A Quantification-evaluating Trust Model Based on Grid Environment
Gu Tian · 2007
A grid computing system is composed of heterogeneous geographically-distrubuted computers and resources. And it is a high performance distribute environment. Users can share these resources pellucidly by the network. Because of the dynamics and uncertainty of grid environment, the collaboration of grid-entity is facing to a series of problem of security. So the trust issue of grid system becoms a hotspot in current study of grid. In this paper, we carve up the trust to identity-trust and behavior-trust, develop a new trust evaluating model to scale the relationg of the trust of grid entities, by which we can resolve security problems exist in grid environment more sciencely and effectively.
