IEEE 802.11b WEP Security

The IEEE 802.11b standard includes a Shared Key data privacy mechanism,

called Wired Equivalent Privacy

Features of WEP are:

-

Data encryption using a 64 bit shared key

-

No key distribution mechanism. The shared key (password) must be

distributed manually to all personnel and either be remembered or stored

somewhere on the hard disk.

-

Simple authentication of clients based on a challenge / response mechanism,

using the shared key and the hardware address.
