While documenting the city council chamber SSID, the architect must explain encryption key roles at a design level. Which statement is accurate?
Select an answer to reveal the explanation.
Short Explanation
Unicast is a private hallway conversation—that is pairwise keys. Broadcast is the PA system in the chamber—that is the group key. WPA3 does not send you back to one static WEP key for both jobs.
Full Explanation
In 802.11 RSN designs, pairwise transient keys secure unicast data between a station and an access point, while group keys protect broadcast and multicast frames within the BSS. Designers must understand these roles when reasoning about encryption methods and key hierarchies. Static WEP keys and captive-portal cookies are not substitutes for RSN pairwise/group key concepts. Correct conceptual placement supports sound WLAN security architecture.
