Abstract: Worm validation experiments arc very important for worm research. Based on analysis of experiment environment construct method including mathematical modeling, simulation, emulation, test bed and hybrid modeling, an new worm model named virtual and real hybrid network worm emulation model was proposed. Because of combining simulation with emulation, the model balanced the fidelity and scalability very well.
