The current anti-virus systems are usually unable io respond to endless emerging malicious codes in time. To sohe this problem, this paper proposed and constructed a new malicious code united-defense network based on the Cloud-P2P computing model. The Cloud-P2P model integrated the cloud computing and the P2P computing systems together organically. Servers and user terminals in the malicious code united-defense network carry out their own duties, forming a high-security collaborative defense network against malicious cooes and obtaining the whole group immunity quickly. It also proposed two kinds of hierarchical network topology, C-DHT and D-DHT, which were based on the distributed hash table technology and suitable for the Cloud-P2P computing model. By the introduction of mobile agent technology, realized vaccine agent and patrol agent of the malicious code defense united-network. The malicious code united-defense network based on the Cloud-P2P computing model has ideal performances, such as the network load balance, the rapid response, the comprehensive defense and the good compatibility.%针对目前的反病毒系统在应对恶意代码时通常具有的滞后性,提出并构建了一种新颖的基于CloudP2P计算模型的恶意代码联合防御网络.Cloud-P2P计算模型将云计算与对等计算进行有机融合.恶意代码联合防御网络系统中的集群服务器与用户终端群体联合组成了一个高安全防御网,协同防御恶意代码,并快速产生群体免疫力.为了提高系统的性能表现,提出适用于Cloud-P2P融合计算环境的两种基于分布式哈希表的层次式网络结构C-DHT和D-DHT,并通过引入移动agent技术实现了恶意代码联合防御网络中的疫苗agent和巡警agent.基于Cloud-P2P计算模型的恶意代码联合防御网络具有负载均衡、反应快捷、防御全面和兼容性良好等性能表现.
