Wireless Lan Security; Data Encryption With Wep - TRENDnet TEW-621PC User Manual

Because wireless networks are not as secure as wired networks, its vital that security
settings are clearly understood and applied.

THE SETTINGS YOU ARE APPLING.
DATA YOU SEND CAN BE SEEN BY OTHERS.
The list below shows the possible wireless security levels on your card starting with the most
secure. EAP (Extensible Authentication Protocol) is used for authentication and utilizes
dynamic WEP key exchange. EAP requires interaction with a RADIUS (Remote
Authentication Dial-In User Service) server either on the WAN or the LAN to provide
authentication service for wireless stations.
1. Wi-Fi Protected Access (WPA)
2. IEEE802.1X EAP with RADIUS Server authentication
3. WEP Encryption

ATA NCRYPTION WITH
The WEP (Wired Equivalent Privacy) security protocol is an encryption method designed to try
to make wireless networks as secure as wired networks. WEP encryption scrambles all data
packets transmitted between the card and the access point or other wireless stations to keep
network communications private. Both the wireless stations and the access points must use
the same WEP key for data encryption and decryption.
There are two ways to create WEP keys in your card.
•
Automatic WEP key generation based on a password phrase called a passphrase.
The passphrase is case sensitive. You must use the same passphrase for all WLAN
cards with this feature in the same WLAN.
•
For WLAN cards without the passphrase feature, you can still take advantage of this
feature by writing down the four automatically generated WEP keys from the Security
Settings screen of the wireless utility and entering them manually as the WEP keys in
the other WLAN card(s).
The card allows you to configure up to four WEP keys and only one key is used as the
default transmit key at any one time.
