由于良性蠕虫可以主动地防御蠕虫的传播，因此引起了蠕虫研究领域专家的广泛关注．通过分析分而治之的混合型良性蠕虫的特点，将其划分为3个子类．在有延迟以及无延迟的情况下，推导了分而治之的混合型良性蠕虫的3个子类的数学传播模型，这些传播模型描述了分而治之的混合型良性蠕虫对抗蠕虫传播的过程．最后，仿真实验验证了传播模型，并且得到如下结论：在相同的感染条件下，复合的分而治之的混合型良性蠕虫抑制蠕虫传播的效果最好．

英文摘要：

Due to the active defense against the propagation of worms, benign worms are attracting wide attention in the field of worm research. The idea of benign worm is to transform a malicious worm into an anti-worm which spreads itself using the same mechanism as the original worm and immunizes a host. It allows for an active measure of malicious worms that can potentially be deployed with no additional infrastructure in place. A divide-and-rule-hybrid-benign worm is a pattern of hybrid benign worms. It can avoid the additional traffic generated by benign worms in the final stage of benign worms countering against worms. Divide-and-rule-hybrid-benign worms are classified into three subtypes by analyzing their characteristics. The propagation models of these three subtypes are derived under the circumstance of time delay and no time delay, and they depict the process of divide- and-rule-hybrid-benign worms countering against worms. Finally, the simulation validates the propagation models. And there is a conclusion that a composite divide-and-rule-hybrid-benign worm is the most effective approach for containing the propagation of worms under the same infectious condition. These models of benign worms lead to and speed of benign worms countering against the a better understanding and prediction of the scale propagation of worms.
