6. Wireless Reference Table Wireless Reference Table Remote Authentication Dial In User Service WEP was initially intended to provide a level of confidentiality on a wireless network that was comparable to a wired infrastructure WEP does not allow for any true authorization only encryption and does not protect users or devices from each other on the network There are two main WEP types WEP Open System Standard WEP All data transmissions are encrypted with the WEP key No attempt is made to authorize the Client device WEP Shared Key In Shared Key a very insecure attempt to autho rize the device is attempted The actual WEP encryption key is sent to the host usually the access point to verify the identity of the device This exposes the enciphering key to the network and should not be used In a WEP enabled environment each client holds the common network encryption keys which can be either a 40 bit key for 64 bit encryption or a 104 bit key for 128 bit encryption These keys are common to all devices on the network and are used to encrypt all data transmissions Because each network packet is encrypted with the same key and because of flaws in the actual cipher WEP is no longer considered secure and an attacker depending on network traffic could determine the network encryption keys by eavesdropping on the transmissions It has been demonstrated in a controlled environment that these attacks can take as little
