Embodiment Construction

[0050]After China enforces the Wireless Local Area Network Authentication and Privacy Infrastructure (WAPI) standard, if all wireless access points (APs) in the wireless local area network (WLAN) are upgraded to support WAPI, a large number of existing terminal stations (STAs) will To access the WAPI network, it must also be upgraded to support WAPI. For STAs that have not upgraded or roamed from abroad, they cannot access the WAPI network.

[0051] The present invention adds a method for automatically identifying STAs in the AP, and judges whether the STA supports WAPI through the content of the message. If the AP sends a WAPI message to the STA, it does not receive a WAPI message response, and it receives an 802.1X message. The STA does not support WAPI, but can support 802.1X, so the 802.1X authentication and encryption process is started.

[0052] When the STA does not support the WAPI function, the 802.1X authentication process between the STA and the AP can be initiated ...

Abstract

The invention discloses a method for realizing the compatibility between the WAPI protocol and the 802.1X protocol, so as to solve the problem that non-WAPI terminal stations cannot access the wireless local area network supporting WAPI. The method is as follows: a wireless access point (AP) supporting the WAPI protocol and the 802.1X protocol sends an authentication activation message to a terminal station (STA); the AP judges whether the STA supports the WAPI protocol, and if so, between the AP and the STA according to the WAPI-regulated Otherwise, the WAPI authentication attempt is terminated between the AP and the STA, and authentication is performed according to the procedures specified in 802.1X.

Description

technical field [0001] The invention relates to wireless local area network technology, in particular to a method for realizing compatibility between WAPI protocol and 802.1X protocol. Background technique [0002] Wireless local area network (WLAN) is mainly used to transmit Internet Protocol (IP) packet data packets, that is, access point (AP) provides wireless access for user terminals, and then completes the transmission of IP packets through network controllers and connecting devices. [0003] WLAN includes a variety of different technologies. Currently, a widely used technical standard is IEEE802.11b, which uses the 2.4GHz frequency band and has a maximum data transmission rate of up to 11Mbps. Also using this frequency band are IEEE 802.11g and Bluetooth (Bluetooth) technology, among them, the highest data transmission rate of 802.11g can reach 54Mbps. Other new technologies such as IEEE 802.11a and ETSI BRAN Hiperlan2 both use the 5GHz frequency band, and the highes...
