| 摘 要： | 针对现有模型只用节点度来构建蠕虫网络的不足,同时考虑到影响实际网络演化的多种物理因素,引入了节点吸引力模型,并以此作为择优选择方式构建蠕虫网络,然后利用平均场理论和仿真对网络的演化机理进行研究.理论分析与仿真结果表明,蠕虫网络中的节点和新感染蠕虫主机建立的连接与节点度、网络带宽、主机性能等综合因素有着紧密的联系;所生成的蠕虫网络具有无标度网络的性质.

| Abstract: | The drawback of present models is that only the node degree is used to construct worm network.Taking into account the various physical factors influencing the real network evolution,a novel method is proposed to establish a worm network with preferential attachments by introducing a node attraction model.The network evolution mechanism is studied by using the mean-field theory and simulation.Theoretical calculation and computer simulation show that the connection between the nodes from the network and the newly infected host is related to the node degree,bandwidth,and host performance;the generated worm network has scale-free property. |

| Keywords: | worm network scale-free attraction random walker node degree distribution |
