Background of this WLAN network technology and the threat of possible risks

after analyzing the pros and cons of the current WLAN several commonly used authentication methods

and finally proposes a more secure and have workable solutions

namely IEEE 802.11i- 2004 international standard as the core

at IEEE802.11 i standard framework

using 802.1X / EAP way to achieve strong joint security network strong authentication

identity authentication

based AES algorithm（FIPS PUB 197-2001） of CCMP data confidentiality and integrity protection.
