During a design review, staff ask how OKC speeds secure reassociation across city APs. What is the core idea?
Select an answer to reveal the explanation.
Short Explanation
OKC keeps a spare set of keys in the campus’s pocket so the next AP can greet a known client without a full EAP redo. That is opportunistic caching, not an open-SSID trick. Killing keys every half minute is the opposite idea.
Full Explanation
Opportunistic Key Caching stores PMK security association state so participating APs can accelerate secure reassociation without repeating full EAP when the cache hits. It is a roaming optimization, not a requirement to disable revocation checking or drop encryption. Misstating OKC as open mid-roam access is incorrect.
