid Environment

摘要

To improve system scalability and restrain cheat, which are two important aspects in resource sharing gird environment, a dynamic-role based access control framework is proposed in this paper. This framework imports trust model, proposes "conversion parameter" and dynamic-role to resolve the problems of access control across multi domains. Simulation results show that it can realize access control easily, prohibit malicious behavior of entities, and improve the scalability of the system. An implementation is also shown in this paper.
