Survey of anonymous communication system

Abstract： 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.
