Abstract: In IPv6 network environment,a new type of worm,WormIPv6 is presented in IPv6 network.Based on the analysis and research of the scanning strategy of WormIPv6,Simple Epidemic Model(SEM) and Kermack-Mckendrick model(KM) are established for simulating the propagation of WormIPv6.The results of simulation experiment show that IPv6 network can defend against random-scanning worms due to its huge address space.It is impossible that random-scanning worms propagate in IPv6 network and Internet worm will use other scanning strategy.

Key words: Internet Protocol Version 6(IPv6), Internet worm, worm scanning strategy, worm propagation model

摘要: 基于IPv6网络环境,构建了一种新型网络蠕虫—WormIPv6,对其扫描策略进行了分析研究,在此基础上分别建立SEM模型和KM模型,分别仿真WormIPv6的传播趋势。仿真实验结果表明,由于IPv6中巨大的地址空间,IPv6网络对于随机扫描蠕虫有天然的抵抗能力,在IPv6网络中,使用随机扫描策略的蠕虫根本无法传播,网络蠕虫会利用其他扫描策略。
