Unauthorized Access and Privacy

The 802.11 standard uses the wired equivalent privacy (WEP) protocol.
This protocol is intended to provide authentication (prevent unauthorized
access) and privacy (prevent data compromise and data tampering)
equivalent to that in a wired connection, but the 40-bit key is too
short to prevent data compromise. Additional points of concern about
WEP and the standard are:


The 24-bit WEP initialization vector (IV) is too small to prevent
repeated use of a cipher stream.

The manner in which the IV is used is not specified in the standard.

The integrity check value (ICV) is useless for detecting alteration of
frames.

SSID data is not protected by encryption.
