An auditor reviewing a municipal RSN profile asks what 'group cipher' versus 'pairwise cipher' means at a high level. What is the correct contrast?
Select an answer to reveal the explanation.
Short Explanation
Unicast is the private hallway between one laptop and the AP—that is the pairwise key. Broadcast is the building loudspeaker—that needs the group key. Mix those up and you misread what confidentiality actually covers.
Full Explanation
In RSN deployments, pairwise transient material protects unicast data between a station and the AP, while the group temporal key protects broadcast and multicast frames delivered to multiple receivers. Auditors should map cipher suite fields to that unicast-versus-group split rather than treating the labels as synonyms. Misreading the distinction can hide weak group-cipher choices even when pairwise CCMP looks correct.
