A passphrase functions like a password. In WEP security mode, it is further converted by the NWA 
into a complicated string that is referred to as the “key”. This key is requested from all devices 
wishing to connect to a wireless network.

The Pre-Shared Key (PSK) is a password shared by a wireless access point and a client during a 
previous secure connection. The key can then be used to establish a connection between the two 
parties.

Wireless networks can use encryption to protect the information that is sent in the wireless 
network. Encryption is like a secret code. If you do not know the secret code, you cannot 
understand the message. Encryption is the process of converting data into unreadable text. This 
secures information in network communications. The intended recipient of the data can “unlock” it 
with a pre-assigned key, making the information readable only to him. The NWA when used as a 
wireless client employs Temporal Key Integrity Protocol (TKIP) data encryption.

Extensible Authentication Protocol (EAP) is a protocol used by a wireless client, an access point and 
an authentication server to negotiate a connection. 

The EAP methods employed by the NWA when in Wireless Client operating mode are Transport 
Layer Security (TLS), Protected Extensible Authentication Protocol (PEAP), Lightweight Extensible 
Authentication Protocol (LEAP) and Tunneled Transport Layer Security (TTLS). The authentication 
protocol may either be Microsoft Challenge Handshake Authentication Protocol Version 2 
(MSCHAPv2) or Generic Token Card (GTC).

Further information on these terms can be found in

Remote Authentication Dial In User Service (RADIUS) is a protocol that can be used to manage user 
access to large networks. It is based on a client-server model that supports authentication, 
authorization and accounting. The access point is the client and the server is the RADIUS server.
