WEP
WEP (Wired Equivalent Privacy) is a standard for encrypting data before it is transmitted.
This is desirable because it is impossible to prevent snoopers from receiving any data which
is transmitted by your Wireless Stations. But if the data is encrypted, then it is meaningless
unless the receiver can decrypt it.
If WEP is used, the Wireless Stations and the Access Point must have the same security
settings for each of the following:
WEP
Key
WEP Authentication
WPA/WPA2
WPA/WPA2 (Wi-Fi Protected Access) is more secure than WEP. It uses a "Shared Key" which allows
the encryption keys to be regenerated at a specified interval. There are several encryption options:
TKIP, AES, TKIP-AES and additional setup for RADIUS is required in this method. The most important
features beyond WPA to become standardized through 802.11i/WPA2 are: pre-authentication, which
enables secure fast roaming without noticeable signal latency.
If WPA or WPA2 is used, the Wireless Stations and the Access Point must have the same
security settings.
802.1x
With 802.1x authentication, a wireless PC can join any network and receive any messages
that are not encrypted, however, additional setup for RADIUS to issue the WEP key
dynamically will be required.
64 Bits, 128 Bits.
For 64 Bits encryption, the Key value must
match.
For 128 Bits encryption, the Key value must
match.
Open System or Shared Key.
