Anonymous connection method of broadband radio IP network

Abstract

When mobile user logs on network to access host server, foreign agent FA and host agent HA are as network intermediate agent. Anonymity encapsulation method includes following step: selecting anonymous route in network layer, building anonymous connection, carrying out data encapsulation, as well as combination of polygenous network nested anonymous encapsulation and link encryption at intermediate router. Following measures are taken I the invention: encapsulating data packet transmitted, sharing anonymous channel, anonymous connection of distributed type route and anonymous encapsulation etc. The invention optimizes system capability of resisting interior attack to router and exterior attack to physical chain. Advantages are: favorable anonymity, transparency, expansibility and robustness.

Description

technical field [0001] The patent of the present invention belongs to the technical field of communication security, specifically a broadband wireless IP (Broadband Wireless IP, referred to as BWIP) network anonymity technology, which is suitable for future broadband wireless mobile IP (Internet Protocol, Internet Protocol) security, and can provide future mobile E-commerce, mobile e-government, etc. provide better anonymity technical guarantee. Background technique [0002] As people pay more and more attention to security and privacy on the Internet, in order to protect the privacy of users, some applications such as electronic voting (E-Voting), electronic banking (E-Banking), electronic commerce (E-Commerce) etc. will anonymity as a measure. In the application of broadband wireless IP network, the new value-added service of mobile device positioning turns the secret of mobile user's location into public information, and the user's privacy is greatly challenged. At the ...

Problems solved by technology

[0005] (1) Poor versatility. The onion routing technology achieves the anonymous effect through layer-by-layer encapsulation on the transport layer. This technology is applicable to a dedicated onion routing network and can only be realized through a dedicated onion router;

[0006] (2) low efficiency, because the onion routing technology adopts layer-by-layer encapsulation method, when there are more than 10 onion routers in the middle, the protocol efficiency of the system is lower than 30%;

[0007] (3) The robustness is poor. Since the onion routing system adopts the connection-oriented virtual circuit method between the sending and receiving parties, and adopts strict source routing method for encapsulation, once a fault occurs anywhere in the virtual circuit, it will have an impact on the anonymous system. serious consequence;

[0008] (4) Poor scalability. The onion routing technology adopts a centralized encapsulation form. Before conducting anonymous communication, the onion router agent needs to negotiate keys with all selected onion routers. From the perspective of negotiation process and key management, this Centralized management is difficult to adapt to large-scale systems

However, most of the current wireless network access technologies do not consider the anonymity of the system. It is especially obvious that the content of both parties in the system can be easily obtained through the Internet. Even if encryption is used, it can still be obtained through Perform traffic analysis on the network to obtain information about who is communicating with whom in the system, what is the amount of communication, and how often is the communication
