WN-250USB User’s Manual

• AES has been developed to ensure the highest degree of security and authenticity

for digital information. It’s the most advanced solution defined by IEEE802.11i for

security in the wireless network.

EAP Type:

• GTC is an authentication protocol that allows the exchange of clear text

authentication credentials across the network.

• TLS is the most secure of the EAP protocols, but isn’t easy to use. It requires that

digital certificates be exchanged in the authentication phase. The server presents a

certificate to the client and, after validating the server’s certificate, the client presents

a client certificate to the server for validation.

• LEAP is a pre-EAP, Cisco-proprietary protocol with many of the features of EAP

protocols. Cisco controls the ability of other vendors to implement this protocol, so it

should be selected for use only when limited brand choice for client, access-point and

server products is not a concern. Once you’ve set up LEAP authentication, you need

to enter the username and password of your computer.

• PEAP & TTLS are similar to, yet easier than, TLS in that they specify a stand- alone

authentication protocol be used within an encrypted tunnel. TTLS supports any

protocol within its tunnel, including CHAP, MSCHAP, MSCHAPv2 and PAP. PEAP

specifies that an EAP-compliant authentication protocol must be used; this adapter

supports MD5, TLS, GTC (Generic Token Card) and MSCHAPv2. That a client

certificate be required for authentication is optional.

Tunnel: Options are MD5, GTC, TLS and MSCHAP-v2.

Username: This is the certificate username on the RADIUS server.

Identity: This is the user’s identity on the RADIUS server.
