Zusammenfassung:	A data transmitting method of a wireless distribution system (WDS) applying an access point (AP) of a master to encrypt/decrypt data through a wireless protected access (WPA) includes the following steps. First, a second AP is selected as a peer repeater through a user interface of a first AP and a pre-shared key (PSK) is obtained through the user interface. Next, the PSK is set as a pairwise transient key (PTK) and a pairwise master key (PMK) is generated according to the PTK. Then, the PMK is transmitted the second AP. Next, an acknowledgement signal outputted from the second AP is received. Then, the PMK is stored to a group key cache and the data is encrypted/decrypted according to the PMK.
