Bank Security Wireless Network Design And Implementation

Nowadays, the competition of the commercial banks in china turns more and more intensely. The Services of the bank also require the application of radio network. But the security issues of the radio network hold back the application of radio network in the field of Finance widely.In this article, the existing application situations of the radio network in the field of Finance are observed and analyzed. Following these analysis, we can find out there are two major problems that banks focus on. One is radio network authentication, and the other is data secrety and entirety.So, the architecture of a more secure radio network is designed, and the entire solution of more secure radio network in the field of commercial bank is proposed. In this solution, we design an AAA Authentication Server based on FreeRadius, extend and modify its attributes of standard radius protocol in order to satisfy our special properties of authentication. For second problem, IPSec is adopted to enhance the overall security of the network; secrety and entirety of data are ensured by this VPN.Based on China Union CDMA 2000 1.X, we constructe the secure, flexible and economical virtual private radio network and finally achieve the goal.
