Wireless Lan Security With 802.1x Protocol In Ap

Unlike wired network, wireless LAN (WLAN) kicks over the traces of wire cable, so it is more convenient and flexible in network construction and user mobility than wired network. Although having these merits, WLAN could not meet actual demands because of low data speed of the initial WLAN. Consequently, WLAN was scarcely-used and known. Exactly due to it, it was data speed, not security, which was focused on.The use of more advanced technologies enables new WLAN standards provide with high data speed that can meet most applications, because of which, WLAN currently becomes popular. Now, IEEE 802.lib WLAN standard is dominant in market. Many studies show, however, that 802.lib has very serious security problems. Wireless media of WLAN has the character of open channel, so it needs higher request in security than wired condition. If security problems can't be addressed, further application of WLAN will be bound to be limited.The paper aims to analyze and generalize security problems of IEEE 802.11 WLAN and to give responding resolutions. In order to make discussion easy, we first describe the idea of 802.11 WLAN in detail, especially exiting security mechanisms. Our focus is the implementation, in access point, of port-based access control protocol 802.Ix. To be understood easy, we introduce the principle of 802. Ix protocol before it's implementation.
