WLAN Security Solution Design And Implementation

WLAN is a combination of computer networks and wireless communications technology. As unique to the open wireless network, the security problem has been the focus of the industry. This thesis lucubrate WLAN security protocol and realize the Security Authentication Module in AP(access point),then put forward an improved solution for application of WAPI in operation-level network.This thesis is divided into five sections.The first part outlines the WLAN network and the project background of this thesis.The second part introduces the basic concepts, standards for the WLAN and WLAN network security risks .The third part analyzes the existing WLAN security protocols in detail, including WEP, IEEE 802.11i and WAPI security mechanism.The fourth part discusses security authentication module design in AP, and realize the IEEE 802.11i and WAPI protocol. First,designs the overall structure of the system. Second,defines the interface between modules. Then design the program flow of the module. Finally, gives an improved solution of WAPI in operation-level network.The fifth part is a brief summary.
