英文摘要： Under the background of virus spreading on the internet together with the existing theories, models, and methods of complex networks, a typical and universal dynamical model of information networks is established based on the hybridity and common statistical properties of the internet. Associated with the inhomogeneity of information networks, the viral spreading rules on the information networks are investigated to reveal the intrinsic relationships between parameters and topology structure of networks, and the spreading dynamics. A spreading dynamic model closely representing the real information networks will be built, and the relationships between network characters and the behaviors of virus spreading will be explicitly presented. Simultaneously, an effective security warning system and control algorithms for information networks will be designed.Comparing the tolerance and survivability of network with different topologyies toward viral random diffusion and intentional attack, the structure of the optimal networks will be designed to strengthen the stability and robustness of the network. This project will potentially provide theoretical analysis and methodological guidance for constructing an efficient, safe, and reliable information networks.
