How does WEP deauthenticate users?

[Jbees]

I was looking at information on authenticating with WEP and found that the AP sends an unencrypted challenge, then the client is supposed to send the encrypted challenge back. When deauthenticating is the request sent encrypted or unencrypted?

What I'm trying to ask is how does Aireplay do the deauth attack?

Did you read the man page and or their extensive help section on their website?
I bet you can find more info there.
