Shared Key

Devices use a

shared master

secret to identify

themselves as

authorized

members of the

network.

Convenient to use in

conjunction with

WEP, since a WEP

key can serve as the

shared

authentication key.

All devices must

have the key.
The shared key

does not change

automatically.

WPA/PSK

Devices use a

single pre-shared

key (PSK) to

identify

themselves as

authorized

members of the

network and to

generate an

encryption key.

The pre-shared key

and the encryption

keys are not

identical.
Allows smaller

networks to use

WPA without the

need for an

authorization

server.

All devices must

have the key.
