MD5 authentication is simply a validation of existing user account and password that is stored in
the server with what are keyed in by the user. Therefore, wireless client user will be prompted for
account/password validation every time when he/she is trying to get connected. TLS
authentication is a more complicated authentication, which involves using certificate that is
issued by the Radius server, for authentication. TLS authentication is a more secure
authentication, since not only the Radius server authenticates the wireless client, but also the
client can validate the Radius server by the certificate that it issues. The authentication request
from wireless clients and reply by the Radius Server and Access Point process can be briefed as
follows:
1. The client sends an EAP start message to the Access Point
2.
The Access Point replies with an EAP Request ID message
3.
The client sends its Network Access Identifier (NAI) – its user name – to the Access Point
in an EAP Respond message.
4.
The Access Point forwards the NAI to the RADIUS server with a RADIUS Access Request
message.
5.
The RADIUS server responds to the client with its digital certificate.
6.
The client validates the digital certificate, and replies its own digital certificate to the
RADIUS server.
7.
The RADIUS server validates client’s digital certificate.
8.
The client and RADIUS server derive encryption keys.
9.
The RADIUS server sends the access point a RADIUS ACCEPT message, including the
client’s WEP key.
10.
The Access Point sends the client an EAP Success message along with the broadcast key
and key length, all encrypted with the client’s WEP key.
