in SAE, what do the pair use a complex multistage process to prove to one another that they possess?

Answer 12

The PMK, pairwise master key

Question 13

What does the complex handshake in SAE do?

Answer 13

Makes it hard to intercept packets in order to extract an identifiable authentication key.

in what wpa protocol does OWE replace EAP with a solution that encrypts and authenticates all wireless traffic?

Answer 27

WPA3

Question 28

What wpa protocol replaces wifi passwords by assigning a unique key to each device that has permission to access the network? Repairing the experience wifi users have in open, public networks. Restaurants, coffee shop, mall, etc

Answer 28

WPA3 OWE

Question 29

How does WPA3 improve upon the wpa2 wifi protected setup (wps) encryption technology between wireless devices and routers?

Answer 29

Question 32

in HMAC with SHA, what is compared to make sure they match?

Answer 32
