Federal Management of Virtual Organizations with Trust Evaluation

Dynamical and flexible resource aggregation tools are required in 21 century research. Scientists need to aggregate various digital equipments and cooperate with each other in different organizations through Virtual Organizations (VO) on the Internet in a flexible and dynamical way. In this cooperation and resource sharing process, trust evaluation is of great importance for flexible VO management. Traditional tools such as VOMS for grids are short in dynamism and trust evaluation. In this chapter, we propose a new scheme providing federal VO membership management based on trust evaluation, with which researchers can achieve appropriate trust relationships with each other and establish a particular VO dynamically to aggregate resources for their own purposes.
