Secure Gateway Between Wireless Network And IP Nets: Development And Implementation

With the fast development of network and communication, the requirements of accessing IP network by mobile equirement, grow very fast. The infomation transportation between IP nes and wireless network do a great contribution to the business system. So the design of secure gateway between these two networks has been hotspot worldwide.Orientated by the typical requirement of secure accessing and info transportation, a server system based on mobile vpn was designed and implemented;the main contribution is as following:(1) Typical secure problem and requirement were analyzied, common solution of secure gateway between IP nets and wireless network were compared.(2) A integrated solution of mobile IPSec VPN was designed and implemented, which can be used in GPRS, CDMA, 802.11. Secure access to business system in IP network by mobile phone were presented, two user authentication module are designed: electronic certification method and double factor dynamic password method, role access control module was realized and unified log system was also implemented(3) According to the tests in the real enviorment, the module function was validated;the feasible and extensible of the architecture was proved.
