Anonymous Communication Link Security Test Method

At present,the Internet is developing rapidly,the increasing threat o f information security,privacy protection has become increasingly important.Privacy protection means a lot,w hich anonymous communication is the Internet to protect user privacy is an important means,it can effectively defend the attacker's monitoring and traffic analysis attacks.But anonymous communication system is not absolutely safe,its widely used at the same time,related research and attack more and more.Anonymous communication system is the meaning of the data through the multi-node transmission and data encryption to hide the important information between the two sides of the communication,and in the process,if the attacker can get the entire link of communication,you can get both sides of the communication IP,Port and other basic informati on,and then get other important information,so anonymous communication system link security is very important.This paper investigates the development process of anonymous communicatio n system,the current research situation both here and abroad,and the threat and defense of anonymous communication system in link security.By studying the specific communication process of anonymous communication system and communication data,The encapsulation process in the communication process,based on the packet gro uping and data transmission,has developed two kinds of confrontational testing methods for link security.An anonymous communication system is built on the Internet,and on this basis,the adversarial test is carried out,that is,w hether it can detect the nodes before and after the node on the basis of some nodes,so as to obtain the complete link of the test node.The test results of the two test methods were analyzed by destructive and accurate analysis,the specific effects of the two test methods on t he anonymous communication system,and the identification of each node.
