Question

In a court-house WLAN design workshop, staff confuse PMK, PTK, and GTK roles. Which statement correctly maps the key hierarchy concepts?

Accepted Answer

The PMK is the master key material from which the per-session PTK is derived for unicast, while the GTK protects group/broadcast traffic to associated stations — PMK is the master dough; PTK is the personal loaf for your unicast chat with the AP; GTK is the shared basket for group/broadcast bites. Mix those labels and troubleshooting becomes a food fight.

Answer

The GTK encrypts only EAPOL-Start frames, while the PMK encrypts all broadcast video streams end-to-end across the Internet

Answer

The PTK is the long-lived master shared by every station on the SSID, and the PMK is freshly derived per broadcast frame

Answer

All three names refer to identical keys rewritten three times in the beacon for redundancy
