摘要
针对内容中心网络(CCN)中的缓存污染攻击问题,在分析总结内容中心网络中缓存污染攻击特征的基础上,通过构建遭受攻击时节点的缓存状态模型,对污染内容在节点的驻留概率以及各类请求的命中率进行计算,而后通过改变模型参数对不同特征的攻击行为进行模拟,按照攻击强度以及污染内容的数量将缓存污染攻击重新划分为4种类型,并对每类攻击进行分析。最终的仿真结果表明模型以及分类方式是合理的。
Content Centric Networking （CCN） is an emerging paradigm to replace IP-based Inter- net. In CCN, nodes are assumed to have a local cache to satisfy incoming requests, which can be subject to a new type of attack, namely cache pollution attack. Based on the summaries and analysis of existing cache pollution attacks in CCN, the state model of cache nodes which is under attack was built to solve the reside probability of pollution contents and calculate the hit ratio of interest pack- ets. Using this model, different characteristics of cache pollution attacks were analyzed. Then, cache pollution attacks were classified into four types and each was explained in detail. Simulation results show that the model and the classification method of cache pollution attack in this article are quite reasonable.
