Trust model is proposed in grid entity transcation because of dynamics and uncertainly of campus grid. In this paper, a trust model in autonomous domain is presented. Researching on trust value calculating and updating in domain discuss the trust value calculating model in campus grid domain, This paper proposes the algorithms about trust value calculating and updating in grid entity.

Research on trust model in autonomous domain of campus grid

Grid computing is a new style of distributed computing technology.Grid,which can absorb various computing resources and translate them into convenient and reliable computer power,is a compositive environment of computing and resource.The characteristics and architecture of grid are put forward,then a difference between grid and traditional distributed computing is proposed.Finally analyze pivotal technologies in building campus grid environment.Building campus grid environment is an important work in grid gaining ground.In building campus grid system,there are many technologies to be studied and took shape,for example security mechanism,resource management,task management,communications technology.
