Abstract: Wireless access adds new external intrusion channel while extending conventional wired network. For the new security problem from wired network and wireless extension, the paper proposes an improved security scheme on the basis of 802.11i. The scheme uses CCMP data encryption and 802.1X authentication mechanism integrating digital certificate, USBkey and SSID, to identify supplicant, authenticate wireless devices and implement secure access.

Key words: wireless extension, network perimeter security, 802.11i, 802.1X, USBkey, certification
