针对当前网络架构安全的问题,以内容中心网络(content-centricn etworking,CCN)为例对NDN的安全机制进行研究。分析NDN保护并信任内容本身的安全方式,引出通过减少内容到用户间的跳数,可以有效避免中间系统对数据的破坏的理念,并结合现有的基于NDN架构的应用ACT、VoCCN和ANDaNA,分析NDN安全机制在真实网络下的应用情况,指出现有NDN安全机制存在的漏洞。该分析结果可为今后研究海量数据下的信息过滤问题提供参考。
Aim at security problem of network frame, take content-centric networking (CCN) as example to research the NDN security mechanism. Analyze the NDN safety way which on the protection and to trust the content itself. Bring an idea that by reducing the hops between users, it can effectively avoid data to be broken in the intermediate system. Through the existing application ACT, VoCCN and ANDaNA based on NDN framework to analyze the actual application state of NDN security mechanism in real network, point out the existing NDN security mechanism's holes. The analysis results can provide on information filtering under mass data research with reference.
