Shared key authentication
802.11 network authentication method in which the AP sends the client device a challenge text packet that the client
must then encrypt with the correct WEP key and return to the AP. If the client has the wrong key or no key,
authentication will fail and the client will not be allowed to associate with the AP. Shared key authentication is not
considered secure, because a hacker who detects both the clear-text challenge and the same challenge encrypted
with a WEP key can decipher the key.
