摘　　要：匿名网络旨在公开网络环境中保护用户通信隐私.自Chaum提出Mix网以来,相关研究在几十年中不断取得进展.如今,匿名网络已发展成以Mix网、DC网或PIR(private information retrieval)为基础,并结合多种设计要素,使之适用于各种应用场景和威胁模型.从匿名概念出发,介绍匿名网络领域的发展情况,分类阐述代表性研究工作及其设计选择,并系统地从匿名性、延迟和带宽开销等角度进行分析.Anonymous networks aim to protect the user’s communication privacy in open network environment.Since Chaum proposed Mix-net,related work has been progressing in decades.Nowadays,based on Mix-net,DC-net or PIR,many anonymous networks have been developed,for various application scenarios and threat models by integrating multiple design elements.Beginning from anonymity concepts,this paper introduces the overall development of anonymous network area.Representative works and their design choices are classified and articulated.The characteristics of anonymous networks are systematically analyzed from the perspectives of anonymity,latency,bandwidth overhead,etc.
