摘　　要：为了深入分析影响对待(P2P)僵尸网络传播的因素,从动力学的角度刻画了P2P僵尸网络的形成过程。首先,根据P2P僵尸网络形成的过程建立了一个微分方程模型。该模型考虑了免疫措施对计算机恶意软件传播的影响;同时,通过分析模型平衡点的稳定性条件导出了消除P2P僵尸网络的有效免疫率;最后,通过数值模拟得出了有效免疫区域,随机仿真验证了有效免疫区域的正确性。结果表明,合理的免疫措施可以有效预防僵尸网络的爆发。For deeply analyzing the factors that affect the prevalence of P2P botnets, the formation of a Peer-to-Peer （P2P） botnet was portrayed from dynamic perspective. Firstly, the differential equation model was formulated according to the formation of P2P botnets, which considered the effect of immunization on computer malware propagation. Furthermore, effective immune ratio of eliminating P2P botnets was calculated by analyzing steady condition of equilibrium in the model. Finally, the effective immune region was obtained and verified by deterministic simulation and stochastic simulation, respectively. The results show that the outbreak of P2P botnets can be effectively prevented by reasonable immune measures.
