匿名通信综述

Survey of anonymous communication system

匿名通信系统是指建立在网络应用层之上,结合数据转发、内容加密、流量混淆等一系列技术,实现通信实体之间关联关系和通信内容对第三方隐藏的网络。在商业秘密传输、电子投票等使用场景中,保证用户的个人身份、行为不被网络窃听者所识别是重要的评价标准,匿名通信系统正是为了解决上述问题。匿名通信系统具有消息不可溯源、通信无法被第三方监测等特点。一方面,从数据隐蔽传输的角度,匿名通信系统能够增强系统的安全性,另一方面,由于匿名通信技术的滥用,非法构建的私有隐蔽服务花样繁多、层出不穷,给网络安全和社会安定带来了巨大危害,因此,对目前匿名通信系统和技术进行梳理,有助于了解匿名通信技术发展现状,进而更为合理地利用匿名通信技术,构建匿名通信系统,实现信息安全可靠传输。

Anonymous communication system refers to a network that is built on the network application layer and combines data forwarding,content encryption,traffic obfuscation and other technologies to realize the association between communication entities and the hidden content of the communication content from third parties.In the usage scenarios of business secret transmission and electronic voting,it is an important evaluation standard to ensure that the user′s personal identity and behavior are not recognized by eavesdroppers.Anonymous communication system is to solve the above problems.Anonymous communication system has the characteristics of untraceable message and communication cannot be monitored by a third party.On the one hand,from the perspective of hidden data transmission,anonymous communication systems can enhance the security of the system.On the other hand,due to the abuse of anonymous communication technology,illegally constructed private hidden services are numerous and endless,bringing network security and social stability.Sorting out the current anonymous communication systems and technologies is helpful to understand the development status of anonymous communication technologies,and then use anonymous communication technologies more reasonably to build anonymous communication systems to achieve safe and reliable transmission of information.
