Threshold Control of Cache Pollution Attack Hit Rate Based on Content Dissipative Network

内容耗散网络的缓存污染攻击命中率高,难以检测。研究内容耗散网络缓存污染攻击的命中率与域间传输阈值的关系,对降低攻击命中率提供控制模型基础。提出一种基于零周期数相变自适应冗余信息抑制的内容耗散网络缓存污染攻击命中阈值分析模型,提高对缓存污染攻击的检测概率。设计内容耗散网络及缓存污染攻击系统模型,基于url内容块检测模型,得到缓存污染攻击命中判决准则,通过AS-BOOST使用并行的读写操作,进行零周期数相变自适应冗余信息抑制,得到优化阈值分布下的判决准则。实验结果表明,采用该算法能通过合理设定域间阈值,达到消除缓存污染攻击的效果,实现对内容耗散网络的安全控制。

The cache pollution attacks hit rate is high in content dissipative network, it is difficult to detect. The relation-ship between contents of dissipative network cache pollution attacks hit rate and inter domain transfer threshold is re-search, to reduce the hit rate to provide data base. A content dissipative network cache pollution attacks hit rate analysismodel is proposed based on zero cycle phase adaptive redundancy suppression, improve the detection probability of cachepollution attacks. The content dissipative network and cache pollution attack system model is designed. Based on URL con-tent block detection model, decision criterion of cache pollution attacks hit is obtained. The parallel read and write opera-tion is used by AS-BOOST, the redundant information is suppressed with zero cycle several phase adaptive method, thresh-old distribution rule is optimized. The experimental results show that, the algorithm can through reasonably set inter domainthreshold, eliminate the effect of cache pollution attacks, security control of the content of dissipative network is realized.
