中文摘要：

通过分析节点感染交互的两种特征,将节点划分为敏感与非敏感节点,构建了非对称的计算机病毒传播模型。利用该模型仿真研究病毒的传播及免疫方法,研究发现敏感节点对病毒传播起主要作用,节点的免疫措施应针对节点类别进行制定,选取恰当的免疫时间及免疫方案有助于抑制病毒的传播。仿真结论对于理解计算机网络病毒传播及制定有效免疫策略提供了重要参考。

英文摘要：

Infection interactive features of nodes are analyzed, and the nodes are divided into sensitive and non-sensitive ones. An asymmetric computer virus propagation model is built. The model is then simulated to study virus propagation and methods of immunization. Our study shows that, sensitive nodes play a leading role in virus propagation. Immunization measures of nodes could be estabfished according to node types. Proper lime and methods of immunization would help to control the virus spread. Our simulation provides important reference for understanding computer virus propagation and establishing effective immunization strategies.
