What is a WEP Key?

Wireless networks broadcast messages using a radio and are thus more susceptible to eavesdropping than wired networks. Wired Equivalent Privacy (WEP) is the first in a line of increasingly secure algorithms that include WPA and WPA2 used to secure IEEE 802.11 wireless networks.

Setting WEP up is usually done from the wireless security tab of your router configuration, this is most often accessed from your computer using the web address http: 92.168.1.1 by default. It consists of a pass-phrase and a key. the pass-phrase is used to generate an encryption key, this is then necessary to use any packets (Bits of data) transferred over the air.

Newer routers allow this configuration to be done through a visual application as well.

WIRELESS To configure the Router as a wireless access point for wireless clients (either stationary or roaming), all you need to do is define the radio channel, the Service Set identifier (SSID), and security options.ADVANCED SETUP 47 Channel and SSID You must specify a common radio channel and SSID (Service Set ID) to be used by the Router and all of your wireless clients. Be sure you configure all of your clients to the same values. SSID: The Service Set ID. This should be set to the same value as the other wireless devices in your network. SSID Broadcast: Broadcasting the SSID on the wireless network for easy connection with client PCs. For security reasons, you should disable SSID broadcast. (Default: Enable) Note: The SSID is case sensitive and can consist of up to 32 alphanumeric characters. Wireless Mode: Set the communication mode for the Router. Default: Mixed (11b+11g)Configuring the Wireless Barricade g Router 48 Transmission Rate: Set the rate of data transmitted from the Router. The lower the data rate, the longer the transmission distance. (Default: Fully Automatic.) Channel: The radio channel through which the Router communicates with PCs in its BSS. (Default: 6) Note: The available channel settings are limited by local regulations. g Nitro: In a crowded 2.4 MHz frequency, the connection speed is much lower than the promised 54 Mbps. The g Nitro implemented by Intersil's Prism Nitro technology dramatically enhances your wireless network speeds. It provides up to 50% more throughput in 11g only environment, and improves network throughput by 3 times in mixed mode.ADVANCED SETUP 49 Security If you are transmitting sensitive data across radio channels, you should enable wireless security. Configuring the Wireless Barricade g Router 50 WEP Wired Equivalent Privacy (WEP) encryption requires you to use the same set of encryption/decryption keys for the Router and all of your wireless clients. WEP mode: You can choose disabled, 64-bit or 128-bit encryption. Key Provisioning: Select a key type of static key or dynamic key. Static WEP Key Setting You may manually enter the keys or automatically generate encryption keys. To manually configure the keys, enter 10 digits for each 64-bit key, or enter 26 digits for the single 128-bit key. (A hexadecimal digit is a number or letter in the range 0-9 or A-F.) For automatic 64-bit security, check the box of Passphrase, enter a passphrase and click SAVE SETTINGS. ADVANCED SETUP 51 Four keys will be generated. Choose a key ID (1-4) from the drop-down list or accept the default key. If you use encryption, configure the same keys used for the Router on each of your wireless clients. Note that Wired Equivalent Privacy (WEP) protects data transmitted between wireless nodes, but does not protect any transmissions over your wired network or over the Internet. WPA Wi-Fi Protected Access (WPA) combines Temporal Key Integrity Protocol (TKIP) and 802.1x mechanisms. It provides dynamic key encryption and 802.1x authentication service. With TKIP, WPA uses 48-bit initialization vectors, calculates an 8-byte message integrity code, and generates an encryption key periodically. For authentication, it allows you to use 802.1x authentication for an environment with a RADIUS server installed on your network. Selecting the Pre-shared Key enables WPA to use the pre-shared key in a SOHO network.Configuring the Wireless Barricade g Router 52 Field Default Parameter Description Cypher suite TKIP One of the security mechanism used by WPA for frame body and CRC frame encryption Authentication 802.1X Select the authentication mode. • 802.1X: It is for an enterprise network with a RADIUS server installed. • Pre-shared Key: It is for a SOHO network without any authentication server installed. Pre-shared key type Passphrase (8~63 characters) Select the key type as in pass-phrase or in 64-Hex characters Pre-shared Key none Specify in pass-phrase style or in 64-Hex characters. Group Key Re_Keying Disable The period of renewing broadcast/ multicast keyADVANCED SETUP 53 802.1X Management access will be checked against the authentication database stored on the Router. If an authentication RADIUS server is used, you must specify the secret key of the Message-Authenticator attribute, i.e., Message Digest-5 (MD5), and the corresponding parameters in the RADIUS Server Parameters field for the remote authentication protocol.Configuring the Wireless Barricade g Router 54 • General Parameters • RADIUS Server Parameters Field Default Parameter Description Enable 802.1X Yes Starts using 802.1x security control. Session Idle Timeout 300 seconds Defines a maximum period of time for which the connection is maintained during inactivity. Re-Authentication Period 3600 seconds Defines a maximum period of time for which the RADIUS server will dynamically re-assign a session key to a connected client station. Quiet Period 60 seconds Defines a maximum period of time for which the Router will wait between failed authentications. Server Type RADIUS Selects the authentication server type. Field Defaults Description Server IP 192.168.1.1 The IP address of the RADIUS server. Server Port 1812 UDP port is used for RADIUS authentication messages. Secret Key none Defines a text string on both the RADIUS client and server to secure RADIUS traffic. The RADIUS server requires MD5 Message-Authenticator attribute for all access request messages. The 802.1x authentication scheme is supported by using the Extensible Authentication Protocol (EAP) over the RADIUS server. NAS-ID none Defines the request identifier of the Network Access Server

Wired Equivalent Privacy (WEP) is a deprecated algorithm used to secure IEEE 802.11 wireless networks. Wireless networks broadcast messages using a radio and are thus more susceptible to eavesdropping than wired networks.

Setting WEP up is done from the wireless security tab of your router configuration, this is usually accessed from your computer using the web address http:\\192.168.1.1 by default. It consists of a pass-phrase and a key. the pass-phrase is used to generate an encryption key, this is then necessary to use any packets (Bits of data) transferred over the air.

Beginning in 2001, several serious weaknesses were identified by cryptanalysts with the result that today a WEP connection can be cracked with readily available software within minutes.[2] Within a few months the IEEE created a new 802.11i task force to counteract the problems. By 2003, the Wi-Fi Alliance announced that WEP had been superseded by Wi-Fi Protected Access (WPA), which was a subset of then upcoming 802.11i amendment. Finally in 2004, with the ratification of the full 802.11i standard (i.e., WPA2)

what is a WEP ky


Wired Equivalent Privacy. It is a security code used on some WiFi networks. WEP keys allow a group of devices on a local network (such as a home network) to exchange encoded messages with each other while hiding the contents of the messages from easy viewing by outsiders.

you can generate a key by searching google or try this link
