3. The 128 bit WEP data encryption method consists of 104 user configurable bits Similar to the forty bit WEP data encryption method the remaining 24 bits are factory set and not user configurable Some vendors allow passphrases to be entered instead of the cryptic hexadecimal characters to ease encryption key entry 128 bit encryption is stronger than 40 bit encryption but 128 bit encryption may not be available outside of the United States due to U S export regulations When configured for 40 bit encryption 802 11 products typically support up to four WEP Keys Each 40 bit WEP Key is expressed as 5 sets of two hexadecimal digits 0 9 and A F For example 12 34 56 78 90 is a 40 bit WEP Key When configured for 128 bit encryption 802 11b products typically support four WEP Keys but some manufacturers support only one 128 bit key The 128 bit WEP Key is expressed as 13 sets of two hexadecimal digits 0 9 and A F For example 12 34 56 78 90 AB CD EF 12 34 56 78 90 is a 128 bit WEP Key Note Typically 802 11 access points can store up to four 128 bit WEP Keys but some 802 11 client adapters can only store one Therefore make sure that your 802 11 access and client adapters configurations match WEP Configuration Options The WEP settings must match on all 802 11 devices that are within the same wireless network as identified by the SSID In general if your mobile clients will roam between access points then all of the 802

SSID In an ad hoc wireless network with no access points the Basic Service Set Identification BSSID is used In an infrastructure wireless network that includes an access point the ESSID is used but may still be referred to as SSID An SSID is a thirty two character maximum alphanumeric key identifying the name of the wireless local area network Some vendors refer to the SSID as network name For the wireless devices in a network to communicate with each other all devices must be configured with the same SSID Authentication and WEP The absence of a physical connection between nodes makes the wireless links vulnerable to eavesdropping and information theft To provide a certain level of security the IEEE 802 11 standard has defined two types of authentication methods Open System and Shared Key With Open System authentication a wireless PC can join any network and receive any messages that are not encrypted With Shared Key authentication only those PCs that possess the correct authentication key can join the network By default IEEE 802 11 wireless devices operate in an Open System network Wired Equivalent Privacy WEP data encryption is used when the wireless devices are configured to operate in Shared Key authentication mode There are two shared key methods implemented in most commercially available products 64 bit and 128 bit WEP data encryption B 2 Wireless Networking Basics 202 10026 01 User Manual for the
