Abstract


Since the Internet gained popularity, the network has become an important tool for information dissemination. Network security and privacy issues are becoming the focus of attention. The conventional encryption technology to protect the security of communications data only communication entity identity information private can not be effectively protected. Based on anonymous anonymous purchase in the voting, e-commerce and other network applications, especially in military areas of strong demand for user identity privacy, anti-network tracking technology attracted the widespread attention. Anti-network tracking technology to track the degree of difficulty by enhancing the network, the effective protection of user identity information and communication relations of both sides, to make up for the deficiencies of the traditional encryption technology. Recent studies suggest that, the The Present Anti network tracking technology mainly rely on re-routing forwarding mechanism the current rerouting forwarding mechanism, however, there are still some drawbacks: a single directory server communication forwarded based on a connection-oriented protocol, network status is easy to track; too large to deal with stress and the risk of attack; the information encryption key is fixed, vulnerable to replay attacks; forwarding information is scattered low level, to the network of long-term latent type track opportunity. For research focus to re-route, the network tracking technology and anti-network tracking technology research, the results of the following four aspects: 1. Connectionless reliable transmission technology. In other words, use UDP as a transport layer protocol, while this paper provides the reliability and security of data transmission at the application layer, not only retains a small UDP overhead, high efficiency, characteristics that can not be easily tracked, both similar to TCP reliable The advantages of transmission. First proposed and the distributed multi-tier network topology transponder technology. In this paper, the analysis of the previous re-routing mechanism system, pointed out that the purpose of forwarding routing, hierarchical management task and risk sharing the directory server. The technology to improve the forwarding network stability and scalability. 3. Proposed and implemented based on the multi-layer topology is not fully public library system security random key negotiation techniques. In this paper, the use of dynamic randomly generated asymmetric key information transfer key negotiation, on the one hand, to reduce the tedious work of key management, on the other hand enhanced resistance to replay attacks. 4 information packet forwarding technology. Packet transmission of large blocks of information, each group using a different routing path forwarding path between the grouping and the grouping does not have relevance to increase the degree of dispersion of the information forwarded.
