The Study And Implement Of IPSec In 3G Wireless Router

With the 2009 domestic release of 3G licenses, China has entered into the era of 3G formally. Compared with the previous 2.5G networks,3G high-speed wireless access network provides the best solution for the internet wireless access of mobile network. Thus it derived from a large number of 3G terminal equipment. This paper studies the 3G wireless router, which applies the external network with 3G network access and the intranet access with WIFI. As a full wireless network device operating mode the emergence of the people has been successfully applied to mobile business office, small business office, bank ATM machines, wireless monitoring, network television sets and other occasions. So this helps remove the last network, wiring and other complex procedures. Among these various applications, ATM machines/POS machines, mobile network data transmission and mobile wireless data transmission security are particually important.This paper is based on the open-source organization which makes the realization of IPSec VPN. At the same time, using GoAhead web server, the router can realize a simple Web configuration and management. Those are the important part of the 431R router. In mobile business office, ATM machines wireless monitor, wireless VPN tunnels enable the encryption of data wireless communications which is built by the IPSec sub-modules. Increasing the security of data transmission, because of this the customers praise it.This paper firstly introduces the hardware and software platform for 3G wireless router, and then gradually introduces the IPSEC protocol security system, a detailed analysis, OpenS /WAN source code of the overall framework and in-depth analysis of 3G router interconnection to achieve, OpenS/WAN routers, web migration, and server implementation and configuration of the router sub-module test IPSEC. In the end, it summarizes the main work of this test and presents some problems and def iciences of the 3G wireless router. Besides, this paper gives us an outlook of future work directions.
