Abstract
A method and an apparatus for sending a key on a Wireless Local Area Network (WLAN) is provided. In a scenario where an Access Server is separate from an Access Controller, the Access Controller may send a master key of a specified WLAN station to the AC and trigger the AC to agree with the station on a transient key. The method includes: when receiving the master key of the WLAN station sent from an AAA server, searching a station information table for an IP address of an AC associated with the station; sending a message to the AC to instruct the AC to perform a 4-way handshake with the station to agree on a transient key, where the third message carries the master key of the station, a 4-way handshake triggering bit, and a MAC address of the WLAN station.
