WiFi Slax Wireless Live- v3.1 + Plugins UpdatedWEP is an encryption scheme, based on the RC-4 cipher, that is available on all 802.11a, b and g wireless products.
WEP uses a set of bits called a to scramble information in the data frames as it lves the access point or client adapter and the scrambled message is then decrypted by the receiver. Both sides must have the same WEP , which is usually a total of 64 or 128 bits long. A semi-random 24 bit called an Initialization Vector (IV), is part of the , so a 64 bit WEP actually contains only 40 bits of strong encryption while a 128 bit has 104. The IV is placed in encrypted frames hder, and is transmitted in plain text.
Traditionally, WEP has been a slow and boring process. An attacker would have to capture hundreds of thousands or millions of packets? a process that could take hours or even days, depending on the volume of traffic passing over the wireless network. After enough packets were captured, a WEP program such as Air would be used to find the WEP .
