A Risk-Aware Reputation Mechanism for Resource Sharing on Grids
Wei Feng Du, Guohua Cui, Wei Liu · 2009
Because of highly dynamics, openness and autonomy of grid, effective access control mechanism is required to guarantee secure resource sharing on it. To resolve such problem, reputation and risk are formalized based on cloud model theory in this paper firstly. Subsequently, risk-aware reputation inference, combination and evolvement algorithms are designed respectively. Simulation results show higher risk sensitiveness and effectiveness of our proposal.
