摘　　要：内容中心网络是下一代互联网体系的研究热点,但其安全性研究国内外均尚处于起步阶段。文中针对内容中心网络如何防御Locality-Disruption和False-Locality两类典型缓存污染攻击的问题,提出了两种缓存污染防御策略:基于稳态内容存储分布的CPDP-SCCD与基于内容请求分布的CPDP-CRD,对比分析了基于内容请求分布以及基于稳态内容存储分布的防御有效性。仿真结果表明:相比较基于内容请求分布类策略仅对于Locality-Disruption攻击有防御效果,CPDP-SCCD的综合性能更佳,可以同时有效控制Locality-Disruption与False-Locality两类攻击。Today, content centric networking （CCN） is a research hotspot of future Interact architecture, but the research on CCN security is still at the preliminary stage. Aiming at how to defend two typical cache pollution attacks-Locality-Disruption and False-Locality, this paper proposes two defense strategies： CPDP-SCCD and CPDP-CRD. The former is based on the stationary distribution of cached contents and the latter is based on content request distribution. Furthermore, the contrastive analysis on the effective- ness for two different defense strategies is given. Simulation results show that the strategy based on con- tent request distribution only has an effect on Locality-Disruption attack, but CPDP-SCCD can effectively restrain Locality-Disruption and False-Locality attacks simultaneously, thus it has better comprehensive performances.
