Wired Equivalent Privacy
This is the original encryption standard for 802.11 wireless networks. Some cards only support 64 bit encryption, others support 64 and 128 bit encryption. Some manufacturers have mad their own variations with up to 256bit encryption. A flaw was found in early implementations of this standard that allowed the key to be discovered by sniffing a few hundred megabytes of traffic and running it through a cracking tool. This flaw should be fixed in reccently manufacturered devices.
Several alternative encryption protocols have been created for wireless networking to address the deficiencys of WEP. Cisco’s LEAP, the chinese standard WAPI and wifi protected access.
Wifi networks can be secured using an encrypted VPN but this is timeconsuming to set up.
