Abstract


People always believe that the IPv6network is safer than the IPv4because IPv6has huge network addresses. However, more and more researches show that IPv6is not unbreakable and it also faces serious threats of worms. The IPv4-IPv6dual-stack worm is a new worm which could spread in IPv4-IPv6hybrid networks rapidly using an intelligent scanning mechanism. Studies show that the worm is able to propagate much faster in IPv4-IPv6dual-stack network than that in the pure IPv4Internet. So, the worm is the potential threat from IPv4network to IPv6network transition.This thesis studies the propagation mechanism and propagation process of IPv4-IPv6dual-stack worm, analysis of the dual-stack worm propagation model and the WAW model. Based on this, the worm-anti-worm strategy is used to protect the vulnerable hosts from the attacks of the dual-stack malicious worms and a dual-stack worm containment model is proposed to describe the propagation of benign and malicious worms. After building model, we get the propagation curve of benign and malicious worms by numerical analysis.In the thesis, the simulation experiment on containment model is designed. Comparison of numerical analysis and simulation results shows the interaction of the two worms and verifies the effectiveness of the model. In addition, we conduct multiple sets of simulation experiments with different key parameters, and put forward several methods to improve the effect of benign worm though analysis of the simulation results.
