Encryption type
Description
Benefits
Limitations
WEP
encryption
Devices on a
network share a
password, called a
WEP key to encode
and decode data.
Simplest strategy
that provides
encryption.
All devices must
have the key.
The WEP key does
not change
automatically.
WEP encryption
provides less
security than both
AES or TKIP.
AES
Advanced
Encryption Standard
(AES) is a U.S.
government
sponsored
encryption method
that uses a complex
algorithm called
Rijndael.
AES uses
encryption keys to
encode data. AES
automatically
changes the
encryption keys
after a certain time
interval, thus making
the wireless network
less vulnerable to
eavesdropping.
Since the
encryption key
changes
automatically, the
data is more difficult
for eavesdroppers
to decode.
All devices must
have the key.
TKIP
Temporal Key
Integrity Protocol
(TKIP) uses
encryption keys to
encode data. TKIP
automatically
changes the
encryption keys
after a certain time
interval, thus making
the wireless network
less vulnerable to
eavesdropping.
Since the
encryption key
changes
automatically, the
data is more difficult
for eavesdroppers
to decode.
All devices must
have the key.
