For shared key authentication, the error described below is ().

For skinny AP, The shared key is preset in AC middle

After adopting shared key authentication, you must use WEP Encryption

The shared secret requires users and AP Use the same shared secret

For skinny AP, The shared key is preset in AC middle

The disadvantages of shared keys are poor scalability and not very secure

CCMP Encryption ratio TKIP Encryption security is high because of ().

A more complex encryption algorithm is used

Added a key distribution mechanism, no longer using a single key

A more complex encryption algorithm is used

Added message integrity check mechanism
