对等网络中被动型蠕虫传播动力学建模与分析
Dynamical Modeling and Analysis of Passive Worms Propagation in P2P Networks
摘要
Abstract
Passive worms pose a threat to the security of the network. In this paper, considering network heterogeneity and the number of hops a search can reach, a novel dynamical model with recruitment rate and removal rate is proposed. The threshold, the basic reproduction number, is derived, which decides whether passive worms can spread. And the stabili-ties of the worm-free equilibrium and positive equilibrium are analyzed. Finally, the correctness of the theory is verified by numerical simulation, and the sensitivity of parameters is analyzed. The results show that if the basic reproduction number is greater than 1, the propagation speed of passive worms is accelerated with the increase of hop count, which increases the number of infected nodes. If the basic reproduction number is less than 1, the number of infected nodes decreases rapidly with the increase of hop count and passive worms are extinct eventually.关键词
