comment 802.1X and 802.11- can you prevent a rogue access point from the start?
If I send you a phone number and tell you it's microsoft, you ring and the person answering says he works for microsoft, that doesnt prove its microsoft, does it? If i went on google and that said the number is microsoft- that would prove it..... ?

@David, I thought the server returns a digest from the client, signed with it's private key. The client decrypts this using the server's public key, read's its own digest and therefore knows the sender was the person who received the digest? However, how does the client know which public key to use on the encrypted digest?

@David, as I understand it 802.1X provides mutual authentication using public key cryptography. If the server provides the public key then that defeats the point of the key being public, surely i should be obtaining it not from the server but from somewhere.... public so that I know it IS their public key? I dont understand how this is done on 802.1X for wireless?
