Abstract

The invention discloses a WLAN access authentication method and device. The network side is provided with an authentication service function ASF entity. The method includes: a user equipment UE sends a WLAN key acquisition request to the ASF entity, and receives the WLAN key returned by the ASF entity. key acquisition response, and acquire the WLAN access key carried therein; the UE sends a WLAN key acquisition response to the access point AP, which carries the acquired WLAN access key; the UE, according to the acquired WLAN access key, Enter the key to perform mutual authentication with the AP, and establish a connection with the AP after the authentication is passed. Through the present invention, the user's WLAN access is not limited to the network connection between the AP and the authentication network element at the network side.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a WLAN (Wireless Local Area Network, wireless local area network) access authentication method and device. Background technique [0002] As an extension of the traditional wired network, WLAN can provide a high-speed wireless access solution. WLAN has the characteristics of mobility, high flexibility, scalability and simple installation, so it has been widely used, and operators have also begun to deploy WLAN in large quantities. The internet. [0003] Because WLAN uses infinite electromagnetic waves as a carrier, anyone may eavesdrop or interfere with communication. Therefore, WLAN needs corresponding security mechanisms to ensure the communication security of WLAN network. WLAN security is mainly reflected in access control and data encryption. Among them, access control is used to ensure that only legitimate users can access the network, and data encryption is ...
