<p>Provided are a data transmission method, an access point and a station. The method comprises: generating a key; sending the key to a station; receiving a downlink data request frame; according to the key, verifying the downlink data request frame and obtaining a verification result; and if the verification result is that the downlink data request frame is valid, sending downlink data to the station. In the embodiments of the present invention, by generating a key and sending the key to a station, and after a downlink data request frame is received, sending downlink data to the station if it is verified that the downlink data request frame is valid according to the key, a third party station can be prevented from pretending to be the station to steal the downlink data, thereby ensuring the network security.</p> |
