WEP network and receive files that are not encrypted. In Open System
authentication, the WLAN client need not provide its credentials to the Access
Point during authentication. Thus, any client, regardless of its WEP keys, can
authenticate itself with the Access Point and then attempt to associate. In effect,
no authentication (in the true sense of the term) occurs.
5.2.2.2.2 Shared Key
WEP uses static shared keys (fixed-length hexadecimal or alphanumeric strings)
that are manually distributed to all clients that want to use the network.
When enabled, you must configure at least one WEP key for the Wi-Fi interface
and all its clients:
Default Key (1 ~ 4) – Sets WEP key values for authentication and encryption. The
user must first choose between ASCII or Hexadecimal keys. At least one key must
be specified. Each WEP key has an index number. The selected key is used for
authentication and encryption on the Wi-Fi interface. Enter key values that match
the key type and length settings. (Default: Hex, 128 bits, no preset value)
»
Key Type - Specifies keys as either ASCII or Hexadecimal values.
»
Key Length - WEP keys can be set as 64 or 128 bits in length.
»
Key - Depending on the selected key length, specify keys as either:
◊
5 or 13 alphanumeric characters, or
◊
10 or 26 hexadecimal digits
5.2.2.3 Temporal Key Integrity Protocol (TKIP)
TKIP is a security protocol used in Wi-Fi Protected Access (WPA). Unlike WEP,
TKIP provides per-packet key mixing, a message integrity check and a re-keying
mechanism. TKIP ensures that every data packet is sent with its own unique
encryption key.
5.2.2.4 WPA/WPA2 Security
WPA is a more powerful security technology for Wi-Fi networks than WEP. It
provides strong data protection by using encryption as well as strong access
controls and user authentication. WPA utilizes 128-bit encryption keys and
dynamic session keys to ensure your wireless network's privacy and enterprise
security.
There are two basic forms of WPA:

WPA Enterprise (requires a RADIUS server)
