以信息为中心网络的隐私保护研究

Privacy Protection in ICNs: A Survey

为了解决现有IP网络的问题,例如移动性和多路径问题,最近学术界提出了很多以信息为中心网络(ICN)的设计。在这些设计中,安全和隐私作为ICN网络设计的核心要素。现有的ICN设计缺乏必要的隐私保护机制,存在比较严重的安全问题。例如,ICN网络中的互联网服务商(ISP)可以任意缓存内容服务商(CP)所产生的数据,导致严重的信息泄露问题。本文总结和分析了ICN网络的隐私问题,并且对比总结了现有ICN网络的隐私保护方案的特点和有效性,最后探讨了ICN网络隐私保护研究需要进一步考虑的问题。

Several Information Centric Network （ICN） architectures have been proposed to solve several problems in the current IP- based Internet architecture such as mobility and multi - path forwarding. Among these schemes, security and privacy are considered as essential part in ICN. We analyze that existing ICN designs lack built- in privacy protection for content providers. For example, any router in an Intemet Service Provider （ISP） in ICN can cache any content, which may incur information leakage. In this paper, we an- alyze the privacy leakage problem in ICN, and compare the features of the existing ICN security solutions. Finally, we discuss the key issues in designing privacy protection mechanisms in ICNs.
