摘　　要：针对目前对等计算(P2P)网络中越来越严重的病毒传播和感染问题,结合生物免疫系统的工作原理和P2P网络自身的特点,提出一种新的P2P网络主动免疫联防模型。该模型将Peer节点局部免疫系统和以反病毒中心节点(ACP)主导的整体免疫防御体系有机结合在一起,从而对通过网络传播的恶意代码、病毒进行有效的、主动的控制和防御。详细的描述了P2P网络主动免疫联防模型的组成和运作流程,分析了模型中需要解决的关键问题,重点研究了ACP对病毒报告的应答机制和相应策略,并构建实验系统对此研究结果予以验证。In this article ,a new active joint-defence immunity model of P2P（Peer-to-Peer） network is proposed, which is based on the principles of biologic immune system and the speciality of P2P network, in order to resolve the more and more serious problems of virus spreading and infection in P2P environment. The model is composed of Peers＇ local immune modules and ACP（ antivirus center peer）-leaded integrated immune system. In this way, it is effective to control and prevent those network viruses actively. In this article, we describe the components and the operating procedure of the model in detail, analyze the key problems existing in the model, and then lay a strong emphasis on study of the mechanism and selection policies of ACP response to virus reports from Peers. All these research results were tested in the experiment system.
