The Pairwise Master Key (PMK) is derived from the pre-shared key or the Extensible Authentication Protocol (EAP) authentication process, not from the group key. The group key is used for encrypting broadcast and multicast traffic, while the PMK is used to derive keys for encrypting unicast traffic between a client and the access point.
