Summary:A method for providing multicast frames in a Multi-Dwelling Unit (MDU) is provided herein. An Access Point (AP) can receive a join request from a first client device. The AP can generate a Group Master Key (GMK) from the Pre-Shared Key (PSK) associated with a Basic Service Set (BSS) that includes the first client device. The AP can then derive a Group Transient Key (GTK) from the GMK. The AP may then send the GTK to the first client device. Thereinafter, the AP can send multicast frames to the first client device encrypted by the GTK. The first client device can decrypt the multicast frames with the GTK. However, a second client device, that does not share the PSK, may receive the multicast frame but cannot decrypt the multicast frames.
