| 摘要: |
| 合理的蠕虫传播模型可以准确地描述蠕虫类恶意代码在网络中的传播行为，有助于在开展蠕虫防护、检测和抑制技术的研究时更深入地分析蠕虫的传播机制。通过引入和分析蠕虫的感染时间这个在经典的传染病模型研究中被忽略的重要因素，使用确定性建模分析方法推导得出SSI蠕虫传播模型，合理地反映网络中的脆弱性主机在蠕虫传播时可能的状态转换。模拟仿真表明，SSI模型可以相对准确地描述蠕虫类恶意代码在网络中的传播过程。 |

| Abstract: |
| Logical worm propagation model can characterize how the worm-like malicious code spreads in network exactly, which contributes the analysis of worm propagation mechanism in depth to engaging in the study of worm defense, detection and containment. The significance of infection time is often neglected in worm propagation models based on classic epidemic model. By introducing and analyzing infection time, a worm propagation model called SSI is derived using deterministic modeling methods. This model reflects the possible state-transition of vulnerable hosts during worm propagation, and results in a better understanding and modeling of the propagation of Internet worms. |
