| 摘要: |
| 随着即时通信(instant messaging)应用的日益广泛和用户数量的迅速增加,即时通信蠕虫(IM蠕虫)的发生频率也相应提高,传播范围变广以及危害程度加深,其正成为网络安全的重要威胁.首先综合论述IM蠕虫的研究概况;然后剖析IM蠕虫的基本定义、功能结构和工作机理以及IM蠕虫与其他网络蠕虫的区别与联系;讨论IM蠕虫的网络拓扑和传播模型;归纳目前防范IM蠕虫的最新技术;最后给出IM蠕虫研究的若干热点问题与展望. |

| Abstract: |
| With the abroad application of instant messaging and explosive growth of users in current years, IM worms have higher outbreak frequency, wider coverage and deeper hurt, which have been a serious threat to network security. In this paper, the concept and research situation of IM (instant messaging)worms, function component, execution mechanism and comparison with other worms are presented, then the network topology and propagation models are discussed, and finally the critical techniques of IM worm prevention are given. Some major problems and research trends in this area are also addressed. |
