P2P技术在僵尸网络中的应用研究

与传统集中式僵尸网络相比，P2P僵尸网络鲁棒性更好、拓扑结构更复杂，因此更难防御。针对上述情况，将P2P网络按拓扑结构分为4类，即中心化拓扑、全分布式非结构化拓扑、全分布式结构化拓扑和半分布式拓扑。对4类P2P技术从流量、消息传播速度和网络鲁棒性3个方面进行分析比较和实验验证，并指出以半分布式结构为代表的新型P2P网络具有较好的综合性能，是未来僵尸网络的发展方向之一。

Application Research of P2P Technology in Botnets

Compared with traditional centralized Botnets,P2P Botnets have better robustness and more complex topology,so that it is very difficult for defenders to confront P2P Botnets.This paper divides P2P network topology into four types: centralized topology,distributed unstructured topology,distributed architecture topology and semi-distributed topology,and studies these four types of P2P technology from the communication flow,the speed of traffic information dissemination and network robustness through analysis and experimental verification,and points out that the semi-distributed Botnet has better overall performance to be one of the future direction of development of Botnets.
