基于IPv6网络环境分析了网络蠕虫的扫描策略,构建了一种新型网络蠕虫--DNSWorm-V6,该蠕虫应用两层不同的扫描策略,即在本地应用子网内扫描策略,在子网间应用DNS扫描策略.由此两层扫描策略,提出一种双层蠕虫传播模型TLM.仿真实验结果表明,DNSWorm-V6是一种可以在IPv6网络中大范围快速传播的蠕虫.可以预测IPv6网络中新型蠕虫可能带来的威胁.

In IPv6 network environment, the scanning strategy of Internet worm was analyzed.A new type of worm, DNSWorm-V6 was built.The worm applies two different layers scanning strategy.It means that the worm applies subnet scanning strategy in local subnet and applies DNS scanning strategy in inter-subnet Based on the two layers scanning strategy,a Two-Level worm propagation model, TLM was presented.The results of simulation experiment show that DNSWorm-V6 is a worm that can propagate fastly in the large-scale in IPv6 network,at the same time we can predict the threat probably posed by the new worm in IPv6 network.
