A Study on Anonymous Communication

While the popularity of computer technology has brought great convenience, it has also brought great security risks. People pay more and more attention to the security of information transmission, and anonymous communication has also made great progress. Anonymous communication refers to taking certain measures to conceal the communication relationship in the communication stream, making it difficult for eavesdroppers to obtain or infer the relationship and content of both parties in the communication. The purpose of anonymous communication is to conceal the identities or communication relationships between the two communicating parties and protect the personal communication privacy of network users. This paper studies the current anonymous communication technology, summarizes the working principle of anonymous communication systems, compares the advantages and disadvantages of existing anonymous communication systems, and proposes an anonymous communication mechanism based on P2P network and DNS hidden tunnels.
