摘要： 网络蠕虫的传播对互联网安全构成了严重的威胁，接种疫苗是蠕虫防治的一种有效手段。该文提出了一个基于Agent的网络蠕虫防御系统，通过Agent互相协作共同抵御网络蠕虫。Agent在网络中迁移，把疫苗安装到网络中的各个主机节点。通过对Agent的迁移机制和疫苗存储库结点的部署算法的研究，并应用到系统中，实现了疫苗分发路径的优化，缩短了疫苗的分发时间。

Abstract: Worm attacks are threatening today’s Internet security. Vaccination has become an effective means for combating Internet worm. This paper proposes an agent-oriented worm defense system by which the agents collaborate with each other to defend against Internet worms. Some agents travel in the network and distribute vaccine to every host. It researches the migration mechanism of agents and the deployment algorithm of vaccine repository nodes. By this way, vaccine distribution path is optimized and distributing time is shortened.

Key words: Internet worm, Agent, network security, vaccination
