The Security Screen - ZyXEL Communications 802.11b/g Wireless Access Point NWA-1100 User Manual

• WPA2-PSK-MIX. This commands the ZyXEL Device to use either WPA-PSK or
WPA2-PSK depending on which security mode the wireless client uses.
In Bridge and Bridge + AP operating modes, the only available security modes
are WEP and WPA2-PSK.
Passphrase
A passphrase functions like a password. In WEP security mode, it is further converted by the
ZyXEL Device 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.
PSK
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.
Encryption
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 ZyXEL
Device when used as a wireless client employs Temporal Key Integrity Protocol (TKIP) data
encryption.
EAP
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 ZyXEL Device 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).
